Starting Your Diesel Engine
Your diesel engine starts differently than a
gasoline engine.
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position
-- that’s
a safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
NOTICE:
Don’t try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when
your vehicle is stopped.
Manual Transmission
Move your shift lever to NEUTRAL and hold the
clutch pedal to the floor while starting the engine. Your
vehicle won’t start if the clutch pedal is not all the way
down
-- that’s a safety feature.
Starting Your Engine
1. Turn your ignition key to RUN.
Observe the WAIT TO START light. (This light may
not come on if the engine is hot.)
2. As soon as the WAIT TO START light goes off,
IMMEDIATELY turn the ignition key to START.
When the engine starts, let go of the key.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor.
NOTICE:
If the WAIT TO START light stays on, it means
that your vehicle could have one of several
problems, so you should have it serviced
right away.
2-3
3. If the engine does not start after 15 seconds of
cranking, turn the ignition key to OFF. Wait one
minute for the starter to cool, then try the same
steps again.
If you’re trying to start your engine after you’ve run
out of fuel, follow the steps in “Running Out of Fuel.”
See “Diesel Fuel Requirements and Fuel System” in
the Index.
When your engine is cold, let it run for a few minutes
before you move your vehicle. This lets oil pressure
build up. Your engine will sound louder when it’s cold.
NOTICE:
If you’re not in an idling vehicle and the engine
overheats, you wouldn’t be there to see the
coolant temperature gage. This could damage
your vehicle. Don’t let your engine run when
you’re not in your vehicle.
Cold Weather Starting (Diesel Engine)
The following tips will help you get good starting in
cold weather.
Use the recommended engine oil when the outside
temperature drops below freezing. See “Engine Oil”
in the Index. When the outside temperature drops
below 0 F (
-18 C), use of the engine coolant heater
is recommended.
See “Diesel Fuel Requirements and Fuel System”
in the Index for information on what fuel to use in
cold weather.
2-4
If Your Diesel Engine Won’t Start
If you’ve run out of fuel, look at “Running Out of Fuel.”
See “Diesel Fuel Requirements and Fuel System” in
the Index.
If you’re not out of fuel, and your engine won’t start,
do this:
Turn your ignition key to RUN. IMMEDIATELY after
the WAIT TO START light goes off, turn the ignition
key to START.
If the light doesn’t go off, wait a few seconds, then try
starting your engine again. And, see your dealer as soon
as you can for a starting system check.
If the light comes on and then goes off and you know
your batteries are charged, but your engine still won’t
start, your vehicle needs service.
If the light does not come on when the engine is cold,
your vehicle needs service.
If your batteries don’t have enough charge to start your
engine, see “Battery” in the owners manual.
Be sure you have the right oil for your engine, and that
you’ve changed the oil at the proper times. If you use
the wrong oil, your engine may be harder to start.
If the engine starts, runs a short time, then stops,
your vehicle needs service.
CAUTION:
Do not use gasoline or starting “aids,” such as
ether, in the air intake. They could damage your
engine. There could also be a fire, which could
cause serious personal injury.
Engine Coolant Heater
In very cold weather, 0 F (-18 C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the passengers side of the engine
compartment, near the right side engine mount.
3. Plug it into a normal, grounded 110
-volt AC outlet.
2-5
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
110
-volt AC outlet. If the cord won’t reach,
use a heavy
-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don’t, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature. You may wish to use your coolant heater
to improve ease of starting at temperatures between
0 F (
-20 C) and -20 F (-29 C). Keep the coolant
heater plugged in for a minimum of 4 hours. However,
above
-20 F (-29 C) use of the coolant heater shouldn’t
be necessary. At temperatures below
-20 F (-29 C)
the coolant heater should remain plugged in for at least
8 hours. It will not harm either the coolant heater or
the vehicle to leave the coolant heater plugged in longer
than the times stated. Be sure to remove and store the
cord before starting the engine. See “Diesel Fuel
Requirements and Fuel System” in the Index for
information on what fuel to use in cold weather.
2-6
Instrument Panel Cluster
United States version shown, Canada similar.
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast you’re
going, about how much fuel you have and many other things you’ll need to know to drive safely and economically.
2-7
Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working. If you
are familiar with this section, you should not be
alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They’re a big help.
Your vehicle may also have a message center that works
along with the warning lights and gages. See “Message
Center” in the Index.
2-8
Malfunction Indicator Lamp
(Service Engine Soon Light)
(Check Engine Light)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, timing and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON
light comes on to indicate when service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transmission,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle’s emission controls
and may cause the SERVICE ENGINE SOON
or CHECK ENGINE light to come on.
Modifications to these systems could lead to
costly repairs not covered by your warranty.
This may also result in a failure to pass a
required Emission Inspection/Maintenance test.
2-9
If the Light Comes On
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If it doesn’t, have it repaired. This light will
also come on if an emission control system malfunction
has been detected on your vehicle. Dealer or qualified
service center diagnosis and service may be required.
You also may be able to correct the emission system
malfunction by considering the following:
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line. The system can detect
this. Adding fuel should correct this condition. It will
take a few driving trips to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or may
begin programs to inspect the emission control equipment
on your vehicle. Failure to pass this inspection could
prevent you from getting a vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection.
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON or CHECK ENGINE
light is on or not working properly.
Your vehicle will not pass this inspection if the
OBD (on
-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
2-10
Wait To Start Light
Your diesel engine has a
glow plug system to aid in
starting your vehicle.
An instrument panel WAIT TO START light shows
that the system is functioning properly and tells you
when the engine is ready to be started.
For more information, see “Starting Your Diesel
Engine” in the Index.
Fuel Gage
When the ignition is on,
the fuel gage shows you
approximately how much
fuel you have left in
your tank.
The gage will first indicate E (Empty) before you are
out of fuel, but you should get more fuel as soon
as possible.
2-11
Listed are four situations you may experience with your
fuel gage:
At the gas station, the fuel pump shuts off before the
gage reads F (Full).
It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to fill
the tank.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to E (Empty) when you
turn off the ignition.
None of these indicate a problem with the fuel gage.
For information on how to fill your fuel tank, see “Fuel,
Filling Your Tank” in the Index.
For your fuel tank capacity, see “Fuel, Tank Capacity”
in the Owners Manual.
Your vehicle also has a fuel cooler. To clean, power
wash the bottom of the vehicle.
Message Center
The message center is located above the transmission
temperature gage (if equipped) on the instrument panel
cluster. It gives you important safety and maintenance
facts. When you turn the ignition on, the entire center
lights up for just a few seconds. (The battery display
will stay on while the key is in RUN until the engine
is started.)
2-12
Reduced Engine Power
On diesel engines,
a computer monitors
the operation of the
electronic accelerator.
If this message comes on while you are driving, the
computer is indicating that your vehicle has a problem.
You should take your vehicle in for service soon.
Water in Fuel
This light will come on to
warn you if there is water
in the diesel fuel system.
For more information on how this message works, see
“Diesel Fuel Requirements and Fuel System” in
the Index.

Engine Overheating
You will find a coolant temperature gage on the instrument
cluster. In addition, the message center has the following
warnings that may appear. LOW COOLANT, CHECK
COOLANT TEMP and ENGINE OVERHEATED.
See your owners manual for more information.
If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire.
You or others could be badly burned. Stop your
engine if it overheats, and get out of the vehicle
until the engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not
be covered by your warranty.
5-3
If No Steam Is Coming From Your Engine
If you get an engine overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high
-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” in the
Owners Manual.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If you have an air conditioner and it’s on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving -- DRIVE (D).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there’s still no sign of steam, push down the
accelerator until the engine speed is about twice as fast
as normal idle speed for at least three minutes while
you’re parked. If you still have the warning, turn off
the engine and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get service
help right away.
5-4
Cooling System (Diesel Engine)
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Surge Tank
B. Coolant Surge Tank Pressure Cap
C. Engine Fan
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
When the engine is cold,
the coolant level should be
at or above the FILL COLD
mark. If it isn’t, you may
have a leak in the radiator
hoses, heater hoses,
radiator, water pump or
somewhere else in the
cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you do, you can be burned.
Don’t run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
5-5
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL is
not covered by your new vehicle warranty.
If there seems to be no leak, start the engine again. See if
the engine cooling fan speed increases when idle speed is
doubled by pushing the accelerator pedal down. If it
doesn’t, your vehicle needs service. Turn off the engine.
How to Add Coolant to the Coolant
Surge Tank
NOTICE:
The diesel engine has a specific coolant fill
procedure. Failure to follow this procedure
could cause your engine to overheat and be
severely damaged.
If you haven’t found a problem yet, but the coolant level
isn’t at or above the FILL COLD mark, add a 50/50
mixture of clean, drinkable water and DEX-COOL
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure cap, is
cool before you do it. See “Engine Coolant” in the Index
for more information.
