STARTING AND OPERATING

ENGINE BLOCK HEATER — IF EQUIPPED

The engine block heater warms the engine, and

permits quicker starts in cold weather. Connect

the cord to a standard 110-115 Volt AC

electrical outlet with a grounded, three-wire

extension cord.

The engine block heater must be plugged in at

least one hour to have an adequate warming

effect on the engine.

The engine block heater cord is located:

 6.2L/6.4L Engine — Bundled and strapped in

front of the power distribution center.

ENGINE BREAK-IN RECOMMENDATIONS

The following tips will be helpful in obtaining

optimum performance and maximum durability

for your new SRT Vehicle.

This breaking in occurs mainly during the first

500 miles (805 km) and continues through the

first oil change interval.

It is recommended for the operator to observe

the following driving behaviors during the new

vehicle break-in period:

0 to 100 miles (0 to 161 km):

 Do not allow the engine to operate at idle for

an extended period of time.

 Press the accelerator pedal slowly and not

more than halfway to avoid rapid accelera-

tion.

 Avoid aggressive braking.

 Drive with the engine speed below

3,500 RPM.

 Maintain vehicle speed below 55 mph

(88 km/h) and observe local speed limits.

100 to 300 miles (161 to 483 km):

 Press the accelerator pedal slowly and not

more than halfway to avoid rapid accelera-

tion in lower gears (FIRST to THIRD gears).

 Avoid aggressive braking.

 Drive with the engine speed below

5,000 RPM.

 Maintain vehicle speed below 70 mph

(112 km/h) and observe local speed limits.

300 to 500 miles (483 to 805 km):

 Exercise the full engine RPM range, shifting

manually (paddles or gear shift) at higher

RPMs when possible.

 Do not perform sustained operation with the

accelerator pedal at wide open throttle.

 Maintain vehicle speed below 85 mph

(136 km/h) and observe local speed limits.

WARNING!

Remember to disconnect the engine block

heater cord before driving. Damage to the

110-115 Volt electrical cord could cause

electrocution.

21_WK_S_SU_EN_USC_t.book Page 15

16 STARTING AND OPERATING

(Continued)(Continued)

(Continued)

For the first 1,500 miles (2,414 km):

 Do not participate in track events, sport

driving schools, or similar activities.

NOTE:

Check engine oil with every refueling and add if

necessary. Oil and fuel consumption may be

higher through the first oil change interval.

Running the engine with an oil level below the

add mark can cause severe engine damage.

AUTOMATIC TRANSMISSION

You must press and hold the brake pedal while

shifting out of PARK.

WARNING!

 Never use the PARK position as a substi-

tute for the parking brake. Always apply the

parking brake fully when exiting the vehicle

to guard against vehicle movement and

possible injury or damage.

 Your vehicle could move and injure you and

others if it is not in PARK. Check by trying to

move the transmission gear selector out of

PARK with the brake pedal released. Make

sure the transmission is in PARK before

exiting the vehicle.

 The transmission may not engage PARK if

the vehicle is moving. Always bring the

vehicle to a complete stop before shifting to

PARK, and verify that the transmission gear

position indicator solidly indicates PARK (P)

without blinking. Ensure that the vehicle is

completely stopped, and the PARK position

is properly indicated, before exiting the

vehicle.

 It is dangerous to shift out of PARK or

NEUTRAL if the engine speed is higher than

idle speed. If your foot is not firmly pressing

the brake pedal, the vehicle could accel-

erate quickly forward or in reverse. You

could lose control of the vehicle and hit

someone or something. Only shift into gear

when the engine is idling normally and your

foot is firmly pressing the brake pedal.

WARNING! (Continued)

 Unintended movement of a vehicle could

injure those in or near the vehicle. As with

all vehicles, you should never exit a vehicle

while the engine is running. Before exiting a

vehicle, always come to a complete stop,

then apply the parking brake, shift the

transmission into PARK, and turn the igni-

tion OFF. When the ignition is in the OFF

mode, the transmission is locked in PARK,

securing the vehicle against unwanted

movement.

 When exiting the vehicle, always make sure

the ignition is in the OFF mode, remove the

key fob from the vehicle, and lock the

vehicle.

 Never leave children alone in a vehicle, or

with access to an unlocked vehicle.

Allowing children to be in a vehicle unat-

tended is dangerous for a number of

reasons. A child or others could be seriously

or fatally injured. Children should be

warned not to touch the parking brake,

brake pedal or the transmission gear

selector.

WARNING! (Continued)

21_WK_S_SU_EN_USC_t.book Page 16

STARTING AND OPERATING 17

FUEL ECONOMY (ECO) MODE

The Fuel Economy (ECO) mode can improve the

vehicle's overall fuel economy during normal

driving conditions. Push the “ECO” switch in the

center stack of the instrument panel to activate

or disable ECO mode. A light on the switch

indicates when ECO mode is enabled.

Fuel Economy Mode Switch (SRT Model)

When the Fuel Economy (ECO) Mode is

engaged, the vehicle control systems will

change the following:

 The transmission will upshift sooner and

downshift later.

 The overall driving performance will be more

conservative.

 The transmission will launch (from a stop) in

SECOND gear, and the torque converter

clutch may engage at lower engine speeds

and remain on longer.

 Some ECO mode functions may be tempo-

rarily inhibited based on temperature and

other factors.

 Do not leave the key fob in or near the

vehicle (or in a location accessible to chil-

dren), and do not leave the ignition in the

ACC or ON/RUN mode. A child could

operate power windows, other controls, or

move the vehicle.

CAUTION!

Damage to the transmission may occur if the

following precautions are not observed:

 Shift into or out of PARK or REVERSE only

after the vehicle has come to a complete

stop.

 Do not shift between PARK, REVERSE,

NEUTRAL, or DRIVE when the engine is

above idle speed.

 Before shifting into any gear, make sure

your foot is firmly pressing the brake pedal.

WARNING! (Continued)
