Safety Warnings and Symbols

There are a number of safety cautions in this book. We

use a box and the word CAUTION to tell about things

that could hurt you if you were to ignore the warning.

{CAUTION:

These mean there is something that could hurt

you or other people.

In the caution area, we tell you what the hazard is.

Then we tell you what to do to help avoid or reduce

the hazard. Please read these cautions. If you do not,

you or others could be hurt.

You will also ﬁnd a circle

with a slash through it in

this book. This safety

symbol means “Do Not,”

“Do Not do this” or

“Do Not let this happen.”

iii

Vehicle Damage Warnings

Also, in this manual you will ﬁnd these notices:

Notice: These mean there is something that could

damage your vehicle.

A notice tells about something that can damage the

vehicle. Many times, this damage would not be covered

by your vehicle’s warranty, and it could be costly. But

the notice will tell what to do to help avoid the damage.

When you read other manuals, you might see

CAUTION and NOTICE warnings in different colors

or in different words.

There are also warning labels on the vehicle. They use

the same words, CAUTION or NOTICE.

Vehicle Symbols

The vehicle has components and labels that use

symbols instead of text. Symbols are shown along

with the text describing the operation or information

relating to a speciﬁc component, control, message,

gage, or indicator.

If you need help ﬁguring out a speciﬁc name of a

component, gage, or indicator, reference the

following topics:

• Seats and Restraint Systems in Section 1

• Features and Controls in Section 2

• Instrument Panel Overview in Section 3

• Climate Controls in Section 3

• Warning Lights, Gages, and Indicators in Section 3

• Audio System(s) in Section 3

Front Seats

Manual Seats

{CAUTION:

You can lose control of the vehicle if you try to

adjust a manual driver’s seat while the vehicle

is moving. The sudden movement could startle

and confuse you, or make you push a pedal

when you do not want to. Adjust the driver’s

seat only when the vehicle is not moving.

Lift the bar located under the front of the seat to

unlock it. Slide the seat to where you want it and

release the bar. Try to move the seat with your body

to be sure the seat is locked in place.

1-3

Power Seats

If you have this feature, the power seat controls are

located on the outboard side of the front seat cushions.

The horizontal control adjusts the seat cushion and

the vertical control adjusts the seatback.

• Move the front of the seat control up or down to

adjust the front portion of the cushion.

• Move the rear of the seat control up or down to

adjust the rear portion of the cushion.

• Lift up or push down on the center of the seat

control to move the entire seat up or down.

• To move the seat forward or rearward, slide the

seat control forward or rearward.

• To recline the seatback, press the vertical control

rearward. To raise the seatback, press the vertical

control forward. See Reclining Seatbacks on

page 1-7 for more information.

1-4

Manual Lumbar

If your vehicle has this

feature, there is a knob

located on the outboard

side of the driver’s seat.

Turn the knob counterclockwise to increase lumbar

support and clockwise to decrease lumbar support.

Power Lumbar

Your vehicle may have this feature.

The control is located

on the outboard side

of the seat cushion.

To increase or decrease support, hold the control

forward or rearward. Keep in mind that as your

seating position changes, as it may during long trips,

so should the position of your lumbar support.

Adjust the seat as needed.

1-5

Heated Seats

Your vehicle may have

heated front seats. The

buttons used to control this

feature are located on

the front door armrests.

The engine must be

running for the heated

seat feature to work.

To heat the entire seat, press the horizontal button with

the heated seat symbol. Press the button repeatedly

to cycle through the temperature settings of high,

medium, low and off. The indicator lights above the

button will glow to designate the level of heat selected:

three for high, two for medium, and one for low.

The low setting warms the seatback and seat cushion

until the seat temperature is near body temperature. The

medium and high settings heat the seatback and seat

cushion to a slightly higher temperature. You will be able

to feel heat in about two minutes.

To heat only the seatback, press the button with the

words BACK ONLY. An indicator light on the switch

will glow to designate that only the seatback is being

heated. Additional presses will cycle through the

heat levels for the seatback only. Press the horizontal

button again to heat the whole seat.

The feature will shut off automatically when the ignition

is turned off.

1-6

Reclining Seatbacks

If your vehicle has a manual recliner, lift the lever

located on the outboard side of the seat and push the

seatback rearward to recline the seatback. To return

the seatback to the normal position, lift the lever without

pushing rearward on the seatback and the seatback

will move forward.

If your vehicle has

power seats, the power

reclining seatback

control is located on

the outboard side of

the front seat cushions.

Press the control rearward

to recline the seatback.

Press the control forward

to raise the seatback.

1-7

But do not have a seatback reclined if your vehicle is

moving.

{CAUTION:

Sitting in a reclined position when your vehicle

is in motion can be dangerous. Even if you

buckle up, your safety belts cannot do their

job when you are reclined like this.

The shoulder belt cannot do its job. In a crash,

you could go into it, receiving neck or other

injuries.

The lap belt cannot do its job either. In a crash

the belt could go up over your abdomen. The

belt forces would be there, not at your pelvic

bones. This could cause serious internal

injuries.

For proper protection when the vehicle is in

motion, have the seatback upright. Then sit

well back in the seat and wear your safety belt

properly.

1-8

Head Restraints

Adjust your head restraint so that the top of the

restraint is closest to the top of your head. This position

reduces the chance of a neck injury in a crash.

The head restraints lock into place when raised.

To release the head restraint and lower it, press the

tab located on the top of the seatback.

Rear Seats

Rear Seat Operation

Envoy/Envoy Denali

Your vehicle may have a folding rear seat which lets

you fold the seatbacks down for more cargo space.

Pull up on the loop located where the seat cushion

meets the seatback to fold the seat cushion up and

out of the way. This will allow the seatback to fold ﬂat

and increase the cargo area.

1-9

The rear seatback

levers are located on

the outboard side of

the rear seatbacks.

Pull the seatback toward you as you lift up on the lever.

The head restraint will automatically fold out of the

way when the seatback is folded down.

To raise the seatbacks, lift up the seatbacks and

push on them until they lock into the upright position.

Push and pull on the seatbacks to make sure that

they are latched securely. Then fold the bottom seat

cushion back into place.

To return the head restraint to the upright position,

reach behind the seat and pull the restraint up until it

locks into place. Push and pull on the head restraint to

make sure that it is latched securely.

Safety Belts

Safety Belts: They Are for Everyone

This part of the manual tells you how to use safety

belts properly. It also tells you some things you should

not do with safety belts.

{CAUTION:

Do not let anyone ride where he or she can

not wear a safety belt properly. If you are in a

crash and you are not wearing a safety belt,

your injuries can be much worse. You can hit

things inside the vehicle or be ejected from it.

You can be seriously injured or killed. In the

same crash, you might not be, if you are

buckled up. Always fasten your safety belt,

and check that your passengers’ belts are

fastened properly too.

1-12

{CAUTION:

It is extremely dangerous to ride in a cargo

area, inside or outside of a vehicle. In a

collision, people riding in these areas are more

likely to be seriously injured or killed. Do not

allow people to ride in any area of your vehicle

that is not equipped with seats and safety

belts. Be sure everyone in your vehicle is in

a seat and using a safety belt properly.

Your vehicle has a light

that comes on as a

reminder to buckle up.

See Safety Belt Reminder

Light on page 3-34.

In most states and in all Canadian provinces, the law

says to wear safety belts. Here is why: They work.

You never know if you will be in a crash. If you do have

a crash, you do not know if it will be a bad one.

A few crashes are mild, and some crashes can be so

serious that even buckled up, a person would not

survive. But most crashes are in between. In many of

them, people who buckle up can survive and sometimes

walk away. Without belts they could have been badly

hurt or killed.

After more than 30 years of safety belts in vehicles,

the facts are clear. In most crashes buckling up

does matter...a lot!

1-13

Why Safety Belts Work

When you ride in or on anything, you go as fast as

it goes.

Take the simplest vehicle. Suppose it is just a seat on

wheels.

Put someone on it.
