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.”

4

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

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.

If your vehicle has a manual bucket or a split

bench seat, you can adjust the seat forward or

rearward with the bar located under the front of the

seat cushion.

Lift the bar to unlock the seat. 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.

9

Power Seats

If the vehicle has power seats, the controls used

to operate them are located on the outboard

side of the seats.

To adjust the seat, do any of the following:

• Move the seat forward or rearward by sliding

the control forward or rearward.

• Raise or lower the front part of the seat

cushion by moving the front of the control up

or down.

• Raise or lower the rear part of the seat

cushion by moving the rear of the control up

or down.

• Raise or lower the entire seat by moving the

entire control up or down.

If the seats have power reclining seatbacks, the

control is located behind the power seat control on

the outboard side of the seats. See “Power

Reclining Seatbacks” under Reclining Seatbacks

on page 15.

Your vehicle may have a memory function which

allows seat settings to be saved and recalled.

See Memory Seat, Mirrors, and Pedals on page 13

for more information.

Recline, and Power Lumbar shown

10

Power Lumbar

If the seats have power lumbar, the controls used

to operate this feature are located on the

outboard side of the seats.

• To increase lumbar support, press and hold

the front of the control.

• To decrease lumbar support, press and hold

the rear of the control.

• To raise the height of the lumbar support,

press and hold the top of the control.

• To lower the height of the lumbar support,

press and hold the bottom of the control.

Release the control when the lower seatback

reaches the desired level of lumbar support.

Your vehicle may have a memory function which

allows seat settings to be saved and recalled.

See Memory Seat, Mirrors, and Pedals on page 13

for more information.

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.

11

Heated Seats

If the seats have the

heated seat feature, the

buttons used to

control this feature are

located on the front

doors near the

door handle.

I(Heated Seatback): Press this button to turn

on the heated seatback.

The light on the button will come on to indicate

that the feature is working. Press the button

to cycle through the temperature settings of high,

medium, and low and to turn the heat to the

seatback off. Indicator lights below the button show

and low and to turn the heat to the seat off.

Indicator lights above the button will show the level

of heat selected: three for high, two for medium,

and one for low.

The heated seats will be canceled ten seconds

after the ignition is turned off. If you want to

use the heated seat feature after you restart your

vehicle, you will need to press the appropriate

heated seat or seatback button again.

12

Memory Seat, Mirrors, and Pedals

Your vehicle may have the memory package.

The controls for this

feature are located on

the driver’s door

panel, and are used to

program and recall

memory settings for the

driver’s seat, outside

mirrors, and the

adjustable throttle and

brake pedal feature

if your vehicle has it.

To save your positions in memory, do the following:

1. Adjust the driver’s seat, including the

seatback recliner and lumbar, both outside

mirrors, and the throttle and brake pedals to a

comfortable position.

See Outside Power Mirrors on page 164 and

Adjustable Throttle and Brake Pedal on

page 140 for more information.

Some mirrors might not function with the

memory feature.

2. Press and hold button 1 until two beeps

sound through the driver’s front speaker

to let you know that the position has been

stored.

A second seating, mirror, and throttle and brake

pedal position can be programmed by repeating

the above steps and pressing button 2.

To recall the memory positions, the vehicle must

be in PARK (P). Press and release either button 1

or button 2 corresponding to the desired driving

position. The seat, outside mirrors, and adjustable

throttle and brake pedals will move to the position

previously stored. You will hear a single beep.

If you use the remote keyless entry transmitter to

enter your vehicle and the remote recall memory

feature is on, automatic seat, mirror, and

adjustable pedal movement will occur. See

“MEMORY SEAT RECALL” under DIC Vehicle

Customization (With DIC Buttons) on page 264

for more information.

To stop recall movement of the memory feature at

any time, press one of the power seat controls,

memory buttons, power mirror buttons, or

adjustable pedal switch.

13

If something has blocked the driver’s seat and/or

the adjustable pedals while recalling a memory

position, the driver’s seat and/or the adjustable

pedals recall may stop working. If this happens,

press the appropriate control for the area that

is not recalling for two seconds, after the

obstruction is removed. Then try recalling the

memory position again by pressing the appropriate

memory button. If the memory position is still

not recalling, see your GM dealer for service.

Easy Exit Seat

The control for this feature is located on the

driver’s door panel between buttons 1 and 2.

With the vehicle in PARK (P), the exit position can

be recalled by pressing the exit button. You will

hear a single beep. The driver’s seat will

move back.

If the easy exit seat feature is on in the Driver

Information Center (DIC), automatic seat

movement will occur when the key is removed

from the ignition. See “EASY EXIT SEAT” under

DIC Vehicle Customization (With DIC Buttons)

on page 264 for more information.

Further programming for the memory seat feature

can be done using the DIC. You can select or

not select the following:

• The automatic easy exit seat feature

• The remote memory seat recall feature

For programming information, see DIC Vehicle

Customization (With DIC Buttons) on page 264.

Reclining Seatbacks

Manual Reclining Seatbacks

{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.

{CAUTION:

If the seatback is not locked, it could

move forward in a sudden stop or crash.

That could cause injury to the person

sitting there. Always push and pull on the

seatback to be sure it is locked.

If the seats have manual reclining seatbacks, the

lever used to operate them is located on the

outboard side of the seat(s).

To recline the seatback, do the following:

1. Lift the recline lever.

2. Move the seatback to the desired position,

then release the lever to lock the seatback

in place.

3. Push and pull on the seatback to make sure it

is locked.

15

To return the seatback to an upright position, do

the following:

1. Lift the lever fully without applying pressure to

the seatback and the seatback will return to

the upright position.

2. Push and pull on the seatback to make sure it

is locked.

Power Reclining Seatbacks

If the seats have power reclining seatbacks, the

control used to recline them is located on the

outboard side of the seat behind the power seat

control.

• To recline the seatback, tilt the top of the

control rearward.

• To bring the seatback forward, tilt the top of

the control forward.

Driver’s Seat with Power Seat Control, Power

Recline, and Power Lumbar shown

16

{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.

Do not have a seatback reclined if your vehicle is

moving.

17

Head Restraints

Adjust the head restraint so that the top of the

restraint is at the same height as the top of

the occupant’s head. This position reduces the

chance of a neck injury in a crash.

Pull the head restraint

up to raise it. To lower

the head restraint,

press the release

button (A), located on

the top of the seatback,

while you push the

head restraint down.

The front seats may have head restraints that also

tilt forward and rearward.

To tilt the head restraint, grasp the top of the

restraint while pressing the button (B), located on

the right hand side of the head restraint, and

move it forward or rearward until the desired

locking position is reached. Try to move the head

restraint after the button is released to make

sure that it is locked in place.

The second row seats may have head restraints

that can be adjusted up and down, but they do

not tilt.

18

Center Seat

Your vehicle may have a front center seat. The

seatback doubles as an armrest and cupholder/

storage area for the driver and passenger when the

center seat is not used. Do not use it as a seating

position when the seatback is folded down.

For information on safety belts for this position,

see Center Front Passenger Position on page 53.

Rear Seats

Heated Seats

If the rear seats have

the heated seat feature,

the buttons used to

control this feature are

located on the Rear

Seat Audio (RSA) panel.

M (Heated Seat): To heat the seat cushion,

press the button with the heated seat symbol.

A heated seat symbol will be shown in the RSA

display to indicate that the feature is on. Press the

button to cycle through the temperature settings

of high, medium, and low, and to turn it off.

Indicator bars next to the symbol will designate

the level of heat selected: three for high,

two for medium, and one for low.

The heated seats will be canceled ten seconds after

the ignition is turned off. If the vehicle is restarted,

the heated seat button will need to be pressed

again to restart the feature.

60/40 Split Bench Seat

(Second Row)

If your vehicle has a 60/40 split bench, the seat(s)

can be folded for additional cargo space or

folded and tumbled for easy entry and exit to the

third row seats, if your vehicle has them. These

seats will have either the manual fold and tumble

feature or the automatic seat release fold and

tumble feature.

Manual Fold and Tumble Feature

Folding and Tumbling the Seat(s)

To fold and tumble the seat, do the following:

1. Make sure that there is nothing under, in front

of, or on the seat.

Notice: Folding a rear seat with the safety

belts still fastened may cause damage to the

seat or the safety belts. Always unbuckle

the safety belts and return them to their normal

stowed position before folding a rear seat.

2. Lift the lever, located on the outboard side of

the seat, to release the seatback.
