Sierra Owner’s Manual

Welcome

This manual was prepared to acquaint you with the operation and

maintenance of your

manuals from other manufacturers like body builders or special equipment

companies. We urge you to review all these publications carefully. This

will

help you enjoy safe and trouble-free operation of your vehicle.

When it comes to service, keep in mind that your GMC Truck dealer knows

your vehicle best and is interested in your complete satisfaction. Your dealer

invites you to return

for

all of your service needs both during and after the

warranty period.

Remember,

if

you have a concern and need help handling

it

to your

satisfaction see the procedure in Section 8,

or

in the GMC Truck Warranty

and Owner Assistance Information booklet.

Thanks

choosing a GMC Truck product. We value you as a member of

the GMC Truck family. We want to assure you of our continuing interest in

your pleasure and satisfaction with your vehicle.

This

Manual

Safety

Warnings

and

Symbols

You will find a number of safety cautions in this book. We use yellow and

the word

CAUTION

to tell you about things that could hurt you if you were

to

ignore the warning.

These mean there is something that could hurt you

or

other people.

In the yellow 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

don’t,

you

or

others could be hurt.

You will also find a red circle with

a

slash through it in this book. This safety

symbol means “Don’t,’’ “Don’t

do

this,”

or

“Don’t let this happen.”

Vehicle Damage Warnings

Also, in this book you will find these blue notices:

I

?se mean there is something that could damage your vehicle.

In the blue notice area, we tell you about something that can damage your

vehicle. Many times, this damage would not be covered by your warranty, and

it could be costly. But the notice will tell you 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. In this manual, we’ve used

the familiar words and colors that General Motors has used for years.

You’ll also see warning labels on your vehicle. They use the same colors,

and the words CAUTION

or

NOTICE.

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

don’t want to. Adjust the driver’s seat only when the vehicle is not

moving.

I

K2102

Slide the lever at the front of the seat toward your door

to

unlock

it.

Slide

the seat

to

where you want

it.

Then release the lever and try

to

move the

seat with your body,

to

make sure the seat

is

locked into place.

-

To

adjust the seatback,

lift

the front

of

this lever.

If

your vehicle has an easy

entry seat, your passenger seatback lever will be slightly larger, but will work

the same way. Release the lever

to

lock the seatback where you want it. Pull

up on the front

of

the lever and the seatback will go to an upright position.

Don’t have a seatback reclined

if

Ir

Sitting in a reclined positiin when

your

vehicle

is

in motion

can.

be

4

dangerous.

Even

if

you buckle

up,

your

safety

belts

can’t

do

their

job

when you’re reclined like this.

The

shoulder

belt

can’t

do

its job because it won’t

be

against your

body. Instead, it

will

be

in

front

of

you. In a crash you

could

go

into

it,

receiving

neck

or

other injuries.

The

lap belt can’t

do

its

job

either. In

a

crash the

belt could

go

up

ov0f

your abdomen. The belt forces would

be

there, not at

your

petvic

bones.

This

could

cause

serious internal injuries,

For

proper protection when the vehicle is in motion,

have

the

seat-

back

upright.

Then sit well

back

in the

seat

and

wear

your

safety

belt

properly.

Head Restraints

I

AN102016

Slide the head restraint up or down

so

that the top of the restraint

is

closest

to the top of your ears.

This position reduces the chance of a neck injury in a crash.

Seatback Latches

(Full

Bench Seat)

I

K2106

The front seatback

folds

forward

to

let you access the rear

of

the cab. Your

seatback will move back and

forth

freely, unless you come to a sudden stop.

Then it will lock in place.

1-5

Seats

&

Safety

Belts

If you have a Four Door Model, your front seatback is designed not

to

fold

forward. Access

to

the rear of the cab is available by using the rear doors.

There’s one time the seatback may not fold without some help from you.

That’s

if

your vehicle is parked going down a fairly steep hill.

If

this happens,

push the seatback toward the rear as you

lift

this latch. Then the seatback

will

fold

forward. The latch must be down for the seat

to

work properly.

Seatback Latches (Bench Seat With Armrest)

K2547

The front seatback folds forward

to

let you access the rear of the cab.

If you have a Four Door

Model,

your front seatback is designed not

to

fold

forward. Access

to

the rear

of

the cab

is

available by using the rear doors.

To

fold a seatback forward, pull this lever up and fold the seatback forward.

To

return the seatback

to

the upright position, just push the seatback

rearward until it latches.

After returning the seatback

to

its upright position, pull the seatback forward

to

make sure it is locked.

1

CAUTION

If

the seatback isn’t locked,

it

could move forward in a sudden stop

\

or crash. That could cause injury

to

the person sitting there. Always

press rearward

on

the seatback

to

be sure

it

is locked.
