LAP

BELTS

Your vehicle

is

equipped with lap belts

in

the

driver

and

front passenger seating

position(s).

It

is

recommended

that

while

the

vehicle

is

in motion , a

ll

occupants
remain seated and keep lap belts buckled
snugly

at

all times.

The

front

outboard

seating positions- have

retractors

which

are

designed

to

automatically take up

excess webbing.

• Adjust seat

to

your

satisfaction and sit

erect and well back in the seat.

• In a single motion, pull webbing across
lap far enough to permit inserting metal
latch plate

end

of

lap belt into the

buckle, until a snap

is

heard.

If

webbing

7

is

not pulled

out

far enough

to

reach

the

buckle, let

the belt

rewind into

the

retractor

to

release lock mechanism, so

be

lt can be pulled

out

to

the

proper

length.

• Position lap belt across lap as

LOW

ON

HIPS

as possible. To reduce

the

risk

of

sliding

und

er the belt during an accident,

adjust to a

SNUG

FIT

by pulling belt

firmly across lap in direction

of

retractor

so it can take up slack.

NOTE: Take care

not

to

let

the

lap belt

twist while

it

is

being rewound into

the

retractor. The bulk

of

the

twisted belt

may cause

the

retractor

to

jam so it will

not

rewind further, while

at

the

same time

the

retractor's locking mechanism may

prevent

the

belt from being withdrawn. If

a belt should become jammed,

you

may be

able

to

release it by working

the

belt in

or

out

until

the

belt rewinds far enough

to

unlock. If lap belt remains jammed

or

other

parts

of

the restraint system do

not

operate properly take

the

vehicle

to

your

dealer for service.

CAUTION

A snug fit

and

a low lap belt

position are essential

to

lessen

the

chance

of

injury in

the

event

of

an

accident, because this spreads

the

Lap Be

lt (Fro

nt

Seating Position)

force

exerted

by

the

lap

belt

in

a

collision over

the

strong hip bone

structure

rather

than

acrosS

the soft

abdominal area.

To

help lessen

the

chance

of

injury in

the

event

of

an

accident: Never use

the

same

belt

for

more

than

one

person

at

a

time; avoid wearing belts in a

twisted

condition;

do

not

allow bel

ts

or

hardware

to

become

dam

aged

by

being pinched between

the

seat

structural

(metallic) members

or

in

the

door.

Inboard seating

pos1t1on, front

dual

passenger seat (if so

equ

ipped) should be

positioned and secured as above, and

adjusted to a

SNUG

FIT

by

pulling on

the end

of

the

belt extending from the ad-

justable

htch

plate.

•

To

lengthen

the

lap belts

at

these

seating positions, place adjustable latch

plate

at

right angle

to

the

belt

webbing

and

puU

on

latch plate; belt should

then

sliJe easily through the

adjustment

feature .

•

To

unfasten scat belts, depress push

button

in center

of

buckle.

8

• When

no

longer in use, front

outboard

lap belts can be stowed

by

allowing

them to rewind

into

their retractors.

LAP

BELT

INSPECTION

• Periodically inspect belts, buckles, latch
plates, retractors, and anchors for damage
that

could lessen

the

effectiveness

of

the

restraint system.

• Keep sharp edges and damaging objects
away from

be

lts and

other

parts

of

the

restraint system .

• Replace belts

if

cut,

weakened, frayed,

or

subjected to collision loads.

• Check

that

the

anchor

mounting

bolts

are tight.

• Have questionable parts replaced.

e Keep belts clean and dry.

• Clean only with mild soap solution and
lukewarm water.

•

Do

not

bleach

or

dye

belts since this

may severely weaken

them.

CHILD

RESTRAINT

Children in vehicles should be restrained

to lessen

the

risk

of

injury

in

accidents,

or

sudden stops.

In

using

any

infant

or

child

restraint system, read and comply with all

installation and usage instructions.

All unused lap belts

near

the child

should be stowed properly

to

help prevent

them from striking

the

child in the event

of

an accident. Lap belts

without

storage
provisions should have buckles latched and
belts adjusted

to

remove slack.

If

a child

is

traveling in a

equipped

with

an appropriate

child restraint system,

the

precautions should be taken:

vehicle not

infant

or

following

I. Infants unable to

sit

up

by themselves

should

be

restrained

by

placing them

in
a covered padded bassinet placed
crossways in

the

vehicle (widthwise)

on

the seat.

The

bassinet should

be

securely

restrained with

the

regular vehicle lap

belts.

2. Children able

to

sit up

by

themselves

should be placed

on

a seat and lap

belted. Never allow a child

to

stand

or

kneel

on

any

seat

or

elsewhere in the

vehicle,

once

it

is underway.

TRAILER HAULING

Towing a trailer will

affect

handling,

durability and

economy.

Maximum safe ty

and satisfaction depends

upon

prop

er

use

of

correct

equipment

and avoiding overloads

and

other

abusive

operation.

The

maximum

loaded trailer weight

which you can pull

with

your

vehicle

depends

on

what

special

equipment

has

been installed. GMC does

not

recommend

towing any trailer

OVER

GROSS

TRAILER

WEIGHT unless

the

vehicle

HAS

THE

REQUIRED

EQUIPMENT.

To

assist

in

attaining good handling

of

the

Vehicle Trailer Combination,

it

is

important

that

the

trailer tongue load be

maintained

at

approximately I 0%

of

the

loaded trailer weight.

•Ton

gue loads can

be

adjusted

by

proper

distribution

of

the load

in

the

trailer, and can be checked

by

weighing separately

the

load

ed

trailer and

then

the

tongue.

The allowable passenger and cargo load

(GVW)

of

this vehicle

is

reduced by

an

amount

equal to

octane

number.

If

you

plan

to

operate

your

vehicle

outside

the

continenta

of

the

United

States

or

Canada,

there

is

a possibility

that
the best fuels available are so low in
anti-knock quality

that

excessive knocking
and serious engine damage may result from
their use.

To

obtain

information on

the

quality

of

fuels available in the countries

in

which

you

plan

to

travel write to GMC

EXHAUST

GAS

CAUTION

(CARBON

MONOXIDE)

Avoid inhaling exhaust gases because they contain carbon monoxide, which by

itself

is

colorless and odorless. Carbon monoxide

is

a dangerous

gas

that

can

cause unconsciousness and

is

potentially lethal.

If,

at

any time, you suspect

that

exhaust fumes are entering

the

vehicle

from any source have

the

cause determined and corrected as soon

as

possible.

If

you must drive before

the

cause

is

corrected, drive only with ALL windows

FULLY open and heating

or

cooling system adjusted for maximum ventilation

(see below).

The

best

protection against carbon monoxide entry into

the

vehicle body

is

a
properly maintained engine exhaust system , body and body ventilation system.
It

is

recommended

that

the

exhaust system and body

be

inspected by a

competent mechanic:

• Each time the vehicle

is

raised for lubrication

or

oil change.

• Whenever a change is noticed

in

the

sound, alignment, or appearance of

the

exhaust system.

• Whenever

the

exhaust system, underbody

or

rear

of

the

vehicle

is

damaged.

See

your Maintenance Schedule folder for inspection procedure.

To

allow proper operation

of

the

vehicle's ventilation system, keep

front

inlet

grille clear

of

snow, leaves, or

other

obstructions

at

all times .

or

roof vent must remain open for a period while

driving,

or

electrical wiring

or

other cable connections

to

a trailer must pass

through

the

seal between

them

and

the

body,

the

following precautions should

be

observed.

• Close all windows.

• Adjust heating

or

cooling system

to

force outside air into

the

vehicle as

described

in

Step 1

or

2 above

but

with fan set

at

high speed.

• Air vents

in

or

und•

the

instrument panel should

be

fully open.

It

is important

that

the inside engine cover

be

properly seated

to

prevent

possible

leakage

of

exhaust fumes into

the

vehicle through this opening.

The kick-up panel

at

the

r&a"

of the floor (see illustration) contains holes

which may

be

utilized

to

facilitate access

to

the interior for installation

of

certain interior equipment (i.e., access for wiring, plumbing, etc.) The holes

should

be

plugged

and

sealed

to

avoid possible exhaust

gas

(carbon monoxide)

intrusion into

the

interior

of

the

vehicle.

Whenever operating

the

optional motor-generator it

is

essential

the

left-rear

window (if so equipped)

of

the

vehicle

be

kept dosed

to

prevent possible

entry

of

motor-generator exhaust gases into vehicle. Inspect

the

motor-generator

exhaust system

at

vehicle lubrication intervals

or

when a change

is

noticed in

the

sound, alignment,

or

appearance of

the

exhaust system or if

it

is

damaged.

Do

not

run motor-generator

in

a confined area, such as a garage.

NOTE: Particular care should

be

taken

to

prevent

the

possibility

of

carbon

monoxide exposure when

the

vehicle is modified for recreational

or

other

usage.

Additionally, some recreational vehicle appliances (such

as

lights, refrigerators,

stoves, heaten)

may generate carbon monoxide and should

be

used only if

there

is

adequate

ventilation.

that

the

vehicle will

not

slow down

at

the

usual rate,

and

may pull

Parking Brake Control

• On

your

vehicle,

if

power assist

to

the

brakes is interrupted due

to

a stalled

engine

or

some malfunction, two

or
more brake applications can normally be
made using reserve power.

•

If

the

brake pedal

is

held down,

the

system

is

designed

to

bring

the

vehicle

to a full

stop

on

reserve power.

However,

the

reserve power

is

partially

depleted each

time the brake pedal is

applied and released. Do

not

pump

brakes when brake power assist has been

interrupted, except when necessary in

order

to

maintain steering control

on

slippery su

rf

aces.

• When reserve power is exhausted,

the
vehicle can still be stopped by applying
great

er

force

to

the pedal.

SELF

nd

apply brakes firmly in

each direction.

• See

your

dealer if normal pedal travel is

not

res

tor

ed,

or

if there

is

a rapid

increase in pedal travel, which could be

a sign

of

othe

your

dealer also

if

adjustment

of

the parking

brake

is

required.

NOTE: "Riding The Brake"

by

resting

your

foot

on

the brake pedal when

not
intending to brake can cause abnorm ally
high brake temperatures, excessive lining

wear and possib

le

damage

to

brakes in

addition

to

wasting gasoline.

REMINDER:

Front

disc brakes have a

built-in wear indicator

th

at is designed

to

make a high frequency , squealing,

or

cricket-like warning sound when

the

linings

are worn to where rep

la

ceme

nt

is required.

The sound will

occur

intermittently

or

continuously when wheels are rolling,

but

will disappear when the brake pedal

is

applied firmly. See also

the

various brake

PARKING

BRAKE

• To set parking brake, pull up

the

handle

located

on

the floor against the l

eft

wall, below the instrument panel.

•

For

increased holding power, first depress
regular brake pedal with the right foot,
and hold

it

while setting

the

parking

brake with left hand.

•

To

release parking brake push

the

handle

down.

•

As

a reminder, the

"PA

RK BRAKE"

reminder light

is

designed

to

come

on

whenever

the

parking brake

contro

l is

not

fully released, and the ignition is

on.

• Never drive vehicle with parking brake
set

as

this may overheat

or

otherwise

damage rear brakes.

The

amount

of

force required

to

apply

parking brake can be adjusted

by

turning a

tension adjustment knob located

at

the

upper end

of

the

lever. This also adjusts

the degree

of

brake application.

The

greater

the force required

at

the lever

the

greater

the degree

of

brake application.

NOTE:

The

parking brake

shou

ld

be

set

first whenever the driver's seat is l

eft

unattended.

If

the vehic le is parked

on

a grade and·

the transmission is placed in

"PARK"
before the parking brake is set, the weight
of

the vehicle

may

exert

so much force

on

the parking pawl in the transmission

that

the transmission selector lever

cannot

later be pulled

out

of

"PARK."

To

prevent this, the parking brake should be

applied

BEFORE

moving

the

transmission

selector lever

to

"PARK."

When preparing

to move the vehicle,

the

shift indicator

should be moved

out

of

the

"PARK"
position

BEFORE

releasing the parking

brake.

It

is

good driving practice

to

set
the parking brake first, and release the
transmission from

"

PARK"

first

at

all

times, even

on

the level.

If

"torque

lock",

as this condition

is

called, does

occur

, it

may be necessary

to

have

another

vehicle

nudge this vehicle

up

hill, to take some

of

th

e pressure

off

the transmission while

the

driver pulls

on

the transmission selec

tor

OIL

PRESSURE

GAUGE

This gauge registers engine oil pressure.

Speedometer and

Gauge

Clusters

The consistency

of

the

oil in a cool

engine will cause a high reading when

the
engine is first started. As the engine
warms, the pressure will recede to normal.

With the engine warmed up

to

normal

operating temperature,_ minimum pre

ssure

at

idle sho uld be slightly above

the

"L"

graduation (8 PSI).

At

normal operating

speeds, minimum pressure should be

20

between the second and middle graduations

(35 PSI). Should the pressure drop below
these

mtn1mums

,

stop

the

engine

immediately and check

the

cause

of

the
low oil pressure. This could be the result
of

a dangerously low oil level in the
crankcase. Driving the vehicle with low oil
pressure can cause extensive engine damage.

23

Fuel Tank and Battery Switches

BATTERY

BOOST

SWITCH

The

GMC

Dual Battery System provides

power from

two

batteries

to

the vehicle's

12-volt

electrical

system either

in

combination

or

singularly. The components

used to provide charging

and/or

switching

are conventional, except for a diode

assembly with which

both

batteries will

receive charging current whenever

th

e

vehicle is running. The diode assembly has

separate

outputs

to

the two batteries and

provides isolation between

the

batteries and

their associated circuits whenever

the

engine

is

not

running.

The main battery (or automotive battery)

supplies power

to

the chassis circuit; i.e.,
engine, external lights, etc. The auxiliary
battery powers

the

vehicle's internal area;

i.e., internal lights, etc.

The

battery

switch should be left in the

"BAT

NORMAL" position, except when

additional power is needed

for

either

battery circuit.

If

this

is

desired, change

switch to

"BAT BOOST" position. After

use,

it

is recommended

that

switch be

returned

to

the

"BAT NORMAL" position.

NOTE:

If

the

battery

boost switch is left

in

the "BAT BOOST" position for

extended periods this can result in both

batteries being discharged.

Automotive Heating Syste

ms

Controls

The auxiliary battery will recharge itself

while the vehicle's engine

is

running.

CIGAR-CIGARETTE LIGHTER

Push

the

lighter in all the way

to

operate. When it

is

heated sufficiently

to

use, it is designed

to

"snap"

back to
normal position with noticeable sound.
Avoid holding the lighter in by hand while
it

is

heating.

For added safety,

the

cigar-cigarette

lighter has a heat-sensitive terminal which is

designed to melt and break the circuit

if

the lighter becomes overheated.

HEATING SYSTEM

(WITHOUT

AUTOMOTIVE

AIR CONDITIONER)

The heating system controls are located

on the instrument panel

to

the right

of
the steering column. There are three
separate controls;

"FAN"

lever

to

control

speed

of

blower operation; "RECIRC,"

"COLD,"

"HOT"

lever to control

temperature

of

air,

"OFF,"

"VENT

,"

"HEATER,"

"DEF"

lever to control

direction

of

air flow. The

"FAN

" lever
works vertically and the other two levers
work horizontally. The three levers may be
placed in any combined position

to

deliver

the

climate conditions most desirable

at

any given time.

•

''FAN"-

The fan switch has four

positions;

"LO"

and three blower speeds

ranging

to

"HI."

Fan will operate

whenever the key is in the

"RUN"

or

24

"ACCESSORY" position. In order to

operate the fan

in

the

"HI"

position the

engine must be running.

e

"OFF,"

"VENT,"

"HEATER,"

"DEF"-With

the lever in the

"OFF"

position the system is

off

except for the

blower. With

the

lever in the "VENT"
position 100% outside air enters the
driver's compartment. The air enters

through the dash mounted

out

lets and
through the heater outlets. Temperature
of

incoming air may

be

controlled by

moving the

"RECIRC," "COLD,"

"HOT"
(temperature) lever to desires position.
Any one

of

the blower speeds may be

selected.
With

the

lever in

the

"HEATER"

position, air

wil

l flow through the heater
floor distributor outlet (with slight flow
of

air

to

the defroster outlet).

For
maximum heat, move temperature lever
to

"HOT"

position and

"FAN"

switch

lever

to

"HI"

position. Heating system

output

can be varied by moving

temperature lever and

"FAN"

lever

to

different positions.

With lever in the

"DEF"

position,

the
system operates the same as in the
"HEATER"

position except most

of

the

air flow will

be

through

the

defroster

outlets

at

the windshield.

e "RECIRC," "COLD,"

"HOT"-This

lever,

used

in

conjunction with the system

selector

lever

("OFF,"

"VENT,"

"HEATER,"

"DEF")

and the

"FAN"

switch lever, will control the temperature

of

the

output

air being distributed.

• Clear windshield, rear window, outside
mirror, and all side windows

of

ice and

snow before driving vehicle.

e Operate blower on

"HI"

for a few
seconds before moving the vehicle, to
clear the air intake

of

snow

to

further

reduce the possibility

of

fogging on

inside

of

windshield.
