YOUR

CHEVROLET

TRUCK

...

Chevrolet

wants

your

truck

to

operate

efficiently

...

to do

the

job

which

it

is designed to do

and

at

the

same

time

provide

greater

satisfaction.

This

manual

provides

the

information

for

the

proper

operation

and

general

maintenance

of

your

Chevrolet

Truck.

Other

information

has

been

in-

cluded

to

familiarize

the

operator

with

additional

features

of

the

vehicle.

To

obtain

maximum

efficiency

from

your

truck,

regular

attention

to vehicle

maintenance

is im-

portant.

Your

Chevrolet

Dealer

has

the

trained

personnel

and

specialized

equipment

to

properly

service

your

vehicle.

Have

him

inspect

your

truck

and

perform

any

maintenance

or

adjustments

required.

All

information

contained

in

this

Owner's

and

Driv

.

er's

Manual

is

based

on

the

latest

product

information

available

at

the

time

of

publication

approval.

The

right

is

reserved

to

make

changes

at

any

time

without

notice.

The

First

Few

Hundred

Miles

of

Driving

During

the

first few

hundred

miles of

driving

you

can,

by

observing

a few simple precautions,

add

to

the

future

performance

and

economy of

your

vehicle.

It

is

recommended

whenever

possible,

that

your

speed

during

the

first

500

miles

be

confined to

a

maximum

of

60

M.P.H.,

but

do

not

drive

for

extended

periods

at

anyone

constant

speed,

either

fast

or

slow.

During

this

period

, avoid full

throttle

starts

and,

if

possible,

abrupt

stops.

Gentle

brak-

ing

during

the

first few

hundred

miles of

operation

will

result

in

longer

brake

life

and

better

future

performance. Avoid

hard

stops especially

during

the

first

200

miles of

operation

since

brake

misuse

during

this

period

could

destroy

much

future

brake

efficiency.

Always

drive

at

moderate

speeds

until

the

engine

has

completely

warmed

up.

EMERGENCY STARTING

· . . with Manual Transmission

If

your

truck

is

equipped

with

a

manual

3~speed

or

4-speed transmission,

it

can

be

started

in

an

emergency

by

pushing.

When

being

pushed

to

start

the

engine,

turn

off all

unnecessary

electrical

loads,

turn

ignition

to

"ON",

depress

the

clutch

pedal

and

place

the

shift

lever

in

high

gear.

Re-

lease

the

clutch

pedal

when

speed

reaches

10

to

15

miles

per

hour.

Never

tow

the

truck

to

start.

...

with Automatic Transmission

The

engine

cannot

be

started

by

pushing

the

truck.

To

start

the

engine

when

the

battery

is

discharged,

use

an

auxiliary

battery

.or

energizer

with

jumper

cables.

Be

sure

to

observe

correct

polarity

(positive

terminal

to

positive

terminal

and

negative

terminal

to

negative

terminal)

when

connecting

the

auxiliary

battery

to

prevent

possible

damage

to

the

electrical system.

ROCKING

If

it

becomes

necessary

to

rock

the

truck

to

free

it

from

sand,

mud

or

snow,

move

the

selector

lever

from

"D"

to

"R"

(automatic

TOWING

(All

Except

Four

Wheel

Drive

Trucks)

Normally

your

truck

may

be

towed

with

.all

four

wheels

on

the

ground

for distances

up

to 50

miles

at

speeds of less

than

35

mph.

However,

the

drive

wheels

must

be

raised

off

the

ground

or

the

drive

shaft

disconnected

when

the

transmission

is

not

operating

properly

or

when

a

speed

of 35

mph

or

distance of

50

miles

will

be

exceeded.

CAUTION: For

towing,

the

transmission

should

be

in

neutral

and

the

engine

ignition

should

be

"off".

CAUTION:

If

vehicle

is

towed

on

its front

wheels

only,

the

steering

wheel

must

be

secured

with

the

wheels

in a

straight

ahead

position.

TOWING

(Four

Wheel

Drive

Trucks)

It

is

recommended

that

the

truck

be

towed

with

the

front

wheels

off

the

ground.

The

truck

can

be

towed,

however,

with

the

rear

wheels

off

the

ground

if

there

is

damage

in

the

rear

wheel

area

In

this

event,

the

transmission

selector

lever

should

be

placed

in

the

"N"

(neutral)

position

and

the

front

drive

disengaged.

Towing

speeds

should

not

exceed

35

mph

for distances

up

to

50

miles.

If

truck

is

towed

on

its

front

wheels,

the

steering

wheel

should

be

secured

to

keep

the

front

wheels

in

a

straight-ahead

position.

When

towing

the

vehicle

at

slow speeds (ap-

prox.

20

mph),

for

a

very

short

distance only,

the

transmission

must

be

in

neutral

and

the

transfer

case MUST

be

in

"TWO WHEEL HIGH."

When

towing

the

vehicle

at

faster

speeds for

greater

distances,

the

following

steps

MUST

be

taken:

•

If

front

wheels

are

on

the

road, disconnect

the

front

drive

shaft.

•

If

rear

wheels

are

on

the

road, disconnect

the

rear

drive

shaft.

•

•

POSITRACTION

AND

NO

SPIN

REAR

AXLE

The

above axles, optional

at

extra

cost,

provide

additional

traction

on

snow, ice,

mud,

sand,

and

gravel

,

particularly

when

one

rear

wheel

is

on

a

surfac

e providing

poor

traction.

During

normal

driving

and

cornering,

these

units

function as a

standard

differential.

When

one

wheel

encounters

a

slippery

surface,

however,

the

driving

force

to

the

rear

is

directed

to

the

·

wheel

having

the

better

traction.

CAUTION:

Never

run

the

engine

with

one

drive

wheel

off

the

ground,

since

the

vehicle

may

drive

through

the

wheel

remaining

on

the

ground.

Care

should

be

taken

to

avoid

sudden

accelerations

when

both

drive

wheels

are

on

a

slippery

surface.

A

heavy

throttle

may

cause

both

rear

wheels

to

spin.

This could

allow

the

rear

end

of

the

vehicle to

slide

sideways

on

a

crowned

road

or

when

in a turn.

NOTE

:

On

%

-ton

trucks,

when

starting

with

one

wheel

on

an

excessively

slippery

surface,

slight

application

of

the

parking

brake

(approximately

one-third

on)

may

be

necessary

to

help

energize

the

differential to

gain

maximum

traction.

Release

brake

when

traction is

regained.
