The code number of each key is
stamped on the "knock out" plug
in the key head. Your Chevrolet
dealer removed these plugs and
placed them with the spare set of
keys in the special key envelope
that was given to you at time of
delivery.
For your protection:
• Record the numbers on the key
envelope and discard the key
plugs.
• Keep the key envelope in a safe
place such
as your wallet, Not In
The Car.
In the event the original keys are
lost, duplicates can be made by
your dealer or a locksmith using
the key code information.

their retractors. The comfort clip
can be adjusted when removing
belts,
so shoulder belt slack can
be taken up by retractor.
NOTE: Take care not to let the
"lap" portion of the belt twist while
it
is being rewound into the retrac­
tor. 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 mecha­
nism may prevent the belt from be­
ing withdrawn.
If a belt should
become jammed, you may be able to
release it by working the belt in and
out until the belt rewinds far enough
to unlock.
If lap belt portion remains
jammed, or
other parts of the re­
straint system do not operate prop­
erly take the vehicle to your dealer
for service.
Lap Belts, Rear Seat
• Seating positions next to side win­
dows have retractors which are
designed to automatically take up
excess
webbing. These belts
should be positioned, secured,
and released
as described above
under
"Front Seat Lap-Shoulder
Belt
Combination".

Belt Restraint Inspection
• Periodically inspect belts, buck­
les, latch plates, retractors, re­
minder systems, guide loops, clips,
and anchors for proper operation,
and also for damage that could
lessen the effectiveness of the re­
straint system.
• Keep sharp edges and damaging
objects away from belts and other
parts of restraint system.
• Replace belts if cut, weakened,
frayed,
or subjected to collision
loads.
• Check that anchor mounting
bolts are tight.
• Have questionable parts replaced.
• Keep belts clean and dry.
• Clean only with mild soap solu­
tion and lukewarm water.
• Do not bleach or dye belts since
this may severely weaken belts.

Since passenger cars are designed
and intended to be used primarily
as passenger conveyances, towing
a trailer will effect handling, dura­
bility
and economy. Maximum
safety and satisfaction depends
upon proper use of correct equip­
ment and avoiding overloads and
other abusive operation.
The maximum loaded trailer
weight which you can pull with
your car depends on what special
equipment has been installed on
your car. Chevrolet does not rec- ommend
towing any trailer
over
1,000 pounds gross trailer weight.
Information on trailer haul­
ing capabilities, special equipment
required, and optional equipment
offered by Chevrolet
is available
from your Chevrolet Dealer or by
writing Chevrolet Motor Division,
Detroit, Michigan 48202
(or in
Canada by writing to General
Motors of Canada Limited,
Owner
Relations Department, Oshawa,
Ontario LlJ 5Z6).
To assist in attaining good han­
dling of the car-trailer combination,
it
is important that the trailer
1-9
tongue load be maintained at ap­
proximately 10%
of the loaded
trailer weight. Tongue loads can
be adjusted by proper distribution
of the load in the trailer, and can
be checked
by weighing separately
the loaded trailer and then the
tongue.
When towing trailers, tires should
be inflated to the highest inflation
pressures shown on the placard
affixed
to the left front door. The
allowable passenger and cargo
load, also shown on the same pla­
card,
is reduced by an amount
eq ual to the trailer tongue load on
the trailer hitch.

operation of the front and rear turn
signal lamps.
If the indicator lamp
remains on and does not flash,
check for a defective lamp bulb.
If
the indicator fails to light when the
lever
is moved, check the fuse and
indicator bulb.
NOTE: For operation of hazard
flasher, see page 3-1, in
Section "In
Case of Emergency."
Horn
The horn on your car is actuated
by firmly pressing on the pad in the
center of the steering wheel.
As a good motorist,
~se of the
horn should be kept at a minimum.
However, acquaint yourself
as soon
as possible with this function of
your car, should it ever become
necessary to give a warning to a
pedestrian
or another motorist.
Power Steering
If the steering system power as­
sist fails due to some malfunction,
or because the engine has stalled,
the vehicle can still be steered.
However, much greater effort
is re­
quired, particularly in sharp turns.
Tilt Steering Wheel
The tilt steering wheel (optional
equipment) can be tilted up above
normal position to provide addi­
tional room for entrance and exit
2-9
as well as selected driving· posi­
tions below normal height. This
permits individual selection of the
most natural position for
all driv­
ing conditions.
On long trips the
steering wheel position can be
changed to minimize tension and
fatigue.
The tilt mechanism
is operated
by lifting up on the small control
lever on the left side of the steering
column just below the directional
signal, moving the steering wheel
to the selected position, and re­
leasing the lever.
Holding Car on an Upgrade
When stopped on an upgrade,
maintain your position by applying
the brakes. Never hold the car
in
place by accelerating engine with
transmission in gear. This could
cause damage by overheating
the
. transmission (automatic) or clutch
(manual) .

Downloaded from www.Manualslib.com manuals search engine Parking Brake
• To set parking brake, pull up
the handle located between the
seats.
• For maximum holding power,
depress regular brake pedal at
the same time.
• To release parking brake, de­
press the button in the handle
tip and push the handle down.
• As a reminder, the brake system warning
light
is designed to come
on whenever the parking brake
control
is not fully released, and
the ignition ·
is on.
• Never drive car with parking
brake set
as this may overheat
or otherwise damage rear brakes.
NOTE: "Riding the brake" by
resting your foot on the brake pedal
when not intending to brake can
cause abnormally high brake tem­
peratures, excessive lining wear and
possible damage to the brakes.
REMINDER:
Front disc brakes
have a built-in wear indicator that
is designed to make a high fre­
quency, squealing,
or cricket-like
warning sound when the linings are
2-11
worn where replacement 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 checks listed
in the Chevrolet maintenance sched­
ule folder.
Clutch Adjustment
Clutch adjustment should be
checked and adjusted periodically
as necessary to compensate for
clutch facing wear.
To check,
depress pedal by hand until resist­
ance
is felt. Free travel of pedal
should be approximately one inch;
if very little
or no free travel is
evident , clutch adjustment is re­
quired.

The red light will go on when
the ignition key
is in the "on" posi­
tion, but before the engine
is started.
After the engine starts, the light
should go out and remain out.
If
the light remains on when engine
is running, have your Authorized
Chevrolet Dealer locate and correct
the trouble
as soon as possible.
Temp. Pressure Indicator
Light
This indicator light is provided
in the instrument cluster to quickly
warn of an overheated engine
and/or extreme low oil pressure
or oil supply. This light will be on
when the ignition switch is turned
"ON" and should go out after the
engine
is started. Occasionally the
light may be seen to flicker momen­
tarily, but this will do no harm. Ex­
treme low oil pressure or oil supply
will prevent the electric fuel pump from
operating and under this con­
dition the engine will not run.
If the light comes on during ex­
treme driving conditions, such
as an
extended idle, turn off the air con­
ditioner (if used) and run the en­
gine slightly faster than idle speed
with the transmission in
neutral
gear. If the light does not go off
within a short period of time (1-2
minutes), then turn the engine off
until the cause of
the overheating is
corrected. Glance at the instrument
cluster frequently
as you drive to
see if this light is on.
Add Coolant Indicator Light
This indicator light is provided to
warn of a low coolant condition in
the radiator.
If coolant level is low
the yellow
"Add Coolant" warning
light will glow. Coolant level in the
coolant recovery tank, and radiator,
should be checked at the first oppor­
tunity.
If necessary add sufficient
2-15
coolant to both the radiator and
coolant recovery tank.
(See Service
and Maintenance, Section 5, for
proper procedure) .
If frequent
additions are required, see your
dealer for a complete cooling sys­
tem check.
Brake System Warning
Light
The service brake system is a dual
system designed so that one part will
provide some braking action in the
event of loss of hydraulic pressure
in the other part of the system.
If the
warning light labeled
"Brake" lo­
cated in the speedometer face comes
on and stays
on when the ignition is
on and after the brakes have been
firmly applied
it may indicate that
there
is a malfunction in one part of
the brake system.
• As a reminder, the light is de­
signed to come
on with the park­
ing brake applied and the igni­
tion on.

Downloaded from www.Manualslib.com manuals search engine • The light is also designed to come
on during engine starting to
verify that the bulb
is operating
properly.
• Have system repaired if light does
not come
on during check.
• This warning light is not a substi­
tute for the visual check of brake
fluid level required
as part of
normal maintenance.
If the light comes on:
• The parking brake control is not
fully released, or,
• The service brake system is par­
tially inoperative.
What to do:
1. Check that parking brake is re­
leased.
If it is . . .
2.
Pull off the road and stop, care­
fully-remembering that:
• Stopping distances may be
greater.
• Greater pedal effort may be re­
quired.
• Pedal travel may be greater. 3.
Try out brake operation by start­
ing and s,topping on road shoul­
der-then:
• If you judge such operation to
be safe, proceed cautiously at
a safe speed to nearest dealer
for repair.
• Or have car towed to dealer for
repair.
Continued operation of the car in this
condition
is dangerous.

dark roads since they provide ex­
cellent long range illumination. The
headlight beam indicator will be on
whenever the high beams or
"brights" are in use. The Headlight
Beam
Switch controls the headlight
beams (see Page
2-12).
Light Switch
The three position light switch
controls the headlights, taillights,
parking lights, side marker lights,
instrument lights and dome lights
as shown. The headlamp circuit
is protected by a circuit breaker in
the light switch.
An overload on
the breaker will cause the lamps to
"flicker" on and off. If this condi­
tion develops, have your headlamp
wiring checked immediately.

Engine Temperature Gauge
This optional gauge indicates
coolant temperature which will vary
with air temperature and operat­
ing conditions.
The ignition switch
must be on for accurate readings.
Hard driving
or prolonged idling in
very hot weather will cause the
pointer to move beyond the center
of the band. Should pointer move
to the line at the right end of the
band, stop engine or reduce speed
to permit engine to cool.
