Downloaded from www.Manualslib.com manuals search engine cluster flashes to indicate proper
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) .

Always engage the parking brake
and place the automatic transmis­
sion selector lever in
"Park" posi- tion
when leaving your
car un­
attended. Also with automatic
transmissions, never park for pro­
longed periods with engine idling
and transmission in gear, especially
FLOOR CONTROLS
Braking System
The service brake system is de­
signed for braking performance
under a wide range of driving con­
ditions even when the vehicle
is
loaded to its full rated vehicle load.
NOTE: Operation of the brake
system warning light
is covered on
page 2-15 in the section on
"In­
strument Panel."
Power Brakes
• On cars with power brakes, if
power assist to the brakes
is in­
terrupted due to a stalled engine
or some malfunction, two or
more brake applications nor­
mally can be made using reserve
power.
• If the brake pedal is held down,
2-10
if your car is equipped with air
conditioning. This practice
is detri­
mental to the transmission, due
to
overheating.
the system
is designed to bring
the car 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 main­
tain steering control on slippery
surfaces.
• When reserve power is exhausted,
the vehicle can still be stopped
by applying greater force to the
pedal.

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 protection at -20o
P (-28°C) or
below to ensure protection against
corrosion
and · loss of coolant
from boiling even though freezing
temperatures are not expected.
• Add ethylene glycol base coolant
that meets
GM Specification
1899-M when coolant additions
are required because of coolant
loss
or to provide additional pro­
tection against freezing at tem­
peratures lower than -20oP
(-28°C), and in Canada to
-35°P (-37°C).
NOTE: Alcohol or methanol base
coolants or plain water are not
recommended for your vehicle at
any time.
Your vehicle, if equipped with
standard 4-cylinder engine, has
an aluminum cylinder block.
When adding anti-freeze, rust
inhibitors, or cleaners, make
certain they are safe for
use
with aluminum components.
Radiator Pressure Cap
The radiator cap, a 15 lb. pres­
sure type, must be installed tightly,
otherwise coolant may be lost and
damage
t6 engine may result from
overheating. Radiator pressure caps
should be checked periodically for
proper operation.
If replacement is
required specify AC.
Thermostat
The cooling system is protected
and controlled by a thermostat that
maintains a satisfactory engine
operating temperature. This
ther­
mostat is installed in the engine
coolant outlet and
is designed for
continuous use through both winter
and summer. When replacement
is
necessary, Delco parts are recom­
mended.
