Your car is designed to operate
on unleaded fuel of approximately
91 research octane number.
If you plan to operate your car
outside the Continental limits of
the United
States or Canada, there
is a possibility that the best fuels
available in some countries are so
low in octane rating that excessive
knocking and serious engine
dam­
age may result from their use. Also ,
if leaded fuels are used in vehicles
designed for unleaded fuels, it may result
in the deactivation of the
catalytic converter, if the vehicle
is
so equipped, and possibly other
related problems.
The use of leaded
fuel in a vehicle designed
for un­
leaded fuel will require different
maintenance intervals.
To obtain in­
formation on the octane rating and
availability of non-leaded fuels
available in the countries in which
you plan to travel, and a mainte­
nance schedule to be used when
operating on leaded fuel, write to
Chevrolet Motor Division,

you plan to travel.
It is recommended that you not
operate your car in any country not
having fuels meeting the require­
ments of your car's engine

Depress accelerator pedal and
hold to floor while starting until en­
gine
is cleared of excess fuel and is
running smoothly. Never "pump"
the accelerator pedal.
Warm-Up
Always let the engine idle for 20
to 30 seconds after starting and
drive at moderate speeds for sev­
eral miles, especially during cold
weather.
Driving with the Chevrolet Automatic Transmissions
The Turbo Hydra-Matic is a
completely automatic transmission
that replaces the standard clutch
and transmission.
After starting the engine with the
floor selector lever in N (Neutral)
or
P (Park) position select the
range desired (see table) and de­
press the accelerator.
A gradual start with a steady in­
crease in accelerator pressure will
result in best possible fuel economy.
Rapid acceleration for fast starts
will result in greater fuel consump­
tion.
Automatic transmission shift
quadrants of all GM cars continue
the uniform sequence of selector
positions. This particularly benefits
multicar families and those who oc­
casionally drive other cars.
Shift in­
dicators are arranged with
"Park"
position at one end, followed in se­
quence by
"Reverse", "Neutral"
and the forward driving ranges.
All automatic transmissions are
equipped with a starter safety switch
designed to permit starting the en­
gine only when the transmission
is
in the "Park" or "Neutral" position.
For additional engine braking ef-
2-4
fect, as sometimes needed in moun­
tainous driving, place the transmis­
. sion in low range.

The shift speeds chart indicates
the speeds at which each upshift of
the transmission should be
per­
formed to produce the best com­
promise between vehicle perform­
anceand fuel economy.
Turn Signals and Lane
Change Feature
The tum signal lever is located on
the left side of the steering column
iIllmediately under the steering
wheel. The lever
is moved upward
to signal a right turn and downward
to signal a left tum. Lamps on the
front and rear of the car transmit
this signal to other motorists and
pedestrians. The ignition switch
must be in the
"ON" position in
order for the tum signals to be
operational. This feature prevents
battery drain if the lever
is left in
an
"ON" position when your car is
not in use. In
a normal turning situation such
as turning a comer, the tum signal
is cancelled automatically after the
tum
is completed. However, in
some driving maneuvers such
as
changing lanes on an expressway,
the steering wheel
is not turned back
sufficiently after completing the
tum to automatically cancel the
2-8
tum signal. For convenience in such
maneuvers, the driver can flash the
tum signals
by moving the tum
signal lever part way (to the first
stop) and holding it there . The
lever returns
tq the neutral or can­
celed position when the driver re­
leases his hold on the lever.

Downloaded from www.Manualslib.com manuals search engine Generator Indicator Light
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 Gas Cap-The fuel tank filler cap
has a
two-step removal and in­
stallation procedure plus a pres­
sure-vacuum safety relief valve. It
is equipped with a double set of
locking tangs. To remove:
• Rotate cap one-half tum counter­
clockwise to clear the first set of
tangs from the slots inside the
filler neck. This will allow any
residual pressure to escape.
• Pull the cap outward and rotate
one-quarter
tum counterclock­
wise to clear second set of tangs
and remove the cap.
• To install, reverse this procedure.
NOTE: If this cap requires a re­
placement, only a cap with these
same features should be used.
Fail­
ure to use the correct cap can result
in a serious malfunction of the
sys­
tem. Correct replacement caps may
be obtained from your authorized
Chevrolet dealer.
ENGINE ITEMS
Engine Oil and Filter
Recommendations'
• Use only SE engine oil.
• Change oil each 6 months or
7,500 miles, whichever occurs
first,
except under the following
conditions:
*
-driving in dusty conditions
-trailer pulling
-extensive idling
-short-trip operation at
freez­
ing temperatures (engine not
thoroughly warmed-up) .
*Under these conditions, change oil
each 3 months
or 3,000 miles,
whichever occurs first.
• Operation in dust storms may
require an immediate oil change.
• Replace the oil filter at the first
oil change, and every second oil
change thereafter. AC oil filters
5-2
provide excellent engine pro­
tection.
See your Chevrolet dealer for
ad­
vice on the frequency of oil and
filter changes under unusual driving
conditions.
The above recommendations
ap­
ply to the first change as well as
subsequent oil changes. The oil
change interval for your Chevrolet
engine
is based on the use of SE
oils and quality oil filters.
Oil
change intervals longer than those
listed above will seriously reduce
engine life and may affect
Chevro­
let obligation under the provisions
of the
New Vehicle Warranty.
NOTE: Non-detergent and other
low quality oils are specifically not
recommended.
Only the use of SE
engine oils and proper oil and filter
change intervals assure you of
con­
tinued proper lubrication of your
Chevrolet engine.
