Downloaded from www.Manualslib.com manuals search engine NOTICE: Use only trailer hitches which permit normal operation of the Energy Absorbing Bumper System. if so equipped. For example. a rigid fore and .iUt connection between the bumper and any other part.of. the car may increase .damage in the event of II collision.
TRAILER TOWING TIPS
Getting Started
Before entering traffic with a frailer that has electric brakes, start the car and
trailer moving and apply the trailer brakes
by hand to be sure the trailer brakes
are working and the trailer electrical system
is connected .
. Engine Cooling
: long \.Jphill Grades
When going up long grades, you, can reduce the chance 'of engine overheating by
turning
off the air conditioner, if so equipped.
Transaxle
,See the method for checking the transaxle fluid le ve l. in "Service and
,.;.Maintenance," Section 5 of this manual .
Parking
You should not park cars with trailers on a grade (hill). However, if you must
park on a grade, these steps must be followed:
1. Apply the regular brakes.
2. Have someone place wheel' chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load .
4; Apply Ihe parking brake.
S. Shift Ihe transaxle 10 ··P"(Park).
If the car is parked on a grade. don't shift the transaxle 10 "P"(Park) until the
trailer wheels
are chocked and the parkinghrake, is set~ If you do, the weight of . the car and trailer may put so much force on the parking pawl in the transaxle
.
that it may be hard to shift oul of "P"(Park).
When starting , after being parked ' on a grade:
(; Apply the regular brakes and hold.
2 .
Stan th e engine in ··P"(Park) .
-3. Shift into gear and release the parking brake.
4. Release the regular brakes and drive until the chock s are free.
5. Apply the regular brakes and have your helper remove the chocks.

Downloaded from www.Manualslib.com manuals search engine CAUTION: Driving thr~gh water deep enough to wet the brakes may cause the brakes not to work as well. As 8 result the vehicle will not slow down at the usual
rate ; and it may pull to the right or left. After checking to the rear for other vehicle., apply the brakes lightly to check whether this has happened. To dry them quickly, lightly apply the brakes. At the-same time, k .. p a safe forward speed, with plenty of clear space ahead, to the rear, and to the side •. 00 this until the brakes return to normal.
The brake system warning light is covered in the "Instrument Panel" section.
Power Brakes
• If optional power assis t is lost because of a stalled engine or other reasons .
the brakes can normally still be applied with power assist at leas t two times
u sing reserv e power.
• Th e system is designed to bring the vehicle to a full stop on reserve power if the brake pedal is applied once and held down . However . the reserve power
is partly used up each time the brake pedal is applied and rele ased. Do not
pump the brakes when ,brake power assist has been lost, except when needed
to maintain steering control on slippery surfaces.
• Without power assist, the vehicle can still be stopped by pushing much harder
o n the brake pedal. However, the stopping distance may be longer. even
though the brakes themselves remain fully operational.
Self-Adjusting Brakes
• The brakes on this vehicle (exc,ept for the parking brake) are self-adjusting.
They have been design ed so
that periodic brake adjustment is not required.
• The drum brakes adjust themselves when the brakes are firml y applied while
the vehicle is moving backwards.
• The disc brakes adjust themselve s each time the brakes are used.
• If the brak e pedal goes down farther than nonnal. it may be due to a lack
of adjustment. To find out if this is the case, drive backward and forward
a few times , applying the brakes firmly when going each way.
• See yo ur dealer if pedal height does not return to normal, or if there is a rapid
increase in pedal travel, which could be a sign of other brake trouble .
• Also see your dealer if the parking brake needs adjustment' .
NOTICE: "Riding the brake" by resting your foot on the brake pedal when not intending to brake can cause overheated brakes. This can waar out the brake linings faster and damage the brakas thamselvas, 85 well 8S waste fuel.
DIMMER SWITCH
The dimmer switch that controls the headlight high/lo w beam is built into the
turn signal control. See the "Steering Column Controls" Section 2 of this manual.
PARKING BRAKE
• To set the parking brake, fully depress the foot pedal at the far left side.
• For better holding power, first press down the regular brake pedal with your
right foot. Then hold it while setting the parking brake with your lefl foo[.
•
To release the parking brake, pull the "Brake Release" handle located at the
lower left of the instrument panel.
• To help remind you. the brake system warning light is designed to come on if the parking brake control is not fully released and the ignition key is on.

Downloaded from www.Manualslib.com manuals search engine • Never drive-the vehicle _with the parking brake set as this -may overheat the
reaf brakes reducing their effectiveness and causing excessive wear or damage,
DISC BRAKE WEAR INDICATORS
Front disc brakes have built-in wear indicators that are designed to make a
high-pitched
squealing or cricket-like warning sound when the brake linings are
worn 10 where -new linings are needed. The sound will come and go, or be heard
all the time
when the wheels are rolling, and when the brake pedal is pu~hed down
firmly . Expensive damage can result
if linings are not replaced when needed.
See also the brake checks listed in the Maintenance Schedule folder.
CLUTCH .PEDAL
On models equiPPed with a manual transaxle, a clutch pedal is used to engage
or disengage the clutch, thereby connecting
or disconnecting the engine from the
transaxle and drive1ine to the front wheels. -When the pedal is fully extended the
clutch
is engaged, driving the transaxle arid the front wheels.
INSTRUMENT PANEL P.ND CONTROLS
INSTRUMENTS
The instruments, gages and indicator lights conveniently grouped in the
instrument cluster are des igned to
tell you at a glance many important things about
_the perfonnance of your vehicle _, _ The following information will enable you to
more quickly -understand and properly it';:rerpretthese instruments.

Fuel Gage
The fuel gagewiH register the_APPROXIMATE fuel level in the tank, when the
ignition
is in the RUN position.
When the gage registers
EMPTY, some fuel is still available as a reserve. When
the gage registers
FULL. some additional" fuel can"still be added to the tank. The
following conditiqns may be considered normal:
• Gas station _pump may shut off before fuel gage indicates FULL. •
•
Amount of gasoline required for fill-up may not exactly correspond to gage.
• Needle may not move away from FULL until some time after fill·up.
• Needle may !Dove during turns. stops and-accelerations.
When the ignition switch
is turned to the OFF position, the needle will not

ENGINE COOLING SYSTEM
Your cooling system may temporarily overheat during severe operating
conditions, such as:
• climbing a long hilLon a hot qay,
•
stopping after high speed driving,
• idling for long periods' in' traffic, or
• towing a trailer.
If theUTEMP" light comes on (or if you have a coolant temperature gage, the
needle goes
into the warning zone) and your air conditioner is on, tum it off. If
the. 'ITEMP" light (gage) comes on while you are stopped in traffic, move the
transaxle shift lever to UN" (Neutral). If the "TBMP" light doesn't go off (or the
gage
needle doesn't start to drop) within a minute or two:

Downloaded from www.Manualslib.com manuals search engine 3. Stop the engine. Open the radiator drain valve to drain the coolant. (Drainage
may be speeded by removing the drain plugs in the block.)
4. Close the drain valve (install block drain plugs, if removed). Add water until
the system is filled and run the engine until the upper radiator hose is hot again.
5. Repeat steps 3 and 4 several times until the drained liquid is nearly colorless.
6. Drain the system and then close the radiator drain valve tightly. (Install block
drain plugs, if removed.)
7. Disconnect all hoses from the coolant recovery tank. Remove the tank and
pour out any fluid. Scrub and clean the inside of the tank with soap and water.
Flush it well with clean water,
then drain it. Reinstall the tank and hoses.
8. Add enough water and ethylene glycol antifreeze (meeting GM Specification
1899-M)to provide the required cooling, freezing, and corrosion protection. Use a solution that is at least 50 percent antifreeze, but no more than 70
percent antifreeze. Fill the radiator to the base of the filler neck and fill the
coolant recovery
tank to the "Full Hot" mark. Put the recovery tank cap back
on.
9. Run the engine, with the radiator cap removed, until the upper radiator hose
is hot.
10. With the engine idling, add coolant to the radiator until it reaches the bottom
of the filler neck. Install the radiator cap, making sure the arrows on the cap line up with the overflow. tube.
It is the owner's responsibility to:
• Maintain cooling system freeze protection at _37°C (_34°F) to ensure
protection against corrosion and loss of coolant from boiling. (A SO/50
mixture of water and ethylene glycol antifreeze will provide freeze protection
to ~ 37°C ore -34°P.) You should do this even if you don't expect freezing
temperatures.
• Add ethylene glycol base antifreeze that meets GM Specification 1899-M
when antifreeze
hasto be added because of coolant loss or for more protection
' against freezing at temperatures lower than _37°C (-·J4°P).
NOTICE: Do not use alcohol or methanol-base antifreeze. or plain water alone. in your vehicle at any time. They will boil at a lower pOint than that at which the hot light indicator (or temperature gage) works. and they do not provide proper protection against corrosion.
Radiator Pressure Cap
The radiator cap, a 105 kPa(15 psi) pressure type, must be installed tightly,
otherwise coolant may be lost and damage to engine may result from overheating.
Radiator pressure caps should be checked periodically for proper operation.
If
replacement is required, an AC cap is recommended.
Thermostat
The engine coolant temperature is controlled by a thermostat. It stops coolant flow
through the radiator until a preset temperature is reached. This thermostat is
installed in
the engine coolant outlet on the engine block. The same thermostat is used in both winter and summer. When a replacement is needed, AC~Delco parts
are recommended.

Downloaded from www.Manualslib.com manuals search engine FUSES AND CIRCUIT BREAKERS
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers; and fusible thermal links in the wiring itself. This greatly reduces
the hazard of electrically caused fires in the automobile.
The fuse junction box is located under the right side of the instrument panel.
The
headlight wiring is protected by a circuit breaker in the light switch. An electrical overload will cause the lights to go on an,d off, or in some cases to remain off. If this happens , have your headlight wiring checked right away. Besides a fuse, the windshield wiper motor is also protected by a circuit breaker. If the motor overheats, due to overloading caused by heavy snow, etc., the wiper ·will remain stopped until the motor cools. Be sure to have the cause of the over· loading corrected. Circuit breakers for power windows and power door locks are located on the bulkhead in the engine
compartment.
