KEYS
Two different keys are· provided for the locks on your vehicle. The key code is
stamped on the "knock out" plug in each key head.
• Key with square head (letter "A" or "e") -for ignition lock only.
• Key with oval head (letter "8" or "0") ~ for all other locks.,
For vehicle security:
• Record the key code numbers; then knock the plugs out of the keys.
• Keep the key codes in a safe place (such as your wallet), NOT IN THE
VEHICLE.
If the original keys are lost, duplicates can
be made using the key codes. Contact
any
OM dealer or a locksmith.
If yO~i park in an attended lot, leave only your square-head ignition key.

recline of the saatbeck. The -lap belt is d .. ignad to spread the force of a collision over the strong hlp bone instead of across the abdomen. However, if the hips are
reclined, the lap bett may slide past the hips and ilpply restraint forceS directly to the abdominal region.
Front Seatback Latches
Vehicles with folding front seats have inertial seatback latches. The latches are
designed to prevent forward movement of the front seatback only during a sudden
slowing
of the vehicle. Normally, the seatback can be tilted forward without
unlatching, to get in
or out of the rear seat. But when the vehicle is ""nose down"
such as on a very steep hill, the inertial latch may keep the seat back from being
moved forward. If this happens, there is a latch release lever at the bottom, in
the center rear
of each front seatback. pun rearward slightly on the seat back while
pulling up on the seatback latch release lever .. This will release the latch and alJow
the seat back to be moved forward.
The latch release lever must.
be in the "down" position for the inertial latch to
work properly during a sudden slowing of the vehicle. Checkrtow and then to
see
if each seatback latch release lever moves up and down freely. If the lever does
not move freely, take the vehicle to your dealer for service. There is no convenient
owner test of the inertial seatback latch.
If you suspect the latch is not working,
ask the dealer to inspect
it.
Keep seat belt webbing and hardware clear of seat parts when you tilt folding seats
forward or rearward. This helps prevent damage to these belt systems.
Manual Window Controls
Crank type handles located in the door panels anow the side windows to be
manually raised or lowered.
Power Windows (Optional)
Power windows have an ignition interlock so the windows cannot be operated
unless the ignition switch is in the "run" position.
A master control for all windows
is provided at the driver's position. Individual
switches are provided under each window for passenger use.

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.

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.

Downloaded from www.Manualslib.com manuals search engine Engine Temperature Gage
This gage indicat~cCX?lant temperature which will vary with air temperature and
operating condition~, The ignition 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 Red Zone, see "Engine Cooling
System" on page 3-3.
Oil Pressure Gage
The oil pressure gage indicates the pn;ssure at which oil is being delivered 10 the various parts of the engine requiring lubrication. Pressures registered by the gage
I11.!lY vary according to outside air temperatures or weight of oil being used. Oil
pressure of a cold engine ~ing operated at a given speed will be somewhat higher
than when the engine is at normal operating temperature at the same speed .
. Prolonged high speed operation on a hot day at the given speed will result in somewhat lower oil pressure readings. Readings of 30 to 40 psi (205 to 275 kPa)
mny
be considered normal during moderate road speeds of 35 to 40 mph (55 to
60 km/h) \\lith the engine at proper operating temperature. Gage readings which
are
consistently high or Im\l under these conditions may indicate lubrication system Voltmeter
When the engine is operating, the voltmeter indicates the electrical system voltage.
During minimum electrical load, the pointer will read to the right of the center.
As the electrical load is increased,
or in stop-and-go driving, the pointer will rotate
to the left. A meter reading continuously in
the left or right red zone indicates
an electrical system
failure .. Cause of the failure should be determined and corrected~
Light Switch
The three position light switch controls the headlights, taillights, parking lights,
sidemarker 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 condition develops,
have your headlamp wiring checked immediately.
The headlight beam changer is located. in the
