Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check wheel nuts for tightness, and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected or fuel, power steering fluid, trans-
mission fluid or brake fluid leaks are suspected, the cause
should be located and corrected immediately.

4. Oil Pressure Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on during starting, have the system checked by
an authorized dealer.
If the light comes on and remains on while driving, stop
the vehicle and shut off the engine. DO NOT OPERATE
THE VEHICLE UNTIL THE CAUSE IS CORRECTED.
The light does not show the quantity of oil in the engine.
This can be determined using the procedure shown in
Section 7.
5. Low Fuel Light
When the fuel level drops to 2 gallons, the fuel
symbol will light and a single chime will sound.6. Speedometer
Indicates vehicle speed.
7. Airbag Light
The light comes on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light does not
come on during starting, stays on, or comes on
while driving, have the system checked by an authorized
dealer.
8. Turn Signal Indicators
The arrows will flash in unison with the exterior
turn signal, when using the turn signal lever.

vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver 's responsibility tomaintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more tire pressures is low. The
Tire Pressure Monitoring Telltale Lamp will flash on and
off for 60 seconds when a system fault is detected. The
flash cycle will repeat every ten minutes or until the fault
condition is removed and reset.

Distance To Empty (DTE)
Shows the estimated distance that can be travelled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles estimated
driving distance, the DTE display will change to a text
display of9LOW FUEL9. This display will continue until
the vehicle runs out of fuel. Adding a significant amount
of fuel to the vehicle will turn off the9LOW FUEL9text
and a new DTE value will be displayed, based on the
current values in the DTE calculation and the current fuel
tank level.
Elapsed Time
Shows the total elapsed time of travel since the last reset
when the ignition switch is in the ACC position. Elapsed
time will increment when the ignition switch is in the ON
or START position.

Manual Transaxle
Before starting the engine fully apply the parking brake,
press the clutch pedal to the floor and place the gear
selector in NEUTRAL.
NOTE:The engine will not start unless the clutch pedal
is pressed to the floor.
NOTE:If key won't turn and steering wheel is locked,
rotate the wheel in either direction to relieve pressure on
the locking mechanism and then turn the key.
Normal Starting
Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator pedal.
Simply turn the ignition switch to the ªSTART'º position
and release when the engine starts. If the engine fails to
start within 15 seconds, turn the ignition switch to the
ªOFFº position, wait 10 to 15 seconds, then repeat the
normal starting procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.
If the vehicle has a discharged battery, booster cables
may be used to obtain a start from another vehicle.
This type of start can be dangerous if done improp-
erly, so follow the procedure carefully. See section 6
of this manual for jump starting instructions.
Extremely Cold Weather (below220ÉF or229ÉC)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Over inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed either on the
face of the driver's door or on the driver's side ªBº pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
