Gauges
Tachometer
This gauge shows engine speed in revolutions-
per-minute (RPM) times 1,000. Avoid excessive
engine speeds in any part of the red warning
zone, particularly when driving downhill or in
lower gears.
Coolant Temperature Gauge
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temperatures when driving in hot weather, up
mountain grades, or in heavy stop and go
traffic. If the red LED light turns on, stop the vehicle and
turn off the engine until the cause is corrected.
Oil Temperature Gauge
This gauge shows the oil temperature. The
gauge pointer will likely show higher tempera-
tures when driving in hot weather, up moun-
tain grades, or in heavy stop and go traffic. If
the red LED light turns on, stop the vehicle and turn off
the engine until the cause is corrected.
Oil Pressure Gauge
This gauge shows engine oil pressure when the
engine is running. The pressure will vary with
engine speed, oil viscosity, and engine tem-
perature. Oil pressures will be higher as the
engine is warming up. The normal operating pressure is
between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, turn off the engine until
the cause is corrected.
80 UNDERSTANDING YOUR INSTRUMENT PANEL

This gauge does not indicate the amount of oil in the
engine. The engine oil level must be checked under the
hood. Check the level often during severe usage.
Fuel Gauge
This gauge shows the amount of fuel in the gas
tank. The reaction time of the gauge has been
slowed to avoid needle fluctuation during pe-
riods of high G force cornering.
Voltage Gauge
This gauge shows the electrical system voltage.
The normal operating voltage is from 12 to 14
volts with the engine running. If the pointer
remains at either the high or low ends of the
scale, the electrical system should be serviced.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
Press and release the Time button to display the time.
Press and release the button a second time to turn off the
time display.

shows that the Air Conditioning compressor is on. Con-
ditioned air is now directed through the outlets selected.
Pushing the button a second time turns the compressor
OFF.
Slight changes in engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects.
Rear Window Defroster
Press the button once to turn on the Rear Window
Defroster and a second time to turn it off. A light
above the button shows that the Rear Defroster is On.NOTE:The defroster turns off automatically after 15
minutes of operation. Each later activation will allow 71¤2
minutes of operation.
CAUTION!
To avoid damaging the electrical conductors, do not
use scrapers, sharp instruments, or abrasive window
cleaners on the interior surface of the rear window.
Labels can be peeled off by soaking with warm
water.

Operating Tips
When operating the system during the winter months,
make sure the air intake, at the right side of the hood, is
free of ice, slush, snow or other obstructions such as
leaves. Leaves collected in the air-intake plenum may
reduce air flow and plug the plenum water drains.
The blower air will heat faster in cold weather if you use
only the low blower speeds for the first ten minutes of
vehicle operation.
During engine warm-up in cold weather, use the Defrost
mode to direct any cold air away from the occupants.

STARTING PROCEDURES
CAUTION!
Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
Fully apply the parking brake, press the clutch pedal to
the floor, and place the gear selector in NEUTRAL before
starting the engine.NOTE:The engine will not start unless the clutch pedal
is pressed to the floor.
Normal Startingof either a cold or a warm engine does
not require pumping or depressing the accelerator pedal.
To start the vehicle, turn the key to the ON position and
press the red ENGINE START button located on the
instrument panel and release when the engine starts. If

the engine has not started within 3 seconds, slightly
depress the accelerator pedal while continuing to crank.
If the engine fails to start within 10 seconds, turn the key
to the ªOFFº position, wait 5 seconds, then repeat the
normal starting procedure.If Engine Fails to Start
NOTE:The Remote Keyless Entry Transmitter MUST be
used to unlock the vehicle and disarm the alarm system.
In the event of a lost or defective Remote Keyless
Transmitter, the security system can be momentarily
disarmed to allow the vehicle to be started.
See the paragraph on the Vehicle Theft Security System in
Section 2 of this manual
98 STARTING AND OPERATING

WARNING!
Do not attempt to push or tow your vehicle to get it
started. 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 a booster battery or the battery in
another vehicle. This type of start can be dangerous
if done improperly, so follow this procedure care-
fully. See section 6 of this manual for jump starting
instructions.
If the engine fails to start after you have followed the
ªNORMAL STARTINGº procedure, it may be flooded.
Push the accelerator pedal all the way to the floor and
hold it there while cranking the engine. This should clear
any excess fuel in case the engine is flooded.NOTE:To prevent damage to the starter, do not crank
the engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the start
button is released. If this occurs, continue cranking with
the accelerator pedal pushed all the way to the floor.
Release the accelerator pedal and the start button once
the engine is running smoothly.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the ªNORMAL STARTINGº procedure
should be repeated.

After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
TRANSMISSION SHIFTING
NOTE:The parking brake should be engaged and the
gear selector placed in REVERSE before leaving the
vehicle, especially on an incline.
Fully depress the clutch pedal before you shift gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.Be sure the transmission is in FIRST gear, (not THIRD),
when starting from a standing position. Damage to the
clutch can result from starting in THIRD.
For most city driving you will find it easier to use only
the lower gears. For steady highway driving with light
accelerations, 6th gear is recommended.
Never drive with your foot resting on the clutch pedal, or
try to hold the vehicle on a hill with the clutch pedal
partially engaged. This will cause abnormal wear on the
clutch.
Never shift into REVERSE until the vehicle has come to a
complete stop.
NOTE:During cold weather, until the transmission
lubricant has warmed, you may have difficulty shifting.
This is normal and not harmful to the transmission.
100 STARTING AND OPERATING

Recommended Shift Speeds
To use your manual transmission for fuel economy it
should be upshifted as listed below. Shift at the vehicle
speeds listed for acceleration. Earlier upshifts during
cruise conditions (relatively steady speeds) will result in
increased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS
1-2 2-3 3-4 4-5 5-6
MPH 15 25 40 45 50
(km/h) (24) (40) (64) (72) (80)
Higher upshift speeds may be used to obtain a desired
acceleration rate.
Skip Shift Light
There are times when you must shift directly from First to
Fourth gear instead of from First to Second. An amber
(LED) arrow on the instrument cluster will light up
during these times. This is to help you get the best
possible fuel economy.
The shift arrow will light up when engine coolant is
higher than 106ÉF (41ÉC), vehicle speed is greater than 12
MPH and less than 20 MPH, engine speed is less than
1322 RPM, you are in 1st gear and you are at 1/4 throttle
or less.
When the arrow is lit, the shift mechanism will only
allow shifts from First to Fourth gears. After you shift to
Fourth gear, you can press the clutch in and shift to
another forward gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.
