against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in
fresh air with the blower setting in high. This will ensureadequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold weather. To clear
the windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the Recirculation
mode without A/C for long periods, as fogging may
occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In Winter months make sure the air intake
is clear of ice, slush and snow.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct any other occupant to buckle their seat
belt.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the key fob in
or near the vehicle (or in a location accessible to
children), and do not leave a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
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.
Normal Starting
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.
202 STARTING AND OPERATING

NOTE:
•You must disarm the security system in order to start
the engine. Refer to “Security Alarm System” in
“Things To Know Before Starting Your Vehicle” for
further information.
• Normal starting of either a cold or a warm engine does
not require pumping or pressing the accelerator pedal.
However, if the engine has not started within three
seconds, slightly press the accelerator pedal while
continuing to crank. If the engine fails to start within
15 seconds, wait five seconds, then repeat the “Normal
Starting” procedure.
To Start The Engine:
1. Fully apply the parking brake.
2. Press the clutch pedal to the floor.
NOTE: The engine will not start unless the clutch pedal
is pressed to the floor. 3. Place the shift lever in NEUTRAL.
4. Press the red ENGINE START/STOP button located
on the instrument panel. Release the button when the
engine starts.

If Engine Fails To Start
CAUTION!
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.
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
(Continued)
WARNING! (Continued)
•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 proce-
dure carefully. Refer to “Jump Starting” in “What
To Do In Emergencies” for further information.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the ENGINE
START button is released. If this occurs, continue crank-
ing up to 15 seconds with the accelerator pedal pushed
all the way to the floor. Release the accelerator pedal and
the ENGINE START button once the engine is running
smoothly.
204 STARTING AND OPERATING

If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” procedure should
be repeated.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
MANUAL TRANSMISSION
NOTE:The parking brake should be engaged and the
shift lever placed into REVERSE before leaving the
vehicle, especially when parked on an incline.
Your vehicle is equipped with a high torque capacity dual
disc clutch. The clutch pedal must be fully pressed to the
floor during each shift. As you release the clutch pedal,
lightly press the accelerator pedal.
CAUTION!
• 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, as this will cause
abnormal wear on the clutch.
• Failure to press the clutch pedal fully to the floor
may cause increased shift efforts, and may result in
damage to the clutch and transmission.
• Do not rest your hand on the shift lever while
driving, as this may result in transmission damage.
• Do not attempt to shift the transmission if the rear
wheels are spinning due to loss of traction. Dam-
age to the transmission may occur.
Be sure the transmission is in first gear when moving
forward from a standing position.

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 Indicator Light
There are times when you must shift the trans-
mission directly from first gear into fourth gear
instead of from first gear into second gear. This
is to help you get the best possible fuel
economy from your vehicle. This occurs when engine coolant is higher than 107°F (42°C), and vehicle speed is
greater than 16 mph (26 km/h) but less than 18 mph
(29 km/h), and engine speed is less than 1,650 RPM, and
the transmission is in first gear, and the accelerator is at
20% throttle or less. The “Skip Shift Indicator Light”
located in the tachometer will illuminate during these
times.
When the “Skip Shift Indicator Light” illuminates, the
shift mechanism will only allow shifts from first gear to
fourth gear. After you shift the transmission into 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.
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
208 STARTING AND OPERATING

CAUTION!
If you skip more than one gear while downshifting
or downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.
STREET/RACE MODE – IF EQUIPPED
This vehicle is equipped with an electronic controlled
damping system. This system allows for a street suspen-
sion damping setting or a firmer race suspension damp-
ing setting. When in street mode the system automati-
cally shifts the suspension dampers to the firmer Race
damping setting during some hard acceleration andbraking situations. The system also reduces body roll and
pitch in many driving situations including acceleration
and braking. There are two modes of operation:
NOTE:
With the ignition in the ON/RUN position, the
suspension damping system will be in the last mode the
system was in when the vehicle was turned off. The
driver can select either Street or Race damping mode at
any time.
• Street Mode — This mode will give a sporty, but
comfortable ride. Within this mode, the suspension
will adapt to the vehicle inputs, including vehicle
speed, braking and acceleration. This mode is driver
selectable when the vehicle is placed in STREET mode
(press the “STREET” button on the Instrument Panel).
This mode will set suspension for maximum perfor-
mance handling and is intended for a smoother ride on
the various types of pavement and road conditions
while still providing damping levels appropriate ex-
treme capabilities.

STARTING AND OPERATING 209

•Race Mode — This mode is driver selectable when the
vehicle is placed in RACE mode (press the “RACE”
button on the Instrument Panel). This mode is for track
use only and will supply maximum grip to the tires.
NOTE: The RACE setting will provide a firmer ride.
• When RACE mode is enabled, a Shock symbol with
“RACE” next to it will light up in the instrument
cluster.
LAUNCH MODE – IF EQUIPPED
This system maximizes acceleration traction for straight
line racing.
1. Bring vehicle to complete stop on a level track surface with the engine running.
2. Set the steering wheel for straight ahead driving.
3. Fully depress the clutch and select the first gear position. 4. Press and release the “LAUNCH” Button (Located on
the steering wheel controls).
5. Press the accelerator pedal to the floor.
