132 STARTING AND OPERATING

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
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
injured seriously or fatally. Don’t leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
(Continued)
WARNING! (Continued)
•Be sure to turn off the engine if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the gear selection lever or
by pressing the accelerator pedal. This may cause
excessive heat in the exhaust system, resulting in
overheating and vehicle fire, which may cause
serious or fatal injuries.
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.
134 STARTING AND OPERATING

Normal Starting
CAUTION!
The engine in your vehicle is designed for operation
down to 0°F (-18°C). Starting the engine below 0°F
(-18°C) creates a potential for scuffing or seizing of
internal components in this very high performance
engine. To prevent engine damage, do not start the
engine at temperatures below 0°F (-18°C).
NOTE:
•You must disarm the security system in order to start
the engine. For details, refer to “Security Alarm Sys-
tem” in Section 2 of this manual
•Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator
pedal. However, if the engine has not started within
three seconds, slightly depress the accelerator pedalwhile continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the OFF/LOCK
position, 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 gear selector in NEUTRAL
4. Insert the ignition key fully into the ignition switch
5. Turn the key to the ON/RUN position.

6. Press the red ENGINE START 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 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.

136 STARTING AND OPERATING

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 procedure carefully. See section 6 of
this manual for jump starting instructions.
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.If the engine shows no sign of starting after two 15 sec-
ond periods of cranking with the accelerator pedal held
to the floor, the NORMAL STARTING procedure should
be repeated.
After Starting
The idle speed will automatically decrease as the engine
warms up.
MANUAL TRANSMISSION
NOTE:The parking brake should be engaged and the
shift lever selector placed in 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 depressed to
the floor during each shift. As you release the clutch
pedal, lightly depress the accelerator pedal.

•Shifting gears during cold weather may require an
increased effort until the transmission lubricant is
warm. This is normal and not harmful to the transmis-
sion.
•Due to the high performance nature of your drivetrain,
a certain amount of noise from the transmission is
normal. This noise can be most noticeable when the
vehicle is idling in NEUTRAL with the clutch engaged
(clutch pedal released), but it may also be heard when
driving. The noise may also be more noticeable when
the transmission is warm. This noise is normal and is
not an indication of a problem with your clutch or
transmission.
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 duringcruise 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 transmis-
sion directly from FIRST gear to FOURTH gear
instead of from FIRST gear to SECOND gear. This is to
help you get the best possible fuel economy from your
vehicle. This occurs when engine coolant is higher than
106°F (41°C), and vehicle speed is greater than 12 mph
(19 km/h) but less than 20 mph (32 km/h), and engine
speed is less than 1,322 RPM, and the transmission is in
STARTING AND OPERATING 139

FIRST gear, and the accelerator is at 1/4 throttle or less.
The Skip Shift Indicator Light located in the tachometer
will turn Amber during these times.
When the indicator light turns amber, the shift mecha-
nism 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.WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have an accident.
CAUTION!
If you skip more than one gear while downshifting
or downshift at too high an engine speed, you could
damage the engine, transmission, or clutch.
