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. Vehicles equipped with an automatic
transmission 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 dis-
charged 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 dan-
gerous if done improperly. Refer to “Jump Start-
ing” in “What To Do In Emergencies” for further
information.

262 STARTING AND OPERATING

CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that is
located on the driver side of the Integrated Power Module.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
MANUAL TRANSMISSION — IF EQUIPPED
Six-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.
5
STARTING AND OPERATING 263

Earlier upshifts during cruise conditions (relatively
steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired
acceleration rate.
NOTE:
•Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
3 mph (5 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete
stop, you may notice lighter shift efforts into REVERSE
with the ignition switch in the ON position (RUN
position for Keyless Enter-N-Go) as compared to the
LOCK position (OFF position for Keyless Enter-N-Go).
This is normal operation of the transmission reverse
inhibitor system.
•Due to the high performance nature of your drivetrain,
you may hear your transmission. This can be most
noticeable when the vehicle is idling in NEUTRAL withthe clutch engaged (clutch pedal released), but it may
also be heard when driving at low engine RPM. Also,
this may be more noticeable when the transmission is
warm. This is a normal condition and is not an indica-
tion of a problem with your clutch or transmission.
1–4 Skip Shift
There are times when you must shift the transmission
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 the engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at 1/4 throttle or less.
The “1–4 Skip Shift Indicator Message” will be displayed
during these times.
266 STARTING AND OPERATING

When the “1–4 Skip Shift Indicator Message” is dis-
played, the shift mechanism will only allow shifts from
first gear to fourth gear. After you shift the transmission
to fourth gear, you can press the clutch in and shift to
another forward gear.
Downshifting
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 a collision.
CAUTION!
•If you skip more than one gear while downshift-
ing or downshift at too high an engine speed, you
could damage the engine, transmission, or clutch.
•Do not downshift into first gear when the vehicle
is moving faster than 15 mph (24 km/h), as you
could damage the engine and/or clutch.
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the automatic transmission may occur if
the following precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.(Continued)
5
STARTING AND OPERATING 267

CAUTION! (Continued)
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
•Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing on
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or some-
thing. Only shift into gear when the engine is
idling normally and when your foot is firmly
pressing on the brake pedal.
(Continued)
268 STARTING AND OPERATING

WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and turn the engine OFF. When the ignition is in
the OFF position, the shift lever is locked in
PARK, securing the vehicle against unwanted
movement. Furthermore, you should never leave
unattended children inside a vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placingthe transmission in PARK. This system also locks the shift
lever in PARK whenever the ignition switch is in the OFF
position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock (BTSI) system that holds the shift lever in the
PARK position unless the brakes are applied. To move
the shift lever out of the PARK position, the ignition
switch must be turned to the ON/RUN position (engine
running or not) and the brake pedal must be pressed.
Five-Speed Automatic Transmission
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. You
must press the brake pedal to move the shift lever out of
the PARK position (refer to “Brake/Transmission Shift
Interlock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
