Keyless Enter-N-Go™ Functions — With Driver ’s
Foot OFF The Brake Pedal/Clutch Pedal (In PARK
Or NEUTRAL Position)
The Keyless Enter-N-Go™ feature operates similar to an
ignition switch. It has three positions, OFF, ACC and
RUN. To change the ignition switch positions without
starting the vehicle and use the accessories follow these
steps starting with the ignition switch in the OFF posi-
tion:
1. Press the ENGINE START/STOP button once to
change the ignition switch to the ACC position,
2. Press the ENGINE START/STOP button a second time
to change the ignition switch to the RUN position,
3. Press the ENGINE START/STOP button a third time
to return the ignition switch to the OFF position.
Extreme Cold Weather (Below –20°F Or−29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
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.

352 STARTING AND OPERATING

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission 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 a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
Clearing A Flooded Engine (Using ENGINE

Clearing A Flooded Engine (Using ENGINE
START/STOP Button) — Manual Transmission
Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather#proce-
dures, it may be flooded. To clear any excess fuel, press
and hold the clutch pedal, push the accelerator pedal all
the way to the floor and hold it, then press and hold the
ENGINE START/STOP button for no more than 15
seconds. Release the accelerator pedal and the clutch
pedal, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
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 must be plugged in at least one
hour to have an adequate warming effect on the engine.
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 near the air box.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
354 STARTING AND OPERATING

CAUTION!
Always make sure the vehicle comes to a complete
stop before shifting into REVERSE. Failure to do so
may result in transmission damage.
You must always use first gear (or REVERSE) when
starting from a standing position.
Recommended Shift Speeds
To utilize your manual transmission efficiently for fuel
economy, it should be upshifted as listed in recom-
mended shift speed chart.
MANUAL TRANSMISSION RECOMMENDED SHIFT SPEEDS
Axle Ratio1-44-55-6
3.90mph203748
(km/h)(32)(59)(77)
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.
5
STARTING AND OPERATING 357

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 ignition
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
with the 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 transmis-
sion is warm. This is a normal condition and is not an
indication of a problem with your clutch or transmis-
sion.
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 at¼throttle or less.
After you shift the transmission to fourth gear, you can
press the clutch in and shift to another forward gear.
358 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
•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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placing
the transmission in PARK. This system also locks the
transmission 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 system (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the engine must be running and the brake
pedal must be pressed.
The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.

STARTING AND OPERATING 361

Eight-Speed Automatic Transmission — If
Equipped
The transmission gear range (PRNDM) is displayed both
on the shift lever and in the Driver Information Display
(DID).
To select a gear range, press the lock button on the shift
lever and move the lever rearward or forward. You must
also press the brake pedal to shift the transmission out of
PARK, or to shift from NEUTRAL into DRIVE or RE-
VERSE when the vehicle is stopped or moving at low
speeds (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). Select the DRIVE range for normal
driving.The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Automatic Transmission Shifter
362 STARTING AND OPERATING

Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission shift lever has PARK, REVERSE, NEU-
TRAL, DRIVE, and MANUAL (Autostick®) shift posi-
tions. Manual shifts can be made using the Autostick®
shift control (refer to “AutoStick®” in this section for
further information). Toggling the shift lever forward (-)
or rearward (+) while in the MANUAL (AutoStick®)
position (beside the DRIVE position) will manually select
the transmission gear, and will display the current gear in
the instrument cluster as M1, M2, M3, etc.
NOTE:If the shift lever cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed for-
ward) it is probably in the MANUAL (AutoStick®, +/-)
position (beside the DRIVE position). In MANUAL
(AutoStick®) mode, the transmission gear is displayed in
the instrument cluster (as M1, M2, M3, etc.). Move the
shift lever to the right (into the DRIVE [D] position) for
access to PARK, REVERSE, and NEUTRAL.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
