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.

Clearing A Flooded Engine (Using Fob With
Integrated Key)
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, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
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.
AUTOMATIC TRANSMISSION
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)
380 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 remove the key fob. Once the key fob is
removed, the shift lever is locked in the PARK
position, 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 ignition switch can be turned to the LOCK/
OFF position. The key fob can only be removed from the
ignition when the ignition is in the LOCK/OFF position,
and once removed the shift lever is locked in PARK.
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.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new

WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can result
in severe transmission damage. Refer to “Recre-
ational Towing” in “Starting And Operating” and
“Towing A Disabled Vehicle” in “What To Do In
Emergencies” for further information.
DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
and third gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the “AutoStick” mode
(refer to “AutoStick” in this section) to select a lower
gear. Under these conditions, using a lower gear will
improve performance and extend transmission life by
reducing excessive shifting and heat buildup.
5
STARTING AND OPERATING 387

SPORT
This mode alters the transmission’s automatic shift
schedule for sportier driving. Upshift speeds are in-
creased to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console. Refer to “Selec-Terrain” in “Starting And
Operating” for further information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. The Malfunction Indicator Light (MIL)may be illuminated. Limp Home Mode allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
388 STARTING AND OPERATING

NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing conditions are present:
•the shift lever is in the DRIVE position,
•vehicle speed is sufficiently high, and
•the driver is not heavily pressing the accelerator.
When to Use TOW Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, select TOW mode, using the rotary switch on the
center console. Selecting TOW mode will improve per-
formance and reduce the potential for transmission over-
heating or failure due to excessive shifting. Refer to
“Selec-Terrain” in “Starting And Operating” for further
information.
AUTOSTICK
AutoStickis a driver-interactive transmission feature
that offers manual gear shifting to provide you with more
control of the vehicle. AutoStickallows you to maximize
engine braking, eliminate undesirable upshifts and
downshifts, and improve overall vehicle performance.
