442 STARTING AND OPERATING

Automatic Transmission
Start the engine with the transmission in PARK position.
Apply the brake before shifting into any driving range.
NOTE:
•This vehicle is equipped with a transmission shift
interlocking system. The brake pedal must be pressed
to shift out of PARK.
•If equipped with an 8 speed transmission starting the
vehicle in NEUTRAL is not possible unless the Manual
Park Release has been activated. For the Manual Park
Release operation refer to Manual Park Release in
“WHAT TO DO IN EMERGENCIES.”
Tip Start Feature
Do notpress the accelerator. Cycle the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.
Keyless Enter-N-Go™
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the Remote
Start/Keyless Enter-N-Go™ Key Fob
is in the passenger compartment.
Normal Starting
Using The ENGINE START/STOP Button
1. The transmission must be in PARK or NEUTRAL.

4. If you wish to stop the cranking of the engine prior to
the engine starting, push the button again.
NOTE:Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
To Turn Off The Engine Using ENGINE
START/STOP Button
1. Place the shift lever/gear selector in PARK, then press
and release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3.If the shift lever/gear selector is not in PARK, the
ENGINE START/STOP button must be held for two
seconds or three short presses in a row with the vehicle
speed above 5 mph (8 km/h) before the engine will shut
off. The ignition switch position will remain in the ACC
position until the shift lever/gear selector is in PARK
and the button is pressed twice to the OFF position. If
the shift lever/gear selector is not in PARK and the
ENGINE START/STOP button is pressed once, the
EVIC/DID will display a “Vehicle Not In Park” message
and the engine will remain running. Never leave a
vehicle out of the PARK position, or it could roll.
NOTE:If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.
450 STARTING AND OPERATING

STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal will automatically
re-start the vehicle.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START
NOT READY until you drive forward with a vehicle
speed greater than 5 mph (8 km/h). At that time, the
system will go into STOP/START READY and if all other
conditions are met, can go into an STOP/START AUTO
STOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
1.The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
Electronic Vehicle Information Center (EVIC)/ Driver
Information Display (DID) within the Stop/Start section.
Refer to “Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in Drive and
the brake pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the stop/start telltale will illuminate
indicating you are in an Autostop. While in an Autostop,
the Climate Controls system may automatically adjust
airflow to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running condition.

STARTING AND OPERATING 453

To Start The Engine While In Autostop Mode
While in DRIVE the engine will start when the brake
pedal is released or the throttle pedal is depressed. The
transmission will automatically reengage upon engine
restart. During this transition the brakes will hold the
vehicle to avoid undesired vehicle movement.
Conditions that will cause the engine to start automati-
cally while in Autostop mode.
The Engine Will Start Automatically When:
•The transmission selector is moved from DRIVE to
REVERSE or NEUTRAL
•To maintain cabin temperature near the HVAC settings
•HVAC is set to full defrost mode
•Autostop time exceeds 5 minutes
•Battery voltage drops too low
•Low brake vacuum (e.g. after several brake pedal
applications)
•STOP/START OFF switch is pressed
•4WD system is put into 4LO mode
•The emissions system requires it
•A STOP/START system error occurs
Conditions that force an automatic shift to PARK while
in Autostop mode.
The Engine Will Not Start Automatically and the Trans-
mission will be placed in PARK if:
•The driver door is open and brake pedal released
•The driver door is open and the driver seat belt is
unbuckled
•The engine hood has been opened
•A STOP/START system error occurs

AUTOMATIC TRANSMISSION
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.
WARNING!
•It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.

STARTING AND OPERATING 459

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 ignition switch can be turned to the LOCK/
OFF (key removal) position. The Key Fob can only be
removed from the ignition when the ignition is in the
LOCK/OFF position, and the transmission is locked in
PARK whenever the ignition switch is in the LOCK/OFF
position.
NOTE:If a malfunction occurs, the system will trap the
Key Fob in the ignition switch to warn you that this
safety feature is inoperable. The engine can be started
and stopped but the Key Fob cannot be removed until
you obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift
the transmission out of PARK, the ignition switch must
be turned to the ON/RUN position (engine running, for
vehicles with eight-speed transmission) and the brake
pedal must be pressed.
In 8-speed vehicles, 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.
Eight-Speed Automatic Transmission — If
Equipped
The transmission is controlled using a rotary electronic
gear selector located on the instrument panel. The trans-
mission gear range (PRND) is displayed both above the
gear selector and in the Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID). To
select a gear range, simply rotate the gear selector. You
must press the brake pedal to shift the transmission out
of PARK, or to shift from NEUTRAL into DRIVE or
REVERSE, when the vehicle is stopped or moving at low
5
STARTING AND OPERATING 461

REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking
brake and shift the transmission into PARK if you must
leave the vehicle.
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 a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
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 all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
466 STARTING AND OPERATING

2. Shift the transmission into PARK, if possible. If not,
shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine
turns OFF.
4. Wait approximately 30 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.
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.
Electronic Range Select (ERS) Operation —
Eight-Speed Transmission
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the
transmission is in DRIVE. For example, if you shift the
transmission into 4 (fourth gear), the transmission will
not shift above fourth gear (except to prevent engine
overspeed), but will shift through the lower gears nor-
mally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically, shift-
ing between all available gears. Tapping the GEAR-
switch (on the steering wheel) will activate ERS mode,
display the current gear in the instrument cluster, and
maintain that gear as the top available gear. Once in ERS
mode, tapping the GEAR- or GEAR+ switch will change
the top available gear.
