ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three positions, OFF, ACC, RUN.
To change the ignition switch positions without starting
the vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Press the ENGINE START/STOP button once tochange the ignition to the ACC position.
3. Press the ENGINE START/STOP button a second time to change the ignition to the RUN position.
4. Press the ENGINE START/STOP button a third time to return the ignition 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
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel in case the engine is flooded.
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.

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)
within the Stop/Start section. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understand-
ing 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 main-
tained upon return to an engine running condition.

STARTING AND OPERATING 395

Possible Reasons The Engine Does Not AUTO
STOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
In following situations the engine will not stop:
•Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• Battery temperature too warm or cold
• The vehicle is on a steep grade
• Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
• HVAC is set to full defrost mode at a high blower
speed •
Engine has not reached normal operating temperature
• Battery discharged
• The transmission is not in DRIVE
• Hood is open
• Vehicle is in 4LO transfer case mode
Other factors which can inhibit AutoStop include: fuel
level, accelerator pedal input, engine temp too high and
steering angle.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
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
396 STARTING AND OPERATING

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
The engine may then be restarted by moving the trans-
mission shift selector out of PARK (e.g. to DRIVE) or, in
some cases, only by a KEY START. The Electronic Vehicle
Information Center (EVIC) will display a SHIFT OUT OF

CAUTION!(Continued)
•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 401

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,
turn the engine OFF, and remove the key fob. When
the ignition is in the full OFF (key removal) posi-
tion, the transmission is locked in PARK, securing
the vehicle against unwanted movement.
• When leaving the vehicle, always remove the key
fob and lock your vehicle.
(Continued)
WARNING! (Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the transmission gear selector.
• Do not leave the key fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go ™ in the ACC or ON/RUN
mode. A child could operate power windows, other
controls, or move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
402 STARTING AND OPERATING

before the ignition switch can be turned to the full OFF
(key removal) position. The Key Fob can only be re-
moved from the ignition when the ignition is in the full
OFF position, and the transmission is locked in PARK
whenever the ignition switch is in the full 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). 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 speeds (refer to
Brake/Transmission Shift
Interlock System in this section). To shift past multiple
gear ranges at once (such as Park to Drive), simply rotate
the gear selector to the appropriate detent. Select the
DRIVE range for normal driving.
5
STARTING AND OPERATING 403

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).
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 gear selector has only PARK, RE-
VERSE, NEUTRAL, and DRIVE positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) switches (described later in this section). Pressing
the GEAR-/GEAR+ switches (on the steering wheel)
while in the DRIVE position will select the highest
available transmission gear, and will display that gear in
the instrument cluster as 1, 2, 3, etc.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
Electronic Transmission Gear Selector
404 STARTING AND OPERATING

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.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade. NOTE:
On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not in PARK. Make sure the transmission is
in PARK before leaving the vehicle.
