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 liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
• 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.
(Continued)
WARNING! (Continued)
•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
START/STOP Button)
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:
1. Press and hold the brake pedal.
2. Press the accelerator pedal all the way to the floor and hold it.
3. Press and release the ENGINE START/STOP button once.

STARTING AND OPERATING 395

When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
• The transmission will launch (from a stop) in second
gear.
• The torque converter clutch may engage at lower
engine speeds and remain on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
NOTE: ECO mode is only available in AUTO mode.Eight–Speed Automatic Transmission
Your vehicle is equipped with a state of the art, fuel
efficient eight-speed transmission. The electronic shift
lever in this vehicle does not slide like a conventional
shifter. Instead, the shift lever is spring loaded and moves
forward and rearward, always returning to the center
position after each gear is selected. The transmission gear
(PRND) is displayed both on the shift lever and in the
Electronic Vehicle Information Center (EVIC). 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 REVERSE when
the vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). To shift past multiple gear ranges at once (such as
PARK to DRIVE), move the lever past the first (or second)
detent. Select the DRIVE range for normal driving.

STARTING AND OPERATING 399

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 shift lever provides PARK, REVERSE,
NEUTRAL, DRIVE and SPORT shift positions. Once in
the DRIVE range, tapping the shift lever rearward will
toggle between SPORT mode and DRIVE mode. You do
not need to press the shift lever button when toggling
between DRIVE and SPORT modes. Manual shifts can
be made using the shift paddles mounted on the steering
wheel. Pressing the shift paddles (-/+) while in theDRIVE or SPORT position will manually select the trans-
mission gear, and will display the current gear in the
instrument cluster. Refer to
Paddle Shift Modein this
section for further information.

position. A child could operate power windows,
other controls, or move the vehicle.
• Before moving the shift lever out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the shift lever could
result.
CAUTION!
• DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
