WARNING!(Continued)
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.
•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 OFF mode, the trans-
mission is locked in PARK, securing the vehicle
against unwanted movement.

WARNING!(Continued)
•When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the Key Fob
from the vehicle, and lock the vehicle.
•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 in the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
404 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 placingthe 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.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “ECO” switch in the center stack of the
instrument panel and an amber light will indicate the
ECO mode is engaged.

STARTING AND OPERATING 405

This system relies on four microphones embedded in the
headliner to detect the exhaust drone and prompt an
onboard frequency generator to create counteracting
sound waves through the audio system’s speakers and
sub-woofer. This helps keep the vehicle quiet at highway
speeds.
Eight–Speed Automatic 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 return-
ing to the center position after each gear is selected. The
transmission gear (PRND) 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 lowspeeds (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). 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.
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 will5

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.
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.
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. Check by trying to move the
shift lever out of PARK with the brake pedal
released. Make sure the transmission is in PARK
before leaving the vehicle.
•It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If

deep may cause damage to the front fascia and
ground effects.
Flowing/Rising Water
WARNING!
Do not drive on, or cross, a road or a path where
water is flowing and/or rising (as in storm run-off).
Flowing water can wear away the road or path’s
surface and cause your vehicle to sink into deeper
water. Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cautions
and Warnings before doing so.
