BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is applied. If you cannot move
the gearshift lever out of P (Park) when the ignition is on and the brake
pedal applied, it is possible that a fuse has blown or the vehicle’s brake
lamps are not operating properly. Refer toFuses and relaysin the
Roadside Emergencieschapter.
If the fuse is not blown and the brakelamps are working properly, you
will need to have your vehicle towed to an authorized dealer.
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Switch the ignition to off,
and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
AUTOMATIC TRANSMISSION OPERATION
Understanding the gearshift positions of the 6–speed automatic
transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.

P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
•Press the brake pedal
•Move the gearshift lever into the
desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and
securely latch it in P (Park)
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Switch the ignition off and
remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Drive)

Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
The system defaults toenabledevery time the ignition is switched on.
Press the control to disable or enable the system
Keep the sensors (located on the front and rear bumper/fascia)
free from snow, ice and large accumulations of dirt (do not clean
the sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the sensing system.
If your vehicle sustains damage to the front or rear
bumper/fascia, leaving it misaligned or bent, the sensing zone may
be altered causing inaccurate measurement of obstacles or false
alarms.
REARVIEW CAMERA SYSTEM (IF EQUIPPED)
The rearview camera system,
located on the trunk just above the
license plate, provides a video image
which appears on the navigation
screen of the area behind the
vehicle. It adds assistance to the
driver while reversing or reverse
parking the vehicle.
To use the camera system, place the transmission in R (Reverse); an
image will display on the navigation system screen. The area displayed
on the screen may vary according to the vehicle orientation and/or road
condition.
•(1) Rear bumper
•(2) Red zone
•(3) Yellow zone
•(4) Green zone
Always use caution while backing.
Objects in the red zone are closest
to your vehicle and objects in the
green zone are further away. Objects
are getting closer to your vehicle as
they move from the green zone to the yellow or red zones.

Note:If the system cannot be turned off in a MyKey™ equipped vehicle,
refer toMyKey™in theLocks and Securitychapter for more
information.
Note:If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to theMessage centerin theInstrument Cluster
chapter for instructions on reducing the sensitivity.
ACTIVE PARK ASSIST (APA) (IF EQUIPPED)
Active Park Assist (APA) will detect an available parallel parking space
and automatically steer the vehicle into the space (hands free) while you
control the accelerator, gearshift and brakes. The system will visually
and/or audibly instruct the driver to park the vehicle.
WARNING:This system is designed to be a supplementary park
aid. It is not intended to replace the driver’s attention and
judgment. The driver is responsible for avoiding hazards and
maintaining a safe distance and speed, even when the APA is in use.
Automatic Search for Parking Space
To start, press the APA control
switch (on the center console). The
message center will display ACTIVE
PARK SEARCHING. To designate
what side of the street to search on,
use the turn signal. The arrow
symbols >> and << in the message
center indicate on which side of the
vehicle APA will park. (If the turn
signal is not on, the system will
automatically search the passenger
side.)

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
Compliance Certification label). Consult your authorized dealer for
specific weight information.
•The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems — such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
•To avoid interference with other vehicle functions, such as anti-lock
braking systems, amateur radio users who install radios and antennas
onto their vehicle should not locate the Amateur Radio Antennas in
the area of the driver’s side hood.
•Electrical or electronic accessories or components that are added to
the vehicle by the authorized dealer or the owner may adversely affect
battery performance and durability.
