TIRE PRESSURE SENSOR FAULT— Displayed when a tire pressure
sensor is malfunctioning, or your spare tire is in use. For more
information on how the system operates under these conditions, refer to
Tire Pressure Monitoring System (TPMS)in theTires, Wheels and
Loadingchapter. If the warning stays on or continues to come on,
contact your authorized dealer as soon as possible.
POWER STEERING ASSIST FAULT— The power steering system
has disabled power steering assist due to a system error; service is
required.
SERVICE POWER STEERING— The power steering system has
detected a condition that requires service.
SERVICE POWER STEERING NOW— The power steering system
has detected a condition that requires service immediately.
TRUNK AJAR— Displayed when the trunk is not completely closed.
REMOVE OBJECTS NEAR PASS SEAT— Displayed when objects
are by the passenger seat. After the objects are moved away from the
seat, if the warning stays on or continues to come on contact your
authorized dealer as soon as possible.
AWD OFF (if equipped)— Displayed when the AWD system has been
automatically disabled to protect itself. This is caused by operating the
vehicle with the compact spare tire installed or if the system is
overheating. The AWD system will resume normal function and clear this
message after driving a short distance with the road tire re-installed or
after the system is allowed to cool.
CHECK AWD (if equipped)— Displayed in conjunction with the
Throttle Control/Transmission/AWD
light when the AWD system is
not operating properly. If the warning stays on or continues to come on,
contact your authorized dealer as soon as possible.
ENGINE OIL CHANGE SOON— Displayed when the engine oil life
remaining is 5% to 1%.
OIL CHANGE REQUIRED— Displayed when the oil life left reaches
0%.

Resuming the set speed
Press and release the RESUME
control. This will automatically
return the vehicle to the previously
set speed. The set speed will display
continuously in the message center
while ACC is active.
Note:RESUME should only be used
if the driver is aware of the set
speed and intends to return to it.
Low speed automatic cancellation
ACC is not functional at vehicle speeds below 18 mph (30 km/h). Once
the vehicle speed drops below 18 mph (30 km/h), an audible alarm will
sound, the head’s up display will flash and the automatic braking will be
released.
Hilly condition usage
It is recommended that the driver select a lower gear position when ACC
is active in situations such as prolonged downhill driving on steep grades
(i.e., driving in mountainous areas). In these situations, additional engine
braking is needed to reduce the load on the vehicle’s regular brake
system to prevent them from overheating. For more information,
referenceAutomatic transmission operationin theDrivingchapter.
Note:If ACC is applying brakes for an extended period of time, an
audible alarm will sound, the head’s up display will flash and ACC will
shut down. This is to allow the brakes to cool down. When the brakes
have cooled down, the ACC will again function normally.

HomeLinkWireless Control System (if equipped)
The HomeLinkWireless Control
System, located on the driver’s visor,
provides a convenient way to
replace up to three hand-held
transmitters with a single built-in
device. This feature will learn the
radio frequency codes of most
transmitters to operate garage
doors, entry gate operators, security systems, entry door locks, and
home or office lighting.
WARNING:When programming your HomeLinkWireless
Control System to a garage door or gate, be sure that people and
objects are out of the way to prevent potential injury or damage.

•It is recommended to select the “M” gear position when additional
engine braking is needed. In situations such as prolonged downhill
driving on steep grades (i.e., driving in mountainous areas), additional
engine braking is needed to reduce the load on the vehicle’s regular
brake system to prevent them from overheating. For more information
on transmission operation and gear positions, seeAutomatic
transmission operationin theDrivingchapter.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer toSpecial operating conditionsin the
Scheduled Maintenance Guidechapter.
Trailer towing tips
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to the “M” position,
then use the paddle shifters to manually shift to a lower gear. Do not
apply the brakes continuously, as they may overheat and become less
effective. For more information on transmission operation and gear
positions, seeAutomatic transmission operationin theDriving
chapter.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle for personal travel (such as behind a motor home or a
truck).
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to theClimate
Controlschapter for more information.
In case of roadside emergency with a disabled vehicle, please refer to

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 brake lamps 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
brake lamps 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.
