•Do not remove any screws from the sensor or the
sensor mount. Doing so could cause an ACC system
malfunction or failure and require a sensor re-
alignment.
•If the sensor is damaged due to an accident, see your
authorized dealer for service.
•Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “ACC Off”
state and will resume function by simply reactivating it.
NOTE:Installing a vehicle front-end protector or an
aftermarket grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit ACC
operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displaysACC
UNAVAILABLE,there may be a temporary malfunction
that limits ACC functionality. In this case, ACC will be
temporarily unavailable. If this occurs, try activating
ACC again later, following a key cycle. If the problem
persists, see your authorized dealer.

Service ACC Warning
If the system turns off, and the EVIC displays “SERVICE
ACC,” it indicates there is an internal system fault that
requires service from an authorized dealer.
Precautions While Driving with ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Adding a Trailer Hitch
The weight of a trailer hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a hitch, such as reduced
detection range, please see your authorized dealer for
service.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel. There will not be
sufficient distance to the vehicle ahead. The offset vehicle
may move in and out of the line of travel, which can
cause your vehicle to brake or accelerate unexpectedly.

Turns and Bends
In turns or bends, ACC may detect a vehicle ahead too
late or too early. This may cause your vehicle to brake late
or unexpectedly. Give extra attention in curves and be
ready to apply the brakes if necessary. Be sure to select an
appropriate speed while driving in curves.ACC may occasionally provide braking and/or a driver
alert that you consider unnecessary. This may be the
system’s response to signs, guardrails, and other station-
ary objects in a curve. This may also occur at the base of
dramatic hills. This is normal operation and your vehicle
does not require service.
Using ACC on Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.

Lane Changing
ACC will not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and
it will not until it may be too late to take action. ACC will
not detect a vehicle until it is completely in the lane.There will not be sufficient distance to the lane-changing
vehicle. Always be attentive and ready to apply the
brakes if necessary.

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There will not be suffi-
cient distance to the vehicle ahead.
Stationary Objects and Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and
the vehicle ahead is stopped in your lane. Always be
attentive and ready to apply the brakes if necessary.

General Information
CLASS 1 LASER PRODUCT
Classification Specifications:

REAR PARK ASSIST SYSTEM
The Rear Park Assist System is a driver aid that senses for
obstacles behind the vehicle. Refer to the Warnings,
Cautions, and Notes in this section for system limitations
and usage recommendations.
The Rear Park Assist System is active when the driver
shifts the transmission into the REVERSE position, and
the parking brake is not applied, and the vehicle speed is
less than 10 mph (16 km/h).The system can be turned on or off through the Electronic
Vehicle Information Center (EVIC) when the vehicle is in
PARK. Refer to “Personal Settings (Customer Program-
mable Features)” under “Electronic Vehicle Information
Center (EVIC)” in Section 4.
The system uses four sensors located in the rear bumper
to scan for obstacles up to 59 in (150 cm) away from the
rear bumper fascia. The warning display located above
the rear window provides both visible and audible
warnings to indicate the range of the object.

The warning display contains two sets of yellow and red
LEDs, one set to warn of obstacles behind the left rear of
the vehicle and the other set to warn of obstacles behind
the right rear of the vehicle. The driver can view the LEDs
either through the rear view mirror or by looking at the
display above the rear window.
The system dimly illuminates the two outer most yellow
LEDs when it is ON and detecting no obstacles. The
following chart shows the warning display operation
when the system is detecting an obstacle:
