PARKSENSE

姞

REAR PARK ASSIST — IF

EQUIPPED

The ParkSense

威 Rear Park Assist system provides visual

and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense

威 System

Usage Precautions for limitations of this system and
recommendations.

ParkSense

威 will retain the last system state (enabled or

disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.

ParkSense

威 can be active only when the shift lever is in

REVERSE. If ParkSense

威 is enabled at this shift lever

position, the system will remain active until the vehicle
speed is increased to approximately 11 mph (18 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
10 mph (16 km/h).

ParkSense

Sensors

The four ParkSense

威 sensors, located in the rear fascia/

bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.

The ParkSense

威 switch LED will be ON when

ParkSense

威 is disabled or defective. The ParkSense威

switch LED will be OFF when the system is enabled.

Service The ParkSense

姞

Rear Park Assist System

When the ParkSense

威 Rear Park Assist System is mal-

functioning, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
“SERVICE PARK ASSIST SYSTEM” message. Refer to

“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. When the shift lever is moved to REVERSE and the
system has detected a faulted condition, the EVIC will
display the “SERVICE PARK ASSIST SYSTEM” message
for as long as the vehicle is in REVERSE. Under this
condition, ParkSense

威 will not operate.

If “SERVICE PARK ASSIST SYSTEM” appears in the
EVIC make sure the rear fascia/bumper is clean and clear
of snow, ice, mud, dirt or other obstruction and then cycle
the ignition. If the message appears again, see an autho-
rized dealer.

Cleaning The ParkSense

姞

System

Clean the ParkSense

威 sensors with water, car wash soap

and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.

System Usage Precautions

NOTE:

• Ensure that the rear bumper is free of snow, ice, mud,

dirt and debris to keep the ParkSense

威 system operat-

ing properly.

• Jackhammers, large trucks, and other vibrations could

affect the performance of ParkSense

威.

• When you turn ParkSense威 off, the instrument cluster

will display “PARK ASSIST OFF.” Furthermore, once
you turn ParkSense

威 off, it remains off until you turn

it on again, even if you cycle the ignition key.

• When you move the shift lever to the REVERSE

position and ParkSense

威 is turned off, the instrument

cluster will display “PARK ASSIST OFF” message for
as long as the vehicle is in REVERSE.

• ParkSense威, when on, will MUTE the radio when it is

sounding a tone.

• Clean the ParkSense威 sensors regularly, taking care

not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense

威 system might not detect an

obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.

• Objects such as bicycle carriers, trailer hitches, etc.,

must not be placed within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the EVIC.

182

UNDERSTANDING THE FEATURES OF YOUR VEHICLE

CAUTION!

• ParkSense威 is only a parking aid and it is unable

to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected or not detected at all. Obstacles located
above or below the sensors will not be detected
when they are in close proximity.

• The vehicle must be driven slowly when using

ParkSense

威 in order to be able to stop in time

when an obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using ParkSense

威.

WARNING!

• Drivers must be careful when backing up even

when using the ParkSense

威 Rear Park Assist Sys-

tem. Always check carefully behind your vehicle,
look behind you, and be sure to check for pedes-
trians, animals, other vehicles, obstructions, and
blind spots before backing up. You are responsible
for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE

183

WARNING! (Continued)

• Before using the ParkSense威 Rear Park Assist

System, it is strongly recommended that the ball
mount and hitch ball assembly is disconnected
from the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury or
damage to vehicles or obstacles because the hitch
ball will be much closer to the obstacle than the
rear fascia when the warning display turns on the
single flashing arc and sounds the continuous
tone. Also, the sensors could detect the ball mount
and hitch ball assembly, depending on its size and
shape, giving a false indication that an obstacle is
behind the vehicle.

GARAGE DOOR OPENER — IF EQUIPPED

HomeLink

威 replaces up to three hand-held transmitters

that operate devices such as garage door openers, motor-
ized gates, lighting or home security systems. The
HomeLink

威 unit is powered by your vehicles 12 Volt

battery.

The HomeLink

威 buttons, located on either the overhead

console, headliner or sunvisor, designate the three differ-
ent HomeLink

威 channels. The HomeLink威 indicator is

Canadian/Gate Operator Programming

For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission.

Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLink

威

UNDERSTANDING THE FEATURES OF YOUR VEHICLE

189

to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out in the same manner.

It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.

1. Turn the ignition switch to the ON/RUN position.

2. Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
away from the HomeLink

威 button you wish to program

while keeping the HomeLink

威 indicator light in view.

3. Continue to press and hold the HomeLink

威 button,

while you press and release (“cycle”), your hand-held
transmitter every two seconds until HomeLink

威 has

successfully accepted the frequency signal. The indicator
light will flash slowly and then rapidly when fully
trained.

4. Watch for the HomeLink

威 indicator to change flash

rates. When it changes, it is programmed. It may take up
to 30 seconds or longer in rare cases. The garage door
may open and close while you are programming.

5. Press and hold the programmed HomeLink

威 button

and observe the indicator light.

• If the indicator light stays on constantly, program-

ming is complete and the garage door/device
should activate when the HomeLink

威 button is

pressed.

• To program the two remaining HomeLink威 buttons,

repeat each step for each remaining button. DO
NOT erase the channels.

If you unplugged the garage door opener/device for
programming, plug it back in at this time.
