ParkSense System Usage
Precautions
NOTE:
• Ensure that the front and rear bumpers
are free of dirt and debris to keep the
ParkSense system operating properly.
• Jackhammers, large trucks, and other vi-
brations could affect the performance of
ParkSense .
• When you turn ParkSense off, the instru-
ment cluster will display "PARK ASSIST
DISABLED." Furthermore, once you turn
ParkSense off, it remains off until you
turn it on again, even if you cycle the
ignition key.
94
• When you move the shift lever to the
REVERSE position and ParkSense
turned off, a single chime will sound once
per ignition cycle and the instrument
cluster will display "PARK ASSIST DIS-
ABLED."
• ParkSense , when on, will MUTE the radio
when it is sounding a tone.
• If a ParkSense system malfunction oc-
curs, a single chime will sound once per
ignition cycle. In addition, the Electronic
Vehicle Information Center (EVIC) will dis-
play "SERVICE PARK ASSIST SYSTEM"
and the LED in the ParkSense switch will
illuminate. If this occurs, see your autho-
rized dealer for service.
• Clean the ParkSense 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 system might
not detect an obstacle near the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is present.
• Objects must not be within 12 in (30 cm)
is 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 "SER-
VICE PARK ASSIST SYSTEM" message to
be displayed in the instrument cluster.
CAUTION!
• ParkSense is only a parking aid and it is
unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sen-
sors will not be detected when they are in
close proximity.
• The vehicle must be driven slowly when
using ParkSense to be able to stop in time
when the obstacle is detected. It is recom-
mended that the driver looks over his/her
shoulder when using ParkSense .
