Service The ParkSense® Park Assist
System
When the ParkSense Park Assist System is
malfunctioning, the instrument cluster will actu-
ate a single chime, once per ignition cycle, and
it will display the "CLEAN PARK ASSIST SEN-
SORS" or the "SERVICE PARK ASSIST SYS-
TEM" message. The instrument cluster will dis-
play the "CLEAN PARK ASSIST SENSORS"
message when any of the rear or front sensors
are blocked by snow, mud, or ice. The instru-
ment cluster will display the "SERVICE PARK
ASSIST SYSTEM" message when any of the
rear or front sensors are damaged and require
service.
When the shift lever is moved to REVERSE or
DRIVE and the system has detected a faulted
condition, the EVIC will display the "CLEAN
PARK ASSIST SENSORS" or the "SERVICE
PARK ASSIST SYSTEM" message for appro-
priately five seconds. Then, when the shift lever
is moved to REVERSE, the EVIC will display
the "PARK ASSIST SYSTEM OFF" message for
as long as the vehicle is in REVERSE. Under
this condition ParkSense will not operate. Refer
to "Electronic Vehicle Information Center
(EVIC)" in "Understanding Your Instrument
Panel" for further information.
If the "CLEAN PARK ASSIST SENSORS" mes-
sage appears in the Electronic Vehicle Informa-
tion Center (EVIC) make sure the outer surface
and the underside of the rear fascia/bumper
and/or front fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction and
then cycle the ignition. If the message continues
to appear, see an authorized dealer.
If the "SERVICE PARK ASSIST SYSTEM" mes-
sage appears in the EVIC, see an authorized
dealer.
Cleaning The ParkSense® System
Clean the ParkSense® 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 damage the sensors.
ParkSense® System Usage
Precautions
NOTE:
• Ensure that the front and rear bumper are
free of snow, ice, mud, 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 in-
strument cluster will display "PARK AS-
SIST SYSTEM OFF." Furthermore, once
you turn ParkSense® 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 is
turned off, the instrument cluster will dis-
play "PARK ASSIST SYSTEM OFF" mes-
sage for as long as the vehicle is in
REVERSE.
