uses six sensors located in the front bumper
fascia to scan for obstacles up to 47 in
(120 cm) away from the front bumper fascia.
The warning display located above in the In-

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. The
instrument cluster will display the "CLEAN
PARK ASSIST SENSORS" message when any
of the rear sensor(s) is blocked by snow, mud,
or ice and the vehicle is shifted into REVERSE.
The instrument cluster will display the "CLEAN
PARK ASSIST SENSORS" message when any
of the front sensor(s) is blocked by snow, mud,
or ice and the vehicle is shifted into REVERSE
or DRIVE. The instrument 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
134
system has detected a faulted condition, the
EVIC will display the "CLEAN PARK ASSIST
SENSORS" or the "SERVICE PARK ASSIST
SYSTEM" message for as long as the vehicle is
in REVERSE or DRIVE (at speeds less than
11 mph/18 km/h). Under this condition Park-
Sense will not operate. Refer to "Electronic
Vehicle Information Center (EVIC)" in "Under-
standing Your Instrument Panel" for further in-
formation.
If the "CLEAN PARK ASSIST SENSORS" mes-
sage appears in the Electronic Vehicle Informa-
tion Center (EVIC) and the rear fascia/bumper
or front fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction, see
your authorized dealer. If "SERVICE PARK AS-
SIST SYSTEM" appears in the EVIC, see your
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 sen-
sors. Otherwise, you could damage the sen-
sors.
