Jeep Wrangler: PARKSENSE REAR PARK ASSIST — IF EQUIPPED / Cleaning The ParkSense System
Clean the Rear Park Assist sensors with water,
car wash soap and a soft cloth. Do not use
rough or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4 inches
(10 cm) from the sensors. Do not scratch or
poke the sensors.
During vehicle start up, when the ParkSense
Rear Park Assist System has detected a faulted
condition, the instrument cluster display will
actuate a single chime, once per ignition cycle,
and it will display the “PARKSENSE
UNAVAILABLE WIPE REAR SENSORS” or the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message...
NOTE:
Ensure that the rear fascia/bumper is free of
snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other vibrations
could affect the performance of Park-
Sense...

While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see a dealer immediately. Use
of gasoline with an octane number lower than
recommended octane can cause engine failure
and may void the New Vehicle Limited Warranty...
