ParkSense System Usage Precautions
NOTE:
Ensure that the rear 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
ParkSense.
When you turn ParkSense off, the instru -
ment cluster display will read “PARK -
SENSE OFF.” Furthermore, once you turn
ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
ParkSense, when on, will reduce the
volume of the radio when it is sounding a
tone.
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 ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
Use the ParkSense switch to turn the
ParkSense system off if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 inches (30 cm) from the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a
close object as a sensor problem, causing
the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be
displayed in the instrument cluster
display.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always
check carefully behind your vehicle, look
behind you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before
backing up. You are responsible for
safety and must continue to pay atten -
tion to your surroundings. Failure to do
so can result in serious injury or death.
Before using ParkSense, 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 loudspeaker sounds the contin -
uous 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.

vehicle moves closer to the obstacle, the
display will show the single arc moving closer
to the vehicle and the sound tone will change
from a single 1/2 second tone to slow, to
fast, to continuous.If an obstacle is detected in the left and/or
right front region, the display will show a
single flashing arc in the left and/or right
front region and will produce a fast sound
tone. As the vehicle moves closer to the
obstacle, the display will show the single arc
moving closer to the vehicle and the tone will
change from fast to continuous.
The vehicle is close to the obstacle when the
display shows one flashing arc and sounds a
continuous tone. The following chart shows

SERVICING AND MAINTENANCE
246
Plastic And Coated Parts
Use a specific product to clean vinyl uphol-
stery.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When
cleaning the lenses, care must be taken to
avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap solution may be used, but do not use
high alcohol content or abrasive
cleaners. If soap is used, wipe clean with
a clean damp cloth.
2. Dry with a soft cloth.
Leather Parts
Your leather upholstery can be best
preserved by regular cleaning with a damp
soft cloth. Small particles of dirt can act as
an abrasive and damage the leather uphol -
stery and should be removed promptly with a
damp cloth. Care should be taken to avoid
soaking your leather upholstery with any
liquid. Please do not use polishes, oils,
cleaning fluids, solvents, detergents, or
ammonia-based cleaners to clean your
leather upholstery. Application of a leather
conditioner is not required to maintain the
original condition. NOTE:
If equipped with light colored leather, it
tends to show any foreign material, dirt, and
fabric dye transfer more so than darker
colors. The leather is designed for easy
cleaning.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial house
-
hold-type glass cleaner. Never use an abra -
sive type cleaner. Use caution when cleaning
the inside rear window equipped with elec -
tric defrosters or windows equipped with
radio antennas. Do not use scrapers or other
sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are
using. Do not spray cleaner directly on the
mirror.
WARNING!
A frayed or torn belt could rip apart in a
collision and leave you with no protection.
Inspect the belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced
immediately. Do not disassemble or modify
the system. Seat belt assemblies must be
replaced after a collision if they have been
damaged (i.e., bent retractor, torn
webbing, etc.).
CAUTION!

Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani -
tizers to the plastic, painted, or decorated
surfaces of the interior may cause perma -
nent damage. Wipe away immediately.

Damage caused by these type of prod -
ucts may not be covered by your New
Vehicle Limited Warranty.
CAUTION!
Do not use Alcohol and Alcohol-based and/
or Ketone based cleaning products to
clean leather upholstery, as damage to the
upholstery may result.
