STARTING AND OPERATING 177
While audible signals are emitted, the audio system is
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition occurs
for the external sensors, the signal is turned off after three seconds
(stopping warnings during maneuvers parallel to walls).

ParkSense Rear Park Assist Failure Indications
A malfunction of the ParkSense sensors or system is indi
-
cated, during REVERSE gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a message is
displayed on the instrument cluster display (if
equipped). Refer to “Warning Lights And
Messages” in “Getting To Know Your Instrument Panel” for
further information.

The sensors and wiring are tested continuously when the
ignition is in the MAR (ACC/ON/RUN) position. Failures are
indicated immediately if they occur when the system is on.

Even if the system is able to identify that a specific sensor is
in failure condition, the instrument cluster display shall
indicate that the ParkSense system is unavailable, without
reference to the sensor in failure condition. If even a single
sensor fails, the entire system must be disabled. The system
is turned off automatically.

192 STARTING AND OPERATING
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:
Do not cut or splice wiring into the vehicle’s wiring harness.
The electrical connections are all complete to the vehicle but
you must mate the harness to a trailer connector. Refer to the
following illustrations.NOTE:
• Disconnect trailer wiring connector from the vehicle
before launching a boat (or any other device plugged into
vehicle’s electrical connect) into water.
• Be sure to reconnect once clear from water area.
Four-Pin Connector
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg) loaded,
it should have its own brakes and they should be of
adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal effort,
and longer stopping distances.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING

Your vehicle is equipped with an automatic oil change indicator
system. The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.

Based on engine operation conditions, the oil change indi-
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extended engine idle time,
extremely hot or cold ambient temperatures will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since
last reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).

Your authorized dealer will reset the oil change indicator message
after completing the scheduled oil change. If a scheduled oil change
is performed by someone other than your authorized dealer, the
message can be reset by referring to the steps described under “Oil
Change Reset” in “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change intervals exceed
10,000 miles (16,000 km), 350 hours of engine run time or
12 months, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.

Severe Duty All Models

Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of engine
run time if the vehicle is operated in a dusty and off road environ -
ment or is operated predominantly at idle, or only very low engine
RPM. This type of vehicle use is considered Severe Duty.

Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual wear or damage. Rotate tires at the first sign of irregular wear, even if it
occurs before the oil indicator system turns on.
• Check the fluid levels of the coolant reservoir and brake master cylinder, fill as needed.
• Check function of all interior and exterior lights.

290 SERVICING AND MAINTENANCE
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to
geographic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on trees
and road surfaces during other seasons are highly corrosive
to the metal in your vehicle. Outside parking, which exposes
your vehicle to airborne contaminants, road surfaces on
which the vehicle is operated, extreme hot or cold weather
and other extreme conditions will have an adverse effect on
paint, metal trim, and underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resistance
built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of paint
and protective coatings from your vehicle.
The most common causes are:
• Road salt, dirt and moisture accumulation
• Stone and gravel impact• Insects, tree sap and tar
• Salt in the air near seacoast localities
• Atmospheric fallout/industrial pollutants
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution followed
by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
