— Hill Descent Control (HDC) Indicator Light — If
Equipped
This indicator shows when the Hill Descent Control (HDC)
feature is turned on. The lamp will be on solid when HDC is
armed. HDC can only be armed when the transfer case is in
the “4WD LOW” position and the vehicle speed is less then
20 mph (32 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC indicator light
will flash on/off.
Blue Indicator Lights
— High Beam Indicator Light
This indicator light will illuminate to indicate that the high
beam headlights are on. With the low beams activated, push
the multifunction lever forward (toward the front of the
vehicle) to turn on the high beams. Pull the multifunction
lever rearward (toward the rear of the vehicle) to turn off the
high beams. If the high beams are off, pull the lever toward
you for a temporary high beam on, "flash to pass" scenario.
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating properly,
your vehicle will provide excellent performance and fuel
economy, as well as engine emissions well within current
government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see an
authorized dealer for service as soon as possible.
CAUTION!
• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle must
be serviced before any emissions tests can be
performed.
• If the MIL is flashing while the vehicle is running, severe catalytic converter damage and power loss will
soon occur. Immediate service is required.

212 SAFETY
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on
the nature of the event, the ORC will determine whether to
have the Enhanced Accident Response System perform the
following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor (If Equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as thebattery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System.
• Unlock the power door locks.
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
• Turn off the Fuel Filter Heater, Turn off the HVAC Blower Motor, Close the HVAC Circulation Door • Cut off battery power to the:
• Engine
• Electric Motor (if equipped)
• Electric power steering
• Brake booster
• Electric park brake
• Automatic transmission gear selector
• Horn
• Front wiper
• Headlamp washer pump
NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.

SERVICING AND MAINTENANCE 471
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.
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash your vehicle in
the shade using Mopar Car Wash, or a mild car wash soap,
and rinse the panels completely with clear water.
• If insects, tar, or other similar deposits have accumulated on your vehicle, use Mopar Super Kleen Bug and Tar
Remover to remove.
• Use a high quality cleaner wax, such as Mopar Cleaner Wax to remove road film, stains and to protect your paint
finish. Take care never to scratch the paint.
• Avoid using abrasive compounds and power buffing that may diminish the gloss or thin out the paint finish.
CAUTION!
• Do not use abrasive or strong cleaning materials such as steel wool or scouring powder that will scratch metal
and painted surfaces.
• Use of power washers exceeding 1,200 psi (8,274 kPa) can result in damage or removal of paint and decals.
