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

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.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may
need to access this information to assist with
the diagnosis and service of your vehicle and
emissions system Ú page 220.
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.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an acci -
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

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 the battery 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 Circula -
tion 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 place 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.

Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident
Response System functions after an event, the
ignition switch must be changed from ignition
START or ON/RUN to ignition OFF. 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.
After an accident, if the vehicle will not start
after performing the reset procedure, the
vehicle must be towed to an authorized dealer
to be inspected and to have the Enhanced
Accident Response System reset.

SERVICING AND MAINTENANCE427
STORING THE VEHICLE
If you are storing your vehicle for more than
three weeks, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
Disconnect the negative cable from battery.

Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for
about five minutes in the fresh air and high
blower setting. This will ensure adequate
system lubrication to minimize the possibility
of compressor damage when the system is
started again.

BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
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.
