400SERVICING AND MAINTENANCE
After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on
the cold windshield. Windshield washer solution
used with water as directed on the container,
aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to
paint or trim.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, nor is periodic maintenance
required.
PRESSURE WASHING
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to “Jump
Starting Procedure” in “In Case Of Emer -
gency” for further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds.
Wash hands after handling.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is
attached to the positive post and the nega -
tive cable is attached to the negative post.
Battery posts are marked positive (+) and
negative (-) and are identified on the battery
case. Cable clamps should be tight on the
terminal posts and free of corrosion.
If a “fast charger” is used while the battery
is in the vehicle, disconnect both vehicle
battery cables before connecting the
charger to the battery. Do not use a “fast
charger” to provide starting voltage.
CAUTION!
Cleaning the engine compartment with a high
pressure washer is not recommended.
Precautions have been taken to safeguard all
parts and connections however, the
pressures generated by these machines is
such that complete protection against water
ingress cannot be guaranteed.

represent higher levels of performance
on the laboratory test wheel, than the
minimum required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than
21 days, 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.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.

MULTIMEDIA531
AUX Mode
AUX Mode is entered by inserting a AUX device
using a stereo cable with a 3.5 mm audio jack
into the AUX port or by pushing the MEDIA
button located on the faceplate. Once in Media
Mode, press the Source button on the
touchscreen, and select the AUX button.
Inserting Auxiliary Device
Gently insert the Auxiliary device cable into the
AUX Port. If you insert an Auxiliary device with
the ignition on, the unit will switch to AUX mode
and begin to play when you insert the device
cable.
Controlling The Auxiliary Device
The control of the Auxiliary device (e.g.,
selecting playlists, play, fast forward, etc.)
cannot be provided by the radio; use the device
controls instead. Adjust the volume with the
VOLUME rotary knob or with the volume of the
attached device.
The radio unit is acting as the amplifier for audio
output from the Auxiliary device. Therefore, if
the volume control on the Auxiliary device is set
too low, there will be insufficient audio signal for
the radio unit to play the music on the device.
