his coating.
CAUTION
Do not use any detergent other than mild
detergent. Before using any detergent,
verify the ingredients. Otherwise, the
product could discolor or stain the
aluminum wheels.

Do not use a wire brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold wate r. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash that uses high-speed
or hard brushes.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents
or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plast ic parts or paint
damage.

Cell Phones Warning
▼Cell Phones Warning
WA R N I N G
Please comply with the legal regulations
concerning the use of communication
equipment in vehicles in your country:
Use of any electrical devices such as cell
phones, computers, portable radios,
vehicle navigation or other devices by the
driver while the vehicle is moving is
dangerous. Dialing a number on a cell
phone while driving also ties-up the driver's
hands. Use of these devices will cause the
driver to be distracted and could lead to a
serious accident. If a
passenger is unable to
use the device, pull off the right-of-way to a
safe area before use. If use of a cell phone is
necessary despite this warning, use a
hands-free system to at least leave the
hands free to drive the vehicle. Never use a
cell phone or other electrical devices while
the vehicle is moving and, instead,
concentrate on the full-time job of driving.
