6 –68 Maintenance and Care
Appearance Care 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 plastic parts or paint
damage. Interior Care WARNING Do not spray water into the vehicle
cabin:
Spraying water into the vehicle cabin is
dangerous as electrical devices such as
the audio and switches could get wet
resulting in a malfunction or vehicle
fire.
NOTE 
Do not wipe the interior using alcohol,
chlorine bleach, or organic solvents
such as thinner, benzene, and gasoline.
Otherwise, it may cause discoloration
or stains. 
Rubbing hard with a stiff brush or cloth
may cause damage.
If the vehicle interior becomes soiled
by any of the following, wipe it off
immediately using a soft cloth.
Leaving it uncleaned could cause
discoloration, stains, cracks, or peeling
of the coating, and it will make it hard to
wipe off later. 
Beverage or fragrance 
Grease or oil 
Soiling
Seat Belt Maintenance
1. Clean the soiled area by lightly dabbing
it with a soft cloth soaked in a mild
detergent (approx. 5%) diluted with
water.
2. Wipe off the remaining detergent using
a cloth soaked in clean water and
wrung out well.
3. Before retracting seat belts which have
been pulled out for cleaning, dry them
off thoroughly and make sure there is
no remaining moisture on them.

Battery Runs Out
Jump-StartingJump-starting is dangerous if done incorrectly. So follow the procedure carefully. If you
feel unsure about jump-starting, we strongly recommend that you have a competent service
technician do the work.
WARNING Follow These Precautions Carefully:
To ensure safe and correct handling of the battery, read the following precautions
carefully before using the battery or inspecting it.
Do not allow the positive ( ) terminal to contact any other metal object that
could cause sparks:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries. When working near a battery, do
not allow metal tools to contact the positive (
) or negative ( ) terminal of the battery.
Keep all flames, including cigarettes, and sparks away from open battery cells:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries.
Do not jump-start a frozen battery or one with a low fluid level:
Jump-starting a frozen battery or one with a low fluid level is dangerous. It may rupture
or explode, causing serious injury.
Connect the negative cable to a good ground point away from the battery:
Connecting the end of the second jumper cable to the negative (
) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper cables away from parts that will be moving:
Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous. The
cable could get caught when the engine starts and cause serious injury.

7 –25 If Trouble Arises
Battery Runs Out1. Remove the battery cover.

2. Make sure the booster battery is 12
V and that its negative terminal is
grounded.
3. If the booster battery is in another
vehicle, do not allow both vehicles
to touch. Turn off the engine of the
vehicle with the booster battery and
all unnecessary electrical loads in both
vehicles.
4. Connect the jumper cables in the exact
sequence as in the illustration. 
Connect one end of a cable to the
positive terminal on the discharged
battery (1). 
Attach the other end to the positive
terminal on the booster battery (2). 
Connect one end of the other cable to
the negative terminal of the booster
battery (3). 
Connect the other end to the ground
point indicated in the illustration
away from the discharged battery (4).
5. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
6. When finished, carefully disconnect the
cables in the reverse order described in
the illustration. 7. If the battery cover has been removed,
install it in the reverse order of
removal.
NOTE
Verify that the covers are securely
installed.
