Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in ashort time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use), jump
start it from another vehicle’s battery or
recharge it by slow charging (trickle)
for 10 hours.
If the battery gradually discharges because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.CALIFORNIA PROPOSI-
TION 65 WARNING
Battery posts, terminals, and relat-
ed accessories contain lead and
lead compounds, chemicals known
to the State of California to cause
cancer, birth defects and reproduc-
tive harm. Batteries also contain
other chemicals known to the State
of California to cause cancer. Wash
hands after handling.
CAUTION
When you don’t use the vehicle
for a long time in the low temper-ature, remove the battery andstore it indoors.
Always charge the battery fully to prevent the battery case dam-aged in low temperatures.
If you connect unauthorized elec- tronic devices to the battery, thebattery may be discharged. Never use unauthorized devices.
(Continued)
When lifting a plastic-cased bat- tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cables
are connected.
The electrical ignition system works with high voltage. Never
touch these components with the

Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
Do not use strong soap, chemical
detergents or hot water, and donot wash the vehicle in directsunlight or when the body of thevehicle is warm.
Be careful when washing the side windows of your vehicle.Especially, with high-pressure water, water may leak through thewindows and wet the interior.
To prevent damage to the plastic parts and lamps, do not cleanwith chemical solvents or strongdetergents.
WARNING
Do not wash the engine compart-
ment and trunk with water. The
hybrid system is located in the
engine compartment and trunk. If
water enters the engine or hybrid
battery in the trunk, electric shocks
or burns may result in serious injury
or death.
CAUTION
Water washing in the engine com- partment including high pressurewater washing may cause the fail- ure of electrical circuits or engineand related components located in the engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components andair ducts inside the vehicle as this may damage them.

affected. Also, its fire-resistant properties
can be reduced if the material is not
properly maintained.

soap solution recommended for cleaning
upholstery or carpet. Follow the instruc-
tions provided with the soap. Do not
bleach or re-dye the webbing because

cle become fogged (that is, covered with
an oily, greasy or waxy film), they should
be cleaned with glass cleaner. Follow the
directions on the glass cleaner container.

WARNING
Do not wash the engine room and
trunk with water. The hybrid system
is located in engine room and
trunk. If water comes into the
engine room or hybrid battery in
trunk, electric shock or burns that
may result in serious injury or
death may occur.
