CHECKING BATTERY CONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive
hydrogen gas.
 Do not cause a spark by contacting the battery
terminals with tools.
 Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive
sulfuric acid.
 Avoid contact with eyes, skin or clothes.
 Never inhale or swallow electrolyte.
 Wear protective safety glasses when working near
the battery.
 Keep children away from the battery.
EMERGENCY MEASURES
 If electrolyte gets in your eyes, flush your eyes with
clean water for at least 15 minutes and get immediate
medical attention. If possible, continue to apply
water with a sponge or cloth while traveling to the
medical office.

ELECTRICAL COMPONENTS
552
If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a pain or burn, get medical
attention immediately.
 If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin, so
immediately take off the exposed clothing and follow
the procedure above, if necessary.
 If you accidentally to swallow electrolyte, drink a
large quantity of water or milk. Follow with milk of
magnesia, beaten raw egg or vegetable oil. Then go
immediately for emergency help.Checking battery exterior
1Terminals2Holddown clamp
Check the battery for corroded or loose connections,
cracks, or loose holddown clamps.
1. If the battery is corroded, wash it off with a solution of warm
water and baking soda. Coat the terminals with grease to
prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts — but
do not overtighten.
3. Tighten the hold −down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.

ELECTRICAL COMPONENTS

NOTICE
Make sure the engine and all accessories are turned
off before performing maintenance.
 When checking the battery, remove the ground cable
first and reinstall it last.
 Be careful not to cause a short circuit with tools.
 Take care no solution gets into the battery when
washing it.
If the battery is disconnected or run down
The power windows and moon roof may not operate
automatically and the jam protection function will not function
correctly after you reconnect, replace or recharge the battery.
In any of these cases, you should normalize the power
windows and moon roof. To normalize the power windows and
moon roof, see pages 42 and 105.
Checking battery condition

BATTERY RECHARGINGPRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
2. Make sure the power switch on the recharger is off when
connecting the charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an unconfined area. Do
not charge the battery in a garage or closed room
where there is not sufficient ventilation.
 Only do a slow charge (5 A or less). Charging at a
quicker rate is dangerous. The battery may explode
causing personal injuries.
NOTICE
Never recharge the battery while the engine is running.
Also, make sure all accessories are turned off.
CHECKING AND REPLACING THE BLADE TYPE FUSES

1. Turn the ignition switch off and open the fuse box lid.
Determine which fuse may be causing the problem. The lid of
the fuse box shows the name of the circuit for each fuse.2. Make sure the inoperative component is turned off. Pull
the suspected fuse straight out with the pullout tool and
check it. If it has blown, push a new fuse into the clips.
