Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
 Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.
NOTICE
Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.
 Add only “T oyota Super Long Life Coolant” or similar
high quality ethylene glycol based nonsilicate,
nonamine, nonnitrite, and nonborate coolant with
longlife hybrid organic acid technology to fill the
radiator. “Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45% deionized water
(for Canada).
 If you spill some of the coolant, be sure to wash it off
with water to prevent it from damaging the parts or
paint.
 Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.
 Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.
Do not overfill automatic transmission fluid and
power steering fluid, or the transmission and power
steering could be damaged.
 Be careful not to scratch the glass surface with the
wiper frame.

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
Check the battery condition by the indicator color.
1BLUE — Good condition.
2WHITE — Charging necessary. Have the battery
checked by your Lexus dealer.
3RED — Have the battery checked by your Lexus dealer.
NOTICE
Do not refill the battery with water.

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
