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 happen 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.
1. Check the battery for corroded or loose connections,
cracks, or loose hold-down clamps.
a. 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.
b. If the connections are loose, tighten the clamp bolts-but do
not overtighten.
c. Tighten the hold-down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.
NOTICE:

Be sure the engine and all accessories are off before
performing maintenance.

Remove the ground cable first and reinstall last.

Be careful not to cause a short circuit with tools.

Take care no solution gets into the battery when
washing it.
2. Check the hydrometer as shown.
BLUE − Good condition.
WHITE − Charging necessary. Have the battery checked by
your Lexus dealer.
RED − Have the battery checked by your Lexus dealer.

BATTERY RECHARGING
PRECAUTIONS
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. Be 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 (5A or less). Charging at a
quicker rate is dangerous.
NOTICE:
Never recharge the battery while the engine is running.
Also, be sure all accessories are turned off.
