a. If the battery is corroded, wash it off

with a solution of warm water and bakingsoda. Coat the outside of the terminalswith grease to prevent further corrosion.

b. If the terminal connections are loose,tighten their clamp nuts—but do notovertighten.

NOTICE

Be sure the engine and all accesso-

ries are off before performing maintenance.

When checking the battery, remove

the ground cable from the negative terminal (”- ” mark) first and rein- stall it last.

Be careful not to cause a short circuit with tools.

Take care no solution gets into the

Battery recharging precautionsDuring recharging, the battery is pro-ducing hydrogen gas.

Therefore, before recharging:

1. If recharging with the battery installedon the vehicle, be sure to disconnect

the ground cable.

2. Be sure the power switch on the re-charger is off when connecting the

charger cables to the battery and whendisconnecting them.

CAUTION

Always charge the battery in an un-

confined area. Do not charge thebattery in a garage or closed roomwhere there is not sufficient ventila-

tion.

Only do a slow charge (5 A orless). Charging at a quicker rate is

dangerous. The battery may ex-plode, causing personal injuries.

NOTICE

Never recharge the battery while the

engine is running. Also, be sure all accessories are turned off.

If the headlights or other electricalcomponents do not work, check the

fuses. If any of the fuses are blown,they must be replaced.

See ”Fuse locations” in Chapter 7- 1 forlocations of the fuses.

Turn the ignition switch and inoperative

component off. Pull a suspected fusestraight out and check it.

Determine which fuse may be causing theproblem. The lid of the fuse box showsthe name of the circuit for each fuse. See

Part 8 of this manual for the functions

controlled by each circuit.

Type A fuses can be pulled out by usingthe pull- out tool. The location of the pull-out tool is shown in the illustration.

If you are not sure whether the fuse hasblown, try replacing the suspected fusewith one that you know is good.

If the fuse has blown, push a new fuseinto the clip.

Only install a fuse with the amperage rat-ing designated on the fuse box lid.

If you do not have a spare fuse, in anemergency you can pull out the ”PWR

OUTLET” or ”A.C” fuse, which may bedispensable for normal driving, and use itif its amperage rating is the same.

If you cannot use one of the same amper-age, use one that is lower, but as closeas possible to the rating. If the amperage

is lower than that specified, the fusemight blow out again but this does notindicate anything wrong. Be sure to get

the correct fuse as soon as possible andreturn the substitute to its original clip.

It is a good idea to purchase a set of

spare fuses and keep them in your ve-hicle for emergencies.

If the new fuse immediately blows out,there is a problem with the electrical sys-tem. Have your Toyota dealer correct it as

soon as possible.

CAUTION

Never use a fuse with a higher am-

perage rating, or any other object, inplace of a fuse. This may cause ex-tensive damage and possibly a fire.

washer fluid containing antifreeze. Thisproduct is available at your Toyota dealerand most auto parts stores. Follow the

manufacturer’s directions for how much tomix with water.
