1Terminals 2Hold±down clamp
Check the battery for corroded or loose
connections, cracks, or loose hold±down 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.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 batterywhen washing it.
Checking battery fluid
There are 2 types of batteries: maintenance type
and non±maintenance type.
A non±maintenance battery has ºMAINTENANCE
FREE BATTERYº on its top. A maintenance type battery
does not have such indication.
Maintenance type battery
Check the fluid condition by the fluid level lines on the
side of the battery. Or if the battery has a hydrometer on
its top, you can also check the hydrometer.
Non±maintenance battery
Check the battery condition by the hydrometer on the top
of the battery.

2. Make sure the inoperative component is turned
off. Pull the suspected fuse straight out with the
pull±out tool and check it. If it has blown, push a new
fuse into the clips.

a. Look carefully at the fuse. If the thin wire is broken,
the fuse has blown. If you are not sure or if it is too dark
to see, try replacing the suspected fuse with one of the
same value that you know is good.
b. Only install a fuse with the amperage rating
designated on the fuse box lid.
If you do not have a spare fuse, in an emergency you can
pull out the ºRAD NO.1º, ºRAD NO.2º or ºPWR
OUTLETº fuse, which may be dispensable for normal
driving, and use it if its amperage rating is the same.
If you cannot use one of the same amperage, use one
lower than, but as close as possible to, the amperage.
If the amperage is lower than that specified, the fuse
might blow out again but this does not indicate anything
wrong. Be sure to get the correct fuse as soon as
possible and return the substitute to its original clips.It is a good idea to purchase a set of spare fuses and
keep them in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem
with the electrical system. Have your Lexus dealer
correct it as soon as possible.
