Checking the battery status –

– Instructions

The meaning of the individual warning

symbols on the top of the battery is as

follows:

WARNING

BATTERY INSTRUCTIONS

is flammable and explosive.

Do not smoke, do not use

open flames, avoid sparks

• Be careful not to spark the battery by

touching the tool.

• Do not smoke or light matches near the battery.

Protect your eyes

corrosive sulfuric acid.

• Avoid contact with eyes, skin or

clothing.

Protect from children

Battery acid

• Never swallow the electrolyte.

• Always use safety glasses when

working near the battery.

• Prevent children from getting into

near the battery.

EMERGENCY MEASURES

Read the instructions for use

Explosive gas

• If the electrolyte gets into the eyes, rinse the

eyes with clean water and seek medical help

immediately. If possible, wash your eyes with

water and a clean cloth or sponge also during

the trip to the hospital.

• If the electrolyte gets on the skin,

rinse the affected area thoroughly. If

you feel pain or burning, seek medical

help immediately.

possible for it to penetrate to the

skin, so remove clothing immediately

and follow the instructions above if

– Checking the exterior of the battery

Pole extensions

NOTICE

Chassis cable

u Make sure the engine and all accessories

are switched off before performing

maintenance.

u When checking the battery, first disconnect

the ground cable from the negative terminal

("–" mark) and put it on last.

u Be careful not to short-circuit the tool.

Fastening clip

u Avoid getting any liquid into the battery

when washing it.

Before checking the battery, remove the battery

cover. (See "– Engine Compartment Cover Removal"

on page 361 in Chapter 7–1.)

If the battery is disconnected or discharged, the power

windows and sunroof may not operate automatically when

the battery is reconnected, replaced or recharged, and the

anti-entrapment function will not function properly. In these

cases, you should normalize the operation of the power

windows and sunroof - see "Power windows" on page 38

and "Power sunroof" on page 56 in Chapters 1-2.

Check the battery for corroded or loose terminal

connections or a cracked or loose retaining clip.

a. If the battery is corroded, rinse it with a solution of

warm water and baking soda.

Apply grease to the battery terminals to prevent

further corrosion.

b. If the pole extension connections are loose,

tighten their terminals, but do not overtighten

them.

c. Tighten the retaining clip just enough to hold the

battery firmly in place. Over-tightening the clamp can

damage the battery body.

After checking the battery, replace the battery cover.

– Checking the battery fluid

There are two types of accumulators: maintenance

type and maintenance-free type.

Battery Maintenance Type –

Upper line

Bottom line

Check the fluid level using the fluid level marks on the side of

the accumulator.

Maintenance-free battery type –

Check the battery status using the indicator on the top

of the battery.

LEVEL CHECK USING LINES (MAINTENANCE

BATTERY TYPE ONLY)

The liquid (electrolyte) level must be between the

upper and lower marks.

When checking the fluid level, check all six cells, not just

one or two.

If the level is below the lower line, add distilled water.

(See "REFILLING DISTILLED WATER" on page 389.)
