5 Nm -arrow-.

Note

♦

The tightening torque for the additional battery terminals is 6

Nm.

♦

The battery poles cannot be lubricated.

♦

The battery pole terminals can only be connected manually

and should not be forced, thus avoiding damage to the battery

case.

♦

After reconnecting the battery, make an inspection of the ve‐

hicle equipment (radio, clock, electric convenience system,

power window drive, etc.) as per the repair manual and/or in‐

struction manual.

♦

It is essential that you make a visual inspection of the external

condition and the battery connections before any measure‐

ments.

WARNING

Please follow the warning notes and safety rules for lead and

acid batteries, represented by symbols on the battery tag.

Warning notes and safety rules for lead and acid batteries
1 - Fires, sparks, open flame and smoking are prohibited:
– Avoid sparks and electrostatic discharges when handling ca‐

bles and electrical devices;

– Avoid short circuits (never lay a tool on top of a battery).
2 - Please wear protective goggles.
3 - Keep children away from acid and batteries.
4 - Recycling:
– Dispose of old batteries at a battery collection center (suppli‐

er).

5 - Never discard old batteries in domestic waste!
6 - Risk of explosion:
– A highly explosive mix of oxy-hydrogen gas is produced when

charging batteries.

7 - Follow the instructions mentioned on the battery, in the elec‐

trical system repair manual and in the operation manual.
8 - Danger of chemical corrosion.
– The battery acid is highly corrosive, therefore wear protection

Battery - check the charge capacity

Note

The vehicle must have remained turned off for at least 2 hours.

4.10.1

Check the charge indicator “inspection

glass” at Delivery inspection

Carry out a visual inspection on the charge indicator “inspection

glass” -arrow-.
The Charge indicator “inspection glass” informs the battery

charge condition.

Note

♦

Since the inspection glass is located on a single battery cell,

the indication only refers to this cell. A precise assessment on

the battery condition is only possible through a test to check

the battery charge capacity 

⇒ page 43

 .

♦

Specially when a battery is recharged, that is, even when the

battery is charged during driving, air bubbles can form under

the inspection viewing glass. These bubbles change the color

indication in the inspection viewing glass.

♦

The inspection viewing glass may be located at various posi‐

tions on the battery.

– Before making the visual inspection, tap lightly and carefully

with a screwdriver handle on the charge indicator glass

-arrow- so that air bubbles do not interfere with the inspection.

This way, any air bubbles that could influence the indicator are

eliminated and dissipate.
The color indication of the “inspection glass” becomes more ac‐

curate. There are three possible indications:
– Green → the battery is sufficiently charged.
– Black → no charge or insufficient charge, the battery must be

charged (repair measure). For battery recharging procedures

– Colorless or yellow → the battery must be replaced (repair

measure).

test device operation instructions.

The claws must have good contact with the battery poles.
– The charge current varies and the battery capacity must be

adjusted on the test device. ⇒  Battery test device operation
