Checking and refilling levels
seek medical care immediately. Neutralise
any ac
id splashes on the skin or clothing
with a soapy solution, and rinse off with plen-
ty of water. If acid is swallowed by mistake,
consult a doctor immediately.
●
Fires, sparks, open flames and smoking are
prohibited. When handling cables and electri-
cal equipment, avoid causing sparks and
electrostatic charge. Never short the battery
terminals. High-energy sparks can cause in-
jury.
●
A highly explosive mixture of gases is re-
leased when the battery is under charge. The
batteries should be charged in a well-ventila-
ted room only.
●
Keep children away from acid and batteries.
●
Before working on the electrical system,
you must switch off the engine, the ignition
and all electrical devices. The negative cable
on the battery must be disconnected. When a
light bulb is changed, you need only switch
off the light.
●
Deactivate the anti-theft alarm by unlock-
ing the vehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
●
When disconnecting the battery from the
vehicle on-board network, disconnect first
the negative cable and then the positive ca-
ble.
●
Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
●
Never ch
arge a frozen battery, or one which
has thawed. This could result in explosions
and chemical burns. Always replace a battery
which has frozen. A flat battery can also
freeze at temperatures close to 0°C (+32°F).
●
Ensure that the vent hose is always connec-
ted to the battery.
●
Never use a defective battery. This could
cause an explosion. Replace a damaged bat-
tery immediately.
CAUTION
●
Nev
er dis
connect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
●
Do not expose the battery to direct sunlight
over a long period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
●
If the vehicle is left standing in cold condi-
tions for a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged.
Warning lamp
It lights up
Alternator fault.
The control lamp lights
up when the igni-
tion i
s
switched on. It should go out when the
engine has started running.
If the control lamp lights up while driving,
the alternator is no longer charging the bat-
tery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment
that is not absolutely necessary because this
will drain the battery.
Checking the battery electrolyte level
The electrolyte level should be checked regu-
l
arly
in high-mi
leage vehicles, in hot coun-
tries and in older batteries.

Open the bonnet and open the battery cov-
er at the front ›››
in Safety notes for work
in the en
gine c
omp
artment on page 263
›››
in Symbols and warnings on handling
the b
att
er
y on page 272. For vehicles with
the battery under the spare wheel, open
the rear lid and lift the floor covering. The
battery is located next to the spare wheel.
–
Check the colour display in the "magic eye"
on the top of the battery.
–
If there are air bubbles in the window, tap
the window gently until they disperse.
