Checking and refilling levels
WARNING
Always be aware of the danger of injury and
chemica l
burns as well as the risk of accident
or fire when working on the battery and the
electrical system:
● Wear eye protection. Protect your eyes,
skin and clothing fr
om acid and particles con-
taining lead.
● Battery acid is extremely corrosive. Wear
protective glo
ves and eye protection. Do not
tilt the batteries. This could spill acid through
the vents.
● Rinse battery acid from eyes immediately
for severa
l minutes with clear water. Then
seek medical care immediately. Neutralise
any acid 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 b
attery 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 bu
l
b is changed, you need only switch
off the light.
● Deactivate the anti-theft alarm by unlock-
ing the vehic
le before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicle on-bo
ard network, disconnect first
the negative cable and then the positive ca-
ble.
● Switch off all electrical devices before re-
connecting the batt
ery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Never charge a frozen battery, or one which
has th
awed. 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 batt
ery.
● Never use a defective battery. This could
cause an exp
losion. Replace a damaged bat-
tery immediately.
● For vehicles with the battery in the luggage
compartment: Chec
k that the battery gas
ventilation hose is securely attached. CAUTION
● Never dis c
onnect the battery if the ignition
is switched on or if the engine is running. This could damage the electrical system or
electronic
c
omponents.
● 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 lon
g 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 sw
itched 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.
