Checking and Filling
-Do not interchange the positive and nega
tive cables .
- When working on the battery, be sure not to
short-circuit the terminals with tools or oth
er metal objects. This would cause the bat
tery to heat up very quickly, which could
lead to damage or explosion and personal
injury .
- When a battery is charged, it produces hy
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys
tem, disconnect the negative ground cable .
- Before performing any work on the electri
cal system, switch off the engine and igni
tion as well as any electrical equipment. The
negative cable on the battery must be dis
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off. Re
connect the positive cable first and then the
negative cable . Never interchange the ca
bles -this could start a fire!
- Never charge a frozen or a thawed-out bat
tery. It could explode! If a battery has fro
z en, then it must be replaced . A discharged
battery can freeze over at 32°F (O°C).
- Make sure the vent hose is always attached
to the opening on the side of the battery .
- Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related acces
sories contain lead and lead compounds,
232
chemicals known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling.
(D Note
- Do not disconnect the vehicle battery when
the ignition is switched on or when the en
gine is running, otherwise , you will damage
electronic components in the electrical sys
tem .
- If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing", otherwise it
will be damaged and will then have to be re placed.
Battery charging
Starting the engine requires a well charged battery .

A discharged battery can freeze at temperatures
of only 32 °F (0 °C). Allow a frozen battery to
thaw completely before attempting to charge it
c::> ,& . However, we recommend not using a
thawed battery again because the battery casing
can be cracked due to ice formation and ca n leak
battery acid.
B attery ch arging (Maximum charging rate of
30 amps /14.8 Volt )
When charging at
Low voltages (e.g. w ith a tri ckl e
c har ger ),
the bat tery cables do not have to be
d isconnected first. The ba ttery caps shou ld
not
be opened when charg ing a battery .
I t is not necessary to
remove the batte ry from
t he luggage compa rtment.
F a st charging the b attery (charging rate
above 14.8 Volts )
F or technica l reasons do not use a battery charg
e r that uses voltage greater than 14.8 Vol ts to
charge your veh icle's batte ry.
A WARNING
Charging a batte ry can be dangerous.
- Always fo llow the oper ating instructions
provided by the battery charge r manufactur
er when charging your battery.
Checking and Fillin g
-Never charge a frozen battery. It may ex
plode because of gas trapped in the ice . Al
low a frozen battery to thaw out first.
- Do not reuse batteries wh ich were frozen.
The battery housing may have cracked and
weakened whe n the battery froze.
- Charge the battery in a well ventilated area. Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas generat
ed by the batte ry is explosive .
- To reduce the danger of explosion, never
connect or d isconnect charger cab les wh ile
the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a competent
technician w ith the proper eq uipment.
- Battery acid that may sp ill dur ing cha rging
should be washed
off with a solut ion of
warm water and baking soda to neutralize the acid .
@ Note
Never use a fast charger as a booster to start
the eng ine . T his w ill ser iously damage sensi
tive elec tronic components, s uch as control
units, relays, radio, etc., as we ll as the battery
cha rger.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipmen t
battery.
Intelligent energy management in your vehicle is
r esponsible for distributi ng the elect rical energy
t h ro ugh out your vehicle
c::> page 196. T he intelli
gen t energy management system w ill keep the
engi ne battery charged better then vehicles with
out this system . To make s ure the additiona l elec
trical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu
facture on ly (the same as those installed at the
t ime you r vehicle was del ivered) . Specificat ions
are listed on the battery hous ing . Your autho r-
ized dea ler must code the battery in the ene rgy ..,.
