-Do not interchange the positive and neg­
ative cables .
- When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen 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 ca ­
ble .
- Before performing any work on the elec ­
trical system , switch off the engine and
ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­
ing 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! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables - this could start a fire!
- Never charge a fro zen or a thawed-out
battery. It could explode! If a battery has
fro zen, then it must be replaced. A dead
battery can freeze over at 32°F (O°C) .
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion ! Al­
ways replace a damaged battery .
A WARNING
California Proposition 65 Warning:
Checking and Filling 225
-Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en­ gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven ,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.

226 Check ing and F illin g
• Only now plug the mains lead for the charg ­
ing equipment into the wall outlet and turn
iton ¢_& .
• M ake sure the ch arging rate is not o ver
30 amp s / 14. 8 Volt.
• When the battery is fully charged: Turn the
charging equ ipment off and remove the
mains lead from the wa ll outlet .
• Now remove the clamps for the charg ing
equipment.
• Close the red cover on the posit ive po le.
• Close the hood

A discharged batte ry can fr eez e at tempera­
tures of on ly 32 F
0 (0 °C). A llow a frozen bat­
tery to thaw completely before attempting to
charge it¢ .&. . However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma­
tion and can leak battery acid.
Batt ery cha rg ing (Ma ximum cha rging rate
of
30 a mp s/ 14.8 Vo lt )
When charging at low voltages (e .g. w ith a
t ric kle char ger ), the battery cables do not
have to be d isconnected first . The battery
caps should
not be opened when charging a
battery.
It is not necessary to remove the battery from
the luggage compartment, and it is also not
necessary to disconnect the cables .
Fas t ch arg ing th e batter y (charging r ate
above 14.8 Volt s)
For technical reasons do not use a battery
charger that uses voltage g reate r than
14 .8 Volts to charge your veh icle's battery .
A WARNING
-
Charging a batte ry can be dangerous.
- Always follow the operating instructions
provided by the batte ry charger manu­
facturer when charging your battery.
- Never charge a frozen battery .
It may ex­
plode because of gas t rapped in the ice.
Allow a frozen batte ry to thaw o ut first.
- Do not reuse batteries which were fro­
zen. The batte ry housing may have cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
tr ical spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive.
- To reduce the danger of explosion, never connect or d isconnect charger cables
while the charger is operat ing .
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent techn ic ian with the proper equip­
ment.
- Battery acid that may sp ill dur ing charg­
i n g should be washed off with a solut ion
of warm water and baking soda to neu­
tralize the ac id.
(D Note
Never use a fast charger as a booster to
start the eng ine . Th is w ill seriously dam­
age sens it ive e lectronic components, such
as contro l units, re lays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the elect ri­
ca l ene rgy th rougho ut yo ur vehicle
¢page 193. The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional electrical en­
ergy is ava ilable once again after you have
changed the battery, we recommend that you
install batteries of the same type and manu ­
facture only (the same as those installed at
the time your veh icle was de livered) . Specifi­
cations are listed on the batte ry housing. Your
a utho rized deale r must code the batte ry in
the energy management system to enab le you
to use the energy management functions cor -
rect ly after replacing the battery.

2 7 4 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Using jump start cables
Connect the jump start cables in the exact or­
der described below.

The battery is located to the left in the engine
compartment.
Do not jump start a frozen or
thawed battery¢
,A in Starting with Jumper
cables on page
273! Replace the battery. The
procedure for connecting jump start cables
that is described next is designed to help
jump start your vehicle.
Vehicle with drained battery:
.. Read the following carefully ¢ page 2 73
.. Set the parking brake and place the selector
lever in the P position.
.. Turn the ignition and electr ical equipment
off in both vehicles.
Connecting the negative terminal(·) to
the negative terminal (-) (black)
.. To reach the battery terminals, flip the bat­
tery cover cap to the side¢
fig. 194.
l. Clamp the end of the red jump start cable
to the terminal (!)¢
fig. 195 on the dead
battery @¢0
in Starting with Jumper
cables on page 273.
2. Clamp the other end of the red jump start
cable to the terminal @on the charging
battery @.
Connect NEGATIVE (-) to NEGATIVE (-)
(black)
3. Clamp the black end of the jump start ca­
ble
preferably at the ground point, or on
the negative terminal@on the charging
battery @.
4. Clamp the other black end of the jump
start cab le
only on the ground point@
on your vehicle @¢(D.
5. Route the jump start cables so they can ­
not get caught in the moving parts in the
engine compartment .
Starting the engine
6. Start the engine in the vehicle giving the
charge and let it run at idle.
7 . Start the engine in the vehicle with the
dead battery and wait two to three mi­ nutes until it "runs smoothly" .
8.
If the engine does not start: Stop the
starting procedure after
10 seconds and
then repeat it after approximately
30 sec­
onds .
9 . In the vehicle that is being jump started,
switch the heater fan and rear window de­
froster on to reduce any voltage peaks
that may occur when disconnecting the
jumper cables. The headlights must be
switched off .
10. With the engines running, remove the ca­
bles in
reverse order of the way they were ..,.
