Battery charging
Starting the engine requires a well charged battery.
Fig. 237 Engine
compa rtment : Connec
tor s for charger and
jumper cables
Always read and heed all WARNINGS below=> & and => &
in "Working on the battery" on
page 309.
- Turn off the ignition and all electrical consumers.
- Make sure the area is well ventilated when you charge the
battery.
- Open the hood :::::,
page 296.
-Open the red cover on the positive pole =>fig. 23 7.
- Connect the charger connectors according to the instruc-
tions to the
jump start bolts . (Bolts under the red cover=
"positive", Bolts with hex head
= "negative") .
- Only now plug the mains lead for the charging equipment
into the wall outlet and turn it on =>& .
-Make sure the charging rate is not over 30 amps/14.8
Volt.
- When the battery is fully charged: Turn the charging
equipment off and remove the mains lead from the wall
outlet.
Vehicle OP-eration
-Now remove the clamps for the charging equipment.
- Close the red cover on the positive pole.
- Close the hood :::::,
page 297.
A discharged battery can freeze at temperatures of only O 0C. Allow a
frozen battery to thaw completely before attempting to charge it
~ & .However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
When charging at low voltages (e.g. with a trickle charger ), the
battery cables do not have to be disconnected first . The battery caps
sho uld
not be opened when charging a battery.
It is not necessary to remove the battery from the luggage com part·
ment.
Fast charging the battery (charging rate above 14.8
Volts)
For technical reasons do not use a battery charger that uses voltage
greater than 14.8 Volts to charge your vehicle's battery .
& WARNING
Charging a battery can be dangerous.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery.
• Never charge a frozen battery. It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first.
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze.
• Charge the battery
in a well ventilated area. Keep away from
open flame or electrical spark. Do not smoke. Hydrogen gas gener-
ated by the battery is explosive. •

Emergency situations
General
This chapter is intended for trained emergency crew s and working
pe rsonnel who have the necessary tool s and equipment to perform
the se operation s. •
Starting by pushing or towing
0 Note
Yo ur vehicle is equipped with an automatic t ransmission . Conse
quently, the engine ca nnot be started by push ing or tow ing .•
Starting with jumper cables
I f necessary, the engine can be started by connectin g it to
the bat tery of another vehicle.
If the eng ine shou ld fa il to start because of a discharged or weak
battery, the battery can be connected to t he battery of
another
veh icle, us ing a pair of jumper cables to start the eng ine .
Jumper cables
Use only jumper cables of sufficiently large cro ss section to carry the
sta rter cur rent safely . Refer to the m an ufa ct ur er's specificat ions.
Use only j umpe r cab les with
insulated te rm inal clamps wh ich are
distinct ly marked :
plus(+) cable in most cases colored red
minus (-) cable
in most cases colored b lack .
& WARNING
Batterie s contain el ectricity, acid, and gas . Any of the se can cause
very serious or fatal injury. Follow the inst ructions below for safe
handling of your vehicle 's battery.
• Always shield your eyes and avoid leaning over the battery
whenev er po ssible .
• A discharged battery can freeze at temperatures just below
32 °F (0 °C ). Before connecting a jumper cable, you must thaw the
frozen battery completely, otherwise it could explode.
• Do not allow battery acid to contact eyes or sk in . Flush any
contacted area with water immedi ately .
• Improper use of a booste r battery to start a vehicle may cause
an explosion .
• Vehicle batteries generate e xplosive gases. Keep sparks, flame
and lighted cigarettes away from batterie s.
• Do not try to jump start any vehicle with a low acid level in the
battery.
• The voltage of the booster battery must also have a 12-Volt
rating. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cau se
an e xplosion and personal injury.
• Never charge a frozen battery . Gas trapped in the ice may cause
an explosion.
• Never charge or use a battery that has been frozen. The battery
case may have be weakened .
• Use of batteries of different voltage or substantially different
capacity (Ah) rating may cause an explosion and injury . The
capacity (Ah) of the booster battery should not be lower than that
of the discharged battery. .,_

& WARNING (continued)
• Before you check anything in the engine compartment, always
read and heed all WARNINGS~
page 286, "Engine compart
ment".
0 Note
• Applying a higher voltage booster battery will cause expensive
damage to sensitive electronic components, such as control units,
relays, radio, etc.
• There must be no electrical contact between the vehicles as other
wise current could already start to flow as soon as the positive(+)
terminals are connected.
[I] Tips
• The discharged battery must be properly connected to the
vehicle's electrical system . When jump starting or charging the
battery, never connect the negative ground cable to the battery nega
tive post because the battery manager system must be able to detect
the battery's state of charge. Always connect the negative ground
cable to the negative ground post of the battery manager control
unit. •
Vehicle OP-eration
Use of jumper cables

Starting the engine
- Start the engine of the vehicle with the booster battery.
Run the engine at a moderate speed.
- Start engine with discharged vehicle battery in the usual
manner.
- If the engine fails to start: do not keep the starter
cranking for longer than 10 seconds. Wait for about
30 seconds and then try again.
- With engine running, remove jumper cables from both
vehicles in the exact
reverse order.
- Close the red cover on the positive pole.
The battery is vented to the outside to prevent gases from entering
the vehicle interior. Make sure that the jumper clamps are well
connected with their
metal parts in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed all warnings and instructions of the jumper cable manufacturer. If
in doubt, call for road service.
• Jumper cables must be long enough so that the vehicles do not
touch.
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.
• Before you check anything in the engine compartment, always
read and heed all WARNINGS~
page 286, "Engine compart
ment".
0 Note
Improper hook-up of jumper cables can ruin the generator.
• Always connect POSITIVE(+) to POSITIVE( +), and NEGATIVE( -)
to NEGATIVE(-) ground post of the battery manager control unit.
• Check that all screw plugs on the battery cells are screwed in
firmly . If not, tighten plugs prior to connecting clamp on negative
battery terminal.
• Please note that the procedure for connecting a jumper cable as
described
above applies specifically to the case of your vehicle being
jump started. When you are giving a jump start to another vehicle, do
not connect the negative(-) cable to the negative(-) terminal on the
discharged battery©~
page 353, fig. 263. Instead, securely
connect the negative(-) cable to either a solid metal component that
is firmly bolted to the engine block or to the engine block itself.
If the
battery that is being charged does not
vent to the outside, escaping
battery gas could ignite and explode! •
