Emergency Starting with Jumper
CablesIf the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.The discharged battery
must be correctly connected to the vehicle's elec-
trical system.
fPlease observe the chapter “BATTERY” on
Page 320.
Note
Do not try to start the car by pushing or towing.
Damage to the catalytic converters and other
components of the car may result.
Danger!
Risk of damage and serious personal injury
due to short circuit.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fCarefully ensure that tools or conductive jewel-
ery (rings, chains, watch straps) do not come
into contact with the positive jumper cable or
the positive battery post.
fImproper hook-up of jumper cables can ruin
the alternator.
Danger of caustic burns.
fDo not lean over the battery.Danger of gas explosion.
fImproper use of booster battery to start a ve-
hicle may cause an explosion, resulting in se-
vere personal injuries.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at
14°F (10°C). Before connecting jumper ca-
bles, a frozen battery must be thawed out.

Connecting jumper cablesAlways observe the sequence below:
1. Remove cover A.
2. Open the cap of the positive terminal for jump
starting(+).
3. Attach the positive lead first to the positive
terminal for jump starting (+), then to the posi-
tive terminal of the donor battery.
4. Connect the negative lead first to the negative
terminal of the donor battery, then to the
grounding point for jump starting (–).
+ = Positive terminal for jump starting
– = Grounding point for jump starting5. Run the engine of the donor car at a higher
speed.
6. Start the engine.
An attempted start using jumper cables should
not last more than 15 seconds. Then allow a
waiting period of at least one minute.
7. Disconnect the negative jumper cable from the
ground point for jump starting (–) first, then
from the negative terminal of the donor bat-
tery.8. Disconnect the positive jumper cable from the
positive terminal of the donor battery first,
then from the positive terminal for jump start-
ing (+).
9. Close the cap of the positive terminal for jump
starting (+).
