For starting assistance, jump lead cables con-
forming to the standard DIN 72553 are re-
quired (see the cable manufacturer instruc-
tions). The jump lead cable must be at least
2

engines, and 35 mm
(0.054 inches
sel engines.
For vehicles whose battery is not in the en-
gine compartment, the jump leads should
only be connected to the starting assistance
connection points in the engine compart-
ment.
WARNING
Incorrect use of jump leads and incorrectly
jump starting could cause the battery to ex-
plode resulting in serious injury. Please ob-
serve the following rules to minimise the risk
of a battery explosion:
●
The battery providing current must have
the same voltage (12V) and approximately
the same capacity (see markings on battery)
as the flat battery.
Never charge a frozen or recently thawed
●
battery. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
If a battery is frozen and/or has been frozen
●
then it must be replaced.
A highly explosive mixture of gases is re-
●
leased when the battery is being charged. Al-

ways keep lit cigarettes, flames, sparks and
fire far from the battery. Never use a mobile
telephone when connecting and removing the
jump leads.
Charge the battery only in well ventilated
●
areas given that when the battery is charged
by outside assistance, it creates a mix of

●
Jump leads should never enter into contact
with moving parts in the engine compart-
ment.
●
Never switch the positive and negative
poles or connect the jump leads incorrectly.
●
Note the instruction manual provided by
the manufacturer of the jump leads.
CAUTION
To avoid considerable damage to the vehicle
electrical system, note the following careful-
ly:
●
If the jump leads are incorrectly connected,
this could result in a short circuit.
●
The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
