Practical advice
Jump-starting
Jump-starting
If it is no longer possible to start the engine
with the emergency start button, another
vehicle or an external battery with jump
leads can assist you.
Observe the following points:
Jump-starting may only be performed
when the engine and catalytic convert-
er are cold.
Do not start the engine if the battery
has frozen. Let the battery thaw first.
Only use batteries with a nominal volt-
age of 24V for jump-starting.
Only use jump leads that are protected
against polarity reversal and which
have an adequate cross-section and in-
sulated battery terminal clamps.
