Jump-starting
Before starting the engine
If
necessary,
the engine can be started by con­
necting it to the battery of another vehicle.
If the engine fails to start because of
a
dis­
charged battery, the vehicle battery can be
con­

nected to the battery of another vehicle to start
the engine. Suitable jump leads are required.
Both vehicle batteries must be rated at 12 V. The
capacity (Ah) of the booster battery should not
be significantly lower than that of the discharged
battery.
Jump leads
The jump Leads must be heavy enough to carry
the starter current. Refer to the details given by
the manufacturer.
Only
use
jump leads with insulated battery
clamps.
Positive cable - usually red.
Negative cable - usually black.
WARNING
- When it is discharged the vehicle battery
can freeze at temperatures around 0°C. A
frozen vehicle battery must first be thawed
out before connecting the jump leads - risk
of explosion and chemical burns! After
jump-starting the vehicle, drive to a quali­
fied workshop without delay and have the
vehicle battery checked.
- The engine compartment is a potentially
hazardous area and working here can lead
to serious injuries. Before carrying out any
work in the engine compartment please
read and observe the warnings
*page
295.
- Incorrect handling of the jump leads may
result in the vehicLe battery exploding (risk
of serious injury). Please observe the follow­
ing rules to minimise the risk of injury:
- The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive terminal
must not touch metal parts of the vehicle:
this can cause short circuiting.
- Position the jump leads in such a way that
they cannot come into contact with any
moving parts in the engine compartment.
- Do not lean over the vehicle battery - risk of
chemical burns!
- The screw plugs on the battery cells must be
screwed in firmly.

A WARNING
Never attempt to repair a fuse or replace a
blown fuse by fitting a fuse with a higher am­
pere rating. This could damage the electrical
system - risk of fire!
© CAUTION
If a newly replaced fuse blows again after a
short time, the electrical system must be
checked by a qualified workshop as soon as
possible.

- Unassigned fuse locations are not shown in
the tables below.
- Some of the items of equipment listed in
the tables below are only fitted on certain
models or are optional extras.
