General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by
a
qualified
workshop
^A-

The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Explanation of warnings on vehicle battery:

m

Wear safety glasses!
Battery acid is extremely corrosive. Wear
protective gloves and safety glasses.

A

Keep open flames, sparks, uncovered
Lights and lit cigarettes away from the
battery!
A highly explosive mixture of gases may

~\
be given off when the battery is under
charge!
Keep children away from batteries and
battery
acid.

A WARNING
Any work on the batteries and electrical sys­
tem in your vehicLe entails a risk of injury and
chemical burns in addition to danger of
acci­

dent or fire. For this reason, you must have
the work carried out by a qualified workshop.

Vehicle battery

The
term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
If the vehicle is not used for long periods
If
you
do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are

using.
This limits the amount of power consumed
and helps to ensure reliable starting even after a
long period
^>page
149. Certain convenience fea­

tures,
such as interior lighting or electric seat ad­
justment, may not be available. These functions
will be restored when you switch on the ignition
and start the engine.
Even though some systems are deactivated auto­
matically, certain electrical equipment continues
to draw current even when the ignition is off. If
the vehicLe is left standing for long periods, this
can result in total battery discharge. If the
vehi­

cle battery is allowed to discharge completely, an
internal
chemicaL
reaction damages the battery
irreparably. To avoid this, the vehicle battery
should be recharged at Least once a month

^>page
303. PLease contact a qualified workshop
if
you
have any questions.
Winter conditions
Cold weather is very hard on the vehicle battery.
The starting capacity may be reduced as a result.
For this reason, you should have the vehicle bat­
tery checked by
a
qualified workshop before the
start of winter.

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.

- Keep sparks, flame and lit cigarettes away
from vehicle batteries: the gases given off
can cause an explosion.
- Do not attach the negative cable to parts of
the fuel system or to the brake pipes.
© CAUTION
- The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected and
the boosting battery could be discharged.
- If the jump leads are not connected correct­
ly this can result in serious damage to the
electrical system of the vehicle.
- The discharged vehicle battery must be
properly connected to the vehicle's electri­
cal system.
- Please note that the method described
be­

low for connecting the leads is intended for
jump-starting your vehicle. If jump-starting
another vehicle, you should not connect the
negative lead (-) to the negative terminal of
the discharged battery, but directly to the
engine block or
a
solid metal part bolted to
the engine block. If the battery of the other
vehicle does not have a gas vent, there is a
risk that
a
mixture of oxygen and hydrogen
gas can accumulate and cause an explosion.

Tow-
start
ing / towing
away
General notes
Some experience is required to tow or tow-start a
vehicle, especially when using a tow-rope. Both
drivers should be familiar with the technique re­
quired for towing. Inexperienced drivers should
not attempt to tow-start or tow away another ve­

hicle.

Do not pull too hard with the towing vehicle and
take care to avoid jerking the tow-rope. When
towing off-road, there is aLways a risk that the
anchorage points may be overloaded.
Tow-bar / tow-rope
It is easier and safer to tow the vehicle with a
tow-bar. You should only use a tow-rope if you do
not have a tow-bar. It is advisable to use a tow-
rope made of elastic synthetic fibre or similarly
elastic material.
Notes on towing vehicles
The vehicle can be towed with a tow-bar or tow-

rope.
When the engine is not running, the
gear­

box will not be adequately lubricated if the
fol­

lowing speed/distance restrictions are not ob­

served:

- The vehicle must not be towed faster than
50 km/h.
- The vehicle must not be towed further than
50 km. •
