Important safety notes G
WARNING
During the charging process, a battery
produces hydroge ngas. If a shor tcircuit
occurs or sparks are created, the hydrogen
gas can ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
R Never place metal objects or tools on a
battery.
R It is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and
disconnecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running.
Disconnecting the starter battery !
Switch off the engine and remove the key
fro mt he ignition lock before you loosen or
disconnectt he terminal clamps. You may
otherwise destroy electronic components
such as the alternator.
Always disconnectt he starter battery in the
battery case in the driver's footwell first.
! Always disconnectt he battery in
the order described below. Never swap the
terminal clamps. You may otherwise
damage the vehicle electronics. Battery

Loosen the bolts holding retainer 0026, which
prevents the battery from moving around. X
Pull retainer 0026upwards.
X Slide the battery from its anchorage in the
direction of travel.
X Fold the bar of the battery upwards and
remove the battery from the battery case.
Installing the starter battery X
Insert the battery into the battery case.
X Fold down the bar of the battery.
X Slide the battery into its anchorage in the
opposite direction to the direction of travel.
X Insert retainer 0026.
X Tighten the bolts on retainer 0026which
holds the battery in place.

X
Recharge the removed battery. Observe
the notes in the operating instructions for
your battery charger.
X Install the battery. Observe the notes on
reconnecting the battery.
i If batteries are no tbeing used, you should
charge them once a month.
It is also possible to charge the starter
battery using the jump-starting connection
point in the engine compartment
(Y page 267). Care
! Dirty battery clamps and battery surfaces
cause leak currents which lead to the
batteries discharging.
! Do not use cleaning agents containing
fuel. Cleaning agents containing fuel
corrode the battery housing.
! If dirt gets into the battery cell, battery
self-discharge will increase and the battery
may be damaged.
The following points on battery care must be
observed:
X Regularly chec kthe battery terminals and
the fastening of the negative cable to the
chassis to ensure that they are firmly
seated.
X Always keep the battery terminals and
battery surfaces clean and dry.
X Lightly grease the undersides of the battery
terminals with acid-resistant grease.
X Only clean the batteries when the caps are
screwed on.
Otherwise, dirt could get into the battery
cells.
X Unscrew the caps and clean blocked
breathers with a suitable tool such as a
piece of wire.
If you do not unscrew the caps for cleaning,
there is a risk of short circuit. The breathers in the caps and the cell
ventilation tubes must be open. Otherwise,
gas cannot escape.
X Only clean the battery casing with a
commercially available cleaning product. Care
Notes on care
G
WARNING
If you use openings in the bodywork or
detachable parts as steps, you could:
R slip and/or fall
R damage the vehicle and cause yourself to
fall.
There is a risk of injury.
Always use secure climbing aids, e.g. a
suitable ladder.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked. Care
