146Vehicle careBrake fluid9Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be between
the MIN and MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use high-performance brake
fluid approved for the vehicle.
Brake and clutch fluid 3 178.
Vehicle battery
The vehicle battery is located in the
engine compartment.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the vehicle battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to vehicle battery
discharge. Disconnect the clamp from
the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
The anti-theft alarm siren must be deactivated as follows: Switch theignition on then off, disconnect the
vehicle's battery within 15 seconds.
Battery discharge protection 3 105.

Vehicle care147Replacing the vehicle batteryNotice
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
In vehicles with stop-start system,
ensure the correct battery is used
when replacing the vehicle battery.
We recommend that you have the
vehicle battery replaced by a
workshop.
Stop-start system 3 116.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.
9 Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
Jump starting 3 170.
Warning label
Meaning of symbols: ● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the vehicle battery.

Vehicle care155Electrical system
Fuses Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● on the right of the engine compartment, next to the vehicle
battery
● in left-hand drive vehicles; on the
left-hand side of the instrument
panel or, in right-hand drive
vehicles; on the right-hand side
of the instrument panel, behind a
cover
Before replacing a fuse, turn off the
respective switch and the ignition.
There are different types of fuses inthe vehicle.
Depending on the type of fuse, a
blown fuse can be recognised by its
melted wire. Do not replace the fuse until the cause of the fault has been
remedied.
It is advisable to carry a full set of
fuses.
Some functions are protected by
several fuses. Fuses may also be
inserted without existence of a
function.
Notice
Not all fuse box descriptions in this
Owner's Manual may apply to your
vehicle. Refer to the fuse box label,
where fitted.
Fuse extractor
Use a fuse extractor to remove fuses.
Page 158 of 203
156Vehicle care
To help in replacing fuses, a fuse
extractor may be used.
Place the fuse extractor on the
various types of fuse from the top or
side, and withdraw fuse.
Engine compartment fuse
box
The fuse box is on the right of the
engine compartment, next to the
vehicle battery.
To remove the protective cover and
access the fuses, remove the two
screws (see illustration).

164Vehicle careAlways use fine mesh chains that addno more than 10 mm to the tyre tread
and the inboard sides (including chain
lock).
Do not exceed 30 mph when tyre
chains are fitted.9 Warning
Damage may lead to tyre blowout.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that is at tyre's sidewall cannot be repairedwith the tyre repair kit.
9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first or reverse gear.
The tyre repair kit may be located
under the front seat, in the glovebox,
or on the right side of the load
compartment behind a cover.
1. Take the tyre repair kit from the vehicle.
2. Remove the compressor.
3. Set the compressor upright near the tyre.
4. Unscrew valve cap from defective
tyre.
5. Screw the flexible filler hose onto the tyre valve.
6. The switch on the compressor must be set to J.
7. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the vehicle
battery, we recommend running
the engine.

170Vehicle care3.Position the replaced spare wheel
onto the bracket ensuring correct
alignment of the locating pin.
4. Secure spare wheel by tightening two bolts using the wheel wrench.
Have the defective tyre renewed or
repaired as soon as possible.
Directional tyres
If possible, fit directional tyres such
that they roll in the direction of travel.
The rolling direction is indicated by a
symbol (e.g. an arrow) on the
sidewall.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
Do not start with quick charger.
A vehicle with a discharged battery
can be started using jump leads and
the battery of another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the vehicle
battery with eyes, skin, fabrics and painted surfaces. The fluid
contains sulphuric acid which can
cause injuries and damage in the
event of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen battery
before connecting jump leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster battery with the same voltage (12 V). Its capacity
(Ah) must not be much less than
that of the discharged vehicle
battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.
Page 173 of 203

Vehicle care171● The vehicles must not come intocontact with each other during
the jump starting process.
● Apply the parking brake, transmission in neutral.
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged vehicle battery.
3. Connect the black lead to the negative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
one minute.
3. Allow both engines to idle for approx. three minutes with the
leads connected.4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.
