146Vehicle careOnly use high-performance brake
fluid approved for the vehicle.
Brake and clutch fluid 3 177.
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.
Battery discharge protection 3 105.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this paragraph may lead to
a temporary deactivation 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 volts when using a battery
charger. Otherwise the vehicle
battery might 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 3 169.

points illustrated.
3. Renew bulb, ensuring it engages correctly.
4. Reinstall lamp assembly.
Instrument panel

Have bulbs replaced by a workshop.Electrical 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.
Page 157 of 201
Vehicle care155It 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.
Note
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.
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).

5. Screw the flexible filler hose ontothe 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.8. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
9. All of the sealant is pumped into the tyre. Then the tyre is inflated.
Tyre pressure 3 190. When the
correct pressure is obtained,
switch off the compressor.
10. If a pressure of 1.5 bar is not obtained within five minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for five minutes. If a pressure of
1.8 bar is still not obtained within
five minutes, the tyre is too badly
damaged. Seek the assistance of
a workshop.
Do not run the compressor longer
than 20 minutes.
11. Detach the tyre repair kit.
12. Remove any excess sealant using a cloth.
13. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
14. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
10 km (but no more than
ten minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.

1. Unscrew two bolts using thewheel wrench and remove spare
wheel from bracket. Vehicle tools
3 158.
2. Change the wheel.
3. 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.
Page 172 of 201

170Vehicle care● A discharged vehicle battery canalready 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 Volts). 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.● The vehicles must not come into contact 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.
