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.

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.

160Vehicle careIncorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 182.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 190.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressures.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
10 kPa (0.1 bar) for a 10 °C
temperature increase. This must be
considered when warm tyres are
checked.
Tyre pressure monitoring
system
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
The tyre pressure monitoring system sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Tyre pressure chart 3 190.

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.

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.

Vehicle care1714. 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.Towing
Towing the vehicle
Release the cap by carefully lifting
with a screwdriver. To prevent
damage, it is recommended to place
a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 158.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
Caution
The towing eye must only be used for towing and not for recovering
the vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
Note
If neutral cannot be selected on
vehicles with manual transmission
automated (MTA), the vehicle must
only be towed with the drive wheels
raised off the ground.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
