130Driving and operatingRear view camera
The camera is typically installed
under the number plate moulding with a display monitor fitted to the driver's
sun visor.
Functionality
The rear view camera system
enables the driver to view the rear of
the vehicle in the display monitor
whilst reversing.
The system can be activated or
deactivated by selecting the
Start/Stop button located on the right-
hand side of the display monitor.
The remaining buttons on the monitor enable the user to select source
AV1 or AV2 and adjust the brightness
and contrast of the display monitor.
To achieve the optimum visibility, the
rear view camera must not be
obscured by dirt, snow or ice.9 Warning
The system is intended as a
reversing aid and does not replace
driver vision.
Do not let this feature tempt you
into take risks when reversing.
Failure to use proper care when
reversing may result in damage to
the vehicle, injury, or death.
Always check the outside,
rearview mirrors and glance over
your shoulder before reversing.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Fuel
Fuel for diesel enginesOnly use diesel fuel that complies
with EN 590. The fuel must have low
sulphur content (max. 10 ppm).
Equivalent standardised fuels with a
biodiesel (= FAME according to
EN14214) content of max. 7% by
volume (like DIN 51628 or equivalent
standards) may be used.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils or entirely plant-based diesel
fuels, such as rape seed oil or bio
Driving and operating133
If the trailer starts snaking, drive moreslowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 198.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %.
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 metres above sealevel. Since engine power decreases as altitude increases due to the airbecoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 % for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving on roads with slight inclines (less than 8 %, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 179.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especially
in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.In the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded (including
all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
signals.
134Driving and operating
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working,keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic stability
program (ESP) 3 124.Auxiliary features
Power take-off

138Vehicle care
Pull out the dipstick, wipe it clean,insert it to the stop on the handle, pull
out and read the engine oil level.Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
Caution
Do not allow the engine oil level to drop below the minimum level!
We recommend the use of the same
type of engine oil that was used at the
last change.
The engine oil level must not exceed the maximum mark MAX on the
dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
A stabilization of the engine oil
consumption will not take place until
the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than
0.5 litres every 600 miles after this
running-in period, consult a
workshop.
Capacities 3 197, Engine oil level

Fuses
Data on the replacement fuse must match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
■ on the left-hand side of the instrument panel, behind the trim
panel.
■ in the engine compartment located below the coolant expansion tank.
Before replacing a fuse, turn off the respective switch and the ignition.
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. Consult a workshop.
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
manual may apply to your vehicle.
When inspecting the fuse box, refer to the fuse box label.
156Vehicle careWheels and tyres
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Tyres Factory-fitted tyres are matched to
the chassis and offer optimum driving
comfort and safety.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the maximum speed
sticker in the driver's field of view.Tyre designations

Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressures 3 198. Always inflate
tyres to the pressures shown on the
label on the driver's door frame.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect 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 3 198.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
Vehicle care157
The driver is responsible for correct
adjustment of tyre pressure.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.
Rear-wheel drive, with twin rear
wheels When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoring
system
The Tyre Pressure Monitoring
System (TPMS) 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.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Each tyre, including the spare, should
be checked monthly when cold and
inflated to the inflation pressure
recommended on the tyre pressure
label.
Tyre pressures in display
The current tyre pressures can be
shown in the Driver Information
Centre 3 84.
With the vehicle stationary, press
button on end of wiper lever
repeatedly until the tyre pressure
menu is displayed.
158Vehicle care
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 82 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 198.
After inflating, driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting low pressure. Check tyre pressure.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w flashes for
several seconds then illuminates continuously together with control
indicator A 3 80 and a
corresponding message appears in
the Driver Information Centre.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for these wheels. For the further three
wheels, TPMS remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.
Driver Information Centre 3 84.
Vehicle messages 3 85.Puncture
A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 80 and a corresponding message
appears in the Driver Information
Centre.
Tyre pressure 3 198, Tyre repair kit
3 161, Spare wheel 3 166, Wheel
changing 3 164.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Therefore it is important to check tyre pressure with
cold tyres.
