Driving and operating149
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
When measuring the vertical coupling
load, ensure the drawbar of the
loaded trailer is at the same height as it will be when the trailer is coupled
with the towing vehicle loaded. This is
particularly important for trailers with
tandem axle.
Rear axle load
When the trailer is coupled and the
towing vehicle is fully loaded
(including all occupants), the
permissible rear axle load (see
identification plate or vehicle
documents) must not be exceeded.
National regulations regarding
maximum speeds for vehicles towing
a trailer must be observed.Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment with
detachable coupling ball bar The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
Fitting the coupling ball bar
Remove sealing plug from the hole for
the coupling ball bar and stow it in the load compartment.
Confirm that the colour marking on
the lever is red.

Wheels 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.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.
Tyres of size 215/70 R 16 are
recommended as winter tyres.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
If winter tyres are installed that have
not been approved for your vehicle,
Electronic Stability Control (ESC)
system performance may be affected3 139. Seek the assistance of a
workshop regarding availability of
approved winter tyres.
If winter tyres are in use, the
temporary spare wheel may still be
fitted with a summer tyre. Vehicle
driveability could be affected,
especially on slippery road surfaces.

Tyre pressureCheck 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.
Use the valve cap key to make
unscrewing the valve caps easier.
The valve cap key is located on the
inside of the tank flap.
Tyre pressure 3 210.
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.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
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 3 205.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 210.
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 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.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring system The tyre pressure monitoring system
checks the pressure of all four wheels
once per minute when vehicle speed
exceeds a certain limit.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. If
wheels without sensors are mounted,
the tyre pressure monitoring system
is not operational.
Vehicle care179
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 recommended inflation
pressure 3 210.
Low tyre pressure conditionA detected low tyre pressure
condition is indicated by control
indicator w 3 89.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 210.
When the system detects a
malfunction, w will flash for approx.
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When w is illuminated, the system
may not be able to detect or signal low tyre pressure as intended.Tyre pressures in Info-Display
The current tyre pressures can be
shown in the menu item Tyres in the
Board Computer menu. Press the
BC button on the Infotainment system
and select the menu item.
The tyre pressure monitoring system
automatically detects the vehicle
load. A corresponding message may appear on the Info-Display if
inconsistent tyre pressures are
detected. In some versions, the
message is displayed in abbreviated
form.
182Vehicle careTread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended that the tread depth of the tyres on
one axle should not vary by more than
2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels. Ensure that the direction
of rotation of the wheels is the same
as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
If wheel rims of a different type are to
be installed, the wheel nuts may also
need to be changed. We recommend you consult a workshop.
Wheel covers Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
