synchronisation After replacing the battery, unlock the
door with the key in the driver's door
lock. The radio remote control will be
synchronised when you switch on the
ignition.
Memorised settings
Whenever the vehicle is locked the
last settings are automatically saved
specifically for the used key:
■ Electronic climate control,
■ Info-Display,
■ Infotainment system,
■ Instrument panel illumination.
The saved settings are automatically
used next time that key is used for
unlocking.Open&Start system
Makes operation of the following
possible without the use of the
mechanical key
■ Central locking system,
■ Anti-theft locking system,
■ Anti-theft alarm system,
■ Power windows,
■ Ignition and starter.
The electronic key simply needs to be in the driver's possession.
Press the Start/Stop button. The
ignition is switched on. The
immobiliser and steering wheel lock
are deactivated.
To start the engine press and hold the
Start/Stop button whilst applying both
the brake and clutch pedals.
Automatic transmission: the engine
can only be started with the selector
lever in P or N.
The engine and the ignition are
switched off by pressing the
Start/Stop button again. The vehicle
must be stationary. The immobiliser is
activated at the same time.

Control of the vehicleNever coast with engine not
running
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Diesel particle filter 3 128.

148Driving and operating
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1300 kg a speed of 80 km/h must not be
exceeded; the use of a stabiliser is
recommended.
If the trailer starts snaking, drive more slowly, 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 3 206.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle 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 sea
level. Since engine power decreases
as altitude increases due to the air becoming 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
3 198.
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 (75 kg) 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.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 90 kg and the gross vehicle weight
rating by 75 kg. If the permissible rear
axle load is exceeded, a maximum
speed of 100 km/h applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
