Radio remote control
synchronisation
After replacing the battery, unlock the
door with the key in the lock. The radio
remote control will be synchronised
when you switch on the ignition.
Memorised settings
When locking the vehicle 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
remembered when 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
on the driver's person. Press the Start/Stop button. The
ignition
is switched on. The electronic
immobiliser and steering wheel lock
are deactivated.
To start the engine depress the brake
and clutch pedals then press and hold
the Start/Stop button.
With automatic transmission, only
start with the vehicle 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 vehicle
Never 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.
Fuel
and engine oil consumption may
be higher during the running-in
period.

Driving and operating
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 3 220.
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 because of 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
3 208.
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 equipment Caution
When operating without a trailer,
remove the coupling ball bar.
