Electronic stability
program
The Electronic stability program
(ESP® Plus
) improves driving stability
when necessary, regardless of thetype of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
the ignition is switched on and control

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
Page 133 of 209

Driving and operating131
diesel, Aquazole and similar diesel-
water emulsions. Diesel fuels must not be diluted with fuels for petrol
engines.
The flow and filterability of diesel fuels are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.Caution
In case of misfuelling, do not
switch on ignition.
The fuel tank filler neck with bayonet
cap is located on the left front side of
the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the door is opened. Open the fuel filler flap by
hand.
Remove the fuel filler cap by turning
it anti-clockwise.
The fuel filler cap can be hung on the lower hook of the fuel filler flap.
Caution
Wipe off any overflowing fuel
immediately.
When refuelling is complete, replace
the filler cap and turn it clockwise.
Close the fuel filler flap.

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.
Page 136 of 209
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
