114Driving and operatingParking9Warning
■ Do not park the vehicle on an
easily ignitable surface. The
high temperature of the exhaust system could ignite the surface.
■ Always apply parking brake without pressing release button.Apply as firmly as possible on a
downhill slope or uphill slope.
Depress foot brake at the same
time to reduce operating force.
■ Switch off the engine.
■ If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards
the kerb.
Lock the vehicle 3 20 and activate the
anti-theft locking system 3 28 and
anti-theft alarm system 3 28.

Remote control
116Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by illumination of control
indicator A 3 80. Seek the
assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 132, 3 185 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Driving and operating121
It is possible to use the Laden mode
in both manual and automatic
modes.In both cases, the gearshifting
patterns are adapted automatically
for carrying an increased payload.
Activation
Press the kg button.Control indicator
kg is shown in the transmission
display.The transmission will then
select optimized gearshift patterns.
Deactivation
The Laden mode is switched off by:
■ pressing the kg button again,
■ turning off the ignition.
Kickdown If the accelerator pedal is pressedpast the pressure point, the
transmission shifts to a lower gear
depending on engine speed.Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode.Without
kickdown this automatic shift is not
effected in manual mode.Fault
In the event of a fault, control indicator
W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with
care and anticipation.
Have the cause of the fault remedied
by a workshop.
Interruption of power
supply The clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 171.
If the cause of the fault is not a discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the drive wheels raised off the ground
3 174.
Towing the vehicle 3 174.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 81.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
134Driving and operating
When refuelling is complete, replace
the fuel filler cap and turn it clockwise.
Close the fuel filler flap.
Fuel filler cap
Only use genuine fuel filler caps. Diesel-engined vehicles have special fuel filler caps.
Fuel consumption - CO 2-
Emissions
For the values specific to your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
General information The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation
715/2007 692/2008 A, taking intoconsideration the vehicle weight in running order, as specified by the
regulation.
The figures must not be taken as a
guarantee for the actual fuel
consumption of a particular vehicle.
Additional equipment may result in
slightly higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and
towing tips In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.
Driving and operating135
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 3 201.
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
3 182.
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.
136Driving 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) 3 125.Auxiliary features
