142Driving and operating● Close the windows.
● Turn the ignition key to position
0 and remove it. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
Lock the vehicle 3 24 and activate the
anti-theft locking system 3 35 and
anti-theft alarm system 3 36.
Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
Caution
To ensure safe operation of the air
suspension system, do not exceed the maximum permissible gross
vehicle weight rating. Refer to
identification plate 3 228 or the
vehicle documents.
For further information on the air
suspension system, refer to the
operating instructions supplied.
Master switchCaution
The air suspension system must
be switched off when the vehicle is being towed, jump‐started, raised
off the ground or transported.
Do not switch off the air
suspension system when driving.
Jump starting 3 217.
Towing the vehicle 3 219.
The master switch is located on the
lower part of the right-hand door pillar,
behind a trim panel.
Switch on to enable operation and
adjustment of the air suspension
system.
Switch off to put the vehicle into
service mode.
Remote control
When increased ground clearance or improved vehicle access is required,
the suspension can be raised or
lowered using the remote control.
144Driving 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 j 3 99. 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 3 173, 3 230 could
damage the catalytic converter or
electronic components.
Unburnt fuel 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.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.
156Driving and operatingDeactivation
The Laden mode is switched off by:
● pressing kg again
● turning off the ignition
Kickdown If the accelerator pedal is pressed
past 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
3 217.
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
3 219.
Towing the vehicle 3 219.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 beforecontinuing 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 3 100.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating175Trailer 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 the coupling 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.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 3 249.
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 m 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 m 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
3 228.
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.
176Driving and operatingIn 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
lights.
The pitch of the audible warning will
change if a turn 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) 3 160.Auxiliary features
Power take-off
Activation
To activate the power take-off, with
the vehicle stationary and the engine
idling:
● Set the gearshift lever to neutral (vehicles with manual
transmission automated:
selector lever in position N).
● Depress the clutch pedal.
