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 3 303.
Towing the vehicle 3 305.
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.
Caution
Ensure there is adequate
clearance and that there are no
obstructions when adjusting the
suspension height.
The remote control unit is magnetic
and may be fixed to any metal part of the vehicle or stored in its holder.
With the engine running, press the appropriate button for two seconds to
adjust the suspension height.
Indicator light will flash intermittently
while height adjustment is in progress
and illuminates when complete.
If the ignition is switched on with
engine not running, the suspension
height can only be lowered.
Notice
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Pre-programmed settings
Adjusts the suspension height to one
of three pre-programmed positions.
Driving and operating233conditions. 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 98. 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 3 261 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.
Malfunction indicator light 3 98.
AdBlue
General information The selective catalytic reduction is a
method to substantially reduce the
nitrogen oxides in the exhaust
emission. This is achieved by
injecting a Diesel Exhaust Fluid
(DEF) into the exhaust system.
The designation of this fluid is
AdBlue ®
. It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Driving and operating243It 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 kg. 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 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
3 303.
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
3 305.
Towing the vehicle 3 305.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 99.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating255The ultrasonic parking sensors can
be activated or deactivated in the
settings menu in the Info Display.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
The rear parking assist is activated
when reverse gear is engaged. The
front-rear parking assist is activated
when a gear is engaged. Readiness
for operation is indicated by a brief
acoustic signal.
IndicationThe interval between the acoustic
signals becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the signal is continuous.
Additionally, the distance to obstacles is displayed by changing distance
lines in the Info Display.
Deactivation
The system can be deactivated by
pressing =. The LED in the button
illuminates when deactivated.
Depending on version, the system
can also be deactivated in the
settings menu in the Info Display.
Manual deactivation
The system must be deactivated
before towing or if the sensors are
damaged.
Automatic deactivation
The system will automatically be
deactivated when:
● the vehicle speed is above 6 mph
● selector lever in N
● depending on version, when the vehicle is stationary for more than
approx. 5 seconds and an
obstacle is detected
Fault
If the system detects an operating
fault, a continuous acoustic alarm will sound for approx. 3 seconds. Consult
a workshop to have the cause of the
fault remedied.
264Driving and operatingTrailer 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.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 3 315.
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
3 314.
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.
