Driving and operating231Restart of the engine by the stop-start system
If one of the conditions for an
Autostop is not fulfilled anymore or
the vehicle starts to move, the engine
may be restarted automatically by the
stop-start system.
An automatic engine restart may not
be possible if a door or the bonnet is
open.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
If the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Fault
If the LED illuminates in deactivation
button ) without first being pressed
to deactivate the system, there is a
fault in the stop-start system and it is
deactivated. A corresponding
message also appears in the Driver
Information Centre 3 105.
Seek the assistance of a workshop.Parking9 Warning
● 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 brake
pedal 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.
● 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 3 316 or the
vehicle documents.
232Driving and operatingFor 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 3 304.
Towing the vehicle 3 306.
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.

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.
234Driving and operatingconditions. 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 3 262 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 99.
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.
242Driving and operatingStarting the engine
Depress the brake pedal when
starting the engine. If the brake pedal
is not depressed, T illuminates in the
transmission display and the engine
cannot be started.
When the brake pedal is depressed,
the transmission automatically shifts
to N (neutral). "N" appears in the
transmission display and the engine
can be started. There may be a slight delay.
Selector leverAlways move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.N:neutralD/M:switch between automatic and manual mode

Starting off
When the engine is started, the
transmission is in automatic mode.
Depress the brake pedal and move
the selector lever towards + to
engage first gear.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the brake pedal is released. To
start off quickly, release the brake
pedal and accelerate immediately
after engaging a gear.
In automatic mode the transmission
shifts to other gears automatically,
dependent on driving conditions.
To engage manual mode, move the
selector lever towards D/M. The
current gear will appear in the
transmission display.
To engage first gear, depress brake
pedal and move selector lever
towards + or -. Shift to a higher or
lower gear by moving selector lever to + or -. Gears can be skipped by
moving the selector lever repeatedly
at short intervals.
Stopping the vehicle In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped.
In R, reverse gear remains engaged.
When stopping on gradients, engage parking brake or depress the brake
pedal. To prevent overheating of the
clutch, an intermittent audible
244Driving and operatingIt 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
3 304.
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
3 306.
Towing the vehicle 3 306.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 3 100.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
254Driving and operatingThe indicator light l and the chimes
stop when the system detects that a
collision is not imminent anymore.
Just before the imminent collision, the
system brakes automatically to
reduce the impact speed of the
collision or prohibit a crash.9 Warning
Do not rely on the system to brake
the vehicle. Active emergency
braking will not brake outside of its
operating speed range and only
responds to detected vehicles.
Deactivation and re-activation
Active emergency braking can be
deactivated with the vehicle
stationary and the ignition switched
on:
Toggle through the Driver Information
Centre with the buttons on the right
lever until message Active braking
appears.
To deactivate the system, press and
hold one of the two buttons for
approx. 3 seconds. l illuminates in
the instrument cluster until system is
re-activated again.
To re-activate the system, press and hold one of the two buttons for
approx. 3 seconds. l disappears.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when the vehicle is being towed
● before using an automatic car wash with ignition switched on
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
Conditions for re-activation
The Active emergency brake system
can only be re-activated if:
● the gear lever is not in neutral
● parking brake is not activated
● vehicle is not cornering
System limitations In some cases, the active emergency
braking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
