Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
3 years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance checkNote
Refrigerant R-134a may contain
fluorinated greenhouse gases with a global warming potential of 1430.
Front air conditioning system is filled
with 0.58 kg and has a CO 2
equivalent of 0.83 tonnes, the front
and rear air conditioning system in
Combi variants is filled with 1.1 kg
and has a CO 2 equivalent of
1.57 tonnes and the front and rear air
conditioning system in Bus variants
is filled with 1.7 kg and has a CO 2
equivalent of 2.43 tonnes.
Depending on vehicle, information
regarding air conditioning refrigerant
appears on a label located in the
engine compartment.

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.
If the ignition is switched on with
engine not running, the suspension
height can only be lowered.
Note
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 operating233l:lowered positionk:normal positionj:raised positionCaution
If an obstacle is detected while
raising or lowering, the
suspension height is returned to the normal position after a delay.
This does not guarantee damage- free operation. Ensuring sufficient
clearance and freedom from
obstacles is the responsibility of the driver.
Manual settings
Manual adjustment can only be
performed when the vehicle is
stationary.
Select by pressing h for 2 seconds,
then R to raise, or S to lower.
To exit, press any of the pre-
programmed buttons.
Note
Obstacle detection is not available
during manual adjustment.
When a certain low speed is
exceeded or when the ignition is
switched off, height adjustment is deactivated automatically and the
suspension height is returned to the
normal position.
Service mode
When the vehicle is stationary, press
i for 5 seconds to put the vehicle into
service mode. The indicator light will
illuminate.
When service mode has been
activated, the air suspension master
switch must be turned off.
To exit service mode, press i again
for 5 seconds.
Fault
If a fault is detected, i will flash
intermittently. If service mode has been activated and there is a fault, h,
S and R will flash simultaneously.
Have the cause of the fault remedied
by a workshop.Engine exhaust9 Danger
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
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

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

Driving and operating255pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper
blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
Additionally, warning lights l and
j illuminate at the same time.
When the system detects that its
function is not available, warning light l or j illuminates and stays on.
Additionally, a message in the Driver Information Centre appears. The
system may be temporarily disrupted
(for example: radar or camera
obscured by dirt, mud, snow etc.). In
this case, park the vehicle and switch
off the engine. Clean the windscreen
area around the camera and the
detection zone of the radar in the front bumper. When the warning lights and
messages still appear after starting
the vehicle again, seek the
assistance of a workshop.Parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The parking assist measures the
distance between the vehicle and
obstacles behind and, if available, in
front of the vehicle. It informs and
warns the driver by giving acoustic
signals.
The system consists of four ultrasonic parking sensors in the rear bumper
and, if available, four ultrasonic
parking sensors in the front bumper.
