Cooling
The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
press A/C OFF to switch the cooling
system off, thus saving fuel.
" A/C OFF " appears in the display.

Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
To return to automatic mode, press
u or AUTO .
Rear heating system
If the engine is switched off, the rear
compartment can be heated by the
additional heating, through low level
vents.
By programming values using the
control panel, the user can adjust the
time, day and temperature settings.
Heating will cease to operate if the
vehicle fuel level drops too low.
During operation, power from the
vehicle battery is used. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
Note
If the rear heating system is
activated while the engine is
running, an Autostop will be
inhibited.
To ensure efficient performance, the
low level air vents in the rear
passenger compartment must not be
obstructed.

Combi
Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in
use, to prevent ice forming in the
system due to lack of air movement.
Auxiliary heaterCoolant heater
The engine-independent, fuel-
powered coolant heater provides
rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.

Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.

cool.
Maintenance
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 check
142Driving and operating9Warning
Switch off engine and ignition
before exiting the vehicle.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an Autostop
● the rear air conditioning system is
not activated
● the brake vacuum is sufficient
● the self-cleaning function of the diesel particle filter is not active
3 146
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See "Climate control" chapter for
further information 3 120.
Immediately after motorway driving
an Autostop may be inhibited.

Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.Restart of the engine by the driverManual transmission
With the selector lever in neutral,
depress the clutch pedal to restart the
engine.
Note
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.
If the engine does not restart first
time, depress clutch pedal fully again.Manual transmission automated
With the selector lever in position N
(or A/M ) and the parking brake
released, release the brake pedal to
restart the engine.
Engaging reverse gear or depressing
the accelerator pedal may also restart the engine.
The green control indicator Ï will

Note
Only use the designated AdBlue canisters for refilling, to prevent a
topping-up of too much AdBlue.
Additionally, the fumes in the tank

Driving and operating169Conditions 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 emergencybraking 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
pedal 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
lights l or j illuminates and stays
on. Additionally, a message in the
Driver Information Centre appear.
The system may be temporarilydisrupted (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 the vehicle. It
informs and warns the driver by giving acoustic signals.
