Climate control129Press A/C again to switch off 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,
switch off the cooling system for fuel
saving reasons.
Manual air recirculation 4
Press 4 to activate the air
recirculation mode. The LED in the
button illuminates to indicate
activation.
Press 4 again to deactivate
recirculation mode.9 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 from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the occupants to
feel drowsy.
In warm and very humid ambient air
conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.

Air heater
Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Parking heater
The parking heater allows to heat the
vehicle's interior and to ventilate the
vehicle's interior with ambient air.
The operating status of the parking
heater is shown by an indicator with a LED.
● LED illuminates: A timer has been set.
● LED flashes: The system is operating.
The LED is extinguished at the end of
the heating operation or when the
parking heater is stopped using the
remote control.
The parking heater can be
programmed using the Graphic Info
Display / Colour Info Display.
Additionally, the parking heater can
be switched on and off using a remote control.
Notice
The programmed heating /
ventilation is only activated if the
ignition is off and the vehicle is
locked.
If the charging level of the high
voltage battery is below 50%, the
programmed heating / ventilation is
not activated.
If a recurrent heating / ventilation is
programmed and two heating /
ventilation procedures are carried
out without operating the vehicle, the
programmation is deactivated.

9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.

Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler The air conditioning system draws
cooled air into the glovebox through a
noozle.
Move the slider back or forth in order
to enable or disable glovebox cooling.
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 the
outside temperature is too low.
Service For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three 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

Driving and operating141button. Turn the steering wheeluntil the steering wheel lock is
felt to engage.
● For hybrid vehicles, make sure READY is not illuminated in the
instrument cluster.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 213.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
In the event of an accident with airbag deployment, the engine is
switched off automatically if the
vehicle comes to a standstill within a
certain time.
In countries with extreme low
temperatures it may be necessary to park the vehicle without applied
parking brake. Make sure to park the
vehicle on a level surface.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.
Exhaust filter
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The start of saturation of the exhaust
filter is indicated by the temporary
illumination of % or C ,
accompanied by a message in the
Driver Information Centre.

Driving and operating205Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle. If
using non-factory fitted towing
equipment, deactivation of the hands- free tailgate operation may be
required 3 29.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage. E.g. in case of
four bulbs with a power of 5 W each,
the function only detects light outage
when only a single 5 W light remains
or none remain.
Trailers equipped with LED lights are
not suitable for the wiring harness of
this trailer hitch.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ballbar for towing. Always keep the
coupling ball bar in the vehicle to have it on hand if needed.
Driving characteristics and towing tips
Before attaching a trailer, lubricatethe coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce
snaking movements.
During trailer towing do not exceed a
speed of 50 mph. A maximum speed
of 60 mph is only appropriate if an oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle's curb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
recommended.
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 3 266.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle 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 inclines up
to 12%.
The permissible trailer load applies
up to the specified incline and at 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 altitude. The
gross train weight does not have to be

Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.

Vehicle care215Engine coolant
The factory filled coolant provides
freeze protection down to approx.
-37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 254.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
MIN mark. Top up if the level is low.
9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
