Adjustable air vents At least one air vent must be open
while cooling is on, in order to prevent
the evaporator from icing up due to
lack of air movement.9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Centre air vents
To open or close the centre air vents
and direct the flow of air, tilt the slats
up or down and turn the adjuster
wheel left or right.
Side air vents
To open or close the side air vents, tilt the slats up or down.
Direct the flow of air by rotating the
vents.
Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
Page 132 of 241

130Climate controlRear air ventsDepending on vehicle, additional
adjustable air vents are located in the
rear passenger compartment.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows, in the foot wells and,
depending on vehicle, in the rear
passenger compartment.
Glovebox cooler The air conditioning system can alsokeep the contents of the glovebox
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
Note
Refrigerant R-134a contains
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 is
filled with 0.88 kg and has a CO 2
equivalent of 1.26 tonnes.
Depending on vehicle, information
regarding air conditioning refrigerant
appears on a label located in the
engine compartment.

Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
Page 134 of 241

132Driving and operatingNote
The use of ECO mode may affect the performance of the climate control
system 3 118.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press ECO again. Control indicator
ECO extinguishes in the instrument
cluster.
Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there may be a controlled
reduction in power steering assist and
vehicle speed is reduced.
Stop-start system 3 137.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats which fit properly and are fixed by the retainers on the
driver's side.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.Steering
If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.

Driving and operating133Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
vehicle battery.
Stop-start system 3 137.
Diesel particle filter 3 141.
Ignition switch positions
Turn key:0:ignition off: Some functions
remain active until key is
removed or driver's door is
opened, provided the ignition was on previously1:accessory power mode: Steeringwheel lock released, some
electrical functions are operable,
ignition is off2:ignition is on, diesel engine is
preheating. Control indicators
illuminate and most electrical
functions are operable3:engine start: Release key after
starting procedure beginsSteering wheel lock
Remove key from ignition switch and
turn steering wheel until it engages.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Power button
Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
Page 136 of 241

134Driving and operatingIf the electronic key is not inside the
vehicle, a corresponding message appears in the Driver Information
Centre 3 103.
Note
Do not put the electronic key in the
load compartment during driving, as
this is outside of the detection zone
(indicated by a warning chime at low
speed 3 105 and a message in the
Driver Information Centre 3 104).
Note
In the event the electronic key is kept in the front passenger compartment
and a message appears in the Driver
Information Centre (possibly
accompanied by a warning chime)
indicating that it is out of reception
range, we recommend inserting the
electronic key in the card reader.
Some functions, e.g. Infotainment
system, are available for use as soon
as you enter the vehicle.Accessory power mode
Press START/STOP without
operating clutch or brake pedal to
enable further electrical functions to
be operated.
These functions switch off
automatically after a delay.
Engine start
Operate clutch and brake pedal and press START/STOP . Release button
after starting procedure begins.
If a gear is engaged, the engine can
be started only by operating the clutch pedal and pressing the
START/STOP button.
In some cases, it may be necessary
to move the steering wheel slightly
while pressing START/STOP to
release the steering wheel lock. A
corresponding message appears in
the Driver Information Centre 3 103.
At very low outside temperatures (e.g. below -10 °C) keep the clutch pedal
depressed while pressing
START/STOP until the engine starts.If one of the starting conditions is not
applied, a corresponding message appears in the Driver Information
Centre 3 103.
Vehicle messages 3 104.
Engine stop
Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
With the vehicle stationary, press
START/STOP to stop the engine. The
steering wheel lock is engaged when
the driver's door is opened and the
vehicle is locked.
If the electronic key is not detected, a corresponding message appears in
the Driver Information Centre 3 103.
In this event, press START/STOP for
2 seconds to stop the engine.
Central locking system 3 26.
Retained power off Press START/STOP for more than
2 seconds. The engine is stopped
while some functions, e.g.
Infotainment system, are available for
use for approx. 10 minutes.
