Climate control1199Warning
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 vehicle
occupants to feel drowsy.
Demisting and defrosting
● Press V. Activation is indicated
by illumination of the LED in the
button.
● Set fan to the desired speed.
Air recirculation mode 4 is
automatically switched off.
Cooling A/C switches on.
● Switch on heated rear window RÜ .
To switch off window demisting and defrosting, press V again,
press AUTO , adjust fan speed or air
distribution switch.
Activated demisting and defrosting
may inhibit autostops. Stop-start
system 3 126.Air vents
Adjustable air vents At least one air vent must be open
while the cooling A/C is on.
To open and close the vents, turn the
horizontal adjuster wheel to the left or right.
Open air vents when air distribution switch is set to M or L.
The air supply is increased by
switching on the fan.
Control the air temperature at the side
air vents by adjusting the temperature
control switch.

120Climate control
Direct the flow of air by tilting and
swivelling the slats.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen, door
windows and in the front and rear foot wells.
The area underneath the front seats
must be kept clear, to allow air flow to
the rear passenger foot well.Maintenance
Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter Cabin air filtration A particle filter cleans the cabin air
from dust, soot, pollen and spores.
Page 123 of 225
Climate control121Active carbon filter
In addition to the particle filter the active carbon filter reduces odours.
Air conditioning regularoperation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
week, 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
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

Refrigerant R-134a contains
fluorinated greenhouse gases.

Driving economically Fuel economy mode
Fuel economy mode is a function that optimises fuel consumption. It affects,
e.g., engine power and torque,
acceleration and gear shift indication.
Manual transmissionActivation
Press s on the instrument panel;
LED in the button illuminates to
indicate activation.
Page 125 of 225

Driving and operating123Deactivation
Press s again; LED in the button
extinguishes.
Stop-start system 3 126.
Automatic transmission
Activate fuel economy mode to allow
the transmission to adapt gearshift
patterns, improving the vehicle's fuel
economy.
Activation
In automatic mode, press s.
Control indicator s illuminates in
the instrument cluster 3 89.
The settings of certain electronic
systems are adapted to reduce fuel
consumption:
● The engine reacts less quickly to
the accelerator pedal.
● Automatic upshift points occur sooner and downshift points
occur later.
● The transmission locks itself to the engine at cruising speeds, to
improve efficiency and increase
power and torque.
● The fuel supply is automatically cut-off more quickly during
vehicle deceleration. Overrun
cut-off 3 126.
Do not use fuel economy mode whilst towing, e.g. a trailer.Deactivation
Press s again; control indicator
s 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 will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 126.

124Driving and operatingPedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
SteeringCaution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
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.
Electric power steering Electric power steering does not havepower steering fluid. Regular
maintenance is not required.
Note
If the steering wheel is turned until it
reaches the end of its travel, and is
held in that position for an extended
period of time, power steering assist
may be reduced. If used for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
If power steering assist is lost due to
a system malfunction, the vehicle can
be steered but may require increased
effort. Seek the assistance of a
workshop.
Control indicator 2 3 86.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
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 of the
battery.

Steering 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.
Starting the engine
Manual transmission: operate clutch
and brake pedals.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Diesel engines: turn the key to
position ON for preheating until
control indicator ! extinguishes
3 87.
Turn key briefly to position START
and release. Key returns
automatically to position ON.
Before restarting or to switch off the engine, turn key back to LOCK.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 10 seconds before
repeating starting procedure.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises. Drive at a moderate speed,
especially in cold weather, until
normal engine operating
temperatures have been reached.
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Stop-start system 3 126.

126Driving and operatingStarting the vehicle at low
temperatures
In extremely cold temperatures, i.e.
below -20 °С, it may be necessary to
crank the engine for up to
30 seconds for it to start.
Turn key to position START and hold
until engine starts. Start attempts
should not last longer than
30 seconds. If engine does not start, wait 10 seconds before repeatingstarting procedure.
Ensure the engine oil is of the correct viscosity, the correct fuel is used,
vehicle services are performed
regularly and the battery is sufficiently
charged.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Overrun cut-off
The fuel supply is automatically cut-
off during overrun, i.e. when the
vehicle is driven with a gear engaged
but accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is depressed. A vehicle battery sensor
ensures that an Autostop is only performed if the vehicle battery is
sufficiently charged for a restart.
Activation
The stop-start system is available as soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing s. The
deactivation is indicated when the
LED in the button extinguishes.
Fuel economy mode 3 122.
Autostop If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal
● set the lever to neutral
● release the clutch pedal
