slats of the air vents. Risk of
damage and injury in case of an
accident.

Climate control129ServiceFor 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
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

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.

132Driving and operatingStarting 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 3 136.
Diesel particle filter 3 140.
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: Steering
wheel 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.

134Driving and operatingThese functions stop working when
the driver's door is opened and the
vehicle is locked.
Note
Always take the electronic key with you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 104 and a message in the
Driver Information Centre 3 103
when the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
● Fault in electronic key.
● Electronic key out of reception range.
● Battery voltage too low.
● Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
Battery replacement 3 22.
Central locking system 3 26.
Electronic key system 3 24.
Starting the engine
Manual transmission: operate clutch.
Do not accelerate.
Diesel engines: turn the key to
position 2 for preheating until control
indicator ! extinguishes in the
instrument cluster 3 100.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Stop-start system 3 136.

Driving and operating137Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated and
cannot be reactivated by pressing
Î . LED in button illuminates to
indicate deactivation and a
corresponding message may
appear in the Driver Information
Centre 3 102.
Idle speed control 3 135.
Depending on version, if the driver's
door is opened or the driver's seat belt
is unfastened, the stop-start system is
deactivated automatically, and the
engine is switched off. Restart engine by pressing START/STOP .
Power button 3 132.
Autostop If the vehicle is at a low speed or at astandstill, activate an Autostop as
follows:
● depress the clutch pedal
● move the selector lever to neutral
● release the clutch pedalThe engine will be switched off while
the ignition stays on if the required conditions are met.
An Autostop is indicated when Ï
illuminates in the instrument cluster
3 101.
During an Autostop, heating and brake performance will be
maintained. Brake assist, however, is
not available 3 148.
Caution
The power steering assist may be
reduced during an Autostop.
If you exit the vehicle while the engine is in an Autostop, a warning chime will
sound and a message " IGNITION
OFF " is displayed in the Driver
Information Centre as a reminder that
the engine is on standby and has not
been switched off.
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 driver's door is closed or the driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the outside temperature is not too
low or too high (e.g. below 0 °C
or above 30 °C)

Driving and operating159The guide line intervals are as
follows:3 (red):30 cm4 (yellow):70 cm5 (green):150 cmSettings
Settings, e.g. brightness, contrast and colours can be changed via the
Infotainment system. The feature
may also be switched off
permanently. Refer to Infotainment
manual for further information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged
for approx. five seconds.
Fault
The rear view camera may not
operate properly when:
● the surrounding is dark
● the sun or the beam of headlights
is shining directly into the camera
lens
● ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth
● the rear doors / tailgate are not closed correctly
● the vehicle had a rear-end accident
● there are extreme temperature changesFuel
Fuel for diesel engines Only use diesel fuel that complies
with EN 590. The fuel must have low
sulphur content (max. 10 ppm).
Equivalent standardised fuels with a
biodiesel (= FAME according to
EN14214) content of max. 7% by
volume (like DIN 51628 or equivalent
standards) may be used.
In countries outside the European
Union, use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and loss of
warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
