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.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Notice
Pollen filter is only fitted to vehicles
with air conditioning system.
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.Service
For optimal cooling performance, it is recommended that the climate control
system be checked annually, 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 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.

116Driving 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.

Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
If the electronic key is not inside the
vehicle, a corresponding message
appears in the Driver Information
Centre (DIC) 3 90.
Notice
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 92 and a message in the
Driver Information Centre (DIC)
3 91).

118Driving and operating● 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 20.
Central locking system 3 23.
Electronic key system 3 22.
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 88.
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 3 119.
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.Idle speed control
To increase the idle speed, press theswitch. After a few seconds the
function will be activated.
The function will be deactivated
when:
● The clutch pedal is depressed.
● The accelerator pedal is depressed.
● Vehicle speed is above 0 mph.
● Control indicator F, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.

120Driving and operatingActivation
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.
If the below conditions are not
fulfilled, an Autostop is prohibited and
control indicator \ illuminates in the
instrument cluster 3 89.
Deactivation
Deactivate the stop-start system
manually by pressing Î. LED in the
button illuminates to indicate
deactivation and a corresponding message appears in the Driver
Information Centre (DIC) 3 90.
If deactivated manually, it is possible to reactivate the stop-start system by
pressing Î again.
Vehicle messages 3 91.
Notice
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 (DIC) 3 90.
Idle speed control 3 118.
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.
An Autostop is indicated when Ï
illuminates in the instrument cluster
3 89.
During an Autostop, heating and
brake performance will be
maintained. However, brake assist is
not available 3 130.
Caution
The steering assist may be
reduced during an Autostop.

140Driving and operatingGuide lines (3, 4, 5) are used together
with the fixed lane display (2) and
indicate the distance behind the
vehicle.
The guide line intervals are as
follows:3 (red):30 cm4 (yellow):70 cm5 (green):150 cm
Settings
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
system manual for further
information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged
for approx. 5 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.
