beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler The air conditioning system can also
keep 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.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
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 isrecommended 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.
ActivationPress the ECO button. Control
indicator illuminates when activated
and a corresponding message
appears in the Driver Information
Centre 3 84.
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 the ECO button again. Control
indicator extinguishes.
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

Do not accelerate.
Turn the key to position M for
preheating, and hold until control
indicator N extinguishes from the
Driver Information Centre.
Turn key to position D 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 St.
During an Autostop, the engine can be started by depressing the clutch
pedal. Stop-start system 3 111.
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.

112Driving and operating
AutostopIf the vehicle is at low speed or
standstill, activate an Autostop as
follows:
■ depress the clutch pedal
■ shift the selector lever to neutral (manual transmission) or N
(manual transmission automated)
■ release the clutch pedal
The engine will be switched off while the ignition stays on if the required
conditions are met.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and brake performance will be
maintained. Brake assist, however, is
not available 3 123.
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 ambient temperature is not too low
■ the defrosting function is not activated■the climate control system does not
inhibit an Autostop
■ the brake vacuum is sufficient
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See Climate control chapter for
further information 3 96.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.

start off quickly, release the foot brakeand accelerate immediately after
engaging a gear.
In automatic mode the transmission
shifts to other gears automatically,
dependent on driving conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
To engage first gear, depress foot
brake and move selector lever
towards + or -. Shift to a higher or
lower gear by moving selector lever to
+ or -. Gears can be skipped by
moving the selector lever repeatedly
at short intervals.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped.
In R, reverse gear remains engaged.
When stopping on gradients, engage
parking brake or depress the foot
brake. To prevent overheating of the
clutch, an intermittent audiblewarning may sound as a signal to
depress the foot brake or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the foot brake has not
been depressed.
Engine braking Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached.
It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when driving downhill.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking Apply the parking brake. The most
recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the parking brake has not been applied, a
warning chime will sound upon
opening the driver's door.

rear view camera must not be
obscured by dirt, snow or ice.9 Warning
The system is intended as a
reversing aid and does not replace driver vision.
Do not let this feature tempt you
into take risks when reversing.
Failure to use proper care when
reversing may result in damage to
the vehicle, injury, or death.
Always check the outside,
rearview mirrors and glance over
your shoulder before reversing.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.Fuel
Fuel for diesel enginesOnly 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 may affect
your warranty.
Do not use marine diesel oils, heating
oils or entirely plant-based diesel
fuels, such as rape seed oil or bio
