122Driving and operatingTurbo 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.
Depending on driving conditions, the
overrun cut-off may be deactivated.
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.On vehicles with manual
transmission, the engine is started automatically as soon as the clutch is depressed.
Activation The stop-start system is available assoon 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 eco. The
deactivation is indicated when the
LED in the button extinguishes.
AutostopVehicles with manual transmission
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.
The engine will be switched off while
the ignition stays on.
Indication
An Autostop is indicated by control
indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Driving and operating123Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
● 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 engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.
● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
'Climate control' chapter for further
information 3 110.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 120.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features, e.g. the rear window
heating, are disabled or switched into
a power saving mode. The fan speed of the climate control system is
reduced to save power.
Restart of the engine by the driverVehicles with manual transmission
Depress the clutch pedal to restart the
engine.When the engine is restarted, control
indicator D in the Driver Information
Centre extinguishes.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in
the Driver Information Centre.
Control indicator - 3 79.
Restart of the engine by the stop- start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.

After having changed defective fuses
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.
Instrument panel fuse box Left-hand drive vehicles
The fuse box is behind the light switch
in the instrument panel. Hold the
handle, then pull and fold down the
light switch.
Right-hand drive vehicles
Vehicle care199If using a car wash, comply with the
car wash manufacturer's instructions.
The windscreen wiper and rear
window wiper must be switched off.
Remove antenna and external
accessories such as roof racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use
an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax painted parts of the vehicle
regularly (at the latest when water no longer beads). Otherwise, the
paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.Unpainted plastic body parts must not
be treated with wax or polishing
agents.
Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with theseparts.
Matt painted decor parts, e.g. mirror
housing cover, must not be polished.
Otherwise these parts would become agleam or the colour would be
dissolved.
Windows and wiper blades Switch off wipers before handling intheir areas.
Use a soft lint-free cloth or chamois
leather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
