Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position P .
Heating functionalities
Notice
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.
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 pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
136Driving and operatingStop-start systemThe 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.
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.
DeactivationDeactivate the stop-start system
manually by pressing Ò. The
deactivation is indicated when the
LED in the button illuminates.
AutostopVehicles with manual transmission
An Autostop can be activated at a
standstill.
Activate an Autostop as follows: ● Depress the clutch pedal.
● Set the lever to neutral.
● Release the clutch pedal.
The engine will be switched off while
the ignition stays on.Vehicles with automatic transmission If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
The engine will be switched off while the ignition stays on.
The stop-start system will be disabled
on inclines of 12% or more.Indication
An Autostop is indicated by control
indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions 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 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.
Driving and operating137● The engine exhaust temperatureis not too high, e.g. after driving
with high engine load.
● The ambient temperature is not too low or too high.
● 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.
Notice
The Autostop may be inhibited for
several hours after a battery
replacement or reconnection.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 119.
If an autostop is temporarily not
available, D flashes green 3 92.
Immediately after driving at a higher
speed an Autostop may be inhibited.New vehicle running-in 3 131.
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 such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to save power.
Restart of the engine by the driver
Vehicles with manual transmissionConventional restart
All engines have conventional restart.
Depress the clutch pedal without depressing the brake pedal to restart
the engine.
On engines with late restart a
conventional restart is only possible
without depressed brake pedal.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 driver's seat belt is unfastened or the driver's door is
opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.
Vehicle care223If using a vehicle wash, comply with
the vehicle 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.
Wax painted parts of the vehicle regularly.
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 four to nine.
Do not use cleaning agents on hot surfaces.
Do not clean the engine compartmentwith 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.
Have the door hinges of all doors
greased by a workshop.
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 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.Plastic body parts must not be treated with wax or polishing agents.
Windows and windscreen wiper
blades
Switch off wipers before handling in
their 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.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Remove dirt residues from smearing
wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
