Entry lighting Welcome lighting
Some or all of the following lights are
switched on for a short time by
unlocking the vehicle with the radio
remote control:
● headlights
● puddle lights
● interior lights
The number of activated lights
depends on the surrounding light
conditions.
The lighting switches off immediately
when the ignition is switched on.
Starting off 3 98.
This function can be activated or
deactivated in the vehicle
personalisation.
Vehicle personalisation 3 76.The following lights will additionally
switch on when the driver's door is
opened:
● illumination of some switches
● Driver Information Centre
● door pocket lights
Exit lighting The following lights are switched on
when the ignition is switched off:
● headlights
● interior lights
● centre console lighting
They will switch off automatically after
a delay. This function works only in
the dark.
Vehicle locator lighting
This function allows to locate the
vehicle, e.g., in weak lighting
conditions using the remote control.
The headlights come on and the turn
lights flash for 10 seconds.

Peripheral lighting allows you to
switch on the position lights, low
beam and number plate lighting using the remote control.
Press D on the remote control to
switch on peripheral lighting.
Press D a second time to switch off
peripheral lighting.
Battery discharge protection
To prevent discharge of the vehicle
battery when the ignition is switched
off, some interior lights are switched
off automatically after some time.
102Driving and operatingStarting 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 .
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.
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.
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.
The system is ready to operate when
the LED in the button D is not
illuminated. To activate the system
when the system is deactivated,
press D.
If the stop-start system is temporarily not available and the button D is
pressed, the LED in the button
flashes.
Deactivation
Deactivate the stop-start system
manually by pressing D. The
deactivation is indicated when the
LED in the button illuminates.
Driving and operating103AutostopVehicles with manual transmission
Activate an Autostop as follows:
● Set the selector 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 steep inclines.
Indication
An Autostop is indicated by control
indicator n.
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.
● The engine exhaust temperature is 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.
Climate control 3 89.
Immediately after higher speed
driving an Autostop may be inhibited.
New vehicle running-in 3 98.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
104Driving and operatingPower 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 transmission
Depress the clutch pedal without
depressing the brake pedal to restart
the engine.
Vehicles with automatic transmission The engine is restarted in the
following cases:
● brake pedal released while the selector lever in position D or M
● brake pedal released or selector lever in position N when selector
lever is moved to position D or
M
● selector lever moved to position RRestart 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:
● stop-start system manually deactivated
● driver's seat belt unfastened and driver's door opened
● engine temperature too low
● charging level of vehicle battery below a defined level
● brake vacuum not sufficient
● vehicle driven at least at walking speed
● climate control system requests engine start
● air conditioning 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.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake.
● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P. On an uphill
slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P . Turn the front wheels
towards the kerb.
● Close the windows.
● Switch off the engine.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
