156Driving and operating
Do not operate accelerator pedal.
Press and release Engine Start/Stop:
an automatic procedure operates the
starter with a short delay until the
engine is running, see Automatic
Starter Control.
Before restarting or to switch off the engine when vehicle is stationary, press Engine Start/Stop once more
briefly.
During an Autostop, the engine can
be started by depressing the clutch
pedal 3 157.
Emergency shut off during
driving If the engine needs to be switched offduring driving in case of emergency,
press Engine Start/Stop for longer
than 2 seconds or press twice briefly
within 5 seconds.9 Danger
Switching off the vehicle engine
during driving may cause loss of
power support of brake and
steering systems. Assistance
systems and airbag systems are
disabled. Lighting and brake lights will extinguish. Therefore powerdown the engine and ignition while
driving only in case of vehicle
emergency.
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 .
Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3
or to hold Engine Start/Stop pressed.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
■ Clutch pedal not operated (manual transmission).
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission).
■ Timeout occurred.
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.
Driving and operating167
General
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol R with a number below it
is indicated when gearshifting is
recommended for fuel saving
reasons.
Shift indication appears only in
manual mode.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increases
engine speed to quickly bring the
catalytic converter to the required
temperature.■ The automatic neutral shift function
automatically shifts to idling when
the vehicle is stopped with a
forward gear engaged and the
brake pedal is pressed.
■ When SPORT mode is engaged, the vehicle shifts at higher engine
speeds (unless cruise control is
on). SPORT mode 3 174.
■ Special programmes automatically adapt the shifting points when
driving up inclines or down hills.
■ When starting off in snowy or icy conditions or on other slippery
surfaces, the electronic
transmission control selects a
higher gear automatically.
Kickdown
If the accelerator pedal is pressed
down completely in automatic mode,
the transmission shifts to a lower gear depending on engine speed.Overheat protection
In the event of transmission-
overheating due to high outside
temperatures or sporty driving style, the torque and the maximum speed of
the engine can be temporarily
reduced.
Fault
In the event of a fault a vehicle
message is displayed in the Driver
Information Centre. Vehicle
messages 3 120.
The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.
Only the highest gear is available.
Depending on the fault, 2nd gear may also be available in manual mode.
Shift only when vehicle is stationary.
Have the cause of the fault remedied
by a workshop.
Driving and operating169Caution
It is not advisable to drive with thehand resting on the selector lever.
Gear shift indication 3 107.
Drive systems
All-wheel drive
The All-wheel drive system enhances
driving characteristics and stability,
and helps to achieve the best
possible driveability regardless of
ground surface. The system is always active and cannot be deactivated.
The torque is distributed steplessly
between the wheels of the front and rear axle, depending on the driving
conditions. Additionally the torque
between the rear wheels is distributed
depending on the surface.
For optimum system performance,
the vehicle's tyres should not have
varying degrees of wear.
If a service message is displayed in
the Driver Information Centre, the
system may have limited functionality
(or be completely disabled in some
cases, i.e. the vehicle switches to
Front-wheel drive). Seek the
assistance of a workshop.
Towing the vehicle 3 264.Brakes
The brake system comprises two independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 106.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating175
■ Antilock Brake System (ABS) withcornering brake control (CBC)
■ Automatic transmission
SPORT mode
The settings of the systems are
adapted to a sportier driving style:
■ Damping of shock absorbers reacts
more stiffly to provide better contact with the road surface.
■ The engine reacts more quickly to the accelerator pedal.
■ Steering support is reduced.
■ Engine torque of All-wheel drive is distributed more to the rear axle.
■ Shift points of automatictransmission occur later.
■ Depending on the instrument cluster the colouring of the display
will be adapted.
TOUR mode
The settings of the systems are
adapted to a comfort driving style:
■ Damping of shock absorbers reacts
more softly.
■ Accelerator pedal reacts with standard settings.
■ Steering support is in standard mode.
■ Engine torque of All-wheel drive isdistributed mainly to the front axle.
■ Shift points of automatic transmission occur in a comfort
mode.
NORMAL mode
All settings of the systems are
adapted to standard values.
Drive mode control
Within each manually selected driving mode SPORT, TOUR or NORMAL,
the Drive Mode Control (DMC)
detects and analyses continuously
the real driving characteristic,
responses by the driver, and the
active dynamic state of the vehicle. If
necessary, the control unit of DMC
automatically changes the settings
within the selected driving mode or,
when recognising greater variations,
the driving mode is changed for the
length of variation.
If, for example, NORMAL mode is
selected and DMC detects a sporty
driving behaviour, DMC changes
several settings of the Normal mode
210Driving and operating
When the system recognises an
unintended lane change, the control indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ); the LED in the button
extinguishes.
At speeds below 35 mph the system
is inoperable.
Fault
The lane departure warning system
may not operate properly when:
■ The windscreen is not clean.
■ There are adverse environmental conditions, e.g. heavy rain, snow,
direct sunlight or shadows.
The system cannot operate when no
lane marking is detected.Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 279. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
