Control of the vehicle
Never coast with engine not
running
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 systems function during an
Autostop.
Stop-start system 3 111.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Driving and operating113● The brake vacuum is sufficient.
● 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 3 102.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 109.
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

To start off immediately without
depressing the brake pedal, move the selector lever to D or R. D or R will
flash for a short time in the Driver
Information Centre. Accelerate as
long as D or R flashes. The selected
gear is engaged and the vehicle starts moving.
If the accelerator pedal is not
depressed as long as D or R are
flashing in the Driver Information
Centre, no gear is engaged.
Stopping the vehicle In D, first gear is engaged and the
clutch is released when the vehicle is
stopped. In R, reverse gear remains
engaged.
118Driving and operatingEngine 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. Changing into
manual mode is only possible while
the engine is running.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see transmission display) remains
engaged when switching off ignition.
With N, no gear is engaged.Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Manual mode
If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or too high an engine speed. M and the
number of the selected gear will be
flashed, then the current gear is
displayed again..
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.Gear shift indication
The symbol R with a number
alongside it, is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
The adaptive programme tailors
gearshifting to the driving conditions, e.g. greater load or gradients.
Fault
To prevent damage to the manual
transmission automated, the clutch is engaged automatically at high clutch
temperatures.
In the event of a fault, control indicator
g illuminates. Additionally, a

Parking assist
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system has three ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle. The interval between the
sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approx. 40 cm, the sound is
continuous.
Deactivation
The system automatically switches
off when reverse gear is disengaged.
The system might not detect the
obstacle when the vehicle is driven above a 10 km/h.
Fault
