(or A/M ) and the parking brake
released, release the brake pedal to
restart the engine.
Engaging reverse gear or depressing
the accelerator pedal may also restart the engine.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted. If
certain conditions are not fulfilled, a
restart will not take place. Start using
the ignition key.
Starting the engine 3 137.
Driving and operating141Bus
The engine is restarted automatically
when operating the power sliding
door switch on the instrument panel
during an Autostop.
Sliding door 3 30.
Restart of the engine by the stop- start system
If one of the following conditions occurs during an Autostop, the
engine may be restarted
automatically by the stop-start
system. Control indicator Ï will flash
green in the instrument cluster during an automatic engine restart.
● the vehicle battery is discharged
● the ambient temperature is too low
● the defrosting function is activated
● the brake vacuum is not sufficient
● the brake pedal is operated repeatedly
● the vehicle starts to moveAn automatic engine restart may not
be possible if a door or the bonnet is
open.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during restart might be noticeable.
If the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Fault
If control indicator Ï illuminates
yellow, or the LED illuminates in
deactivation button Î without first
being pressed to deactivate the
system, there is a fault in the stop-
start system 3 103. A corresponding
message also appears in the Driver
Information Centre 3 104.
Seek the assistance of a workshop. Warning chimes 3 106.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 parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards the kerb.
Driving and operating153Starting the engine
Depress the brake pedal when
starting the engine. If the brake pedal
is not depressed, T illuminates in the
transmission display and the engine
cannot be started.
When the brake pedal is depressed,
the transmission automatically shifts
to N (neutral). "N" appears in the
transmission display and the engine
can be started. There may be a slight delay.
Selector leverAlways move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.N:neutralA/M:switch between automatic and manual mode
The transmission display
shows "A" when in automatic
mode.R:reverse gear
Engage only when vehicle is
stationary. The transmission
display shows "R" when
reverse gear is engaged.+:shift to a higher gear.-:shift to a lower gear.
Starting off
When the engine is started, the
transmission is in automatic mode. Depress the brake pedal and move
the selector lever towards + to
engage first gear.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the brake pedal is released. To
start off quickly, release the brake pedal and accelerate immediately
after engaging a gear.
In automatic mode the transmission
shifts to other gears automatically,
dependent on driving conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
To engage first gear, depress brake
pedal and move selector lever
towards + or -. Shift to a higher or
lower gear by moving selector lever to + or -. Gears can be skipped by
moving the selector lever repeatedly
at short intervals.
Stopping the vehicle In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped.
In R, reverse gear remains engaged.
When stopping on gradients, engage
parking brake or depress the brake
pedal. To prevent overheating of the
clutch, an intermittent audible
154Driving and operatingwarning may sound as a signal to
depress the brake pedal or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the brake pedal has not
been depressed.
Engine 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.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake. The most
recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the
parking brake has not been applied, a
warning chime will sound upon
opening the driver's door.
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, theshift is not executed. This prevents
the engine from running at too low or too high an engine speed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
Electronic driving programmes
Winter mode V
Driving and operating155Activate the Winter mode if you have
problems starting off on a slippery
road surface.
Activation
Press V. Control indicator V is shown
in the transmission display. The
transmission switches to automatic
mode and the vehicle starts off in a
suitable gear.
Deactivation
The Winter mode is switched off by:
● pressing V again
● turning off the ignition
● switching to manual mode
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning may
sound. In such cases, depress the
brake pedal, select "N" and apply the parking brake to allow the clutch to
cool down.Laden mode kg
It is possible to use the Laden mode
in both manual and automatic modes. In both cases, the gearshifting
patterns are adapted automatically
for carrying an increased payload.
Activation
Press kg. Control indicator kg is
shown in the transmission display.
The transmission will then select
optimized gearshift patterns.
Deactivation
The Laden mode is switched off by:
● pressing kg again
● turning off the ignition
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear
depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with
care and anticipation.
Have the cause of the fault remedied
by a workshop.
Driving and operating1579Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, j , R and
C illuminate, the ABS and ESC are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the assistance of a workshop.
Have the cause of the fault remedied
by a workshop.

in the following cases:
● when the vehicle is being towed
● before using an automatic car wash with ignition switched on
● if the windscreen has been damaged close to the camera
● if the front bumper has been damagedConditions for re-activation
The Active emergency brake system can only be re-activated if:
● the gear lever is not in neutral
● parking brake is not activated
● vehicle is not cornering
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is
limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
