154Driving and operatingstart 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 audiblewarning 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, the
Driving and operating155shift 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 drivingprogrammes
Winter mode VActivate 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.
156Driving and operatingDeactivation
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.Interruption of power supply
The clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 217.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the
drive wheels raised off the ground
3 219.
Towing the vehicle 3 219.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 you depress the
brake pedal firmly. You need to use considerably more force for this. The
braking distance is extended. Seek the assistance of a workshop beforecontinuing 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.

Traction Control system The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control

166Driving and operatingActivation
The system is automatically active
when the ignition is switched on.
Functionality
When driving in the speed range
mentioned above and a risk of
collision with the vehicle ahead is
imminent, l will flash and a warning
chime sounds.
The indicator light l and the chimes
stop when the system detects that a
collision is not imminent anymore.
Just before the imminent collision, the system brakes automatically to
reduce the impact speed of the
collision or prohibit a crash.9 Warning
Do not rely on the system to brake
the vehicle. Active emergency
braking will not brake outside of its
operating speed range and only
responds to detected vehicles.
Deactivation and re-activation
Active emergency braking can be
deactivated with the vehicle
stationary and the ignition switched
on:
Toggle through the Driver Information Centre with the buttons on the right
stalk tip until message AEBS
ACTIVE appears.
To deactivate the system, press and
hold one of the two buttons for
approx. 3 seconds. Message AEBS
DEACTIVATED is displayed and l
illuminates in the instrument cluster until system is re-activated again.
To re-activate the system, press and hold one of the two buttons for

We recommend to deactivate the
system in the vehicle personalisation
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 damaged
Conditions for re-activation

● the gear lever is not in neutral
● parking brake is not activated
● vehicle is not cornering
