134Driving and operatingManual transmission
automated
The manual transmission automated (MTA) permits manual (manual
mode) or automatic gear shifting
(automatic mode), both with
automatic clutch control.
Transmission display
Shows the mode and current gear.
Starting 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
Driving and operating135start 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
136Driving and operatingshift 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 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.
Driving and operating137Deactivation
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
3 193.
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
3 195.
Towing the vehicle 3 195.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 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 88.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating147Deactivation
It is possible to deactivate or
temporarily deactivate the system.

When reverse gear is selected no
acoustic signal will sound, indicating
deactivation.
The function is reactivated by
pressing r again or the next time
the ignition is switched on.
Permanent deactivation
Permanently deactivate the system
by pressing and holding r on the
instrument panel for approx. 3 seconds with the ignition on. Control
indicator in the button illuminates
continuously.
The system is deactivated and will not
operate. When reverse gear is
selected no acoustic signal will
sound, indicating deactivation.
The function is reactivated by
pressing and holding r for approx.
3 seconds.
Fault
If the system detects an operating
fault, a continuous acoustic alarm will sound for approx. 3 seconds when
selecting reverse gear. Consult a
workshop to have the cause of the
fault remedied.Caution
When reversing, the area should
be free from obstacles which could impact on the underside of the
vehicle.
Impact to the rear axle, which may
not be visible, could lead to
uncharacteristic changes in the
vehicle handling. In the event of
such an impact, consult a
workshop.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle in
either the interior mirror, the driver's
sun visor or the Infotainment system
display screen.
9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
148Driving and operatingcamera's field of view, e.g. below
the bumper or underneath the
vehicle, are not displayed.
Do not reverse the vehicle by only looking at the display and checkthe surrounding area behind and
around the vehicle before
reversing.
The camera is typically installed on
the rear doors/tailgate, beneath the
number plate moulding.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Notice
To achieve the optimum visibility, the rear view camera must not be
obscured by dirt, snow or ice.
