Selector lever
Always move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.
N=neutral positionD/M=switch between automatic (D)
and manual (M) shift mode.
The transmission display
shows either D or M with the
selected gear<=upshifting in manual mode]=downshifting in manual modeR=reverse gear. Engage only
when vehicle is stationary
If selector lever is moved from R to the
left, D is directly engaged.
If selector lever is moved from D to
< or ], manual mode M is selected
and the transmission shifts.
Starting off
Depress the foot brake and move the
selector lever to D/M or R. If D is
selected, transmission is in automatic
mode and first gear is engaged. If R
is selected, reverse gear is engaged.
The vehicle starts to move when the
foot brake is released.
To start-off without depressing the
foot brake, accelerate immediately
after engaging a gear as long as D or
R flashes.
If neither the accelerator nor the
brake pedal are depressed, no gear
is engaged and D or R flashes for a
brief time in the display.
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.
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. Changing into
manual mode is only possible while
the engine is running or during an
Autostop.

142Driving and operating
Rocking the vehicleRocking 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.Tyre pressure monitoring
system
To start the sensor matching process of the tyre pressure monitoring
system, the selector lever must be
moved and held in position N for
five seconds. P illuminates in the
transmission display to indicate that
the sensor matching process can be
started.
Tyre pressure monitoring system
3 200.
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. A warning
message is displayed in the Driver
Information Centre (DIC). Vehicle
messages 3 100.
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.
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 ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.
■ The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.

Driving and operating143
KickdownIf the accelerator pedal is presseddown completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
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
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 100.
Continued driving is restricted or not possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.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 89.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs
a self-test which may be audible.
Control indicator u 3 89.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
