Driving and operating143
Starting off
Depress the foot brake and move the selector lever to A, + or -. The
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
brake is released.
To start off without depressing the
foot brake, accelerate immediately
after engaging a gear.
If neither the accelerator nor the
brake pedal are depressed, no gear
is engaged and A or R flashes for a
brief time in the display.
Stopping the vehicle
In A, 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 fairlyhigh 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 or snow. Move the selector
lever between R and A in a repeat
pattern. 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.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.
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.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increases engine speed to quickly bring the
catalytic converter to the required
temperature.

144Driving and operating
■ The adaptive programme tailorsgearshifting to the driving
conditions, e.g. greater load or
gradients.
■ When Sport mode is engaged, shift
times are reduced and the
transmission shifts at higher engine speeds (unless cruise control is
on). Sport mode 3 148.
Winter programme T
Activate the Winter programme if you
have problems starting off on a
slippery road surface.
Activation
Press the T button. The transmission
switches to automatic mode. The
vehicle starts off in 2nd gear. Sport
mode is deactivated.
Deactivation
The Winter programme is switched off by:
■ pressing the T button again
■ turning off the ignition,
■ switching to manual mode (when switched back to automatic mode,
the Winter programme is again
active)
■ when clutch temperature is too highKickdown
If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear depending on engine speed.
During kickdown no manual gear
shifting is possible.
Fault
To prevent damage to the manual
transmission automated, the clutch is
engaged automatically at high clutch
temperatures.

Driving and operating145
A illuminates in the event of a fault.
Continued driving is possible. Manual
mode cannot be used for shifting.
If F appears in the transmission
display, continued driving is not
possible.
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 battery is discharged, start the
vehicle using jump leads 3 200.
If the cause of the fault is not a
discharged battery, seek the
assistance of a workshop.
If the vehicle must be moved out of the flow of traffic, disengage the
clutch as follows (for vehicles with 5-
speed manual transmission
automated only):
1. Apply parking brake and switch off
ignition.
2. Open the bonnet 3 161.
3. Clean the transmission around the cap so that no dirt can get intothe opening when the cap is
removed.
4. Rotate cap to slacken and remove
by lifting upwards.
5. Using a flat-head screwdriver, turn the adjusting screw under the
cap clockwise until clear
resistance can be felt. The clutch
has now been disengaged.
6. Refit cleaned cap. The cap must be in full contact with the housing.
On vehicles with 6-speed manual
transmission automated, the clutch cannot be released; if the vehicle
must be moved, raise the vehicle at
the front to tow.Caution
Do not turn beyond the resistance since this could damage the
transmission.

146Driving and operatingCaution
Towing the vehicle and starting
the engine is not permitted when
the clutch has been disengaged in this way, although the vehicle can
be moved a short distance.
Seek the immediate assistance of 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 you depress the
brake pedal firmly. Considerably
more force is needed 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.
Control indicator R 3 98.
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 98.
Adaptive brake lamp During full braking, all three brake
lamps flash for the duration of ABS
control.

150Driving and operating
With automatic transmission or
manual transmission automated, only
activate cruise control in automatic
mode.
Control indicator m 3 102.
Activation
Briefly press the m button: the current
speed is stored and maintained.
Vehicle speed can be increased by
depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed is resumed.
The speed is saved until the ignition
is switched off.
To resume the saved speed, briefly
press the g button at a speed above
30 km/h.
Increase speed
With cruise control active, hold down
button m or briefly press it repeatedly:
speed is increased continuously or in small increments.
When button m is released the
current speed is stored and
maintained.Reduce speed
With cruise control active, hold down button g or briefly press it repeatedly:
speed is reduced continuously or in
small increments.
When button g is released the current
speed is stored and maintained.
Deactivation
Briefly press the § button: cruise
control is deactivated.
Automatic deactivation: ■ Vehicle speed below approx. 30 km/h
■ The brake pedal is depressed
■ The clutch pedal is depressed
■ Selector lever in N.Object detection

Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles. It
is the driver, however, who bears full
responsibility for parking.
The system consists of four ultrasonic parking sensors in each of the front
and rear bumpers.
Control indicator r 3 98.

164Vehicle careBrake fluid9Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and the MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use high-performance brake
fluid approved for the vehicle. Brake
and clutch fluid 3 164.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.

aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 213.
Topping up engine oil
Engine oils of different manufacturers and brands can be mixed as long as
they comply with the required engine oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 213.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade
depending on the minimum ambient
temperature 3 213.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only silicate-free long life coolant
(LLC) antifreeze.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of additional coolant additives that
intend to give additional corrosion
protection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake and clutch fluid Only use high-performance brake
fluid approved for the vehicle, consult a workshop.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified
interval.
