Driving and operating151To reduce the operating forces ofthe parking brake, depress the
brake pedal at the same time.
Control indicator R 3 86.
Electric parking brake
Applying when vehicle is stationary
9 Warning
Pull switch m for approx.
one second, the electric parking
brake operates automatically with
adequate force. For maximum
force, e.g. parking with trailer or on
inclines, pull switch m twice.
The electric parking brake is
applied when control indicator m
illuminates 3 86.
The electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often without engine
running, as this will discharge the
vehicle battery.
Before leaving the vehicle, check the electric parking brake status. Control
indicator m 3 86.
Releasing
Switch on ignition. Keep brake pedal
depressed and then push switch m.
Drive away function
Vehicles with manual transmission:
Depressing the clutch pedal and then
slightly releasing the clutch pedal and
slightly depressing the accelerator
pedal releases the electric parking
brake automatically. This is not
possible when the switch m is pulled
at the same time.
Vehicles with automatic transmission: Engaging D and then depressing the
accelerator pedal releases the
electric parking brake automatically. This is not possible when the switch
m is pulled at the same time.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electric parking brake
is indicated by control indicator j and
by a code number or a vehicle
message which is displayed in the
Driver Information Centre. Vehicle
messages 3 97.

154Driving and operatingFor a more sporty behaviour ESC and
TC can be deactivated separately:
● Press b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates.
● Press and hold b for min. five
seconds: TC and ESC are
deactivated, k and n illuminate.
Additionally, the selected mode is
displayed as status message in the
Driver Information Centre.
If the vehicle comes into threshold
with deactivated ESP, the system will reactivate ESP for the time duration
of the threshold, when the brake
pedal is depressed once.
ESC is reactivated by pressing b
again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.Deactivation, VXR version
For very high-performance driving
ESC and TC can be deactivated
separately. The following modes are
selectable:
● Press b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates.
● Press b twice briefly within
2 seconds: TC is inactive, ESC is
operable without engine power
reduction, k and n illuminate.
● Hold b pressed for min.
5 seconds: TC and ESC are
completely inactive, k and n
illuminate.
Additionally the selected mode is
displayed as status message in the
Driver Information Centre.
On VXR version TC and ESC remain
deactivated even if the vehicle comes into threshold with unstable
driveability.
ESC is reactivated by pressing b
again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.
Interactive driving system Flex RideFlex Ride driving system allows the
driver to select between three driving
modes:
● SPORT mode: press SPORT,
LED illuminates.
● TOUR mode: press TOUR, LED
illuminates.
● NORMAL mode: both SPORT
and TOUR are not pressed, no
LED illuminates.

Driving and operating155Deactivate SPORT mode and TOUR
mode by pressing the corresponding
button once more.
In each driving mode, Flex Ride
networks the following electronic
systems:
● Continuous Damping Control
● Accelerator Pedal Control
● Steering Control
● Electronic Stability Control (ESC)
● Antilock brake system (ABS) with
cornering brake control (CBC)
● Automatic transmissionSPORT mode
The settings of the systems are
adapted to a sportier driving style:
● Damping of shock absorbers reacts more stiffly to providebetter contact with the road
surface.
● The engine reacts more quickly to the accelerator pedal.
● Steering support is reduced.
● Shift points of automatic transmission occur later.
● With SPORT mode activated, the
illumination of main instruments changes from white to red.
TOUR mode
The settings of the systems are
adapted to a comfort driving style:
● Damping of shock absorbers reacts more softly.
● Accelerator pedal reacts with standard settings.
● Steering support is in standard mode.● Shift points of automatictransmission occur in a comfort
mode.
● Illumination of main instruments is white.
NORMAL mode
All settings of the systems are
adapted to standard values.
Drive mode control Within each manual selected driving
mode SPORT, TOUR or NORMAL,
the Drive Mode Control (DMC)
detects and analyses continuously the real driving characteristic,
responses by the driver, and the
active dynamic state of the vehicle. If
necessary, the control unit of DMC
automatically changes the settings
within the selected driving mode or,
when recognising greater variations,
the driving mode is changed for the
length of variation.
If, for example, NORMAL mode is
selected and DMC detects a sporty
driving behaviour, DMC changes
several settings of the Normal mode

Driving and operating187Caution
Use of fuel that does not comply toEN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel for liquid gas operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under its French name GPL (Gaz de Pétrole
Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between 105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing LPG switches between
petrol and liquid gas operation as
soon as the required parameters (coolant temperature, gas
temperature and minimum engine
speed) have been reached. The
requirements are usually fulfilled after
around 60 seconds (depending on
exterior temperature) and the first firm press on the accelerator. The LED
status shows the current operating
mode.1 off:petrol operation1 flashes:checking conditions

Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating the wheels or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced.
The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure sensor.
The malfunction light w and the
warning message or code should
extinguish at the next ignition cycle.
The sensors are matched to the
wheel positions using a relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until the sensor is matched.
Consult a workshop for service. There
are two minutes to match the first
wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate the receiver is in
relearn mode.
7. Start with the left side front wheel.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.
