Post-crash label
The post-crash label is located in the
driver's door frame.
After an accident, park the vehicle
with a sufficient distance of
approx. 7.5 m to other objects.
Park on a non-flammable surface.
Call the hotline number given on the
label to get further instructions on how to handle the vehicle.
154Driving and operatingThe selector lever always starts from
a centre position. The selected gear
is indicated by a yellow LED on the
selector lever. After releasing the
selector lever, it will return to the centre position.
P : This position locks the front
wheels. It is the recommended
position when starting the propulsion system because the vehicle cannot
move easily.9 Warning
It is dangerous to get out of the
vehicle if the selector lever is not fully in P with the parking brake
firmly applied. The vehicle can roll.
Do not leave the vehicle when the propulsion system is running, the
vehicle may move suddenly. You
or others can be injured. To be
sure the vehicle will not move,
even if you are on even ground,
always apply the parking brake
and move the selector lever to P.
The release button is designed to
prevent inadvertent shifting out of P
unless the vehicle has been started,
the brake pedal is depressed, and the release button is pressed.
When the vehicle is stopped, press
POWER m to switch off the vehicle.
The electric drive unit will shift to P
automatically.
The vehicle will not shift into P if it is
moving too fast. Stop the vehicle and
shift into P.
To shift into P, press the P button on
the selector lever.
To shift out of P:
1. Depress the brake pedal and press the release button.
2. Shift into the desired gear.
R : Use this gear to reverse.
If the vehicle is shifted from either R
to D, or D to R while the speed is too
high, the vehicle will shift
automatically to N. Stop the vehicle
and shift again.
To shift into and out of R:
1. Bring the vehicle to a complete stop.
2. To shift into R, press the release
button and move the selector
lever forward, and then to the left. R is illuminated in red.
To shift out of R, shift into the
desired gear.Caution
Shifting into R while the vehicle is
moving forward could damage the electric drive unit. Only shift intoR after the vehicle has been
stopped.
Driving and operating157Car wash mode (vehicle on)To place the vehicle in N with the
vehicle running:
1. Open the door while pressing the brake, then shift to N.
2. The indicator should now show N.
If it does not, select N again.
3. Shift into P upon returning to the
vehicle.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 the journey.
When the vehicle is switched off, 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 79.
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 79.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS
are no longer available. During
158Driving and operatinghard braking, the vehicle can nolonger be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Electric parking brake
The electric parking brake can always
be activated, even if the vehicle is
switched off.
Do not operate electric parking brake
system too often when the vehicle is
switched off as this will discharge the 12 V vehicle battery.
In case of insufficient electric power,
the electric parking brake cannot be
applied or released.
Applying when vehicle is stationary9 Warning
Pull switch m for a minimum of
one second until control indicator
m illuminates constantly and

complete stop.
2. Pull switch m for approx. one
second.
The control indicator m will flash and
then stay on once the electric parking brake is fully applied. Before leaving
the vehicle, check the control
indicator m to ensure the parking
brake is applied.
If the control indicator m flashes
continuously, then the electric parking
brake is only partially applied or there
is a problem with the electric parking
brake. A message is displayed in the
Driver Information Centre. Release
the electric parking brake and try to
apply it again. If the control indicator
m does not illuminate or keeps
flashing, seek the assistance of a
workshop.
Do not drive the vehicle if the control
indicator m is flashing 3 79.
If the electric parking brake is applied while the vehicle is moving, a chimewill sound and a message will be
displayed in the Driver Information
Centre. The vehicle will decelerate as
long as the switch is pulled.
Releasing the switch m during the
deceleration process will release the
parking brake. If the switch m is
Driving and operating161Ride control systems
Traction Control system The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC).
TC 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, electric drive unit 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
control indicator b extinguishes.
When TC operates b flashes.
