Driving
If the electromechanical brake servo is not
w
orking, the br
ak
e pedal must be pressed
harder, as the braking distance increases due
to the lack of assistance from the servo brake.
Brake blending
The brake energy recuperation can generate
a braking effect
›››
page 134. This braking ef-
fect depends on the selected driving pro-
gramme and the level of charge of the high-
voltage battery. If the braking effect caused
by the recuperation is very intense, the vehi-
cle’s brake lights with turn on. The electric en-
gine, when operating as an alternator, can
generate braking torque on the front wheels
based on the RPM and the temperature and
charge level of the high-voltage battery.
These variable parameters cause fluctuating
electric decelerations which are hydraulical-
ly compensated according to the driver’s de-
sires. This function is called “brake blending”
and it combines mechanical braking with the
engine brake effect.
WARNING
Driving at high speed on icy, slippery wet
ground can result in l
oss of vehicle control
and serious injury to the driver and passen-
gers.
●
The ESC, ABS, ASR, EDS or HBA systems
are neither in conditions to exceed the lim-
its established by the laws of physics. Al-
ways bear this in mind, especially on wet or
slippery roads. If you notice the systems
cutting in, you should reduce your speed
immediat
ely to suit the road and traffic
conditions. Do not be encouraged to take
risks by the presence of more safety sys-
tems. If you do, an accident may occur.
●
Please remember that the accident risk
always increases if you drive fast, espe-
cially in corners or on a slippery road, or if
you follow too close behind the vehicle in
front of you. The ESC, ABS, ASR, EDS or HBA
system cannot prevent accidents from oc-
curing: risk of accidents!
●
Accelerate with caution on slippery sur-
faces (for example, icy or snow-covered).
Despite the control systems, the driven
wheels could spin, affecting the stability of
the vehicle: risk of accident!
Note
●
The ABS and ASR will only operate cor
-
rectly if the four wheels have identical
tyres. Any differences in the rolling radius
of the tyres can cause the system to re-
duce engine power when this is not desired.
●
The regulating processes of the systems
can make noises due to their operation.
●
If the warning lamp or lights up,
there could be a fault

page 65.
●
Any modifications made to the vehicle
(for example, to the engine, brake system,
running gear or to the combination of
wheels and tyres) may affect the operation
of the ABS, ASR and EDS.
Parking
To park the vehicl
e
When parking your vehicle, all legal require-
ments should be observed.
Al
ways note the following points when park-
ing the vehicle:
●
Park the vehicle on a suitable surface
›››
.
●
Apply the handbrake
›

page 152.
●
Set the selector lever to the P position.
●
Connect the drive system.
●
Turn the steering wheel slightly to engage
the steering lock.
●
When leaving the vehicle, take all keys with
you.
Additionally, on steep slopes and inclines
Before switching off the engine, rotate the
steering wheel so that if the vehicle should
move, it will be held by the kerb.
●
On slopes, turn the front wheels so that
they are against the edge of the kerb.
●
Uphill, turn the wheels towards the centre of
the road.
