G
WARNING
Do not turn off the drive system before the
vehicle has come to a complete stop. With
the drive system not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to
keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle.
X Depress the brake pedal.
X Move the gear selector lever to park
position P.
The transmission position indicator
should be on P !
Always engage the parking brake in
addition to shifting to park position P.

WARNING
The operating condition of the high-
voltage battery (e.g. not yet at normal
operating temperature or fully charged)
influences the braking effect of the
electric motor.
In overrun or braking mode, the motor's
braking effect may therefore be reduced or
may not be present at all.
As a result of the reduced engine braking
effect, you may cause an accident and
injure yourself or others. Transmission
77>> Controls.
* optional Z
Compensate for the reduced engine braking
effect by pressing the brake pedal
accordingly, as required.
Using the steering wheel paddle shifters,
you can increase or decrease the
recuperation in overrun phases.
Recuperation means that energy is
recovered while driving - the electric
motor functions as a generator. The kinetic
energy of the vehicle is converted into
electric power and stored in the high-
voltage battery. The more the recuperation
increases, the more the vehicle will be
decelerated.
In overrun phases, there are three levels of
recuperation:
R no recuperation (level 0, coasting)
R mid-level recuperation (level 1)
R high-level recuperation (level 2)
The amount of recuperation in overrun
mode is displayed in the power gauge
(Y page 79).
When you switch on the ignition, level 1 is
automatically preset. X
Decrease recuperation: Pull left
steering wheel paddle shifter 0002.
X Increase recuperation: Pull right
steering wheel paddle shifter 0003.Use the different levels 0 to 2 for
conditions as described below: Level 0 Driving without frequent
breaking. No sharp bends on
the road ahead.
Maximum kinetic energy
remains for the vehicle.
Level 1 Normal driving, standard
setting.
Level 2 Sporty driving.
The break pedal has to be
depressed less often, as the
deceleration due to
recuperation is higher than
in level 1.
The energy efficiency is
substantially higher than if
the vehicle is decelerated by
depressing the brake pedal.
At levels
1and 2the vehicle can be
steplessly decelerated by depressing the
brake pedal.
i Under certain circumstances, in
overrun phases recuperation does not
work as described above. This may be e. g
the case if the high-voltage battery is
already fully charged or has not reached
operating temperature. Driving tips
Driving on uphill grades G
WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the parking brake in
addition to shifting to park position P.78
Transmission>> Controls.
!
When the hill‑start assist system stops
braking the vehicle, it can roll
backwards.
If you open the driver’s door, the
hill‑start assist system is deactivated
and a warning signal sounds.
Your vehicle has a hill‑start assist system.
On uphill grades the hill‑start assist
system maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal.
Therefore, you can start off smoothly
without the vehicle moving immediately
after releasing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal to drive off.
On uphill grades with higher inclination,
the hill-start assist system will release
the pressure in the brake system after
approximately two seconds. A warning
signal sounds and the transmission
position indicator shows a flashing N in
order to warn you of the vehicle rolling
backwards.
X Press the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal to drive off.

WARNING
When the indicator for the maximum
available power is not at its maximal
range, the power output is reduced
noticeably. Adapt your speed and driving
accordingly. Otherwise, you could cause an
accident. Exercise particular care when
passing or accelerating. The indicator for the maximum available
power of the drive system contains three
segments

indicates power that is currently
available.
R Three segments: maximum power is
available.
R Two segments: Less than 66 % amount of

R One segment: Less than 33 % amount of
power is available.
Under normal operating conditions the
indicator for the maximum power is at the
maximum range 0002.
The available amount of power can vary
from the the maximum range due to:
R very high or low outside temperatures
R very high power demand over along time

R very low charge level of the high-voltage
