brake boost, thereby potentially reducing
the braking distance.
X Apply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The
hydraulic brake assistant is then deacti-
vated. G
WARNING
When the hydraulic brake assistant is mal-
functioning, the brake system is still func- tioning normally, but without the addi-
tional brake boost that would normally be
provided during an emergency braking
maneuver. Therefore, the braking distance
may increase. G
WARNING
The hydraulic brake assistant cannot pre-
vent the natural laws of physics from acting on the vehicle, nor can it increase braking
efficiency beyond that afforded by the con-
dition of the vehicle brakes and tires or the traction afforded. The hydraulic brake
assistant cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of a hydraulic
brake assistant equipped vehicle must
never be exploited in a reckless or dan-
gerous manner which could jeopardize the
user’s safety or the safety of others. Activating the hazard warning flasher
after an emergency braking maneuver
If you bring the vehicle to a complete stop
by strongly braking at a speed of more than
43 mph (70 km/h), the hazard warning
flasher comes on automatically as soon as the vehicle is at a standstill. The hazard
warning flasher will remain on until it is
switched off using the hazard warning
flasher switch (Y
page 68) or until the
speed of the vehicle has exceeded 6 mph
(10 km/h). Acoustic Vehicle Indication*
Vehicles with electric motors develop con-
siderably lower driving noises than vehi-
cles with combustion engines. Therefore
your vehicle in traffic might not be acous-
tically noticed by other road users in cer- tain situations.
In order to avoid this, a built-in sound
generator emits a certain noise (Acoustic
Vehicle Indication) within a speed range
between 0 to 20 mph (30 km/h). Thus, other
road users, especially pedestrians and
bicycle riders can notice your vehicle bet-
ter. Acoustic Vehicle Indication can also
be heard inside of the vehicle.
The volume of Acoustic Vehicle Indication depends on the current engine speed (rpm).The stronger you accelerate, the louder thenoise. At speed of more than 20 mph 30 km/h
the noise is switched off. From this speed
on the natural noises of the vehicle are
sufficient so that other road users can
notice the vehicle on time. Anti-theft systems
Electronic immobilizer
The electronic immobilizer prevents
unauthorized persons from starting your
vehicle.
When leaving the vehicle, always take the

WARNING
Make sure absolutely no objects are
obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats* or
carpets in the footwell, make sure the ped- als still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrictyour ability to brake or accelerate. This
could lead to accidents and/or injury. G
WARNING
A vehicle with an electric motor produces
significantly lower noise levels than a
vehicle with a combustion engine. Other
motorists or pedestrians, especially those who are visually or hearing impaired, may
be unable to hear your vehicle while it is in
motion. This is particularly true when
driving at lower speeds and during parking
maneuvers. At all times, it is the respon-
sibility of the driver to be aware of their
surroundings, especially in these low
speed situations. Otherwise other road
users could be seriously or fatally injured.
Vehicles equipped with an Acoustic Vehi-
cle Indication* emit a certain noise. Thus,
your vehicle will be better noticed by other
road users at low speeds (Y page 48).

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.
Compensate for the reduced engine braking
effect by pressing the brake pedal accord-
ingly, as required.
Using the steering wheel paddle shifters*, you can increase or decrease the recuper-
ation in overrun phases. Recuperation
takes place when you release the acceler-
ator pedal. The electric motor will then be
used as a generator and energy will be
regained while driving. The regained
energy is stored in the high-voltage bat-
tery. High recuperation decelerates your
vehicle stronger.
In overrun phases, there are three levels of recuperation:
R no recuperation (level 0, coasting)
R moderate recuperation (level 1)
R high-level recuperation (level 2)
The amount of recuperation in overrun
mode is displayed in the power gauge
(Y page 81).
The set mode for recuperation is shown in
the recuperation display (Y page 84).
When you switch on the ignition, level 1 is
automatically preset. :
Left steering wheel paddle shifter
(minus)
; Right steering wheel paddle shifter
(plus)
X Decrease recuperation: Pull left steer-
ing wheel paddle shifter :.
X Increase recuperation: Pull right steer-
ing wheel paddle shifter ;.
Use the different levels 0 to 2 for condi-
tions 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 set-
ting. Level 2 Sporty driving.
The break pedal has to be
depressed less often, as the
deceleration due to recuper-
ation is higher than in level
1.
The energy efficiency is sub-
stantially higher than if the
vehicle is decelerated by
depressing the brake pedal. At levels 1 and 2 the vehicle can be step-
lessly decelerated by depressing the brake
pedal.

run phases recuperation does not work as
described above. This may be e. g the 80

WARNING
The operating condition of the high-volt-
age battery (e.g. not yet at normal operat-
ing temperature or fully charged) influen- ces 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.

When you release the accelerator pedal
or when you depress the brake pedal, the

WARNING
Never operate radio transmitters equipped with a built-in or attached antenna (i.e.

Refer to the radio transmitter operation
instructions regarding use of an external
