are below 0 °C to maximise high
voltage battery life.
Should the exterior temperature be
lower than -32 °C, the vehicle must be
plugged in when the vehicle is
switched on.
Parking Note
Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
being plugged in.
Driving and operating153Electric vehicle
operation modes
Operation This vehicle is a purely electrically
driven vehicle. It always uses an
electric propulsion system to drive the
vehicle. Electricity is the vehicle's only source of energy.
Drive modes Sport modeSport mode provides more
responsive acceleration than normal

By switching off the vehicle, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.
Forward collision alert The forward collision alert may help toavoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera system in the
windscreen to detect a vehicle
directly ahead, in your path, within a
distance of approx. 60 m.
A vehicle ahead is indicated by the
control indicator A.
If a vehicle directly ahead is
approached too quickly, a warning
chime is sounded.
Additionally, the driver is notified by a
flashing red LED stripe which is
projected on the windscreen in the
driver's field of view.
A precondition is that forward collision alert is not deactivated in the vehicle
personalisation 3 91.
Activation
Forward collision alert operates
automatically above 8 km/h, if it is not deactivated in the vehicle
personalisation menu.
Alerting the driver
The vehicle ahead control indicator
A illuminates green in the instrument
cluster when the system has detected
a vehicle in the driving path.
The control indicator A changes to
yellow when the distance to a
preceding moving vehicle gets too
small or when approaching another
vehicle too rapidly.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.
When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, the driver
is notified by a flashing red LED stripe which is projected on the windscreen
in the driver's field of view.
172Driving and operating9Danger
Front pedestrian braking does not
provide an alert or automatically
brake the vehicle, unless it detects
a pedestrian.
The system may not detect
pedestrians, including children,
when the pedestrian is not directly ahead, not fully visible, not
standing upright, or when part of a
group.
Front pedestrian protection includes:
● detecting front pedestrian ahead● front pedestrian alert
● automatic braking
Pedestrian detected ahead
A pedestrian ahead is indicated up to
a distance of approximately 40 m by control indicator 7 in the instrument
cluster.
Front pedestrian alert
When the vehicle approaches a
detected pedestrian ahead too
rapidly, a red flashing LED alert is projected onto the windscreen in the
driver's field of view and a warning
chime is sounded. The brake system
may prepare for driver braking to
occur more rapidly which can cause a
brief, mild deceleration. Continue to
apply the brake pedal as required.
Cruise control may be disengaged
when the front pedestrian alert
occurs.
Automatic braking If a crash into a pedestrian directly
ahead is imminent and the brakes
have not been applied, the braking
strength is automatically adapted.
This can help to avoid some very low speed pedestrian crashes or reduce
pedestrian injury.
Automatic braking levels may be
reduced under certain conditions, such as higher speeds.
If this happens, automatic braking
may engage the electric parking
brake to hold the vehicle at a stop.
Release the electric parking brake. A
firm press of the accelerator pedal will
also release automatic braking and
the electric parking brake 3 158.
This system includes intelligent brake assist, and the emergency automatic
braking system may also respond to
pedestrians.
Active emergency braking 3 168.
Driving and operating191When crossing a lane marking
significantly, lane keep assist starts a
visual and acoustic warning.
Unintended lane departure is
assumed:
● without using turn signal
● using the turn signal in the opposite direction of the lane
departure
● without braking
● without acceleration
● without active steering
Note
The system is switched off during
detection of ambiguous lane
markings, e.g. in construction areas.
Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.Activation
The lane keep assist is activated by
pressing a. The LED in the button
illuminates to indicate that the system
is switched on.
When the control indicator a in the
instrument cluster illuminates green,
the system is ready to assist.
The system is operational at vehicle
speeds above 60 km/h and if lane
markings are available.
The system gently turns the steering
wheel and the control indicator a
changes to yellow, if the vehicle
approaches a detected lane marking
without using the turn signal in that
direction.
The system alerts by flashing a
together with three chimes, from the respective direction, if the lane is
departed significantly.
The system is only operable when a
lane marking is detected.
If the system only detects lane
markings on one side of the road, it
will only assist for this side.
Lane keep assist detects hands-free
driving. In this case a message in the
Driver Information Centre pops-up
and a chime sounds as long as lane
keep assist detects hands-free
driving.
