Driving and operating161Regeneration on demand
Regeneration on demand allows
increased deceleration by pressing
and holding the steering wheel
paddle. It works in D (Drive) and L
(Low). The accelerator pedal must be mostly released for it to work.
If regenerative braking is active, the regenerative active icon with arrowsis shown as green. Regenerative
braking 3 77.
Cruise control will switch off and the
brake lights may come on when this
feature is activated.
If the vehicle is in D (Drive) and is
brought to a complete stop while the regenerative braking paddle is held,
the vehicle will not creep forward
when the paddle is released. The
accelerator pedal must be pressed to
move the vehicle forward. Refer to
"One-pedal driving” in Electric drive
unit 3 155.
If the vehicle is on a steep gradient,
the brake pedal will be required to
hold the vehicle.
The brake controller applies the
hydraulic brakes using a pump. You
may hear the pump during some
braking manoeuvres, such as rapid
brake application or during
regenerative braking as the vehicle
comes to a stop. This is normal
operation.
Hill Top ReserveHill Top Reserve enables you to
maximise regenerative braking
efficiency when driving from a higher
elevation immediately after charging.
When switched on, this feature will
stop the charging process before thehigh voltage battery is full, allowing space for energy from regenerative
braking.
This feature also integrates with the Location-based charging feature,
allowing you to configure the system
so it is enabled when you are at home ( On – home only ) or away (On – away
only ). See "Location based charging"
in Programmable charging 3 197.
162Driving and operatingRide 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.

Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer/oversteer),
electric drive unit output is reduced and the wheels are braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.ESC is operational as soon as the

follows:
1. Stop the vehicle.
2. Switch off the vehicle and wait for
15 seconds.
3. Switch on the vehicle. If b still illuminates and remains
illuminated, seek the assistance
of a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds of approx. 25 km/h
or more.
Deviations from the stored speeds may occur when driving uphill or
downhill.
With the Traction Control system or
Electronic Stability Control, the
system may limit wheel spin while
using cruise control. If this happens,
the cruise control will automatically
disengage.
Traction Control system 3 162,
Electronic Stability Control 3 163.
If a collision alert occurs when cruise
control is activated, cruise control is
disengaged. Forward collision alert
3 167.
Do not use the cruise control if it is not
advisable to maintain a constant
speed.
Driving and operating169approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic,
weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be ready to take action and apply the
brakes.
System limitations
Forward collision alert is designed to warn about vehicles only, but may
react also to other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt,
windscreen damage or affected
by foreign items, e.g. stickers
Following distance
indication
The following distance indication
displays the distance in seconds to a
preceding moving vehicle. The front
camera in the windscreen is used to
detect the distance of a vehicle
directly ahead in the vehicle's path. It
is active at speeds above 8 km/h.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre.
Select Information menu via steering
wheel buttons and press G to select
following distance indication 3 83.
The minimum indicated distance is
0.5 seconds.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- sec.
Active emergency braking
Active emergency braking can help toreduce the damage and injury from
crashes with vehicles, pedestrians and obstacles directly ahead, when a
collision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert 3 167 and front pedestrian
protection 3 172.
The feature uses various inputs (e.g.
camera sensor, brake pressure,
vehicle speed) to calculate the
probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
Driving and operating179FunctionalityParking slot searching mode,
indication in the Info display
Select parallel or perpendicular
parking slot by touching the
respective icon on the display.
Select parking side by touching the
respective icon on the display.
When a slot is detected, a visual
feedback on the Info display and an
acoustic signal is given.
If the driver does not stop the vehicle after a parking slot is proposed, the
system starts to search for another
suitable parking slot.
Park guiding mode
The parking slot suggestion of the
system is accepted when the vehicle is stopped by the driver within
ten metres for parallel parking slots or six metres for perpendicular parking
slots after the Stop message is given.
The system calculates the optimal
path into the parking slot.
A brief vibration in the steering wheel
after engaging reverse gear indicates that the steering is controlled by the
system. Then the vehicle is steered
into the slot automatically by giving
the driver detailed instructions for
180Driving and operatingbraking, accelerating and gear
shifting. The driver must keep hands
away from the steering wheel.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound indicates that the
distance to an obstacle is less than
approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.Display indication
The instructions on the display show:
● General hints and warning messages.
● A hint when driving faster than 30 km/h during parking slot
searching mode.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The demand to shift into reverse or first gear.● The demand to stop or to driveslowly.
● For some of the instructions a progress bar is shown in the
Driver Information Centre.
● The successful completion of the
parking manoeuvre indicated by
a pop-up symbol and a chime.
● The cancelling of a parking manoeuvre.
Display priorities
Advanced parking assist indication in
the Info display can be inhibited by
vehicle messages with a higher
priority. After approving the message, advanced parking assist instructions
appear again and the parking
manoeuvre can be continued.
Deactivation
The system is deactivated by:
● a short press of (
