Driving economically The following advice is intended to
help maximise energy efficiency and
range.
In colder temperatures, while these
efficiency tips will help, the electric
vehicle's driving range may be lower
due to higher energy usage.
The weight of additional cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling the
vehicle will reduce electric vehicle
range.
Always keep the tyres properly
inflated and the vehicle properly
aligned.
Driving style
Avoid unnecessary rapid
accelerations and decelerations.
Use cruise control when appropriate.
Driving and operating169supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes
and steer to avoid collisions.
Functionality
If equipped only with front camera the
active emergency braking operates in
a forward gear above walking speed
up to 80 km/h.
A precondition is that the system is
not deactivated in the vehicle
personalisation menu 3 91.
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● front pedestrian protection system
Brake preparation system
When approaching a vehicle ahead
or a pedestrian so quickly that a
collision is likely, the brake
preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that
braking can occur more rapidly.
If equipped only with front camera the system operates up to a speed of
80 km/h.
Emergency automatic braking After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prevent a crash.
Depending on the situation, the
vehicle may automatically brake
moderately or hard. This front
automatic braking can only occur if a
vehicle ahead is detected, indicated
by the vehicle ahead indicator A
3 166. On vehicles with frontpedestrian protection, automatic
braking can also occur when a
pedestrian ahead is detected,
indicated by the pedestrian ahead
indicator 7.
The system operates up to a speed of
80 km/h.
Below a speed of 40 km/h the system can apply full braking.
Emergency automatic braking may slow the vehicle to a complete stop to
try to avoid a potential crash. If this
happens, emergency automatic
braking may engage the electric
parking brake to hold the vehicle at a
stop. To release, push the electric
parking brake switch or firmly depress the accelerator pedal.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
170Driving and operatingnot brake outside of its operatingspeed range and only responds to
detected vehicles.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore,
depressing the brake pedal less
strongly results in immediate hard
braking. This function helps the driver
brake quicker and harder before an
imminent collision.
The system operates up to a speed of 80 km/h.
9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
Intelligent brake assist
Intelligent brake assist may activate
when the brake pedal is applied
quickly by providing a boost to
braking based on the speed of
approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal movement during this time are normal and the brake pedal should continue
to be applied as required. Intelligent
brake assist will automatically
disengage only when the brake pedal is released.
9 Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Front pedestrian protection
Front pedestrian protection 3 171.
Deactivation Active emergency braking can be
deactivated in the personalisation
menu in the Info display 3 91.
If deactivated, a message is
displayed in the Driver Information
Centre.
The system is reactivated the next time the vehicle is switched on.
System limitations In some cases, the active emergencybraking system may provide
automatic braking in situations that
seem to be unnecessary, for instance
182Driving and operatingIn the event of a fault in the system orif the system does not work due to
temporary conditions, the symbols in
the mirrors will be permanently
illuminated and a message is
displayed in the Driver Information Centre. Seek the assistance of a
workshop.
Lane change alert Additional to the side blind spot alert
3 181, lane change alert recognises
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
If the vehicle is equipped with lane change alert, side blind spot alert is
always included.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
yellow warning symbol F will
illuminate in the relevant exterior mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing yellow as a warning not to change lanes.
Lane change alert is active at all
speeds.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is
operating.
Driving and operating183Detection zones
The system sensors cover a zone of
approx. 3.5 m parallel on both vehicle
sides and approx. 3 m rearwards on
side blind zone alert (A) and approx.
70 m rearwards on lane change alert (B) on parallel lanes. The zones start
at each exterior mirror. The height of
the zone is approx. between 0.5 m
and 2 m off the ground.
Deactivation Activation or deactivation of the lane
change alert can be set in the vehicle personalisation menu in the Info
display.
Vehicle personalisation 3 91.
Info display 3 85.
Deactivation is indicated by a
message in the Driver Information
Centre.
Note
Each new vehicle requires a
calibration. For optimal
performance, drive as soon as
possible on a straight highway road
with roadside objects, e.g. guardrails
and barriers for some distance.
System limitations
Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to
a wet area can cause the system to
light up, as water splash can be
interpreted as an object. Otherwise F may illuminate due to guardrails,
signs, trees, shrubs or other immobile
objects. This is normal operation and
the system does not need a service.The system may not operate properly
when:
● ice, snow, mud, or anything else covers the sensors
● driving in heavy rainstorms
● the vehicle had an accident
● there are extreme temperature changes
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Panoramic view system The panoramic view system vision
displays an image of the area
surrounding the vehicle, along with
the front or rear camera views in the
centre console.
186Driving and operating
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture, which
show obstacles detected by the rear
sensors of the advanced parking
assist.
Additionally, 9 appears on the top
line of the Info display with the
warning to check the vehicle
surroundings.
Display settings
Brightness and contrast can be set by
touching the touch screen display
when rear view camera is active.
Deactivation The camera is switched off when a
certain forward speed is exceeded or

Fault
Fault messages are displayed with a
9 on the Driver Information Centre.
The rear view camera may not
operate properly when:
● The surrounding is dark.
● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The vehicle had a rear end accident.
● There are extreme temperature changes.
190Driving and operatingAlternatively, 9 can be pressed for
three seconds to clear the content of
the page.
In some cases, traffic sign assistant is
cleared up automatically by the
system.
Clearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” or a sign from
navigation map data is displayed in
the Driver Information Centre.
Reasons for signs being cleared: ● A predefined distance was driven
or time has elapsed (differs for
each sign type)
● Vehicle drives through a turn
● If speed drops below 52 km/h (city entry detection)
Fault
Traffic sign assistant may not operate
correctly if:
● The area of the windscreen, where the front camera is
located, is not clean or affected
by foreign items, e.g. stickers.
● Traffic signs are completely or partially covered or difficult to
discern.
● There are adverse environmental
conditions, e.g. heavy rain, snow,
direct sunlight or shadows.
● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on Road
Signs and Signals (Wiener
Übereinkommen über
Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings between
which the vehicle is driving. If the
vehicle approaches a lane marking, the steering wheel is gently turned to
position the vehicle back into the lane.
Override the system by turning the
steering wheel.
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.
