personalisation menu 3 91.
The forward collision alert will be activated again with the last selected
alert sensitivity when the vehicle is
switched on next time.
General information
9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching 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 82.
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.
172Driving and operating9Warning
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 3 172.
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
in parking garages, due to traffic signs in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
a service. Firmly apply the accelerator
pedal if the situation and
surroundings permit to override the
automatic braking.
In the following cases, active
emergency braking performance is
limited:
● When driving on winding or hilly roads.
● When not all vehicles are detected, especially vehicles witha trailer, tractors, muddy
vehicles, etc.
● When detecting a vehicle when weather limits visibility, such as in
fog, rain, or snow.
● During nighttime driving.
● When weather limits visibility, such as fog, rain, or snow.
● When the sensor in the windscreen is blocked by snow,
ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers.To avoid malfunction keep the areas
of the camera sensor in the
windscreen always clear of dirt, dust,
ice and snow.
Complete attention is always required while driving, and you should beready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 89.
Front pedestrian protection
The front pedestrian protection
system may help avoid or reduce the
harm caused by front-end crashes
with nearby pedestrians when driving in a forward gear.
Driving and operating173The system uses the front camera inthe windscreen to detect a pedestrian
directly ahead in your path.
The front pedestrian protection
system can detect and alert about
pedestrians when in a forward gear at
speeds between 8 km/h and
80 km/h.
Additionally, the front pedestrian
protection system can provide a
boost to braking or automatically
brake the vehicle.
During daytime driving, the system
detects pedestrians up to a distance
of approximately 40 m. During
nighttime driving, system
performance might be limited.
The front pedestrian protection can be set to Off, Alert or Alert and
Brake in the vehicle personalisation
3 91.9 Danger
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.
174Driving and operatingAutomatic 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 3 159.
This system includes intelligent brake
assist, and the emergency automatic
braking system may also respond to
pedestrians.
Active emergency braking 3 170.
Automatic braking can be disabled
through vehicle personalisation 3 91.General information9 Warning
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
9 Warning
Front pedestrian braking may alert
or automatically brake the vehicle
suddenly in situations where it is
unexpected and undesired. It
could falsely alert or brake for
objects similar in shape or size to
pedestrians, including shadows.
This is normal operation and the
vehicle does not need a service.
To override Automatic braking,
firmly depress the accelerator
pedal, if it is safe to do so.
System limitations
In the following cases, front
pedestrian protection may not detect
a pedestrian ahead or sensor
performance is limited:
● When vehicle speed is out of range from 8 km/h to 80 km/h .
● When the distance to an pedestrian ahead is more than
40 m.
● When weather limits visibility, such as fog, rain, or snow.
● During nighttime driving.
● When the sensor in the windscreen is blocked by snow,
ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers.
Parking assist
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
Driving and operating191Alternatively, 9 can be pressed for
3 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.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.
When crossing a lane marking
significantly, lane keep assist starts a
visual and acoustic warning.
Driving and operating193timing of alert and the occurrence of
alert. Move the steering wheel to stop
the alert.
Deactivation The system is deactivated by
pressing a. The LED in the button
extinguishes.
The system is reactivated the next time the vehicle is switched on.
Fault
The system performance may be affected by:
● windscreen not clean or affected by foreign items, e.g. stickers
● close vehicles ahead
● banked roads
● winding or hilly roads
● road edges
● roads with poor lane markings
● sudden lighting changes
● adverse environmental conditions e.g. heavy rain or
snow
● vehicle modifications, e.g. tyresSwitch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
The system does not detect
pedestrians, cyclists or animals on
the road. Steer the vehicle
manually to avoid injuries and
deaths.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert, even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences (road condition and
surface, weather etc). The driver
has full responsibility to control the vehicle and is always required tokeep the hands on the steeringwheel while driving.
Using the system while driving on
slippery roads could cause loss of control of the vehicle and a crash.
Switch off the system.
204Driving and operatingProgrammable charging disabled
When the programmable charging
system is disabled, the Unable to
charge screen will be displayed.
Programmed charging override
To temporarily override a delayed charge event, unplug the charge cord from the charge port and then plug it
back in within 5 seconds. A single
horn chirp will sound and charging will begin immediately.
To cancel a temporary override,
unplug the charge cord, wait for
10 seconds, and then plug the charge cord back in. A double horn chirp will

Programmable charging 3 197.
Charging status
The vehicle has a charging status
indicator at the centre of the
instrument panel near the
windscreen. When the vehicle is
plugged in and the vehicle power is
off, the charging status indicator
indicates the following:
● Short flashing green – One horn chirp: Vehicle is plugged in. High
voltage battery is not fully
charged. High voltage battery is
charging. Flash rate increases
from one to four flashes as the
high voltage battery charges.
● Short flashing green – Two audible beeps: Vehicle is
charging but will delay by
programmable charging at least
once before the charge is
complete. Flash rate increases
from one to four flashes as the high voltage battery charges.
● Short flashing green – Four audible beeps: Insufficient time to
fully charge by departure time due to the selected rate
preference. To increase the high
voltage battery state of charge at
the departure time perform a
delayed charging override.
Programmable charging 3 197.
● Long flashing green – Two horn chirps: Charging is delayed by
programmable charging.
Charging will begin later.
216Vehicle careWasher fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
When adding windscreen washer
fluid to the vehicle, be sure to read the
manufacturer's instructions before
use.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
● When using concentrated washer fluid, follow the
manufacturer's instructions for
adding water.
● Do not mix water with ready-to- use washer fluid. Water can
cause the solution to freeze and
damage the washer fluid tank
and other parts of the washer
system.
● Fill the washer fluid tank only three quarters full when it is verycold. This allows for fluid
expansion if freezing occurs,
which could damage the tank if it
is completely full.
● Do not use engine coolant (antifreeze) in the windscreen
washer. It can damage the
windscreen washer system and
paint.
Washer fluid 3 248.
Brakes In the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
