244Driving and operatingABS starts to regulate brake pressureas soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.

Fault
If control indicators u and j
illuminate with a message in the
Driver Information Centre, there is a fault in the ABS. The brake system
remains operational but without ABS
regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, j , R and
C illuminate, the ABS and ESC are
deactivated and a message is shown
in the Driver Information Centre.
Have the cause of the fault remedied
by a workshop.

Active emergency braking Active emergency braking can help toreduce the damage and injury from
crashes with vehicles directly ahead,
when a collision can no longer be
avoided either by manual braking or
by steering. The feature uses various
inputs (e.g. camera sensor, radar
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
supplemental use only to reduce
the vehicle speed before a
collision.
The system only detects vehicles
driving in the same direction of
traffic.
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.
Operation conditions
The system is operational at a vehicle
speed between 10 mph and 62 mph.
Activation
The system is automatically active
when the ignition is switched on.
Functionality
When driving in the speed range
mentioned above and a risk of
collision with the vehicle ahead is
imminent, l will flash and a warning
chime sounds.
The indicator light l and the chimes
stop when the system detects that a
collision is not imminent anymore.

254Driving and operatingpedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready 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.
Additionally, warning lights l and
j illuminate at the same time.
When the system detects that its
function is not available, warning light
l or j illuminates and stays on.
Additionally, a message in the Driver
Information Centre appears. The system may be temporarily disrupted
(for example: radar or camera
obscured by dirt, mud, snow etc.). In
this case, park the vehicle and switch off the engine. Clean the windscreen
area around the camera and the
detection zone of the radar in the front bumper. When the warning lights and
messages still appear after starting
the vehicle again, seek the
assistance of a workshop.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.
The parking assist measures the
distance between the vehicle and
obstacles behind and, if available, in
front of the vehicle. It informs and
warns the driver by giving acoustic
signals.
The system consists of four ultrasonic parking sensors in the rear bumper
and, if available, four ultrasonic
parking sensors in the front bumper.

Lane departure warning The lane departure warning system
uses a front camera to observe the
lane markings between which the
vehicle is driving. The system detects
lane changes and warns the driver in
the event of an unintended lane
change via visual and acoustic
signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn lights
