Driving and operating149Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 92.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as 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.
When braking in an emergency, the
hazard warning flashers are switched
on automatically depending on the
force of deceleration. They are
switched off automatically the first
time you accelerate.
After starting off, the system performs
a self-test which may be audible.
Control indicator u 3 92.
Fault9 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.
Have the cause of the fault remedied
by a workshop.
Parking brake
9 Warning
Before leaving the vehicle, check
parking brake status. Control
indicator R must illuminate
constantly.
150Driving and operatingManual parking brake9Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
Control indicator R 3 92.
Brake assist
If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further two seconds. The
brakes release automatically as soon
as the vehicle begins to accelerate.Ride control systems
Electronic Stability Control and Traction Control system
Electronic Stability Control 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),
engine output is reduced and the
wheels are braked individually.
Electronic Stability Control operates
in combination with the Traction
Control system. It prevents the driven wheels from spinning.
The Traction Control system is a
component of the Electronic Stability
Control.
Traction Control improves driving
stability when necessary, regardless
of the type of road surface or tyre grip,
by preventing the driven wheels from
spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
156Driving and operatingSpeed limiter is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Resume limit speed Press Ñ. The stored speed limit will
be obtained.
Switching off
Press ß, the speed limiter mode is
deselected and the speed limit
indication extinguishes in the Driver
Information Centre.
Pressing m to activate cruise control
deactivates speed limiter.
The preset speed remains in the
memory when the ignition is switched
off.
Fault
In the event of a speed limiter fault,
the speed is cleared resulting in
flashing of the dashes.
The speed limiter may not operate
correctly if traffic signs do not comply with the Vienna Convention on RoadSigns and Signals (Wiener
Übereinkommen über
Straßenverkehrszeichen).
Forward collision alert The forward collision alert may help to
avoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen to
detect a vehicle directly ahead, in
your path.
The system triggers different level of
alerts depending on the risk of
collision detected. The alerts are
displayed in the Driver Information
Centre.
Level 1: A visual alert is displayed.
Level 2: A visual alert is displayed and an audible alert sounds.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.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.
Driving and operating157When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, a warning
is displayed in the Driver Information
Centre.
Simultaneously a warning chime
sounds. Depress the brake pedal and
steer the vehicle, if it is required by the
situation.
Operation conditions The following condition must be
fullfilled for proper operation:
The speed must be between 5 km/h
and 140 km/h.
Activation To use forward colision alert, active
safety braking has to be activated in
the vehicle personalisation 3 103.
Selecting the alert sensitivity
The alert sensitivity has to be set to
close, normal or distant in the vehicle
personalisation menu 3 103.Deactivation
The system can only be deactivated
by deactivating the active emergency
braking in the vehicle personalisation
3 103.
System limitations Forward collision alert is designed to
warn on 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:
● Driving on winding or hilly roads.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
and obstacles directly ahead, when acollision 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 3 156 or the front pedestrian
protection alert 3 159.
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
supplemental 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.
158Driving and operatingOperation conditions
Active emergency braking is
equipped with a front camera and
operates in forward gear above
walking speed up to 85 km/h.
Activation
Active emergency braking can be
activated in the vehicle
personalisation menu 3 103.
Functionality
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● forward collision alert
● front pedestrian protection
Brake preparation system
When approaching a vehicle ahead
or a pedestrian so quickly that a
collision is likely, the brake
preparation system slightly
pressurizes 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.
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
prohibit a crash. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle 3 156 or a
pedestrian 3 159 ahead is detected .
Emergency automatic braking may slow the vehicle to a complete stop to
try to avoid a potential crash.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
not brake outside of its operating
speed range and only responds to
detected vehicles and
pedestrians.
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, pressing
the brake pedal less strongly results
in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.
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
Driving and operating159lane 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.
The system is designed to work with
all occupants wearing their seat belts.

Deactivation Active emergency braking can be
deactivated in the vehicle
personalisation menu 3 103. If
deactivated a message is displayed in the Driver Information Centre.
System limitations
In some cases, the active emergency braking system may provide an
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
service. Firmly apply the accelerator
pedal 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.
● During nighttime driving.● Weather limits visibility, such as fog, rain, or snow.
● The windscreen is damaged or affected by foreign items, 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.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 102.
Front pedestrian protection Front pedestrian protection may help
to avoid or reduce the harm caused
by front-end crashes with nearby
pedestrians when driving in a forward
gear.
