pedal, pull the ring under the selector
lever and move the selector lever
quite to the left and front.
If the gear does not engage, set the
selector lever to neutral, release the
clutch pedal and depress again. Then
repeat gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
When clutch slip is detected for a specific time, the engine power will be reduced. A warning is displayed in the
Driver Information Centre. Release
the clutch.Caution
It is not advisable to drive with the hand resting on the selector lever.

Brakes
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 m 3 95.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating151ABS 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 96.
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.

Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above 25 mph.
Additionally at least the third gear
must be engaged on manual
transmission, on automatic
transmission position D or the second
or a higher gear in position M must be
selected.
Deviations from the stored speeds may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
The status and preset speed is
displayed in the Driver Information Centre.
Do not use the cruise control if it is not advisable to maintain a constant

Electric parking brake 3 151.9 Warning
When the system is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
start moving. Be always prepared
to manually apply the brake to hold the vehicle stationary.
Do not leave the vehicle while it is
being held at a stop by adaptive
cruise control. Always move
selector lever to park position P
and switch off the ignition before
leaving the vehicle.
Setting the following distance
When adaptive cruise control detects
a slower moving vehicle in the driving path, it will adjust the vehicle speed tomaintain the following distance
selected by the driver.
The following distance can be set to
close (1 bar), normal (2 bars) or far (3 bars).
If the engine is running and the
adaptive cruise control is enabled
(grey), you can modify the following
distance setting:
Press Ö, the current setting is shown
in the Driver Information Centre.
Press Ö again to change the following
distance: The new setting is
displayed in the Driver Information
Centre.
The selected following distance is
indicated by full bars in the adaptive
cruise control page.9 Warning
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
Following distance must be
adjusted or the system switched
off when required by the prevailing
conditions.
Detecting the vehicle ahead
If the system detects a vehicle in the
driving path, the adaptive cruise
control symbol displayed in the Driver
Information Centre changes: - is
changed to w.
Deactivation of the functionality
Press Ñ, the adaptive cruise control
is in pause mode and a message is
displayed. The vehicle is driven
without adaptive cruise control.
The adaptive cruise control is
deactivated, but not disabled. The
last stored set speed remains in
memory for later usage.
Driving and operating167● Do not use the adaptive cruisecontrol when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
As the radar's field of detection is
quite narrow, it is possible that the
system may not detect:
● vehicles of reduced width, e.g. motorcycles, scooters
● vehicles not running in the middle
of the lane
● vehicles entering a corner
● vehicles suddenly pulling out
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
longer detects any vehicle ahead,
then control indicator A will
extinguish.
If the centrifugal force is too high in a bend, the system slows down the vehicle slightly. This braking level is
not designed to avoid spinning-off the
bend. The driver is responsible for
reducing the selected speed before
entering a bend and in general to
adapt the speed to the road type and
to existing speed limits.
Motorways
On motorways, adapt the set speed
to the situation and the weather.
Always consider that adaptive cruise
control has a limited visibility range, a
limited braking level and a certain
reaction time to verify if a vehicle is on
the driving path or not. Adaptive
cruise control may not be able to
brake the vehicle in time to avoid a
collision with a much slower vehicle or after a lane change. This is
particularly true while driving fast or if the visibility is reduced due to weather
conditions.
While entering or exiting a motorway,
adaptive cruise control may lose the
vehicle ahead and accelerate up to
the set speed. For this reason,
decrease the set speed before the
exit or before the entry.
Vehicle path changes
If another vehicle enters your driving
path, adaptive cruise control will first
consider the vehicle when it is
completely in your path. Be ready to

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
● driving during nighttime● weather limits visibility, such as fog, rain, or snow
● the sensor in the windscreen or the radar unit behind the front
bumper are blocked by snow, ice,
slush, mud, dirt etc.
● the windscreen is damaged or affected by foreign objects, 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 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 3 168 or the front pedestrian
protection alert 3 173.
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 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.
Operation conditions
If equipped only with front camera the
active emergency braking operates in
forward gear above walking speed up to 53 mph. With radar sensor and
front camera active emergency
braking operates in forward gear in
the range between walking speed
and 87 mph.
Driving and operating171ActivationA precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 105.
Functionality
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist
● intelligent brake assist (only with radar sensor)
● 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
pressurises the brakes. This reduces
the response time when a braking is
required.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. If active emergency
braking is applied, m flashes in the
instrument cluster. 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 3 168 . On vehicles with front
pedestrian protection, front automatic
braking can also occur when a
pedestrian ahead is detected 3 173.
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 press the electric
parking brake button or firmly press
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
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.
