symbol m and a message are
indicated in the Driver Information
Centre. The system is still not active.
Activation of the functionality
Setting speed by the driver
Accelerate to the desired speed and
move thumb wheel briefly to SET/-.
The current speed is stored and
maintained. Accelerator pedal can be
released.
The preset speed can then be
changed by moving thumb wheel to RES/+ to increase or to SET/- to
decrease the speed. Move thumb
wheel repeatedly to change speed in
small steps, move and hold to change speed in large steps.
152Driving and operating
Speed value is indicated in the Driver
Information Centre.
Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be used as new value for the
cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the cruise control is active, the
recognised speed limit will be
displayed in the Driver Information
Centre and "MEM" illuminates.
Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed is the new value for the
cruise control.
This function can be deactivated or
activated in the personalisation menu 3 101.
Exceeding the set speed
Vehicle speed can be increased by
depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed
is resumed.
Deactivation of the functionality
Press Ñ: cruise control is in pause
mode and a message is displayed.
The vehicle is driven without cruise
control.Cruise control is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Cruise control is deactivated
automatically when:
● The brake pedal is depressed.
● The clutch pedal is depressed.
● Vehicle speed is below 40 km/h.
● The Traction Control system or Electronic Stability Control is
operating.
● The selector lever is in N, first or
second gear.
Resume stored speed Move thumb wheel to RES/+ at a
speed above 40 km/h. The stored speed will be obtained.
Switching off the system
Press m: the cruise control mode is
deselected and the cruise control
indication extinguishes in the Driver
Information Centre.
Pressing ß to activate the speed
limiter deactivates cruise control.
154Driving and operatingAccelerate to the desired speed and
move thumb wheel briefly to SET/-.
The current speed is stored as
maximum speed.
The preset maximum speed can be changed by moving thumb wheel toRES/+ to increase or to SET/- to
decrease the desired maximum
speed. Move thumb wheel repeatedly
to change speed in small steps, move and hold to change speed in large
steps.

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 3 155 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.
Operation conditions
Active emergency braking is
equipped with a front camera and
operates in forward gear above
walking speed up to 85 km/h. The
system detects stationary vehicles
only if the speed does not exceed
80 km/h.
Activation
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 101.
Functionality The system includes: ● emergency automatic braking
● forward looking brake assist ● forward collision alert
● front pedestrian protection
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 3 155 or a
pedestrian 3 159 ahead is detected.
164Driving and operatingThe driver must control acceleration,
braking and gear shifting, while
steering is done automatically. The driver can take control at any time by
gripping the steering wheel.
It may be necessary to move forwards and backwards more than once.
Instructions are given in the Info
Display 3 97.
Advanced parking assist can only be activated when driving forwards.
Advanced parking assist is always
combined with front-rear parking assist.
The system has six ultrasonic parking
sensors each in both the rear and
front bumper.
