174Driving and operatingassistant. The detected speed limit
can be used as new value for the
speed limiter.
Using a camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs. The system also takes
account of information on speed limits from the navigation map data.
The function can be activated or deactivated in the personalisation
menu 3 118.
If the speed limiter is active, the
recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates.

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 Road
Signs and Signals.
Adaptive cruise control
The adaptive cruise control is an
enhancement to the conventional
cruise control with the additional
feature of maintaining a certain
following distance to the vehicle
ahead. It uses a camera at the top of
178Driving and operatingstart 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 to maintain 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.
The adaptive cruise control is
deactivated automatically when:
● The brake pedal is depressed.
● The vehicle accelerates above 180 km/h or slows down below
30 km/h.
Driving and operating179● The electric parking brake isapplied.
● The Traction Control system or Electronic Stability Control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the Electronic Stability Control.
Switching off the system
Press C, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.
Pressing ß to activate the speed
limiter deactivates adaptive cruise
control.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the system when the spare wheel is in use.
System limits9 Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
● Do not use the adaptive cruise control when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
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
Driving and operating183Forward collision alert 3 181
Front pedestrian protection 3 185
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.
Functionality
Active emergency braking is
equipped with a front camera and
operates in forward gear in the range
between walking speed and 85 km/h.
The system detects stationary
vehicles only if the speed does not
exceed 80 km/h.
A precondition is that active
emergency braking is not deactivated
in the vehicle personalisation menu
3 118.
If deactivated, m illuminates in the
instrument cluster and a warning
message is displayed in the Driver
Information Centre
If the system has been deactivated
manually, it is reactivated
automatically the next time the
ignition is switched on.
The system includes: ● emergency automatic braking
● forward collision alert
● front pedestrian protectionEmergency 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.
Front automatic braking can only
occur if a vehicle or a pedestrian
ahead is detected.
Forward collision alert 3 181
Front pedestrian protection 3 185
Below a speed of 30 km/h,
emergency automatic braking may
slow down the vehicle to a complete
stop. If the speed exceeds 30 km/h, emergency automatic braking
reduces the speed. However, the
driver must apply the brake.
Vehicle care221Warning label
Meaning of symbols:● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Power saving mode This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Changing into power saving mode
When power saving mode is
activated, a message appears in the
Driver Information Centre indicating
Power saving mode .
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.Deactivating power saving mode
Power saving mode is deactivatedautomatically when the engine is
restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes
Diesel fuel system bleeding
If the tank has been run dry, the diesel fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds. Repeat this process after no less than five seconds. If the
engine fails to start, seek the
assistance of a workshop.
