186Driving and operatingResume limit speed
Turn thumb wheel to RES/+. The
stored speed limit will be obtained
and is indicated without brackets in the Driver Information Centre.
Switching off
Press L, the speed limit indication
extinguishes in the Driver Information Centre. The stored speed is deleted.
By pressing m to activate cruise
control or adaptive cruise control,
speed limiter is also deactivated and
the stored speed is deleted.
By switching off the ignition, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.
Adaptive cruise control
Adaptive cruise control is an
enhancement to conventional cruise
control with the additional feature of
maintaining a certain distance behind the vehicle ahead.Adaptive cruise control automatically
decelerates the vehicle when
approaching a slower moving vehicle. It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
vehicle speed increases or decreases to follow the vehicle in front, but willnot exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store
set speed over 30 km/h for manual
transmission. On vehicles with
automatic transmissions the system
can brake until a full stop and drive off from a stop.
Adaptive cruise control uses radar
and camera sensors to detect the
vehicles ahead. If no vehicle is
detected in the driving path, the
adaptive cruise control will behave
like a conventional cruise control.
Adaptive cruise control is mainly
advised to be used on long straight
roads like highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 115, m 3 114,
C 3 114.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the cancel
switch have priority over any
adaptive cruise control operation.

Driving and operating187Switching on
Illustrations show different versions.
Press C to switch on adaptive cruise
control. C appears in the Driver
Information Centre.
Activation by setting the speedAdaptive cruise control can be
activated at speeds above 25 km/h on
vehicles with automatic transmission
or 30 km/h on vehicles with manual
transmission. The upper speed limit is 180 km/h.
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
maintained.
The adaptive cruise control symbol
C , the following distance setting and
set speed are indicated in the Driver
Information Centre.
The accelerator pedal can be
released. Adaptive cruise control
remains activated while gearshifting.
Overriding set speed
It is always possible to drive faster
than the selected set speed by
depressing the accelerator pedal. When the accelerator pedal is
released, the vehicle returns to the
desired distance if a slower vehicle is
ahead. Otherwise it returns to the
stored speed.
Once the system is activated,
adaptive cruise control decelerates or
brakes if it detects a vehicle ahead,
which is slower or closer than the
desired following distance.9 Warning
Accelerating by the driver
deactivates automatic braking by
the system. This is indicated as a
pop-up warning in the Driver
Information Centre.

188Driving and operatingIncrease speed
With adaptive cruise control active,
hold RES/+ to increase speed
continuously. Push RES/+ repeatedly
to increase speed in small
increments.
Reduce speed With adaptive cruise control active,hold SET/- to decrease speed
continuously. Push SET/- repeatedly
to decrease speed in small
increments.
Resume stored speed
If the system is switched on but
inactive, then turn thumb wheel to
RES/+ at a speed above 25 km/h to
resume the stored speed.
Full speed range adaptive cruise
control on vehicles with automatic transmission
Full speed range adaptive cruise control will maintain a following
headway behind a detected vehicle
and slow your vehicle to a stop behind
that vehicle.In case of a brief stop of the vehicle
ahead the adaptive cruise control will drive off automatically without driveraction. If necessary, press RES/+ or
the accelerator pedal to resume
adaptive cruise control.
If the stopped vehicle ahead was
stopped for a longer time and then
begins to move forward, the green
illuminated vehicle ahead control
indicator A will flash and a warning
chime will sound as a reminder to
check traffic before proceeding.
When the vehicle ahead drives away,
press RES/+ or the accelerator pedal
to resume adaptive cruise control. If
stopped for more than five minutes or
if the driver door is opened and the
driver safety belt is unbuckled, the
electric parking brake is applied
automatically to hold the vehicle.
Control indicator m will illuminate. To
release electric parking brake, press
the accelerator pedal. Electric parking
brake 3 1779 Warning
When full speed range adaptive
cruise control is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
start to move. Always be 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 the full
speed range 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
near, medium or far.

Driving and operating189
Press E, the current setting is shown
in the Driver Information Centre.
Press E again to change the
following distance. The setting is also displayed in the Driver Information
Centre.The selected following distance is
indicated by filled distance bars in the
adaptive cruise control page.
Note that the following distance
setting is shared with the sensitivity
setting of forward collision alert
3 193.
Example: If setting 3 (far) is selected,
then the driver is warned sooner
before a possible collision, also if
adaptive cruise control is inactive or
switched off.
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
The green illuminated vehicle ahead
control indicator A is displayed when
the system detects a vehicle in the driving path. The range of the sensors
is between 25 and 150 metres
depending on vehicle speed.
Forward collision alert 3 193.

190Driving and operatingIf this symbol does not display, or
displays briefly, adaptive cruise
control will not respond to vehicles
ahead.
Deactivation
Adaptive cruise control is deactivated by the driver when:
● y is pressed.
● Brake pedal is applied.
● Clutch pedal is depressed for more than four seconds.
● Selector lever of automatic transmission is moved to N.
The system is also automatically
deactivated when:
● Vehicle speed accelerates above
190 km/h or slows down below
55 km/h (on vehicles with
automatic transmission it slows
down to a stop without
deactivating within five minutes).
● The Traction Control system is deactivated or operating.
● The Electronic Stability Control is
deactivated or operating.● There is no traffic and nothing detected on the road sides for
approx. one minute. In this case there are no radar echoes and
the sensor may report that it is
blocked.
● The active emergency braking system is applying the brakes.
● Driving on steep inclines.
● The radar sensor is blocked by an ice or water film.
● A fault is detected in the radar, camera, engine or brake system.
● The brakes are too hot.
Additionally, the system is
automatically deactivated on vehicles with automatic transmission (full
speed range adaptive cruise control)
when:
● The electric parking brake is applied.
● The vehicle is being held to a stop
by the system for more than
five minutes.
● The vehicle stops, the driver's seat belt is unbuckled and the
driver's door is opened.When adaptive cruise control is
deactivated, the control indicator m
changes from green to white and a
pop-up message is displayed in the
Driver Information Centre.
The stored speed is maintained.
On Midlevel display, the stored speed is indicated in brackets in the Driver
Information Centre when the system
is deactivated but not switched off.
On Uplevel display, the adaptive
cruise control symbol C changes
from green to white when the system
is deactivated but not switched off.
9 Warning
When adaptive cruise control is
deactivated, the driver must take
over full brake and engine control.

Driving and operating191Switching off
Press C to switch off adaptive cruise
control. C in the Driver Information
Centre extinguishes. The stored
speed is deleted.
Switching off the ignition also
switches off adaptive cruise control
and deletes the stored speed.
Driver's attention ● Use adaptive cruise control carefully on bends or mountainroads, 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 adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely thevisibility. In case of sensor
blockage, clean the sensor
cover.
System limits ● 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.
● Adaptive cruise control does ignore the oncoming traffic.
● Adaptive cruise control does not consider pedestrians and
animals for braking and driving off.
● Adaptive cruise control considers
stopped vehicles only at low
speed.● Do not use adaptive cruise control when towing a trailer.
● Do not use 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
longer detects any vehicle ahead,
then control indicator A will
extinguish.

Driving and operating195
The first button press shows the
current setting on the Driver
Information Centre. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed. The alert timing will vary based on vehicle speed. The faster
the vehicle speed, the farther away
the alert will occur. Consider traffic
and weather conditions when
selecting the alert timing.Note that the alert timing sensitivity
setting is shared with the following
distance setting of the adaptive cruise
control. So changing the alert timing
sensitivity changes the adaptive
cruise control following distance
setting.
Deactivation
The system can be deactivated.
On forward collision alert with radar
sensor the system can be disabled by the personalisation menu, 3 125.
On forward collision alert with front
camera press V repeatedly until
Forward Collision Alert Off appears in
the Driver Information Centre.
If the forward collision alert was
deactivated, alert sensitivity is set to
"medium" when ignition is switched on next time.
The last selected setting will be stored
when the ignition is switched off.
General information9 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.

Driving and operating1999Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Deactivation
On vehicles with front camera active
emergency braking can be
deactivated by repeatedly pressing
the gap switch V to Off setting,
3 193. If deactivated a message is
displayed in the Driver Information
Centre.
On vehicles with radar sensor the
system can be disabled in the
personalisation menu in the Info-
display, 3 125.
System limitations In some cases, the active emergencybraking 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.Emergency automatic braking may
not:
● detect a vehicle ahead on winding or hilly roads.
● detect all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detect a vehicle when weather limits visibility, such as in fog,rain, or snow.
To avoid malfunction keep the areas
of the camera sensor in the
windscreen and the radar sensor in
the radiator grille always clean from
dirt, dust, ice and snow.
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.

200Driving and operatingIf the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.

Parking assist General information
When the trailer hitch is attached,
change the configuration settings in
the vehicle personalisation menu in
the Info-Display. Vehicle
personalisation 3 125.
When attaching a trailer or bike
carrier to the trailer hitch, the parking
assist is deactivated.
Rear 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 rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system has four ultrasonic
parking sensors in the rear bumper.
Activation
After ignition is switched on, the rear
parking assist is activated.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
Indication
The system warns the driver with acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm while a forward gear is
engaged, or up to 1.5 metres while
reverse gear is engaged.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Driver
Information Centre 3 115.
The distance indication can be
inhibited by vehicle messages with a
higher priority. After dismissing the
message distance indication appears again.

202Driving and operating
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
If r is switched off within an ignition
cycle, the front parking assist is
deactivated. If vehicle speed has
exceeded 25 km/h beforehand,
parking assist will be reactivated when speed drops below 11 km/h.
When the system is deactivated, the
LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of the
vehicle in a distance range up to
80 cm and against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm while a forward gear is
engaged, or up to 1.5 m while reverse gear is engaged.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Driver
Information Centre 3 115 or,
depending on the version, on the Info- Display 3 121.
The distance indication can be
inhibited by vehicle messages with a
higher priority. After dismissing the
message distance indication appears
again.
Deactivation
