Driving and operating175Deactivation
ESC and TC can be deactivated:● hold b pressed for a minimum of
five seconds: ESC and TC are
both deactivated. k and n
illuminate and status messages appear in the Driver Information
Centre.
● To deactivate only Traction control system press button b
briefly: TC is inactive but ESC
remains active, k illuminates. A
status message appears in the
Driver Information Centre when
TC is deactivated.
ESC is reactivated by pressing the
b button again. If the TC system was
previously disabled, both TC and
ESC are reactivated. k and n
extinguishes when TC and ESC are
reactivated.
ESC is also reactivated the next time
the ignition is switched on.
Fault
If there is a fault in the system the
control indicator b illuminates
continuously and a message appears in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied
by a workshop.
Driving and operating177Vehicle speed can be increased bydepressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed
is resumed.
Cruise control remains activated
while gearshifting.
Increase speed
With cruise control active, hold thumb wheel turned to RES/+ or briefly turn
to RES/+ repeatedly: speed
increases continuously or in small
increments.
Alternatively accelerate to the desired speed and store by turning to SET/-.Reduce speed
With cruise control active, hold thumb
wheel turned to SET/- or briefly turn to
SET/- repeatedly: speed decreases
continuously or in small increments.
Deactivation of the functionality
Press y; control indicator m in
instrument cluster illuminates white.
On Uplevel display m changes to
white.
Cruise control is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Automatic deactivation: ● Vehicle speed is below approx. 30 km/h.
● Vehicle speed drops more than 25 km/h below the set speed.
● The brake pedal is depressed.
● The clutch pedal is depressed for
a few seconds.
● The selector lever is in N.
● Engine speed is in a very low range.● The Traction Control system orElectronic Stability Control is
operating.
● Parking brake is applied.
● Simultaneous pressing RES/+
and brake pedal deactivates
cruise control and will delete stored speed.
Resume stored speed
Turn thumb wheel to RES/+ at a
speed above 30 km/h. The stored
speed will be obtained.
Switching off the system
Press m, control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Pressing L to activate the speed
limiter or switching off the ignition also switches off cruise control and
deletes the stored speed.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed.
Driving and operating1839Warning
The Driver accepts full
responsibility to drive with the
appropriate following distance
based on traffic, weather, visibility and regional regulation. Followingdistance 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 m depending
on vehicle speed.
Forward collision alert 3 187.
If this symbol does not display, or
displays briefly, adaptive cruise
control will not respond to vehicles
ahead.
Deactivation of the functionality
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 . Vehicles with automatic
transmission slows down to a
stop without deactivating within
5 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 forapprox. 1 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 need to cool down.
Additionally, the system is
automatically deactivated on vehicles with automatic transmission (full
speed range adaptive cruise control)
when:
● The incline uphill or downhill is greater than 20%.
● The electric parking brake is applied.
184Driving and operating●The vehicle is being held to a stop
by the system for more than
5 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 C
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
immediately.
Switching off the system
Press v to switch off adaptive cruise
control. The control indicator C
extinguishes in the Driver Information Centre. 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 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 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 the
visibility. In case of sensor
blockage, clean the sensor
cover.
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.
