Driving and operating175Deactivation
ESC and TC can be deactivated:● hold t pressed for a minimum of
five seconds: ESC and TC are
both deactivated. k and t
illuminate and status messages appear in the Driver Information Centre.
● To deactivate only Traction control system press button t
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 t
button again. If the TC system was
previously disabled, both TC and
ESC are reactivated. k and t
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.
Interactive driving system Flex Ride Flex Ride driving system allows thedriver to select between three driving
modes:
● SPORT mode: press SPORT,
LED illuminates.
● TOUR mode: press TOUR, LED
illuminates.
● AUTO mode: neither SPORT nor
TOUR is pressed, no LED
illuminates.
Deactivate SPORT mode or TOUR
mode by pressing corresponding
button once more.
In each driving mode Flex Ride
adjusts the following electronic
systems:
● electronic damping control
● accelerator pedal control
● electronic power steering control
● automatic transmission
180Driving and operating● 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
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.The maximum speed can be set at
speeds above 25 km/h up to
200 km/h.
The driver can only accelerate up to
the preset speed. Deviations from the
limited speed may occur when driving
downhill.
The preset speed limit is displayed in
the Driver Information Centre when
the system is active.
Activation
Illustrations show different versions.
Press L, symbol L illuminates in the
Driver Information Centre.
If cruise control has been activated
before, it is switched off when speed
limiter is activated and the control
indicator m extinguishes.
Set speed limit
Accelerate to the desired speed and
briefly turn thumb wheel to SET/-: the
current speed is stored as maximum speed.
On Baselevel display L and the
speed limit is displayed.
186Driving and operatingDeactivation
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
25 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
immediately.
Switching off
Press C to switch off adaptive cruise
control. C in the Driver Information
Centre extinguishes. The stored
speed is deleted.
Driving and operating187Switching 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 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.
● 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.
