154Driving and operatingRide control systems
Traction Control system
The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC) 3 154.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as control indicator b
extinguishes.
When TC operates b flashes.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 89.
Deactivation
TC can be switched off when spinning of drive wheels is required:
press b briefly to deactivate TC, k
illuminates. Deactivation is displayed
as status message in the Driver
Information Centre.
TC is reactivated by pressing b
again.
TC is also reactivated the next time
the ignition is switched on.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning. ESC operates in
combination with the Traction Control system (TC) 3 154.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational after each engine
start as soon as the control indicator
b extinguishes.

Driving and operating155When ESC operates b flashes.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 89.
Deactivation
For a more sporty behaviour ESC and
TC can be deactivated separately:
● Press b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates.
● Press and hold b for min. five
seconds: TC and ESC are
deactivated, k and n illuminate.
Additionally, the selected mode is
displayed as status message in the
Driver Information Centre.
If the vehicle comes into threshold
with deactivated ESP, the system will reactivate ESP for the time duration
of the threshold, when the brake
pedal is depressed once.
ESC is reactivated by pressing b
again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.Deactivation, VXR version
For very high-performance driving
ESC and TC can be deactivated
separately. The following modes are
selectable:
● Press b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates.
● Press b twice briefly within
2 seconds: TC is inactive, ESC is
operable without engine power
reduction, k and n illuminate.
● Hold b pressed for min.
5 seconds: TC and ESC are
completely inactive, k and n
illuminate.

Driving and operating159maintained. Control indicator m in
instrument cluster illuminates green.
Accelerator pedal can be released.
Vehicle speed can be increased by depressing 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 Press y; control indicator m in
instrument cluster illuminates white.
Cruise control is deactivated. Last
stored speed remains in memory for
later speed resume.
Automatic deactivation:
● Vehicle speed is below approx. 20 mph.
● Vehicle speed is above approx. 125 mph.
● The brake pedal is depressed.
● The clutch pedal is depressed for
a few seconds.
● Selector lever is in N.
● Engine speed is in a very low range.
● The Traction Control system (TC)
or Electronic Stability Control
(ESC) is operating.
Resume stored speed
Turn thumb wheel to RES/+ at a
speed above 20 mph. The stored
speed will be obtained.
Switching off
Press m; control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.

164Driving and operating
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.
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 in the
speedometer when the system
detects a vehicle in the driving path.
If this symbol does not display, or
displays briefly, adaptive cruise
control will not respond to vehicles
ahead.
Deactivation Adaptive cruise control is deactivatedby the driver when:
● y is pressed.
● The brake pedal is depressed.
● The clutch pedal is depressed for
more than four seconds.
● The gear selector lever of automatic transmission is moved
to N.
The system is also automatically
deactivated when:
● Vehicle speed slows down below
28 mph or accelerates above
120 mph.
● The Traction Control system (TC)
is operating for more than
20 seconds.
● The Electronic Stability Control (ESC) is operating.

Driving and operating165● There is no traffic and nothingdetected on the road sides for
several minutes. In this case,
there are no radar echoes and
the sensor may report that it is
blocked.
● The collision imminent braking system is applying the brakes.
● The radar sensor is blocked by an ice or water film.
● A fault is detected in the radar, engine or brake system.
When adaptive cruise control is
deactivated automatically, the control
indicator m illuminates white and a
warning symbol is displayed as a pop- up in the Driver Information Centre.
The stored speed is maintained.
9 Warning
When adaptive cruise control is
deactivated, the driver must take
over full brake and engine control.
Switching off
Press C to switch off adaptive cruise
control. The control indicator m
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 mountain
roads, as it can lose the vehicle
ahead and need 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.
● 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 limits ● The system's automatic brake force does not permit hard
braking and the braking level
may not be sufficient to avoid a
collision.
