Driving and operating155Ride control systems
Traction Control system The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC) 3 155.
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 90.
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) 3 155.
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.

156Driving and operatingWhen 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 90.
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, OPC 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 two
seconds: TC is inactive, ESC is
operable without engine power
reduction, k and n illuminate.
● Press and hold b for min. five
seconds: TC and ESC are
completely inactive, k and n
illuminate.

160Driving and operatingmaintained. 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. 30 km/h.
● Vehicle speed is above approx. 200 km/h.
● 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 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.
