Driving and operating173
Apply electric parking brake: pull and
hold the switch m for more than
5 seconds. If control indicator m
illuminates, electric parking brake is
applied.
Release electric parking brake: push
and hold the switch m for more than
2 seconds. If control indicator m
extinguishes, electric parking brake is
released.
Control indicator m flashes: electric
parking brake is not fully applied or
released. When continuously
flashing, release electric parking
brake and retry applying.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.Hill start assist
The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
The hill start assist is not active during
an Autostop.Ride control systems
Traction Control system
The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC) 3 174.
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 the control indicator
b extinguishes.
When TC operates b flashes.

174Driving and operating9Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 115.
Deactivation
TC can be switched off when spinning of drive wheels is required:
press button b briefly to deactivate
TC, k illuminates. Deactivation is
displayed as status message in the
Driver Information Centre.
TC is reactivated by pressing the b
button 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) 3 173.
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.
When 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 3 115.
Deactivation

Driving and operating175
For a more sporty behaviour ESC and
TC can be deactivated separately:
■ press button b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates
■ hold button b pressed for min.
5 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 the
b button 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 button b briefly: only Traction
control system is inactive, ESC
remains active, k illuminates
■ press button b twice briefly within
2 seconds: TC is inactive, ESC is
operable without engine power
reduction, k and n illuminate
■ hold button b pressed for min.
5 seconds: TC and ESC are
completely inactive, k and n
illuminate.
Additionally the selected mode is
displayed as status message in the
Driver Information Centre.
On VXR version TC and ESC remain
deactivated even if the vehicle comes into threshold with unstable
driveability.
ESC is reactivated by pressing the
b button 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.

Driving and operating179
ActivationAccelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
maintained. 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 button y, control indicator m in
instrument cluster illuminates white.
Cruise control is deactivated. Last
used set speed is stored in memory
for later speed resume.
Automatic deactivation:
■ vehicle speed below approx. 20 mph,
■ vehicle speed above approx. 125 mph,
■ the brake pedal is depressed,
■ the clutch pedal is depressed for a few seconds,
■ selector lever in N,
■ engine speed in a very low range,
■ the Traction Control system or Electronic Stability Control 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 button m, control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Pressing button L for activating
speed limiter or switching off the
ignition also switches off cruise
control and deletes the stored speed.

184Driving 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 deactivated
by the driver when:
■ button y is pressed,
■ brake pedal is applied,
■ clutch pedal is depressed for more than four seconds,
■ 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,
■ Traction Control system is operating for more than
20 seconds,
