Driving and operating137Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The Cruise control can store and
maintain speeds of approx. 20 to
120 mph. Deviations from the stored
speeds may occur when driving uphill or downhill.
For safety reasons, the cruise controlcannot be activated until the foot
brake has been operated once.
Activating in first gear is not possible.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With automatic transmission, only
activate cruise control in automatic
mode.
Control indicator m 3 89.
Switching on
Press m: control indicator m in
instrument cluster illuminates white.
Activation
Accelerate 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/-.
138Driving and operating
Reduce speedWith 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 resumed.
Switching off
Press m: control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Pressing L for activating speed
limiter or switching off the ignition also switches off cruise control and
deletes the stored speed.
Speed limiter The speed limiter prevents thevehicle exceeding a preset maximum
speed.
The maximum speed can be set at a
speed above 15 mph.
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 top line of the Driver Information
Centre (DIC) when the system is
active.
Activation
Press L. If cruise control or adaptive
cruise control has been activated
before, it is switched off when speed
limiter is activated and control
indicator m extinguishes.
Driving and operating139
Set speed limit
With speed limiter active, hold thumb
wheel turned to RES/+ or briefly turn
to RES/+ repeatedly until the desired
maximum speed is displayed in the
DIC.
Alternatively accelerate to the desired speed and briefly turn thumb wheel to SET/- : the current speed is stored as
maximum speed. Speed limit is
displayed in the DIC.Change speed limit
With speed limiter active, turn thumb
wheel to RES/+ to increase or SET/-
to decrease the desired maximum
speed.
Exceeding the speed limit
In the event of an emergency, it is possible to exceed the speed limit by
depressing the accelerator pedal
firmly beyond the point of resistance.
The limited speed will flash in the DIC and a chime sounds during this
period.
Release the accelerator pedal and the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation Press y: speed limiter is deactivated
and the vehicle can be driven without
speed limit.
The limited speed is stored and a
corresponding message appears in
the DIC.Resume limit speed
Turn thumb wheel to RES/+. The
stored speed limit will be obtained.
Switching off Press L, the speed limit indication in
the DIC extinguishes. The stored
speed is deleted.
By pressing m to activate cruise
control or adaptive cruise control or
by switching off the ignition, speed
limiter is also deactivated and the
stored speed is deleted.
