Driving and operating179Driver 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 control cannot be activated until the foot
brake has been operated once.
Activation 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 3 116.
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/-.
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.
180Driving and operatingDeactivation
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 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 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 the
vehicle 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 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 the control
indicator m extinguishes.
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
Driver Information Centre.
Alternatively accelerate to the desired speed and briefly turn thumb wheel to SET/- : the current speed is stored as
190Driving and operatingAlerting the driver
A green illuminated vehicle ahead
control indicator A illuminates in the
instrument cluster when the system has detected a vehicle in the driving
path. When the distance to a
preceding moving vehicle gets too
small or when approaching another
vehicle too rapidly and a collision is
imminent, the collision alert symbol
pops-up in the Driver Information
Centre. Simultaneously a warning
chime sounds.
Depress the brake pedal, if it is
required by the situation.
Settings
Settings can be changed in the Auto
collision preparation menu in the
vehicle personalisation 3 129.
Forward collision alert based on
front camera system
Forward collision alert uses the front
camera system in the windscreen to
detect a vehicle directly ahead, in
your path, within a distance of approx.
60 metres.
Activation
Forward collision alert operates
automatically above 25 mph, if it is not deactivated by pressing V, see
below.
Selecting the alert sensitivity
The alert sensitivity can be set to
near, medium or far.
Press V; the current setting is shown
in the Driver Information Centre.
Press V again to change the alert
sensitivity.
Driving and operating191Alerting the driver
A green illuminated vehicle ahead
control indicator A illuminates in the
instrument cluster when the system
has detected a vehicle in the driving
path.
When the distance to a preceding
moving vehicle gets too small or when
approaching another vehicle too
rapidly and a collision is imminent, the
collision alert symbol pops-up in the
Driver Information Centre.
Simultaneously a warning chime
sounds. Depress the brake pedal, if it is required by the situation.
Deactivation
The system can be deactivated.
Press V repeatedly until the following
message appears in the Driver
Information Centre.
General information for both
variants of forward collision alert
9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also onother metallic objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage
