Driving and operating163ResettingIf b illuminates and remains
illuminated, reset the system as
follows:
1. Stop the vehicle.
2. Switch off the vehicle and wait for
15 seconds.
3. Switch on the vehicle. If b still illuminates and remains
illuminated, seek the assistance
of a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds of approx. 25 km/h
or more.
Deviations from the stored speeds may occur when driving uphill or
downhill.
With the Traction Control system or
Electronic Stability Control, the
system may limit wheel spin while
using cruise control. If this happens,
the cruise control will automatically
disengage.
Traction Control system 3 161.
Electronic Stability Control 3 162.
If a collision alert occurs when cruise
control is activated, cruise control is
disengaged.
Forward collision alert 3 166.
Do not use the cruise control if it is not
advisable to maintain a constant
speed.
164Driving and operatingSwitching on the system
Press m, control indicator m in
instrument cluster illuminates white
and cruise control is on standby.
Press m again to deactivate cruise
control.
Activation of the functionality Accelerate to the desired speed and
press SET/-, the current speed is
stored and maintained. The desired set speed briefly appears in the
instrument cluster. 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.
Control indicator m 3 81.
Increase speed
With cruise control active, press
RES/+ until the desired speed is
reached or press RES/+ repeatedly:
speed is increased in small
increments.
Reduce speed
With cruise control active, press SET/- until the desired speed is
reached or press SET/- repeatedly:
speed is decreased in small
increments.
Resume speedIf the cruise control is set at a desired speed and then the brakes are
applied, the cruise control is
disengaged without erasing the set
speed from memory. Once the
vehicle speed is approx. 25 km/h or
higher, press RES/+. The vehicle returns to the previously set speed.
Deactivation of the functionality
Press y, control indicator m in
instrument cluster illuminates white.Cruise control is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Automatic deactivation: ● Vehicle speed is below approx. 25 km/h.
● The brake pedal is depressed.
● The selector lever is in N.
● The Traction Control system or Electronic Stability Control is
operating.
Switching off the system
Press m, control indicator m in
instrument cluster extinguishes. The stored speed is deleted.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed.
The maximum speed can be set at
speeds above 25 km/h.
Driving and operating165The 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 Driver Information Centre when
the system is active.
Activation of the functionality
Press L.
If cruise control has been activated
beforehand, it is switched off when
speed limiter is activated and the
control indicator m extinguishes.
Set speed limit
Accelerate to the desired speed and
briefly press SET/-: the current speed
is stored as maximum speed.
Speed limit is displayed in the Driver
Information Centre.
Change speed limit
With speed limiter active, press
RES/+ to increase or SET/- to
decrease the desired maximum
speed.
Exceeding the speed limit
When exceeding the limited speed
without driver input, the speed will
flash in the Driver Information Centre
and a chime sounds during this
period.
In the event of an emergency, it is
possible to exceed the speed limit by
depressing the accelerator pedal
firmly nearly to the final point. In this
case no chime sounds.
Release the accelerator pedal and
the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation of the functionality
The limited speed will be stored and
is indicated in brackets in the Driver
Information Centre. Additionally, a
corresponding message appears.
Speed limiter is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
166Driving and operatingResume limit speed
Press RES/+ . The stored speed limit
will be obtained.
Switching off the system
Press L, the speed limit indication
extinguishes in the Driver Information Centre. The stored speed is deleted.
By pressing m to activate cruise
control or adaptive cruise control,
speed limiter is also deactivated and
the stored speed is deleted.
By switching off the vehicle, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.
Forward collision alert The forward collision alert may help to
avoid or reduce the harm caused by
front-end crashes.
The 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 m.
A vehicle ahead is indicated by the
control indicator A.
If a vehicle directly ahead is
approached too quickly, a warning
chime is sounded.
Additionally, the driver is notified by a flashing red LED stripe which is
projected on the windscreen in the
driver's field of view.
A precondition is that forward collision alert is not deactivated in the vehicle
personalisation 3 90.
Activation
Forward collision alert operates
automatically above 8 km/h, if it is not deactivated in the vehicle
personalisation menu.
Alerting the driver
The vehicle ahead control indicator
A illuminates green in the instrument
cluster when the system has detected
a vehicle in the driving path.
The control indicator A changes to
yellow when the distance to a
preceding moving vehicle gets too
small or when approaching another
vehicle too rapidly.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.
When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, the driver
is notified by a flashing red LED stripe which is projected on the windscreen
in the driver's field of view.
172Driving and operatingThe front pedestrian protection
system can detect and alert about
pedestrians when in a forward gear at
speeds between 8 km/h and
80 km/h.
Additionally, the front pedestrian protection system can provide a
boost to braking or automatically
brake the vehicle.
During daytime driving, the system
detects pedestrians up to a distance
of approximately 40 m. During
nighttime driving, system
performance might be limited.
The front pedestrian protection can
be set to Off, Alert or Alert and
Brake in the vehicle personalisation
3 90.9 Danger
Front pedestrian braking does not
provide an alert or automatically
brake the vehicle, unless it detects
a pedestrian.
The system may not detect
pedestrians, including children,
when the pedestrian is not directly
ahead, not fully visible, not
standing upright, or when part of a
group.
Front pedestrian protection includes:
● detecting front pedestrian ahead● front pedestrian alert
● automatic braking
Pedestrian detected ahead
A pedestrian ahead is indicated up to
a distance of approximately 40 m by control indicator 7 in the instrument
cluster.
Front pedestrian alert
When the vehicle approaches a
detected pedestrian ahead too
rapidly, a red flashing LED alert is projected onto the windscreen in the
driver's field of view and a warning
chime is sounded. The brake system
may prepare for driver braking to
occur more rapidly which can cause a
brief, mild deceleration. Continue to
apply the brake pedal as required.
Cruise control may be disengaged
when the front pedestrian alert
occurs.
