Braking and stabilising systems Overview
Electronic Stability Control (ESC)
ESC helps to stabilize the vehicle in borderline situa-
tions (e.g. when the vehicle starts to skid). ESC
brakes the individual wheels to maintain the direc-
tion of travel.
flashes - ESC is engaged
Anti-Slip Regulation (ASR)
ASR helps to stabilize the vehicle when accelerating
or driving on low-grip roads. ASR reduces the drive
power transmitted to the wheels when the wheels
spin.
flashes - ASR is engaged
Anti-lock Braking System (ABS)
ABS helps maintain control of the vehicle during
emergency braking. An ABS intervention is noticea-
ble by pulsating movements of the brake pedal.
Motor Slip Regulation (MSR)
MSR helps to maintain control of the vehicle in the
event of a sudden reduction in speed, e.g. on icy
roads. If the drive wheels lock, MSR increases the
engine speed. As a result, the braking e

Risk of collision in a speed range of 30-60 km/h
The system warns of a collision hazard first. If the
driver does not respond, the vehicle is automatically
braked.
Operating conditions
q Front Assist activated.
q Driving speed between 5-60 km/h.
Speed limiter Functionality
The speed limiter controls the maximum driving
speed according to the set speed limit.
If the limit is exceeded when driving downhill, brake
the vehicle with the brake pedal.

Operating conditions
q The driving speed is higher than 30 km/h.

Lane change assist system Side AssistUsage
Side Assist monitors the area both beside and behindthe vehicle.
The system uses optical signals in the exterior mirror
to alert the driver to vehicles that could be danger-
ous when changing lanes.
Functionality
The system warns of an approaching vehicle through
the illumination of the indicator light in the exteri-
or mirror cover on the vehicle side where the vehicle
is detected.
Driving situations in which a system warning oc-
curs
Your vehicle is overtaken by vehicle

. The faster

A
approaches, the sooner the warning is giv-
en by the indicator light.
Vehicle
B
is overtaken by your vehicle at a speed
that is faster by max. 10 km/h. If the speed is higher
during the overtaking process, no warning will be
provided by the indicator light.
Indicator light
illuminated - There is another vehicle behind your
vehicle
flashing - There is another vehicle behind your ve-
hicle, and the turn signal on the same side is switch-
ed on
For vehicles with Lane Assist, the indicator light will
also flash if your vehicle crosses the lane markings in
the direction of the approaching vehicle. The system
will trigger a steering wheel vibration in this case.
For this, Lane Assist must be activated and the lane
marking between the vehicles must be detected.
Operating conditions
q The driving speed is higher than 15 km/h.
q No accessories are connected to the trailer sock-
et.
Function restriction
The system cannot detect lane width. For this rea-
son, it may, for example, draw attention to a vehicle
in a distant lane in the following cases.
