Driver assist systems
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.
flashing - 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.
flashing - 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 keep control the vehicle when down-
shifting or abruptly decelerating, e.g. on an icy road
surface. If the drive wheels lock, MSR increases the
engine speed. As a result, the braking effect of the
engine is reduced and the wheels can turn freely
again.
Electronic Differential Lock (EDL)
EDL helps to stabilize the vehicle when driving on
road surfaces with different grip under the individual
wheels. EDL brakes a spinning wheel and transmits
power to a different drive wheel.
Electronic Differential Lock (XDL+)
XDL + helps to stabilize the vehicle during fast cor-
nering by braking the inside wheel of the driven axle.
Hill Hold Control
Hill Hold Control helps when starting off on uphill
gradients by braking the vehicle for about 2 seconds
after the brake pedal is released.
Operating conditions
✓ The gradient is at least 5%.
✓ The driver's door is closed.
Multi-Collision Brake (MCB)
MCB helps to decelerate and stabilize the vehicle af-
ter a collision with an obstacle. This reduces the risk
of further collisions.
Operating conditions
✓ There has been a frontal, side and rear collision of
a certain severity.
