Overview
the START-STOPP system.
✓ Auto Hold is activated.
Stabilisation control (ESC)
✓
The automatic transmission mode is not selec-
ted.
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.

NOTICE
Disable Auto Hold to allow the vehicle to roll if nec-
essary when driving through a car wash.
Traction control (TCS)
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
Antilock 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. This reduces the braking effect of the
engine and the wheels can rotate 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.
Active steering assistance (DSR)
In difficult situations, the DSR provides the driver
with a steering recommendation in order to stabilise
the vehicle.
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.
