Stabilisation 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.
Reduced braking effect
Damp, frozen, salt-affected or corroded brakes can
impair the braking effect.
Clean the brakes by braking several times if traffic
conditions allow it.

When the engine is stopped, the brake booster
does not work
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.
Depress the brake pedal more forcefully.

Antilock braking system (ABS)
WARNING
Risk of accident!
An insufficiently released parking brake will impair
the function of the brake system.
ABS helps maintain control of the vehicle during
emergency braking. An ABS intervention is noticea-
ble by pulsating movements of the brake pedal.
Fully release the parking brake before driving.

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.
To back up
Pull the lever up to the
stop position.

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.
To solve
Pull the lever up a little and push in the lock button.

Press and hold the lock button and pull the lever
completely down.
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.
✓ The impact speed was greater than 10 km/h.
