and ESC Sport mode on and off or in the Infotain-
ment system.
Be sure to switch ASR on again when you no longer
need less traction.
Anti-Lock Brake System (ABS)
ABS helps to keep the wheels from locking up and
helps to maintain the driver's ability to steer and
control the vehicle. This means the vehicle is less
likely to skid, even during hard braking:
— Push the brake pedal down hard and hold it there.
Don't take your foot off the pedal or reduce the
force on the pedal!
— Do not "pump" the brake pedal or let up on it!
— Steer the vehicle while pushing down hard on the
brake pedal.
— ABS stops working if you release or let up on the
brake.
When ABS is doing its job, you will notice a slight vi-
bration through the brake pedal and hear a noise.
ABS cannot shorten the stopping distance under all
conditions. The stopping distance may even be lon-
ger, for instance, when driving on gravel or on newly
fallen snow covering an icy or slippery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping
distances. If you press the brake pedal very quickly,
BAS detects an emergency situation. It then very
quickly builds up full brake system pressure, maxi-
mizing braking power and reducing the stopping dis-
tance. This way, ABS can be activated more quickly
and efficiently.
Do not reduce pressure on the brake pedal! BAS
switches off automatically as soon as you release or
let up on the brake.
Anti-Slip Regulation (ASR)
ASR reduces engine power directed to spinning
wheels and adjusts power to the road conditions.
Even under poor road conditions, ASR can make it
easier to get moving, accelerate, and climb hills.
ASR can be switched on and off manually
→ page 193, Switching Anti-Slip Regulation (ASR)
and ESC Sport mode on and off.
Electronic Differential Lock (EDL and XDL)
EDL is applied during regular straight-line accelera-
tion. EDL gently brakes a drive wheel that has lost
traction (spinning) and redirects the drive force to
other drive wheels. In extreme cases, EDL automati-
cally switches off to keep the brake from overheat-
ing. As soon as the brake has cooled down, EDL au-
tomatically switches on again.
192 Parking and maneuvering
XDL is an extension of the Electronic Differential
Lock system. XDL does not react to drive wheel slip-
page when driving straight ahead. Instead, XDL de-
tects slippage of the inside front wheel during fast
cornering. XDL applies enough brake pressure to this
wheel in order to stop the slippage. This improves
traction, which helps the vehicle stay on track.
Automatic Post-Collision Braking System
In an accident, the Automatic Post-Collision Braking
System can help the driver to reduce the risk of skid-
ding and the danger of secondary collisions through
automatic braking.
The Automatic Post-Collision Braking System only
works in collisions if the airbag control unit registers
the corresponding triggering threshold during the
accident, and the accident occurs at a speed greater
than 6 mph (10 km/h).
The ESC brakes the vehicle automatically, provided
that the hydraulic braking system, the ESC, and the
electrical system are undamaged and still work
properly.
The following actions override automatic braking in
the event of an accident:
— When the driver depresses the accelerator. No au-
tomatic braking occurs.
— When the brake pressure transmitted through the
depressed brake pedal is greater than the brake

pressure provided by the system. The vehicle is
braked manually.
Driving fast on icy, slippery, or wet roads can lead
to a loss of control and result in serious personal
injury for you and your passengers.
·
Always adjust your speed and driving style to
road, traffic, weather, and visibility conditions.
Never let the additional safety that ESC, ABS,
BAS, ASR, and EDL can provide tempt you into
taking extra risks.
·
Braking assistance systems cannot overcome
the laws of physics and always prevent loss of
vehicle control. Slippery and wet roads are still
dangerous even with ESC and the other sys-
tems!
·
Driving too fast on wet roads can cause the
wheels to lose contact with the road and "hy-
droplane." A vehicle that has lost road contact
cannot be braked, steered, or controlled.
·
These systems cannot reduce the risk of acci-
dent, for example if you drive too fast for condi-
tions or if you do not keep your distance from
the vehicle in front of you.
