Braking and parking
Anti-lock brake system (ABS)
ABS pr e
vents the wheel
s from l
ocking up un-
der br
aking until the vehicle has reached a
virtual standstill. You can continue to steer the
vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal
pulsate while the ABS is working.
If the running gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited.
Hydraulic Brake Assist (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. This helps the
car to start moving, accelerate or climb a
gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph). To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected t
o excessive loads. The ve-
hicle can still be driven. The EDL will switch on
again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries
