W et r
oads or r
oad salt
In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac-
tion could be delayed if the discs and pads
are damp, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
At high speed and with the windscreen wipers
activated, the brake pads will briefly touch
the brake discs. This takes place, although
unnoticeable to the driver, at regular intervals
to improve the response time of the brakes
when they are wet.
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven for
some distance without using the brakes when
there is a lot of salt on the road in winter. The
layer of salt that accumulates on the discs
and pads can be removed by gently apply-
ing the brakes a few times.
Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if rust
has formed on the disks, it is advisable to clean off the pads and disks by braking firmly
a few times at a moderately high speed

Braking and parking
Electronic differential lock (EDL)
When the EDL det ects wheel
spin, it brak
es
the spinning wheel and dir
ects 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 to 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
