correctly. EDL will switch on again automati -
cally when conditions have returned to nor-
mal.
Electronic inte raxle diff erential lock*/
selective w heel t orque cont rol*
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque
contro l (all wheel drive) operates when driving
through curves. The front whee l on the inside
of the curve or both wheels o n the inside of
the curve are braked selectively as needed .
This minimizes sliding in the front wheels and
a llows for more precise driving through
curves. The app licab le system may not acti-
vate when driving in wet or snowy conditions .
Post-collision brake assist
"Post-collision brake assist" can ass ist the
driver during a collision by reducing the dan-
ge r of slipp ing and further co llision and by au-
tomatic braking.
"Post-collision brake assist" functions during
front, side and rear collis ions when the a irbag
control module a detects a trigger level and
the co llision takes place at a dr iving speed
faster than 6 mph (10 km/h). The braking of
the vehicle happen automatically
via the ESC
as long as the ESC, the hydraulic brake sys-
tem, and the vehicle electrical system are not
damaged from the coll ision.
The fo llowing activ ities override the automat-
ic braking during a collision:
- If the dr iver presses the accelerator peda l.
There is no a utomatic braking.
- When t he force on the press brake pedal is
stronger than the braking force initiated by
the system . The vehicle is manually braked .
- When the ESC is damaged and the "post-
collision brake assist" is not availab le.
A
WARNING
- The ESC, ABS, ASR, EDL, electron ic inter-
axle d ifferential lock or select ive wheel
torque control cannot overcome the laws
of physics. This is espec ially important
on sl ippery o r wet roads. If the systems
begin acting to stabili ze your veh icle, you
should immediately alter your speed to
match the road and traffic conditions . Do
not let the increased safety prov ided
tempt you into tak ing risks. This could
increase your risk of a collision.
- Please note the risk of a collision increas-
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iving too close to objects ahead .
ESC, ABS, the brake assist system, EDL,
electronic interaxle differentia l lock or
selective whee l to rque control cannot
p revent coll isions.
- Press the acce lerator pedal carefully
when acce le rat ing o n even, slippe ry sur-
faces such as ice and snow. The drive
wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
col lis ion.

Tips
- ABS and ASR only function correc t ly
when all four wheels are eq uipped w ith
identical tires. Different t ire sizes can
lead to a reduction in engine power.
- You may hear noises when the systems
described are working .
- If the
