Press and hold the brake pedal fully. Do not
●
remove your foot from the brake pedal or re-
duce braking force!
Do not "pump" the brake pedal, or reduce
●
braking force!
Maintain vehicle direction when braking
●
fully.
When the brake pedal is released or when
●
the brake force is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
expect the ABS to reduce the braking dis-
tance under any circumstances. This dis-
tance will increase when driving on gravel, re-
cent snow or on icy and slippery ground.
When driving on loose ground, the all-terrain
configuration of the ABS is automatically
turned on. When ABS is activated, the front
wheels may lock briefly. This shortens the
braking distance in off-road situations as the
wheels are prevented from digging into loose
surfaces. All-terrain ABS only intervenes when
driving in a straight line. When the front
wheels are turned, the normal ABS is activa-
ted.
Brake assistance systems (BAS)
The brake assistance system may reduce the
required braking distance. The brake assis-
tance system boosts the braking force if you
press the brake pedal quickly in an emergen-
cy. As a result, the braking pressure increases
Start and driving
rapidly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively.
Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, brake assist auto-
matically turns off the brake servo.
Traction control when accelerating (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. The ASR makes
some situations easier, for example, when
starting, accelerating or going uphill, even in
unfavourable road conditions.
The ASR can be switched on or off manually

Electronic differential lock system (EDL)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel
and directs the power to the other drive
wheels. To prevent the disc brake of the
braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive
loads. The EDL will switch on again automati-
cally when the brake has cooled down.
Electronic drive torque management
(XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In this
way, the wheel that is turning faster (outer
wheel) receives less drive torque than the in-
ner wheel. This may mean that in certain sit-
uations the torque delivered to the inner
wheel is too high, causing the wheels to spin.
On the other hand, the outer wheel is receiv-
ing a lower drive torque than it could transmit.
This causes an overall loss of lateral grip on
the front axle, resulting in understeer or
"lengthening" of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's de-
sired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected.
WARNING
Driving at high speed on icy, slippery wet
ground can result in loss of vehicle control
and serious injury to the driver and passen-
gers.
Adjust your speed and driving style to vis-
●
ibility, road, traffic and weather conditions.
