Operation
front wheels are turned, the normal ABS is
activ at
ed.
Br
ake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, 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, braking assist au-
tomatically 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
››› page 205.
Electronic differential lock system (EDS)
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. T
o 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 (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving 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
desired 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
grou nd c
an result in loss of vehicle control
and serious injury to the driver and passen-
gers.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC, provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
law
s of physics. Even with ESC and other sys-
tems, slippery and wet roads will always be
dangerous.
● Driving to quickly on wet ground can result
in the wheels lo
sing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if
, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely eff
ective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for ex
ample on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. 204
Driver assistance systems
WARNING
The effectiveness of the ESC can be consider-
ably r
educed if other components and sys-
tems affecting driving dynamics are not main-
tained or are not functioning correctly. This
includes, among others, brakes, tyres and
other systems already mentioned.
● Remember that changing and fitting other
components
to the vehicle can affect opera-
tion of the ABS, BAS, ASL EDL and ESC.
● Changes to the vehicle suspension or using
unap
proved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASL EDL and
ESC, as well as their effectiveness.
● Likewise, the effectiveness of ESC depends
on the use of s
uitable tyres ››› page 284. Note
● To en s
ure that the ESC and ASR work prop-
erly, all four wheels must be fitted with iden-
tical tyres. Any differences in the rolling radi-
us of the tyres can cause the system to re-
duce engine power when this is not desired.
● If a malfunction should occur in the ABS,
the ESC, EDL and ASR w
ill also be out of ac-
tion.
● Noises may be heard while any of the
above sy
stems are operating. Switching ASR on and off

Introduction WARNING
The intelligent technology in the start assist
sys t
ems cannot change the laws of physics.
The improved comfort provided by start as-
sist systems should not prompt you to take
risks.
● Unintentional movements of the vehicle
coul
d cause serious injury.
● The start assist systems are not a replace-
ment for driv
er awareness.
● Always try to adapt the speed of the vehi-
cle and
your style of driving to the condition
of the ground or the road and to weather and
traffic conditions.
● The start assist system cannot keep the ve-
hicle s
tationary in all conditions on a gradi-
ent or cause it to brake on steep downhill
gradients, e.g. if the road is slippery or icy. 205

when the Aut
o Ho
l
d function is on.
When the Auto Hold function is on, this helps
the driver if they must regularly stop the vehi-
cle or if they must stop with the engine run-
ning for prolonged periods, for example, on
hills, before a traffic light or in traffic jams
with continuous stopping and starting.
The Auto Hold function automatically pre-
vents the vehicle from rolling away acciden-
tally when at a standstill, without the driver
having to keep his/her foot on the brake ped-
al.
When the system that detects that the vehi-
cle has stopped, the Auto Hold keeps the ve-
hicle at a standstill. The brake pedal can be
released. If the driver presses the brake pedal briefly or
the accel
erator to start off, the Auto Hold
function releases the brake once more. The
vehicle moves according to the gradient.
If any of the conditions necessary for the Au-
to Hold function change while the vehicle
stopped, the system is turned off as is the in-
dicator on the button ››› Fig. 206. The elec-
tronic parking brake engages where necessa-

em*
Intr oduction The parking distance warning system assists
the driv
er when p
ark
ing. When the vehicle
approaches an obstacle, forwards or back-
wards, an intermittent audible warning will
be heard, higher or lower depending on the
distance. The shorter the distance, the short-
er the intervals between tones. If the vehicle
is too close to the obstacle, the audible warn-
ing becomes constant.
If you continue to approach an obstacle when
the sound is continuous, this means the sys-
tem can no longer measure the distance.

The steering wheel turns quickly by itself
when park in
g using the park assist system.
Placing your hand between the steering
wheel spokes could lead to injuries. Note
● The park a
ssist system has its limitations.
For example, it is not possible to park on
tight bends using the park assist system.
● Even if the park assist system recognises
that ther
e is not enough space for parking
the vehicle, the instrument panel display will
still show this place. In this case, the parking
manoeuvre should not be requested.
● Changing gears between forward and re-
verse g
ears before indicated (that is, before
the signal from the parking sensor system)
the parking results may not be ideal.
● For parallel parking (parallel to the road), a
sound wi
ll tell the driver when they must
change from forward gears to reverse; the
signal from the parking sensor system does
not indicate changes of direction.
● The park assist can also be activated after-

symbol is also displayed. Press on the
brake pedal so that the steering can turn with
the vehicle at a standstill and thus reduce the
number of manoeuvres.
● A “suitable” parking space length is at
lea
st 1.1 m greater than the length of the ve-
hicle.
● If the results of the park assist system are
not as
good after changing the wheels, the
system must memorise the perimeter of the
new wheels. This process is performed auto-

1) Do not use the rear assist system in the fol-
lowing cases:
– If the vehicle has been overloaded at the rear.
– If the driver is not familiar with the system.
– If the rear lid is open.
– If the position and installation angle of the camera
have been changed, e.g. in a rear-end collision. Have a
specialised workshop check the system.
2) Optical illusions of the camera (examples)
The rear assist camera produces two-dimensional im-
ages. Any cracks in or objects protruding from the
ground or from other vehicles are more difficult to spot
or cannot be seen due to a lack of depth in the image
displayed.
Objects or other vehicles may seem to be closer or fur-
ther away than what they really are:
– On changing from a flat surface to a slope or gradient.
– On changing from a slope or gradient to a flat surface.
– If the vehicle has been overloaded at the rear.
– On approaching protruding objects. These objects
may be outside the angle of vision of the camera when
reversing.
