Driver assistance systems
Electronic differential lock (XDS)* When taking a curve, the driveshaft differen-
tial
mec
hanism 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 or the ESC is
in Sport mode.
Brake servo The brake servo increases the pressure you
ap
p
ly
to the brake pedal. It works only when
the engine is running . If the brake servo is not functioning, e.g. due
to a malf
unction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
ext ern
al factors.
● Never let the vehicle coast with the engine
switc
hed off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the
vehicle is being towed, you will
have to press the brake pedal considerably
harder than normal. Start-Stop System*
D e
s
cription and operation The Start-Stop function stops the engine
when the
v
ehic
le is stopped and starts it au-
tomatically when required.
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutral and r
elease the clutch pedal. The
engine will switch off. The warning lamp will appear on the instrument panel dis-
pla
y.
– When the clutch pedal is pressed the en-
gine wil
l start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox – Use the foot brake to bring the vehicle to a
stop and k
eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp will appear in the
display.
– When you take your foot off the brake pedal
the engine wi
ll start up again. The warning
lamp will switch off.

Star
t-Stop function interruption
In the following situations, the Start-Stop
function will be interrupted and the engine
will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in
a row
.
● The battery has been discharged excessive-
ly.
● The St
art-Stop System is manually deacti-
vated.
● The w
indscreen de-mist function is turned
on.
● The temperature of the interior exceeds the
comfor
t limits ( A/C button).
● If the airflow is increased by more than 3
pr e
s
ses.
● Temperature setting HI or LO is sel
ected.●
The engine coo
lant temperature is insuffi-
cient.
● The alternator is faulty, for example the V-
belt ha
s ruptured.
● If any of the conditions described in the
previou
s section are not fulfilled.
When the engine is turned off by the Start-
Stop function, this is displayed on the instru-
ment panel.
If the Start-Stop system is not switched on,
the warning lamp will appear on the instru-
ment panel. WARNING
Never allow the vehicle to move with the en-
gine off f or an
y reason. You could lose control
of your vehicle. This could cause an accident
and serious injury.
● The brake servo does not work with the en-
gine off. Y
ou need more force to stop the vehi-
cle.
● Power steering does not work when the en-
gine is not
running. That is why it is much
more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving
through wat
er (fording streams, etc.). Note
● For v
ehicles with the Start-Stop function
and a manual gearbox, when the engine is
started, the clutch must be pressed. ●
When the condition s
for the Start-Stop
function are not fulfilled, the instrument pan-
el displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than
270°, it wi
ll not be possible to start the vehi-
cle again. To start the vehicle, straighten the
steering wheel so that it is turned less than
270°.
● There are different versions of the dash

table on page 2
The Tiredness detection informs the driver
when their driving behaviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Tired-
nes s
detection system tempt you into taking
any risks when driving. Take regular breaks, sufficient in length when making long jour-
neys.
●
The driv er a
lways assumes the responsibil-
ity of driv
ing to their full capacity.
● Never drive if you are tired.
● The system does not detect the tiredness of
the driver in al
l circumstances. Consult the in-
formation in the section ››› page 176, System
limitations.
● In some situations, the system may incor-
rectly int
erpret an intended driving manoeu-
vre as driver tiredness.
● No warning is given in the event of the ef-
fect c
alled microsleep!
● Please observe the indications on the in-
strument p
anel and act as is necessary. Note
● Tiredne s
s detection has been developed for
driving on motorways and well paved roads
only.
● If there is a fault in the system, have it
check
ed by a specialised workshop. Function and operation

s
s detection symbol. Tiredness detection determines the driving
beh
av
iour of
the driver when starting a jour-
ney, making a calculation of tiredness. This is
constantly compared with the current driving
behaviour. If the system detects that the driv-
er is tired, an audible warning is given with a
sound and an optic warning is shown with a
symbol and complementary message on the
instrument panel display ››› Fig. 175. The
message on the instrument panel display is
shown for approximately 5 seconds, and de-
pending on the case, is repeated. The system
stores the last message displayed.
The message on the instrument panel display
can be switched off by pressing the button on the windscreen wiper lever or the
b
utt
