Driving
Advance warning
If the syst em det
ects a possible collision with
the vehicle in front, it alerts the driver by
means of an audible warning and an indica-
tion on the instrument panel display {
››› Fig. 176.
The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking ››› in Intro-
duction on page 2 49

.
When Front Assist is connected, the indica-
tions of other functions on the screen may be
hidden.
Critical warning
If the driver fails to react to the advance
warning, the system may actively intervene
in the brakes and generate a brief jolt to warn
the driver of the imminent danger of a colli-
sion.
Automatic braking
If the driver also fails to react to the critical
warning, the system may initiate independ-
ent emergency braking by progressively in-
creasing the braking in accordance with the
criticality of the situation. Driver emergency braking assistance sys-
tem
If the driv

er, after the critical warning, starts
braking but the system detects that the brake
is not being applied with sufficient force, the
braking intensity will be increased. This brake
assist only occurs if the pedal is pressed firm-
ly. WARNING

Driver assistance systems
Limitations
This syst em does not r
eact to objects that
cross transversely or to animals. The basic
limitations of the Front Assist must also be
taken into account ››› page 251
.
Turn assist Turn assist can avoid a collision with a vehicle
appr
oaching in the opposit

e direction, by
braking the vehicle itself when the intention is
to turn.
This system is active up to 15 km/h (9 mph).
Limitations
The turn-off assist function is available if you
have indicated your intention to turn by acti-
vating the turn signal, you have turned the
steering wheel and the turning path has star-
ted.
It only reacts to vehicles that are in the path
of the vehicle (not to animals, people, etc.).
The basic limitations of the Front Assist must
also be taken into account ››› page 251

-calibration indication. Front Assist has certain limitations inherent to
the syst
em. Thus, in cert

ain circumstances,
some of the reactions may be inappropriate
from the driver's standpoint. So pay attention
in order to intervene if necessary.
The following conditions may cause the
Front Assist not to react or to do so too
late:

Braking and parking
Brake assist systems Electronic Stability Control (ESC)
The ESC helps t
o impr
ove safety. It reduces
the tendency to skid and improves the stabili-
ty and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening !.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (TCS), electronic dif-
ferential lock (EDS), electronic torque control
(XDS) and the tractor-trailer sway mitiga-
tion*.
ESC also helps stabilise the vehicle by
changing the torque.
The TCS can be deactivated when wheel
spin is desirable ››› page 281
.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer the
vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal
pulsate while the ABS is working. If the running gear or brake system is modi-
fied, the eff
ectiv

eness of the ABS could be se-
verely limited.
Hydraulic Brake Assist (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control (TCS)
In the event of the wheels spinning, the TCS
reduces the engine torque to adapt to the
road condition. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs 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 vehicl
e 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 ››› page 303
.
Electronic engine torque management
(XDS)
When taking a curve, the driveshaft differen-
tial 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) re-
ceives 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 can
cause a loss of grip on the drive axle, in this
case the front axle, which results in under-
steer or “lengthening” of the trajectory.
The XDS 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 requested
trajectory is much more precise. »

The P ark Assist syst
em cannot be switched
on if the factory-fitted towing bracket
››› page 298 is electrically connected to a
trailer.
After changing a wheel
If, after changing a wheel, the vehicle stops
entering and exiting parking spaces correct-
ly, the circumference of the new wheel may
be different and the system may need to
adapt to it. The adaptation is automatic and
takes place during driving. Making turns slow-
ly and in both directions (20 km/h [12 mph])
for a few minutes may contribute to this
adaptation process ››› in Introduction on
page 283.

Practical tips
Diesel  V
alid for: vehicles with diesel engines
Pl ease note the information on the inside of
the fuel tank flap.
We recommend you use Diesel according to
standard EN 590.
The diesel can thicken at very low tempera-
tures, thus affecting the start or operation of
the engine. Ask your service station attendant
if their diesel is suitable for winter use.
Water in the fuel filter 1)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sep-
arator, the instrument panel may display the
following warning:

Checking and refilling levels

ake fluidFig. 229
Engine compartment: brake fluid res-
erv oir cap

. The brake fluid reservoir is located in the en-
gine compartment

› page 331
.
Checking the brake fluid level
The brake fluid level must be between the 
and  markings.
However, if the brake fluid level goes down
noticeably in a short time, or drops below the mark, there may be a leak in the brake system. Seek specialist assistance. A warning
light on the instrument panel display monitors
the brake fluid level ››› page 89
.
In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment. Changing brake fluid
We r

ecommend that you have the brake fluid
changed by a Technical Service. WARNING
If the brake fluid level is low or unsuita-
bl e/ol

d brake fluid is used, the brake sys-
tem may fail or braking power may be re-
duced.
