Emergencies
Tyre repairs T MS (T
yre Mobility System)* The Anti-puncture kit* (Tyre Mobility System)
will r
eliably seal punct

ures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign
objects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure
about 10 minutes after starting the engine.
You should only use the tyre mobility set if the
vehicle is parked in a safe place, you are fa-
miliar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following

Driving
Steering Inf ormation r
elating to different ve-
hicle processes. Electro-mechanical power steering adapts
el
ectr

onically to the speed of the car, torque
and steering angle.
Even if the power steering fails or the engine
is stopped, it is possible to continue to rotate
the steering wheel as long as the key remains
in the ignition, but more force must be ap-
plied.
Progressive steering
Depending on the vehicle’s features, it may or
may not incorporate a progressive steering
system.
In city traffic you do not need to turn so much
on parking, manoeuvring or in very tight turns.
On the road or on the motorway, progressive
steering transmits, for example, in bends, a
sportier, more direct and noticeably more dy-
namic driving sensation. Control lamp v

Faulty steering.
Do not continue driving, stop the v

possible and in a safe manner.
Take the vehicle to a specialised workshop and have
the fault repaired as soon as possible. v

If the warning light does not come on again after re-
starting the engine and driving a short distance, it is
not necessary to check the steering.

OR: The st eering column does not unlock or lock.
T
urn off the ignition and turn it on again. Consider the
messages shown on the instrument panel display.
Do not continue driving if the steering column re-
mains locked after switching on the ignition. Seek
specialist assistance. The control lamp should light up for a few
seconds when the ignition is s
wit

ched on. It
should go out once the engine is started. WARNING
Never ignore the warning lamps or messag-
es.

Driver assistance systems

.
Automatic braking to reduce damages
If the rear cross traffic alert detects that
someone else on the road is approaching the
rear of the vehicle and the driver does not
step on the brake, the system will engage the
brakes automatically.
The parking system helps the driver by auto-
matically engaging the brakes to reduce any
damage. The automatic intervention on the
brakes takes place when driving in reverse at
approx. 1-12 km/h (1-7 mph). After detecting
that the vehicle is stationary, the system
keeps it that way for around 2 seconds.
After automatically braking to reduce dam-
age, the system will not be able to automati-
cally brake again for approximately 10 sec-
onds.
You can interrupt the automatic braking by
stepping hard on the accelerator pedal or
the brake pedal in order to regain control of
the vehicle. WARNING
The smart technology incorporated into
the r ear cr

oss traffic alert cannot over- come the limits imposed by the laws of
physics; it only w
orks within the limits of the
syst

em. The parking assistant function
should not tempt you into taking any risks.
The system is not a replacement for driver
awareness.

Braking and parking

menu in the
infotainment system.

Braking and parking
harder, as the braking distance increases due
t o the l
ack of assistance from the servo brake. WARNING
Any anomaly in the brake system can in-
cr ease the br

aking distance, with the re-
sulting risk of an accident.

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. »
