key inside the vehicle in the area of the front
or rear seats, or on the centre console.
In vehicles with the Keyless Access

started with the key in the luggage compart-

steering column if the ignition is disabled.
Switching the ignition on/off
If you only want to switch on the ignition
(without starting the engine), briefly press the
start button once without pressing the brake
pedal or the clutch pedal ››› .

Automatic ignition disconnection
If the driver leaves the vehicle, taking the key
with them but leaving the ignition on, the igni-

the sensor surface on the door lever

Driving
The radar sensors are located on the left and
right of the bumper and ar e not visibl
e from
the outside ››› Fig. 175
. The sensors monitor
both the blind spot and traffic behind the ve-
hicle ››› Fig. 176
.
They support the following functions:

Driver assistance systems
ACC detects it and adapts the speed au-
t omatically, maint
aining a distance set by
the driver.
Does my vehicle have ACC?
Your vehicle has ACC if it has a configuration
menu in the infotainment system ››› page 90
and if it has the ACC function buttons on the
multifunction steering wheel ››› Fig. 185
.
Speed range
ACC regulates speeds between 30 km/h (20
mph) and 210 km/h (130 mph). 1)
If the vehicle is fitted with an automatic gear-
box, the ACC can bring the vehicle to a
standstill if a vehicle in front of it stops.
If your vehicle is fitted with a manual gearbox,
you must pay attention to speed and gear
changes. The ACC is deactivated if the
speed is too low (less than 30 km/h) of the
engine RPM is too low or high.
Driver intervention prompt ACC is subject to certain limitations in-
herent to the system. This means that
the driver will have to control the speed
and distance from other vehicles in cer-
tain situations. In this case, the instru-
 ment cluster display will tell you t
o in-
tervene by applying the brake, and an
audio warning will be played.
Radar sensors
The ACC uses the front radar technology.
Read its maintenance instructions and infor-
mation about its limitations ››› page 243
. WARNING
The ACC’s technology cannot overcome
the syst em's inher

ent limitations or change
the laws of physics. If used negligently or
involuntarily, it may cause serious acci-
dents and injuries. The system is not a re-
placement for driver awareness.

Travel Assist uses the same sensors as Adap-
tive Cruise Control (ACC) and Lane Assist.
Therefore, carefully read the information
about the ACC ››› page 254
and the Lane
Assist ››› page 262
and take into account the
limitations of the systems and the indications
given in the information.
Speed range
Travel Assist adjusts at speeds between ap-
prox. 30 km/h (approx. 20 mph) and approx.
210 km/h (approx. 130 mph); in the case of
the adaptive lane guidance function, be-
tween 0 km/h (0 mph) and approx. 250 km/h
(approx. 155 mph). This range may vary de-
pending on the market.
Driving with Travel Assist
Travel Assist automatically controls the ac-
celerator pedal, the brakes and the steering.
In addition, Travel Assist may, within its limita-
tions, decelerate the vehicle until it stops be-
hind another that stops and automatically
starts again.
You can override assisted adjustment at all
times. How to know if the vehicle is fitted with

Rear cross traffic alert (RCTA) Fig. 198
Schematic representation of the rear
cr oss tr
affic alert assistant: zone monitored
around the vehicle while leaving a parking
space. Park Assist uses the radar sensors on the rear
bumper
››

› page 244
to monitor the traffic
crossing behind the vehicle as it backs out of
a parallel parking space or as it is being man-
oeuvred, for example in very low visibility con-
ditions.
When the system detects a relevant vehicle
on the road that is approaching the rear of
the vehicle ››› Fig. 198
, an acoustic alarm
may sound if the relevance so requires it.
In addition to the acoustic alarm, the driver is
also informed by means of a visual signal on
infotainment system display. This signal is dis- played in the form of a red or yellow strip at
the back of the image of the vehicl

e on the in-
fotainment system screen. This strip displays
the side of the vehicle towards which traffic is
approaching in transverse direction 1)
.
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 works within the limits of the
system. The parking assistant function
should not tempt you into taking any risks.
The system is not a replacement for driver
awareness.

Braking and parking
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 system (ASR)
In the event of the wheels spinning, the ASR
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 312
.
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
traject
ory is much more precise.
XDS works in combination with the ESC and is
always active, even when ASR is switched off,
or when the ESC is in Sport mode or discon-
nected.
Multi-collision brake
The multi-collision brake consists of automat-
ic braking activated by the Airbag control
unit. It is activated when, in the event of an
accident, the Airbag control unit detects de-
celerations above the activation level, and
braking is managed by the ESC system.
In the event of an accident, the multi-collision
brake can help the driver by braking to avoid
the risk of skidding during the accident and
causing other collisions.
The following actions control automatic brak-
ing during the accident:

Help with parking and manoeuvring
in the actual system and in the use of ultra-
sonic sensors. The use of P
ark Assist shoul
d
never tempt you to take any risk that may
compromise safety. The system is not a re-
placement for driver awareness.
