Driver assistance systems
Lane departure warning (Side As-
sist) The lane departure warning uses radar sen-
sors t
o monit
or the areas behind the vehicle
››› page 9. The system does this by measur-
ing the vehicle's distance from other vehicles
and its speed differential. The lane departure
warning will not work at speeds of less than
approx. 15 km/h (9 mph).
The lane width is not detected individually,
but is rather pre-configured in the system.
Thus if you are driving in wide lanes or in be-
tween two lanes, the indications may be in-
correct. Furthermore, the system can detect
vehicles driving in the lane next to you (if
there are any), and can also detect station-
ary objects such as dividers, and thus give an
incorrect indication.
Light indication
The control lamp provides an indication on
the corresponding side regarding the traffic
situation behind the vehicle, if it is deemed to
be critical. The control lamp of the left-hand
side ››› Fig. 188
indicates the traffic situation
to the rear left of the vehicle, and the control
lamp of the right-hand side ››› Fig. 189
, indi-
cates the traffic situation to the rear right of
the vehicle. Keep the warning lamps zone of the lane de-
part
ur

e warning free of objects, adhesives or
the likes that may interfere with your visibility.

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.

system itself, the rear and side environment of
the v ehicl
e using the rear sensors
››› page 242. It detects moving objects that
approach from behind, such as cars
››› Fig. 193.
If a critical situation is detected when the
door is opened, it will be alerted by an acous-
tic signal on the door speaker of the corre-
sponding side ››› Fig. 194
. Additionally, the
control lamp of the lane departure warning of
the corresponding door will flash. If the door
has already been opened and another road
user has been detected in a critical situation,
the control lamp of the lane departure warn-
ing on the corresponding side will light up
permanently.
The brightness of the door opening warning
indication cannot be adjusted.
When you want to access the vehicle for the
first time, with the doors closed and locked,
the function will be available 3 minutes after
the first opening of any of the doors. The
function will continue to be available as long
as the vehicle has the ignition connected and
is not moving.
After switching off the ignition, the function
will remain available for approximately 3 mi-
nutes. After that time, the control lamps will
light up indicating the deactivation of the
function. WARNING

The engine rotates “correctly”.
The Auto Hold function is automatically
