Collision Warning with Auto Brake & Pedestrian Protection*

* Option/accessory, for more information, see Introduction.175 Detection of pedestrians
Optimal examples of what the system regards as
pedestrians with clear body contours.
Optimal performance of the system requires
that the system function that detects pedes-
trians receives as unambiguous information as
possible about the contours of the body - this
implies the opportunity to identify the head,
arms, shoulders, legs, upper and lower body
combined with a normal human pattern of
movement.
If large parts of the body are not visible to the
camera then the system cannot detect a
pedestrian.
•In order for a pedestrian to be detected he/
she must appear full-length and have a
height of at least 80 cm.
•The system cannot detect a pedestrian
carrying larger items.
•The camera sensor's ability to see pedes-
trians at dusk and dawn is limited - just like
the human eye.
•The camera sensor's capacity to detect
pedestrians is deactivated when driving in
darkness and tunnels - even when street-
lights are lit.
WARNING
Collision Warning with Auto Brake & Pedes-
trian Detection is an assistance tool.
This function cannot detect all pedestrians
in all situations and it cannot see e.g. parti-
ally obscured pedestrians, people in cloth-
ing that hides the contours of the body or
pedestrians shorter than 80 cm.
•The driver is always responsible that the
vehicle is driven properly and with a
safety distance adapted to the speed.
Operation
Settings are made from MY CAR via the centre
console display screen and menu system. For
information on how the menu system is used,
see page 202.
NOTE
The Brake Support and Auto Brake func-
tions are always enabled - they cannot be
deactivated.
On and OffTo select whether the collision warning system
should be switched on or off:
•Use the menu system MY CAR via the
centre console display to search for

there, select
On or Off.
An activated function is tested every time the
engine is started by briefly illuminating the sep-
arate lights for the warning lamp (no. [1] in the
illustration on page 173).
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.

Driver Alert System*
04
* Option/accessory, for more information, see Introduction.181 General information on Driver Alert
System
The Driver Alert System is intended to assist
drivers whose driving ability is deteriorating or
who are inadvertently leaving the lane they are
driving on.
The Driver Alert System consists of different
functions which can either be switched on at
the same time or individually:
•Driver Alert Control – DAC, see page 182.
•Lane Departure Warning – LDW, see
page 185.
A switched-on function is set in standby mode
and is not activated automatically until speed
exceeds 65 km/h.
The function is deactivated again when speed
decreases to below 60 km/h.
Both functions use a camera which is depend-
ent on the lane having side markings painted
on each side.
WARNING
The Driver Alert System does not work in all
situations but is instead only intended to be
of supplementary assistance.
The driver always has ultimate responsibility
that the car is driven safely.

Driver Alert System - DAC*
04
182* Option/accessory, for more information, see Introduction.
General information on DAC
The DAC (Driver Alert Control) function is
intended to attract the driver's attention when
he/she starts to drive less consistently, e.g. if
he/she becomes distracted or starts to fall
asleep.
A camera detects the side markings painted on
the carriageway and compares the section of
the road with the driver's steering wheel move-
ments. The driver is alerted if the vehicle does
not follow the carriageway evenly.
NOTE
The camera sensor has certain limitations,
see page 178.
The objective for DAC is to detect slowly dete-
riorating driving ability and it is primarily
intended for major roads. The function is not
intended for city traffic.
In some cases driving ability is not affected
despite driver fatigue. In which case there may
not be any warning issued for the driver. For
this reason it is always important to stop and
take a break in the event of any signs of driver
fatigue, irrespective of whether or not DAC
issues a warning.
NOTE
The function must not be used to extend a
driving stint. Always plan breaks at regular
intervals and ensure that you are fully
rested.
LimitationIn some cases the system may issue a warning
despite driving ability not deteriorating, for
example:
•if the driver tests the LDW function.
•in strong side winds.
•on rutted road surfaces.
Operation
Some settings are made from the centre con-
sole display screen and its menu system. For
information on how the menu system is used,
see page 202.
The current status of Driver Alert can be
checked on the trip computer display with the
thumbwheel on the left-hand stalk switch.

systems
Driver Alert and tick the box.
•No tick in the box: Function disengaged.
FunctionDriver Alert is activated when speed
exceeds 65 km/h and remains active
as long as the speed is over
60 km/h.
The display shows a level mark with 1-5 bars,
where a low number of bars indicates incon-
sistent driving style. Many bars indicates stable
driving.
If the vehicle is driven inconsistently then the
driver is alerted by an acoustic signal as well as
the text message
Driver Alert Time for a
break. The warning is repeated after a time if
driving ability does not improve.
WARNING
An alarm should be taken very seriously, as
a sleepy driver is often not aware of his/her
own condition.
In the event of an alarm or a feeling of tired-
ness; stop the car in a safe manner as soon
as possible and rest.
Studies have shown that it is equally as dan-
gerous to drive while tired as it is under the
influence of alcohol.
