Collision Warning with Auto Brake & Pedestrian Protection*

196* Option/accessory, for more information, see Introduction.
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 a means of assistance.
It cannot detect all pedestrians in all situa-
tions and it cannot see e.g. partially
obscured pedestrians, people in clothing
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.
Fault tracing and action
If the display shows the message Windscreen
Sensors blocked then this means that the
camera sensor is blocked and cannot detect
pedestrians, vehicles or road markings in front
of the car.In turn this means that the Collision Warning
with Auto Brake, Lane Departure Warning and
Driver Alert Control functions are not operating
with full functionality.
The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The windscreen sur-
face in front of the
camera is dirty or
covered with ice or
snow.Clean the wind-
screen surface in
front of the camera
from dirt, ice and
snow.
Thick fog, heavy rain
or snow means that
the camera does not
work sufficiently
well.No action. At times
the camera does not
work during heavy
rain or snowfall.

Driver Alert System – DAC*
04
* Option/accessory, for more information, see Introduction.199 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 two differ-
ent functions, which can either be switched on
at the same time or individually:
•Driver Alert Control (DAC)
•Lane Departure Warning (LDW), see
page 202.
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.
General information on Driver Alert
Control - DAC
The function is intended to attract the driver's
attention when he/she starts to drive less con-
sistently, 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 195.
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.

The number of bars can vary in the range 1-5, where a low number of bars indicates inconsistent
driving ability. A high number of bars indicates stable driving.

Driver Alert System - LDW*
04
202* Option/accessory, for more information, see Introduction.
General information on Lane Departure
Warning - LDW
The function is intended to reduce the risk for
single-vehicle accidents – accidents where, in
certain situations, the vehicle leaves the car-
riageway and is in danger of driving either into
a ditch or into oncoming traffic.
LDW consists of a camera that detects the side
markings painted on the carriageway. The
driver is alerted by an acoustic signal if the
vehicle crosses a side marking.
Operation and function
The function is switched on or off by means of
a switch on the centre console. An indicator
lamp in the button illuminates when the func-
tion is switched on.
The trip computer display shows
Lane Depart
Warn Standby <65 km/h when the function is
in standby mode due to speed being below 65
km/h.
The LDW function is activated automatically
from standby mode after the camera has scan-
ned in the carriageway's side markings and
speed exceeds 65 km/h. The trip computer
display then shows
Lane Depart Warn
Available.If the camera can no longer detect the carria-
geway's side markings the display shows
Lane Depart Warn Unavailable.
If speed decreases to below 60 km/h then the
function resumes standby mode and the dis-
play shows
Lane Depart Warn Standby <65
km/h.
If the vehicle crosses the left or right-hand side
marking of the carriageway without due cause
then the driver is alerted by an acoustic signal.
No warning is given in the following situations:
•Direction indicators activated
•The driver has his/her foot on the brake
pedal1
•In the event of the accelerator pedal being
depressed rapidly1
•In the event of rapid steering wheel move-
ments1
•In the event of a sudden turn so that the car
rolls.
The camera sensor also has certain limitations.
For more information, see page 195.

Park assist syst*
04
* Option/accessory, for more information, see Introduction.205 General
Parking assistance is used as an aid to parking.
An acoustic signal as well as symbols on the
centre console's display screen indicate the
distance to the detected obstacle.
Parking assistance sound level can be
adjusted during the ongoing acoustic signal
using the centre console's VOL knob or in the
car's menu system MY CAR - see page 144.
Parking assistance is available in two variants:
•Rear only
•Both front and rear.
WARNING
•Parking assistance does not relinquish
the driver's own responsibility during
parking.
•The sensors have blind spots where
obstacles cannot be detected.
•Be aware of e.g. people or animals near
the car.
Function
The system is automatically activated when the
engine is started - the switch's On/Off lamp is
illuminated. If parking assistance is switched
off with the button, the lamp goes out.
Display screen view - showing an obstacle left
front and right rear.
The centre console's display screen shows an
overview of the relationship between the car
and detected obstacle.
Marked sectors show which of the four sen-
sor(s) detected an obstacle. The closer to the
car symbol a selected sector box is, the shorter
the distance between the car and a detected
obstacle.
The frequency of the signal increases the
shorter the distance to an obstacle, in front of
or behind the car. Other sound from the audio
system is muted automatically.
When the distance is within 30 cm the tone is
constant and the active sensor's field nearest
the car is filled in. If the detected obstacle is
within the distance for the constant tone both
