Pedestrians
The system cannot identify all pedestrians
The Collision Warning system can only iden- tify and detect a pedestrian who is standingupright. This person can be standing still,walking or running. This means that the system has to be able to identify a person's head, arms, shoulders,legs, the upper and lower parts of the bodyand a person's pattern of movement whenwalking or running. If parts of the body are not visible to the cam- era, the system cannot detect the pedestrian. The following conditions apply:
• In order to detect a pedestrian, the sys- tem must have a full view of the person'sentire body and the person must be atleast 32 in. (80 cm) tall.
• The system cannot detect a pedestriancarrying a large object.
• The camera's capacity to see a pedes-trian at dawn or dusk is limited, much asit is for the human eye.
• The camera's function is deactivated andwill not detect a pedestrian in darkness orin tunnels, even if there is street lighting inthe area.
WARNING
• Collision Warning with Full Auto-brake and Pedestrian Detection is designedto be a supplementary driving aid. It isnot, however, intended to replace thedriver's attention and judgement. Thedriver is always responsible for operat-ing the vehicle in a safe manner.
• The system cannot detect all pedes-trians in all situations, such as in dark-ness/at night and cannot detect parti-ally hidden pedestrians, people whoare less than approx. 32 in. (80 cm)tall, or people wearing clothing thatobscures the contours of their bodies.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, vehicles or road marker lines infront of the vehicle. This, in turn, means that Collision Warning with Full Auto-brake and Pedestrian Detec-tion, Lane Departure Warning, and DriverAlert Control will not have full functionality. The table lists possible causes for this mes- sage being displayed, and suitable actions.

Driver Alert System*

170* Option/accessory, for more information, see Introduction.
Introduction
The Driver Alert System is designed to help a driver who may be becoming fatigued or whois inadvertently leaving the lane. The Driver Alert System consists of two differ- ent functions that can be switched ontogether or separately.
• Driver Alert Control (DAC)
• Lane Departure Warning (LDW)
, see
page 173
When one or both of the functions has beenswitched on, it is in standby mode and is acti-vated when the vehicle exceeds a speed of40 mph (65 km/h). The function deactivates if the vehicle's speed goes under 37 mph (60 km/h). Both functions use a camera that is depend- ent on the road/lane being clearly marked bypainted lines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be asupplementary aid. It is not, however,intended to replace the driver’s attentionand judgement.
Driver Alert Control (DAC)– introduction
This function is intended to alert the driver if his/her driving becomes erratic, such as if thedriver is distracted or fatigued.
NOTE
The camera has certain limitations, see page 149.
A camera monitors the painted lines marking the lane in which the vehicle is traveling andcompares the direction of the road with thedriver’s movements of the steering wheel.The driver is alerted if the vehicle does notfollow the lane smoothly. DAC is designed to help detect a slowlychanging driving pattern. It is primarilyintended to be used on main roads and is notmeant for use in city traffic.
WARNING
•
DAC is not intended to extend the duration of driving. Always plan breaksat regular intervals to help remain alert.
• In certain cases, fatigue may not affectthe driver’s behavior. In situations ofthis type, no warning will be provided.Therefore, it is important to takebreaks at regular intervals, regardlessof whether or not DAC has given awarning.
LimitationsIn certain situations, DAC may provide warn- ings even if the driver’s driving pattern hasnot become erratic.
• if the driver is testing the LDW function
• in strong crosswinds
• on grooved road surfaces.

Driver support systemsDriver Alert and check the box. If the box
is not checked, the function is off.
FunctionDriver Alert is activated when the vehicle exceeds a speed of 40 mph (65 km/h) and willremain active as long as the speed is overapprox. 37 mph (60 km/h). If the vehicle is being driven errati-cally, the driver will be alerted by anaudible signal and the message
Driver Alert Time for a break is
displayed. The warning will be repeated after a short time if the driving pattern remains thesame.
Press the OK button to erase a message.
WARNING
• An alert should be taken seriously since it is sometimes difficult for adriver to realize that he/she is fatigued.
• In the event of a warning or if thedriver feels fatigued, stop as soon aspossible in a safe place and rest.

Lane Departure Warning (LDW)– introduction
This function is designed to help reduce the risk of accidents in situations where the vehi-cle leaves its lane and there is a risk of drivingoff the road or into the opposite lane. LDWconsists of a camera that monitors the lane’sside marker lines. The driver is alerted by anaudible signal if the vehicle crosses a sidemarker line or the road’s center dividing line.
Operation and function
LDW can be switched on or off by pressing the button on the center console. A light inthe button illuminates when the function ison. This is supplemented by graphic displaysin the instrument panel, for example:
LDW displayed in the instrument panel
• The LDW symbol has
white side marker
lines: the function is active and "sees" one or both of the road's side markerlines.
• The LDW symbol has
gray side marker
lines: the function is active but cannot"see" one or both of the road's sidemarker lines.
or
• The LDW symbol has
gray side marker
lines: the function is in standby modebecause the vehicle's speed is below40 mph (65 km/h).
• The LDW symbol has
no side marker
lines: – the function is deactivated.

WARNING
The driver will only be warned once for each time the wheels cross a marker line.No alarm will be given if a marker line isbetween the wheels.
Limitations
The camera used by LDW has the same limi- tations as the human eye. See page166 for
more information about the camera's limita-tions.
NOTE
No warning signal will be given in the cer-
tain situations, such as:
• If the turn signal is being used
• The driver’s foot is on the brake pedal 1
• The accelerator pedal is pressed quickly 1
• If the steering wheel is moved quickly 1
• In sharp turns that cause the vehicle’s body to sway
Settings

Warning.
There are two alternatives:
On at start-up: This selection switches LDW
on each time the engine is started. Otherwise, the system will be in the mode that it was inwhen the engine was switched off.
Increased sensitivity: This selection increa-
ses the function’s sensitivity. Warnings will be given at an earlier stage and fewer limitationsapply. When this setting is being used, thesystem only needs to monitor lane markerlines on one side of the vehicle to change sta- tus to
Lane Depart Warn Available.
1 When Increased sensitivity has been selected, a warning will be issued if a side marker line is crossed in this situation.
