Maintenance
Camera and radar sensor 1
In order to function properly, the camera and radar sensor must be kept clean. Dirt, ice,snow, etc., will reduce the function of thesecomponents. Remove ice and snow when necessary and wash these areas regularly with a suitable carwashing liquid.
Limitations
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead may makethe visual warning signal in the windshield dif-ficult to see. For this reason, always activatethe audible warning signal. Slippery driving conditions increase braking distance, which can reduce the system'scapacity to avoid a collision. In these condi-tions, the ABS and DSTC systems providethe best possible braking effect while helpingto maintain stability.
NOTE
The visual warning signal may be tempo- rarily disengaged in the event of high pas-senger compartment temperature due tostrong sunlight, etc. If this occurs, theaudible warning signal will be used, even ifit has been deactivated in the menu sys-tem.
WARNING
• In certain situations, the system can- not provide warnings or warnings maybe delayed if traffic conditions or otherexternal factors make it impossible forthe radar sensor or camera to detect apedestrian, a cyclist or a vehicleahead.
• Warnings may not be provided if thedistance to the vehicle ahead is short,or if movements of the steering wheel/brake pedal are great, such as duringactive driving.
• The sensor system has a limited rangefor pedestrians/cyclists and provideswarnings and braking effect mosteffectively at speeds up to 30 mph(50 km/h). For stationary or slow-mov-ing vehicles, the system functions bestif your vehicle’s speed is belowapproximately 45 mph (70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sen-sors as Adaptive Cruise Control. For more

information on the radar sensor and its limita- tions, see page 165.
NOTE
If warnings are given too frequently, the warning distance can be reduced (seepage 180). This causes the system to pro-vide later warnings, which decreases thetotal number of warnings provided.
WARNING
• The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the Pedestrianand Cyclist Detection with Full AutoBrake system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.
The camera’s limitationsThe camera is used by Pedestrian and Cyclist Detection with Full Auto Brake, Driver AlertControl (see page 188), and Lane DepartureWarning (see page 190).
NOTE
• To help protect the camera in very hot conditions, it may be temporarilyswitched off for approximately 15minutes after the engine has beenstarted.
• Keep the section of the windshield infront of the camera clean and free ofice, snow, or condensation.

WARNING
• The camera has the same limitations as the human eye. In other words, its“vision is impaired” by adverseweather conditions such as heavysnowfall, dense fog, etc. These condi-tions may reduce the function of sys-tems that depend on the camera orcause these systems to temporarilystop functioning.
• Never place any objects, decals, etc.,on the windshield in front of the cam-era. This could reduce or block thecamera’s function, and could causeone or more of the systems that utilizethe camera to stop functioning.
• Strong sunlight, reflections from theroad surface, ice or snow covering theroad, a dirty road surface, or unclearlane marker lines may drasticallyreduce the camera’s capacity todetect the side of a lane, a pedestrian,a cyclist or another vehicle.
Pedestrian detection
The system cannot identify all pedestrians
The Pedestrian and Cyclist Detection with Full Auto Brake system can only identify anddetect a pedestrian who is standing upright.This person can be standing still, walking orrunning. 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's entire 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
• Pedestrian and Cyclist Detection with Full Auto Brake is designed to be asupplementary driving aid. It is not,however, intended to replace the driv-er'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.

WARNING
Pedestrian and Cyclist Detection with Full Auto Brake is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is alwaysresponsible for operating the vehicle in asafe manner. The system cannot detect a bike/cyclist if: • He/she is wearing loose-fitting clothing that may obscure body contours
• The bike is approaching your vehiclefrom the side
• The bike is not equipped with a rear-facing red reflector
• The bike is carrying large objects
• Most of the cyclist's body or the bikeitself cannot be "seen" by the system'scameraFault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, cyclists, vehicles or road markerlines in front of the vehicle. This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, LaneDeparture Warning, and Driver Alert Controlwill not have full functionality. The table lists possible causes for this mes- sage being displayed, and suitable actions.
CauseAction
The surface of the windshield in front of the camera is dirty or covered with ice or snow.Clean or clear the section of the windshield in front of the camera.
Fog, heavy rain or snow is interfering with the function of the camera.No action possible. Heavy precipitation may affect the function of the camera.

188* 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 and consistsof two different functions that can beswitched on together or separately.
• Driver Alert Control (DAC)
• Lane Departure Warning (LDW)
, see
page 190
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)
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 165.
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 slowly changing driving pattern. It is primarily intended 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, see page 190
• in strong crosswinds
• on grooved road surfaces.
Operating DACSettings are made using menu system and the display in the center console. See page209 for more information on the menu sys-tem.

Lane Departure Warning (LDW)
The illustration is generic
This function is designed to help reduce the risk of accidents in situations where the vehi- cle unintentionally leaves its lane and there isa risk of driving off the road or into the oppo-site lane. LDW uses the camera located at thecenter, upper edge of the windshield to moni-tor the road's/lane’s side marker lines. If thevehicle crosses a side marker line or theroad’s center dividing line, the driver will bealerted by an audible signal.
WARNING
This feature is only intended to assist the driver and does not function in all driving,weather, traffic or road conditions. As the driver, you have full responsibility for operating the vehicle in a safe manner.
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 is
