"Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is an aid toassist the driver when there is a risk of collid-ing with a pedestrian, bicycle or vehicle infront that are stationary or moving in the samedirection.
The function uses the car's camera sensor,
which has certain limitations. The car’s camera sensor is also used - as well as by Collision Warning with Auto Brake- by the functions:
• Automatic main/dipped beam dim- ming (p. 82)
• Road sign information (p. 179)
• Driver Alert Control - DAC (p. 224)
• Lane Keeping Aid (p. 229)
NOTE
Keep the windscreen surface in front of the camera sensor free from ice, snow, mistand dirt. Do not stick or attach anything to the windscreen in front of the camera sensoras this may reduce effectiveness or causeone or more of the systems dependent onthe camera to stop working.
The camera sensors have limitations similar to the human eye, i.e. they "see" worse in darkness, heavy snowfall or rain and in thickfog for example. Under such conditions thefunctions of camera-dependent systemscould be significantly reduced or temporarilydisengaged. Strong oncoming light, reflections in the car- riageway, snow or ice on the road surface,dirty road surfaces or unclear lane markingscould also significantly reduce camera sensorfunction when it is used to scan the carriage-way and detect pedestrians and other vehi-cles. The field of vision of the camera sensor is lim- ited, which is why pedestrians, cyclists andvehicles cannot be detected in some situa-tions, or they are detected later than anticipa-ted. During very high temperatures the camera is temporarily switched off for about 15 minutesafter the engine is started in order to protectcamera functionality.
Fault tracing and actionIf the display shows the messageWindscreen Sensors blocked then this
means that the camera sensor is blocked and cannot detect pedestrians, cyclists, vehiclesor road markings in front of the car. At the same time, this means that - besides Collision Warning with Auto Brake - the Auto-matic main/dipped beam dimming, Road SignInformation, Driver Alert Control and Lane

driver fatigue, irrespective of whether or not DAC issues a warning.
NOTE
The function must not be used to extend a period of driving. Always plan breaks atregular intervals, and make sure you arewell rested.
LimitationIn some cases the system may issue a warn- ing despite driving ability not deteriorating, forexample: •
in strong side winds
• on rutted road surfaces.
NOTE
The camera sensor has certain limitations (p. 220).

see MY CAR (p. 103). Driver Alert is activated when speed exceeds 65 km/h and remains active as long as thespeed is over 60 km/h.
If the vehicle is being driven errati-cally, the driver is notified by anacoustic signal plus the text mes- sage

Park Assist*
Parking assistance is used as an aid to park- ing. An acoustic signal as well as symbols onthe centre console's display screen indicatethe distance to the detected obstacle. Parking assistance sound level can be adjusted during the ongoing acoustic signalusing the centre console's VOL knob. The
sound level can also be adjusted in the audiosettings menu, which is accessed by pressingSOUND or in the car's menu system (p. 103)

.
Parking assistance is available in two vari-ants:
• Rear only
• Both front and rear.
NOTE
When a towbar is configured with the car's electrical system, the protrusion of thetowbar is included when the functionmeasures the parking space.
WARNING
•Parking assistance does not relinquish the driver's own responsibility duringparking.
• The sensors have blind spots whereobstacles cannot be detected.
• Be aware of e.g. people or animalsnear the car.

Display screen view - showing an obstacle left front and right rear. The centre console's display screen shows an overview of the relationship between thecar and detected obstacle. Marked sectors show which of the four sen- sor(s) detected an obstacle. The closer to thecar symbol a selected sector box is, theshorter the distance between the car and adetected obstacle. The frequency of the signal increases the shorter the distance to an obstacle, in front ofor behind the car. Other sound from the audiosystem is muted automatically. When the distance is within 30 cm the tone is constant and the active sensor's field nearestthe car is filled in. If the detected obstacle iswithin the distance for the constant tone bothbehind and in front of the car, then the tonesounds alternately from the loudspeakers.
IMPORTANT
Objects e.g. chains, thin glossy poles or low barriers may be in the "signal shadow"and are then temporarily not detected bythe sensors - the pulsating tone may thenunexpectedly stop instead of changingover to the expected constant tone. The sensors cannot detect high objects, such as projecting loading docks.
• In such situations, pay extra attention and manoeuvre/reposition the car par-ticularly slowly or stop the currentparking manoeuvre - there may be ahigh risk of damage to vehicles orother objects since the sensors aretemporarily unable to function opti-mally.

The distance covered to the rear of the car is about 1.5 metres. The acoustic signal forobstacles behind comes from one of the rearloudspeakers. Rear parking assistance is activated when reverse gear is engaged. When reversing with e.g. a trailer on the tow- bar, rear parking assistance is switched offautomatically - otherwise the sensors wouldreact to the trailer.

The parking assistance system is automati- cally activated when the engine is started -the switch's On/Off lamp is illuminated. Ifparking assistance is switched off with thebutton, the lamp goes out.
The distance covered in front of the car is about 0.8 metres. The acoustic signal forobstacles in front comes from one of the frontloudspeakers. Front park assist is active up to approx. 10 km/h. The lamp in the button isilluminated in order to indicate that the sys-tem is activated. When the speed is below10 km/h the system is reactivated.
NOTE
Front parking assistance is deactivated when the parking brake is applied or

mode is selected in a car with an auto-matic gearbox.
IMPORTANT
When auxiliary lamps are fitted: Remember that these must not obscure the sensors -the auxiliary lamps may then be perceivedas an obstacle.

IMPORTANT
In certain conditions the parking assis- tance system may produce incorrect warn-ing signals that are caused by externalsound sources that emit the same ultra-sonic frequencies that the system workswith. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakesand exhaust noises from motorcycles etc.

Park assist camera
The parking camera is an assist system and is activated when reverse gear is engaged (canbe changed in the settings menu (p. 246)). The camera image is shown on the centre console's screen.
NOTE
When a towbar is configured with the car's electrical system, the protrusion of thetowbar is included when the functionmeasures the parking space.
WARNING
• The parking camera serves as an aid. It does not relieve the driver of respon-sibility when reversing.
• The camera has blind spots, whereobstacles cannot be detected.
• Be aware of people and animals in thevicinity of the car.
Function and operation
CAM
button location.
The camera shows what is behind the car and if something appears from the sides. The camera shows a wide area behind the car and part of the bumper and any towbar. Objects on the screen may appear to tilt slightly - this is normal.
NOTE
Objects on the display screen may be closer to the car than they appear to be onthe screen.
If another view is active the parking camera system takes over automatically and thecamera image is displayed on the screen. When reverse gear is engaged two unbroken lines are shown graphically which illustrate where the car's rear wheels will roll with thecurrent steering wheel angle, this facilitatestight parking, reversing into tight spaces andfor hitching a trailer. The car’s approximateexternal dimensions are illustrated by meansof two dashed lines. These park assist linescan be switched off in the settings menu. If the car is also equipped with parking assis- tance sensors* then their information is dis-played graphically as coloured fields in orderto illustrate the distance to detected obsta-cles, see the heading "Cars with reversingsensors" later in the text. The camera is active approx. 5 seconds after reverse gear has been disengaged or until thecar's speed exceeds 10 km/h forward or35 km/h backward.
