NOTE
The visual warning signal can be temporar- ily disengaged in the event of high passen-ger compartment temperature caused bystrong sunlight for example. If this occursthen the warning sound is activated even ifit is deactivated in the menu system.
• Warnings may not appear if the dis- tance to the vehicle in front is small orif steering wheel and pedal move-ments are large, e.g. a very active driv-ing style.
WARNING
Warnings and brake interventions could be implemented late or not at all if the trafficsituation or external influences mean thatthe radar or camera sensor cannot detecta pedestrian, a vehicle or a cyclist in frontcorrectly. The sensor system has a limited range for pedestrians and cyclists 19
- the system
can provide effective warnings and brake interventions for them at vehicle speeds upto 50 km/h. For stationary or slow-movingvehicles, warnings and brake interventionsare effective at vehicle speeds up to70 km/h. Warnings for stationary or slow-moving vehicles could be disengaged due to dark-ness or poor visibility. Warnings and brake interventions for pedestrians and cyclists are deactivated atvehicle speeds exceeding 80 km/h.
The collision warning system uses the same radar sensors as the Adaptive cruise control(p. 188). Read more about radar sensor limi-tations (p. 197). If warnings are perceived as being too fre- quent or disturbing then the warning distancecan be reduced (p. 217). This would lead tothe system warning at a later stage, whichreduces the total number of warnings. Collision Warning with Auto Brake is tempo-rarily deactivated with reverse gear engaged. Collision Warning with Auto Brake is not acti- vated at low speeds - under 4 km/h, which iswhy the system does not intervene in situa-tions where the car is approaching a vehiclein front very slowly, e.g. when parking. In situations where the driver demonstrates active, aware driving behaviour, a collisionwarning may be postponed slightly in order tokeep unnecessary warnings to a minimum. When Auto Brake has prevented a collision with a stationary object the car remains sta-tionary for a maximum of 1.5 seconds. If thecar is braked for a vehicle in front that is mov-ing, then speed is reduced to the same speedas that maintained by the vehicle in front. On a car with manual gearbox the engine stops when Auto Brake has stopped the car,unless the driver manages to depress theclutch pedal beforehand.

"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

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.

Settings are made from the centre console display screen and its menu system. For infor-mation on how the menu system is used, seeMY CAR (p. 103). Depending on whether the car has Lane Departure Warning - LDW (p. 229) or LaneKeeping Aid - LKA (p. 234) the screen canshow one of the following options:
Car with LDW can show this on the screen.
Car with LKA can show this on the screen.
The Driver Alert function can be set in standby mode. The function can be acti-vated/deactivated in the menu system MY
CAR . For a description of the menu system,
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

Lane Keeping Aid (LKA) - limitations
The Lane Keeping Aid camera sensor is restricted in a similar way to the human eye.
• For more information, read about camera sensor limitations (p. 220) and seeColli-sion warning system* - operation (p. 217).
NOTE
In certain demanding situations LKA may find it difficult to assist the driver correctly- in which case it is recommended thatLKA is switched off. Examples of such a situation could be:
• roadworks
• winter road conditions
• poor road surface
• very sporty driving style
• poor weather with reduced visibility.
Hands on the steering wheelIn order for Lane Keeping Aid to operate, the driver must have his/her hands on the steer-ing wheel. LKA continually monitors this. Ifhands are not detected on the steering wheelthen a text message is shown, prompting thedriver to actively steer the car. If the driver does not follow the request to begin steering, Lane Keeping Aid goes intostandby mode and will remain in this modeuntil the driver begins to steer the car again.
