If large parts of the cyclist's body or bicycle are not visible to the function's camera thenthe system cannot detect a cyclist.
The function can only "see" cyclists from behind, who are travelling in the same direction.
• For the function to be able to detect a cyclist, he/she must be an adult and rid-ing a "senior bicycle".
• The bicycle must be equipped with a highly visible and approved 17
rearward-
facing red reflector, fitted at least 70 cm above the roadway.
• The function can only detect cyclistsdirectly from behind and who are travel-ling in the same direction - not at anangle from behind, not from the side.
• Cyclists travelling on the left or right-handedge of the car's imagined/extended sidelines may be detected late or not at all. •
The function's capacity to detect cyclistsat dusk and dawn is limited - just like thehuman eye.
• The function's capacity to detect cyclistsis deactivated when driving in darknessand tunnels - even when streetlights arelit.
• For optimum bicycle detection, the CitySafety™ function must be activated, CitySafety™ (p. 205).
WARNING
Collision Warning with Auto Brake & Cyclist Detection is a means of assistance. The function cannot detect: •all cyclists in all situations and does not see partially obscured cyclists, forexample.
• cyclists in clothing that obscures thecontours of the body or who areapproaching from the side.
• bicycles that have no rearward-facingred reflector.
• bicycles loaded with large objects.
The driver is always responsible that the vehicle is driven properly and with a safetydistance adapted to the speed.

Collision warning system* - detection of pedestrians
"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.
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 informationas possible about the contours of the body -this implies the opportunity to identify thehead, arms, shoulders, legs, upper and lowerbody combined with a normal human patternof movement. If large parts of the body are not visible to thecamera then the system cannot detect apedestrian.
• In order for a pedestrian to be detected he/she must appear full-length and havea height of at least 80 cm.
• The system cannot detect a pedestriancarrying larger items.
• The camera sensor's ability to see pedes-trians at dusk and dawn is limited - justlike the human eye.
• The camera sensor's capacity to detectpedestrians is deactivated when driving indarkness and tunnels - even when street-lights are lit.
WARNING
Collision Warning with Auto Brake & Pedestrian Detection is an assistance tool. This function cannot detect all pedestrians in all situations and it cannot see e.g. parti-ally obscured pedestrians, people in cloth-ing that hides the contours of the body orpedestrians shorter than 80 cm.
• The driver is always responsible that the vehicle is driven properly and witha safety distance adapted to thespeed.

Collision warning system* - operation
"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. Settings for the collision warning system are made from MY CAR via the centre console
screen and menu system, see MY CAR (p.103).
Warning signals On and OffYou can select whether the collision warningsystem's acoustic and visual warning signalsshould be switched on or off. When starting the engine, the setting that was selected when the engine was switched off isobtained automatically.
NOTE
The Brake Support and Auto Brake func- tions are always enabled - they cannot bedeactivated.
Light and acoustic signalsBoth the light and acoustic signals can be deactivated after starting the engine. Thefunction can be activated/deactivated in themenu system MY CAR. For a description of
the menu system, see MY CAR (p. 103). The warning lamp (see (1) in the illustration (p.213)) is tested each time the engine is startedby briefly lighting the separate light points ofthe warning lamp if the visual and acousticwarning of the collision warning system isactivated.
Acoustic signalThe warning sound can be activated/deacti-vated separately in the menu system
MY
CAR . For a description of the menu system,
see MY CAR (p. 103).
Set warning distanceThe warning distance regulates the distanceat which the visual and acoustic warnings aredeployed. The warning distance is set in themenu system MY CAR. For a description of
the menu system, see MY CAR (p. 103). The warning distance determines the sys- tem's sensitivity. Warning distance
Long pro-
vides an earlier warning. First test with Longand if this setting produces too many warn- ings, which could be perceived as irritating incertain situations, then change to warning distance
Normal.
Only use warning distance
Short in excep-
tional cases, e.g. for dynamic driving.
NOTE
When the adaptive cruise control is in use the warning lamp and warning sound willbe used by the cruise control even if thecollision warning system is switched off. The collision warning system warns the driver in the event of a risk of a collision,but the function cannot shorten driverreaction time. In order for the collision warning system to be effective, always drive with DistanceWarning (p. 202) set at time interval 4–5.
NOTE
Even if the warning distance has been set to Long warnings could be perceived as
being late in certain situations, e.g. when there are large differences in speed or ifvehicles in front brake heavily.
WARNING
No automatic system can guarantee 100 % correct function in all situations.Therefore, never test Collision Warningwith Auto Brake by driving at people orvehicles - this may cause severe damageand injury and risk lives.
Checking settingsThe settings required can be controlled on the centre console display screen. Searchwith the menu system (p. 103) MY CAR.

Collision warning system* - general limitations
"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 has certain limitations - for example, it is not active until approx. 4 km/h.. The collision warning system's visual warning signal (see (1) in the illustration (p. 213)) maybe difficult to notice in the event of strongsunlight, reflections, when sunglasses arebeing worn or if the driver is not lookingstraight ahead. The warning sound shouldtherefore always be activated. On slippery road surfaces the braking dis- tance is extended, which may reduce thecapacity to avoid a collision. In such situa-tions the ABS and DSTC systems will providebest possible braking force with maintainedstability.

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

Keeping Aid functions will not have full func- tionality either. The following table presents possible causes for a message being shown along with theappropriate action.
CauseAction
The windscreen surface in front ofthe camera is dirtyor covered with iceor snow.Clean the wind- screen surface infront of the camerafrom dirt, ice andsnow.
Thick fog, heavy rain or snow meansthat the cameradoes not work suffi-ciently well.No action. At times the camera doesnot work duringheavy rain or snow-fall.
CauseAction
The windscreen surface in front ofthe camera hasbeen cleaned butthe messageremains.Wait. It may take several minutes forthe camera tomeasure the visibil-ity.
Dirt has appeared between the insideof the windscreenand the camera.Visit a workshop to have the wind-screen inside thecamera covercleaned - an author-ised Volvo work-shop is recom-mended.
