Radar sensor The function of the radar sensor is to detect cars or larger vehicles in the same direction, in the same lane.

The radar sensor is used by the following functions: • Distance Warning* • Adaptive cruise control* • Collision Warning System with Auto

Brake and Cyclist and Pedestrian Detec- tion*

IMPORTANT

In the event of visible damage to the car's grille, or if you suspect that the radar sen- sor may be damaged: • Contact a workshop - an authorised

Volvo workshop is recommended.

The function may completely or partially disappear - or malfunction - if the grille, the radar sensor or its bracket is damaged or has loosened.

Modification of the radar sensor could result in it being illegal to use.

07 Driver support

Radar sensor - limitations A radar sensor (p. 213) has certain limitations - due to its limited field of vision for example.

The capacity of the adaptive cruise control to detect a vehicle in front is significantly reduced if: • the speed of vehicles in front is signifi- cantly different from your own speed

• its radar sensor becomes blocked - e.g. in heavy rain or slush, or if other objects have collected in front of the radar sen- sor.

NOTE

Keep the area in front of the radar sensor clean - see subheading "Maintenance" (p. 233).

Field of vision The radar sensor has a limited field of vision. In some situations another vehicle is not detected, or the detection is made later than expected.

07

214

ACC field of vision.

Sometimes the radar sensor is late at detecting vehicles at close distances - e.g. a vehicle that drives in between the car and vehicles in front. Small vehicles, such as motorcycles, or vehicles not driving in the centre of the lane can remain undetected. In bends the radar sensor may detect the wrong vehicle or lose a detected vehicle from view.

WARNING

The driver must always be observant with regard to the traffic conditions and inter- vene when the adaptive cruise control is not maintaining a suitable speed or suita- ble distance. The adaptive cruise control cannot handle all traffic, weather and road conditions. Read all the sections about the adaptive cruise control in the owner's manual in order to learn about its limitations, of which the driver should be aware before it is used. The driver always bears responsibility for maintaining the correct distance and speed, even when the adaptive cruise con- trol is being used.

WARNING

Accessories or other objects such as auxil- iary lamps must not be fitted in front of the grille.

WARNING

Adaptive cruise control is not a collision avoidance system. The driver must inter- vene if the system does not detect a vehi- cle in front. The adaptive cruise control does not brake for humans or animals, and not for small vehicles such as bicycles and motorcy- cles. Nor for oncoming, slow or stationary vehicles and objects. Do not use the adaptive cruise control, for example, in city traffic, in dense traffic, at junctions, on slippery surfaces, with a lot of water or slush on the road, in heavy rain/snow, in poor visibility, on winding roads or on slip roads.

Adaptive cruise control* - fault tracing and action

If the combined instrument panel shows the message Radar blocked See manual then it means that the adaptive cruise control's radar

sensor (p. 213) cannot detect other vehicles in front of the car. This message indicates that neither of the functions for Distance Alert (p. 219) or Colli-

sion Warning with Auto Brake (p. 229) are working. The following table presents examples of possible causes for a message being shown along with the appropriate action:

Cause

Action

The radar surface in the grille is dirty or covered with ice or snow. Clean the radar surface in the grille from dirt, ice and snow.

Heavy rain or snow blocking the radar signals.

No action. Sometimes the radar does not work during heavy rain or snowfall.

Water or snow from the road surface swirls up and blocks the radar signals.

No action. Sometimes the radar does not work on a very wet or snowy road surface.

The radar surface has been cleaned but the message remains.

Wait. It could take several minutes for the radar to sense that it is no longer blocked.

are some examples - follow the recommenda- tion given if appropriate:

Symbol Message

Specification

The symbol is GREEN

The car maintains the stored speed.

The symbol is WHITE

Adaptive cruise control is set to standby mode.

Standard cruise control is selected manually.

Set ESC to Normal to enable Cruise

The adaptive cruise control cannot be activated until the Stability system (ESC) (p. 191) has been set in Normal mode.

Adaptive cruise control cancelled

Adaptive cruise control unavailable

Radar blocked See man- ual

The adaptive cruise control has been deactivated - the driver has to regulate the speed himself.

The adaptive cruise control cannot be activated. This could be due to: • brake temperature is high • the radar sensor is blocked by e.g. wet snow or rain. The adaptive cruise control is temporarily disengaged. • The radar sensor is blocked and cannot detect other vehicles. For example, in the event of heavy

rain or if slush has collected in front of the radar sensor.

The driver can then choose to switch to (p. 213) normal Cruise control (CC) - a text message provides information on appropriate alternatives. Read about radar sensor limitations (p. 214).

Distance Warning* The Distance Warning function (Distance Alert) warns the driver if the time interval to the vehicle ahead becomes too short.

Distance Warning is active at speeds above 30 km/h and only reacts to vehicles driving in front of the car, in the same direction. No dis- tance information is provided for oncoming, slow or stationary vehicles.

NOTE

Distance warning is deactivated during the time the adaptive cruise control is active.

WARNING

Distance warning only reacts if the dis- tance to the vehicle ahead is shorter than the preset value - the speed of the driver's vehicle is not affected.

Operation

Distance Warning* - limitations

This function, which uses the same radar sensor as Adaptive cruise control (p. 204) and Collision warning with auto brake (p. 229), has certain limitations.

NOTE

Strong sunlight, reflections or strong varia- tions in light intensity, as well as wearing sunglasses, could mean that the warning light in the windscreen cannot be seen. Poor weather or winding roads could affect the radar sensor's capacity to detect vehicles in front. The size of other vehicles could also affect detection capacity, e.g. motorcycles. This could mean that the warning lamp illumi- nates at a shorter distance than the setting or that the warning is temporarily absent. Extremely high speeds can also cause the lamp to illuminate at a shorter distance than that set due to limitations in sensor range.

For further information on radar sensor limita- tions, see Radar sensor - limitations (p. 214) and (p. 234).

City Safety™ - function City Safety detects the traffic in front of the car with a laser sensor fitted in the top edge of the windscreen. If there is an imminent risk of collision, City Safety will automatically brake the car, which may be experienced as heavy braking.

07 Driver support

City Safety™ City Safety™ is a function for helping the driver to avoid a collision when driving in queues, amongst other things, when changes in the traffic ahead, combined with a lapse in attention, could lead to an incident.

The City Safety™ function is active at speeds under 50 km/h and it helps the driver by auto- matically braking the car in the event of immi- nent risk of collision with vehicles in front, should the driver not react in time by braking and/or steering away. City Safety™ is activated in situations where the driver should have started braking earlier, which is why it cannot help the driver in every situation. City Safety™ is designed to be activated as late as possible in order to avoid unnecessary intervention. City Safety™ must not be used as an excuse for the driver to change his/her driving style. If the driver solely relies on City Safety™ to do the braking, there will be a collision sooner or later. The driver or passengers normally only notice City Safety™ if a situation arises where the car is extremely close to being in a collision. If the car is also equipped with Collision Warning with Auto Brake (p. 229)* these two systems complement each other.

07

IMPORTANT

Maintenance and replacement of City Safety™ components must only be per- formed by a workshop - an authorised Volvo workshop is recommended.

WARNING

City Safety™ does not engage in all driv- ing situations or traffic, weather or road conditions. City Safety™ does not react to vehicles driving in a different direction from the car, to small vehicles and motorcycles or to humans and animals. City Safety™ can prevent collision at a speed difference of less than 15 km/h - at a higher speed difference, it is only possi- ble to reduce collision speed. In order to obtain full brake function, the driver must depress the brake pedal. Never wait for City Safety™ to engage. The driver always bears responsibility for maintaining the proper distance and speed.

Laser sensor transmitter and receiver window14. If the speed difference is 4-15 km/h in relation to the vehicle in front then City Safety can completely avoid a collision. City Safety activates a short, sharp braking procedure and stops the car in normal cir- cumstances, just behind the vehicle in front. For most drivers this is well outside normal driving style and may be experienced as being uncomfortable. If the difference in speed between the vehi- cles is greater than 15 km/h then City Safety may not avoid the collision on its own - to obtain full brake force, the driver must depress the brake pedal and this could then make it possible to avoid a collision, even at speed differences above 15 km/h.

15 (Anti-lock Braking System) - Anti-lock braking system. 16 (Electronic Stability Control) - Stability system.

When your own car is reversing, City Safety is temporarily deactivated. City Safety is not activated at low speeds - under 4 km/h, which is why the system does not intervene in situations where a vehicle in front is being approached very slowly, e.g. when parking. Driver commands are always prioritised, which is why City Safety does not intervene in situations where the driver is steering or accelerating in a clear manner, even if a colli- sion is unavoidable. When City Safety has prevented a collision with a stationary object the car remains sta- tionary for a maximum of 1.5 seconds. If the car is braked for a vehicle in front that is mov- ing, then speed is reduced to the same speed as that maintained by the vehicle in front. On a car with manual gearbox the engine stops when City Safety has stopped the car, unless the driver manages to depress the clutch pedal beforehand.

City Safety™ - limitations The sensor in City Safety is designed to detect cars and other large vehicles in front of the car irrespective of whether it is day or night. However, the function does have some limita- tions.

The sensor's limitations mean that City Safety has poorer functionality - or none at all - in e.g. heavy snowfall or rain, dense fog, dust storms or white-out situations. Misting, dirt, ice or snow on the windscreen may also dis- rupt the function. Low-hanging objects, e.g. a flag/pennant for projecting load, or accessories such as auxili- ary lamps and bull bars that are higher than the bonnet limit the function. The laser beam from the sensor in City Safety measures how the light is reflected. The sen- sor cannot detect objects with low reflection capacity. The rear sections of the vehicle generally reflect the light sufficiently thanks to the number plate and rear light reflectors. On slippery road surfaces the braking dis- tance is extended, which may reduce the capacity of City Safety to avoid a collision. In such situations the ABS15 and ESC16 systems will provide best possible braking force with maintained stability.

NOTE

IMPORTANT

07 Driver support

The windscreen sur- face in front of the laser sensor is dirty or covered with ice or snow.

Clean the wind- screen surface in front of the sensor from dirt, ice and snow.

The laser sensor field of vision is blocked.

Remove the blocking object.

• Keep the windscreen surface in front of the laser sensor free from ice, snow and dirt (see the illustration for sensor location (p. 222)).

• Do not affix or mount anything on the windscreen in front of the laser sensor. • Remove ice and snow from the bonnet

- snow and ice must not exceed a height of 5 cm.

Fault tracing and action If the message Windscreen sensors blocked See manual is shown in the com- bined instrument panel it indicates that the laser sensor is blocked and cannot detect vehicles in front of the car. This means in turn that City Safety is not operational. The Windscreen sensors blocked See manual message is not shown for all situa- tions in which the laser sensor is blocked. The driver must therefore be diligent about keeping the windscreen and area in front of the laser sensor clean. The following table presents possible causes for the message being shown, along with suggestions for appropriate action.

If there are cracks, scratches or stone chips in the windscreen in front of either of the laser sensor's "windows" and they cover a surface of approx. 0.5 x 3.0 mm (or larger), then a workshop must be con- tacted for replacement of the windscreen (see the illustration for sensor location (p. 222)) - an authorised Volvo workshop is recommended. Failure to take action may result in reduced performance for City Safety™. To avoid the risk of failed, deficient or reduced operation for City Safety™, the following also applies: • Volvo recommends that you do not

repair cracks, scratches or stone chips in the area in front of the laser sensor - instead, the whole windscreen should be replaced.

• Before replacing a windscreen, con- tact an authorised Volvo workshop to verify that the correct windscreen is ordered and fitted.

• The same type or Volvo-approved

windscreen wipers must be fitted dur- ing replacement.

City Safety™ - laser sensor The City Safety™ function includes a sensor which transmits laser light (see illustration (p. 222) for sensor location). Contact a quali- fied workshop in the event of a fault or if the laser sensor needs servicing - an authorised Volvo workshop is recommended. It is abso- lutely essential to follow the prescribed instructions when handling the laser sensor.

The following two labels relate to the laser sensor:

• IEC 60825-1:1993 + A2:2001. Complies

with FDA (U.S. Food Administration) standards for laser product design with the exception of deviations in accordance with "Laser Notice No. 50" from 26 July 2001.

WARNING

If any of these instructions are not followed then there is a risk of eye injury! • Never look into the laser sensor (which

emits spreading invisible laser radia- tion) at a distance of 100 mm or closer with magnifying optics such as a mag- nifying glass, microscope, lens or simi- lar optical instruments.

• Testing, repair, removal, adjustment and/or replacement of the laser sen- sor's spare parts must only be carried out by a qualified workshop - we rec- ommend an authorised Volvo work- shop.

• To avoid exposure to harmful radia- tion, do not carry out any readjust- ments or maintenance other than those specified here.

• The repairer must follow specially

drawn up workshop information for the laser sensor.

• Do not remove the laser sensor (this

includes removing the lenses). A removed laser sensor does not fulfil laser class 3B as per standard IEC 60825-1. Laser class 3B is not eye- safe and therefore entails a risk of injury.

• The laser sensor's connector must be

unplugged before removal from the windscreen.

• The laser sensor must be fitted onto the windscreen before the sensor's connector is plugged in.

• The laser sensor transmits a laser light when the remote control key is in key position II (p. 81) even if the engine is switched off.

Collision warning system* "Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is an aid to assist the driver when there is a risk of collid- ing with a pedestrian, cyclist or vehicle in front that are stationary or moving in the same direction.

"Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is activated in situations where the driver should have started braking earlier, which is why it cannot help the driver in every situation. "Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is designed to be activated as late as possible in order to avoid unnecessary intervention. "Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" can pre- vent a collision or reduce collision speed. "Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" must not be used as an excuse for the driver to change his/her driving style. If the driver solely relies on Collision Warning with Auto Brake to do the braking, there might be a risk of a colli- sion sooner or later.

Two system levels Depending on how the car is equipped, the "Collision Warning with Auto Brake and

17 No warning for cyclists with "Level 1".

Cyclist and Pedestrian Detection" function may appear in two variants: Level 1
The driver is merely warned17 of occurring obstacles by means of visual and acoustic signals - no automatic braking intervenes, the driver must himself brake. Level 2
The driver is warned of occurring obstacles by means of visual and acoustic signals - the car is braked automatically if the driver him- self does not act within a reasonable time.

IMPORTANT

Maintenance of the internal components of the "Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" must only be performed at a workshop - an authorised Volvo workshop is recom- mended.

If in this situation the driver has not yet started to take evasive action and the risk of collision is imminent then the automatic brak- ing function is deployed - this takes place irrespective of whether or not the driver brakes. Braking then takes place with full brake force in order to reduce collision speed, or with limited brake force if it is sufficient to avoid a collision. For cyclists, the warning and full brake intervention may come very late or simultaneously.

Audio-visual warning signal in the event of a collision risk. Radar sensor19

Camera sensor

Collision Warning with Auto Brake executes three steps in the following order: 1. Collision warning 2. Brake support19
3. Auto Brake19
The collision warning system and City Safety™ (p. 222) complement each other.

07

1 - Collision warning The driver is first warned of a potentially imminent collision. The collision warning system can detect pedestrians, cyclists or vehicles that are sta- tionary or moving in the same direction in front of the driver's vehicle. If there is a risk of collision with a pedestrian, cyclist or a vehicle then the driver's attention is attracted with a flashing red warning signal (1) and an acoustic signal.

2 - Brake support19
If the risk of collision has increased further after the collision warning then the brake sup- port is activated. This means that the brake system is prepared for rapid braking by applying the brakes lightly, which may feel like a slight jolt. If the brake pedal is depressed sufficiently quickly then full brake function is imple- mented. Brake support also reinforces the driver's braking if the system considers that the brak- ing is not sufficient to avoid a collision.

3 - Auto Brake19
The automatic brake function is activated last.

18 NOTE: The illustration is schematic - details may vary depending on car model. 19 With system Level 2 only.

* Option/accessory, for more information, see Introduction.

WARNING

The collision warning system does not engage in all driving situations or traffic, weather or road conditions. The collision warning system does not react to vehicles or cyclists driving in another direction to the car or to animals. Warning only activated in the event of a high risk for collision. This section "Func- tion" and the section "Limitations" inform about limitations that the driver must be aware of before using the Collision Warn- ing system with Auto Brake. Warnings and brake interventions for pedestrians and cyclists are deactivated at a vehicle speed exceeding 80 km/h. Warnings and brake interventions for pedestrians and cyclists do not work in darkness and tunnels - not even when streetlights are lit. The auto-brake function can prevent a col- lision or reduce collision speed. To ensure full brake performance, the driver should always depress the brake pedal - even when the car auto-brakes. Never wait for a collision warning. The driver is always responsible that the cor- rect distance and speed are maintained - even when the collision warning system with auto-brake is used.

tours, directly from behind and in the car's cen- tre line. Optimal performance of the system requires that the system function that detects a cyclist receives as unambiguous information as pos- sible about the body and bicycle contours - this implies the opportunity to identify the bicycle, head, arms, shoulders, legs, upper and lower body combined with a normal human pattern of movement. If large parts of the cyclist's body or bicycle are not visible to the function's camera then the system cannot detect a cyclist. • For the function to be able to detect a

cyclist, he/she must be an adult and rid- ing an "adult bicycle".

• The bicycle must be equipped with a

highly visible and approved20 rearward- facing red reflector, fitted at least 70 cm above the roadway.

• The function can only detect cyclists

directly from behind and who are travel- ling in the same direction - not at an angle from behind, not from the side.

• Cyclists travelling on the left or right-hand edge of the car's imagined/extended side lines may be detected late or not at all.

• The function's capacity to detect cyclists at dusk and dawn is limited - just like the human eye.

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, for example.

• cyclists in clothing that obscures the

contours of the body or who are approaching from the side.

• In order for a pedestrian to be detected he/she must appear full-length and have a height of at least 80 cm.

• The camera sensor's ability to see pedes-

trians at dusk and dawn is limited - just like the human eye.

• The camera sensor's capacity to detect

pedestrians is deactivated when driving in darkness and tunnels - even when street- lights are lit.

WARNING

"Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is a means of assistance. The function cannot detect all pedestrians in all situations and does not see, for example: • partially obscured pedestrians, people in clothing that hides their body con- tour or pedestrians shorter than 80 cm.

• pedestrians who are carrying larger

objects.

The driver is always responsible that the vehicle is driven properly and with a safety distance adapted to the speed.

Warning signals On and Off

1. Acoustic and visual warning signal in the event of a collision risk.21
You can select whether the collision warning system's acoustic and visual warning signals should be switched on or off. When starting the engine, the setting that was selected when the engine was switched off is obtained automatically.

NOTE

The Brake Support and Auto Brake func- tions are always enabled - they cannot be deactivated.

07 Driver support

• Search for Warning distance in

Collision warning in the menu system MY CAR (p. 114) - and there select Long, Normal or Short.

The warning distance determines the sys- tem's sensitivity. Warning distance Long pro- vides an earlier warning. First test with Long and if this setting produces too many warn- ings, which could be perceived as irritating in certain 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 will be used by the cruise control even if the collision 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 driver reaction time. In order for the collision warning system to be effective, always drive with Distance Warning (p. 219) set at time interval 4–5.

Settings for the collision warning system are made via the centre console's screen and the menu system MY CAR, see (p. 114). Light and acoustic signals When the collision warning system's light and acoustic warnings are activated, the warning lamp (no. [1] in previous illustration) is tested each time the engine is started by briefly illu- minating the warning lamp's separate points of light. After starting the engine, both the light and acoustic signals can be switched off: • Search for Collision warning in Driver

support system in the menu system MY CAR (p. 114) - and there select to uncheck the function.

Acoustic signal After starting the engine the warning sound can be activated/deactivated separately: • Search for Warning sound in Collision warning in the menu system MY CAR (p. 114) - and there select On or Off.

Following which, the collision warning system is only indicated with a light signal.

Set warning distance The warning distance regulates the distance at which the visual and acoustic warnings are deployed.

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 if vehicles in front brake heavily.

WARNING

No automatic system can guarantee 100 % correct function in all situations. Therefore, never test Collision Warning with Auto Brake by driving at people or vehicles - this may cause severe damage and injury and risk lives.

Checking settings The current settings can be controlled via the centre console's screen and the menu sys- tem (p. 114) MY CAR.

Maintenance

Camera and radar sensor22. For the sensors to work correctly, they must be kept clear of dirt, ice and snow, and be cleaned regularly with water and car sham- poo.

NOTE

Dirt, ice and snow covering the sensors will reduce their function and may prevent measurement.

Related information • Collision warning system* (p. 229)

Collision warning system* - limitations 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. 230)) may be difficult to notice in the event of strong sunlight, reflections, when sunglasses are being worn or if the driver is not looking straight ahead. The warning sound should therefore always be activated. On slippery road surfaces the braking dis- tance is extended, which may reduce the capacity to avoid a collision. In such situa- tions the ABS and ESC (p. 191) systems will provide best possible braking force with maintained stability.

NOTE

The visual warning signal can be temporar- ily disengaged in the event of high passen- ger compartment temperature caused by strong sunlight for example. If this occurs then the warning sound is activated even if it is deactivated in the menu system. • Warnings may not appear if the dis-

tance to the vehicle in front is small or if steering wheel and pedal move- ments are large, e.g. a very active driv- ing style.

22 NOTE: The illustration is schematic - details may vary depending on car model.

WARNING

Warnings and brake interventions could be implemented late or not at all if the traffic situation or external influences mean that the radar or camera sensor cannot detect a pedestrian, a vehicle or a cyclist in front correctly. The sensor system has a limited range for pedestrians and cyclists23 - the system can provide effective warnings and brake interventions for them at vehicle speeds up to 50 km/h. For stationary or slow-moving vehicles, warnings and brake interventions are effective at vehicle speeds up to 70 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 at vehicle speeds exceeding 80 km/h.

The collision warning system uses the same radar sensors as the Adaptive cruise control (p. 204). Read more about radar sensor limi- tations (p. 214). If warnings are perceived as being too fre- quent or disturbing then the warning distance can be reduced (p. 233). This would lead to the system warning at a later stage, which reduces 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 is why the system does not intervene in situa- tions where the car is approaching a vehicle in front very slowly, e.g. when parking. In situations where the driver demonstrates active, aware driving behaviour, a collision warning may be postponed slightly in order to keep 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 the car is braked for a vehicle in front that is mov- ing, then speed is reduced to the same speed as 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 the clutch pedal beforehand.

23 For cyclists, the warning and full brake intervention may come very late or simultaneously.

07 Driver support

Collision warning system* - camera sensor limitations "Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is an aid to assist the driver when there is a risk of collid- ing with a pedestrian, bicycle or vehicle in front that are stationary or moving in the same direction. 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: • Active main beam (p. 93) • Road sign information (p. 195) • Driver Alert Control - DAC (p. 239) • Lane assistance (p. 242)

NOTE

Keep the windscreen surface in front of the camera sensor free from ice, snow, mist and dirt. Do not stick or attach anything to the windscreen in front of the camera sensor as this may reduce effectiveness or cause one or more of the systems dependent on the camera to stop working.

* Option/accessory, for more information, see Introduction.

07 Driver support || The camera sensors have limitations similar to the human eye, i.e. they "see" worse in darkness, heavy snowfall or rain and in thick fog for example. Under such conditions the functions of camera-dependent systems could be significantly reduced or temporarily disengaged. Strong oncoming light, reflections in the car- riageway, snow or ice on the road surface, dirty road surfaces or unclear lane markings could also significantly reduce camera sensor function 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 and vehicles 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 minutes after the engine is started in order to protect camera functionality.

Fault tracing and action If the display shows the message Windscreen sensors blocked See manual then this means that the camera sensor is blocked and cannot detect pedestrians, cyclists, vehicles or road markings in front of the car.

07

At the same time, this means that - besides Collision Warning with Auto Brake - the fol- lowing functions will not have full functionality either: • Active main beam • Driver Alert Control • Lane Keeping Aid • Road sign information The following table presents possible causes for a message being shown along with the appropriate action.

Cause

Action

The windscreen surface in front of the camera is dirty or covered with ice or snow.

Clean the wind- screen surface in front of the camera from dirt, ice and snow.

Thick fog, heavy rain or snow means that the camera does not work suffi- ciently well.

No action. At times the camera does not work during heavy rain or snow- fall.

Cause

Action

The windscreen surface in front of the camera has been cleaned but the message remains.

Dirt has appeared between the inside of the windscreen and the camera.

Wait. It may take several minutes for the camera to measure the visibil- ity.

Visit a workshop to have the wind- screen inside the camera cover cleaned - an author- ised Volvo work- shop is recom- mended.

Driver Alert System* The Driver Alert System is intended to assist drivers whose driving ability is deteriorating or who are inadvertently leaving the lane they are driving on.

The Driver Alert System consists of different functions which can either be switched on at the same time or individually: • Driver Alert Control - DAC (p. 240). • Lane Departure Warning - LDW (p. 242). or • Lane Keeping Aid - LKA (p. 246) A switched-on function is set in standby mode and is not activated automatically until speed exceeds 65 km/h. The function is deactivated again when speed decreases to below 60 km/h. Both functions use a camera which is dependent on the lane having side markings painted on each side.

WARNING

Driver Alert System does not work in all situations but is designed merely as a sup- plementary aid. The driver always bears ultimate responsi- bility for ensuring that the vehicle is driven safely.

07 Driver support

Driver Alert Control (DAC)* The DAC function is intended to attract the driver's attention when he/she starts to drive less consistently, e.g. if he/she becomes dis- tracted or starts to fall asleep.

The objective for DAC is to detect slowly deteriorating driving ability and it is primarily intended for major roads. The function is not intended for city traffic.

A camera detects the side markings painted on the carriageway and compares the section of the road with the driver's steering wheel movements. The driver is alerted if the vehicle does not follow the carriageway evenly. In some cases driving ability is not affected despite driver fatigue. In which case there may not be any warning issued for the driver. For this reason it is always important to stop and take a break in the event of any signs of

Lane Departure Warning (LDW)* The purpose of Lane Departure Warning (Lane Departure Warning) is to help the driver to reduce the risk of the vehicle accidentally leaving its own lane in certain situations on motorways and similar major routes.

Lane Departure Warning LDW or LKA There are two versions of Lane assistance: • LDW - Lane Departure Warning - alerts the driver with an acoustic signal or vibra- tion in the steering wheel. • LKA - Lane Keeping Aid

(Lane Keeping Aid) - steers the car back into its lane and/or alerts the driver with an acoustic signal or vibration in the steering wheel.

The car is supplied with one of these two sys- tems - market and engine alternative deter- mine which of the systems the car is equip- ped with. In the event of uncertainty whether the car has LDW or LKA: • Open the menu system MY CAR and locate Driver support system - which specifies Lane Departure Warning if the car has LDW or Lane Keeping Aid for LKA.

07

Principle for LDW

(The figure is schematic - not model specific.) A camera reads the side lines of the road/ lane.

Warning with steering wheel vibration24.

If the car crosses one of the side lines the driver is alerted with an acoustic signal or vibration in the steering wheel. Steering wheel vibration varies - the longer the time for which the car has crossed the side line, the longer the vibration.

NOTE

The driver is only warned once each time the wheels cross a line. So there is no acoustic alarm when there is a line between the car's wheels.

WARNING

Lane assistance is merely a driver aid and does not engage in all driving situations or traffic, weather or road conditions. The driver always bears ultimate responsi- bility for ensuring that the vehicle is driven safely and that applicable laws and road traffic regulations are followed.
