seated occupant and determine if the passeng- er's side front airbag should be enabled (mayinflate) or disabled (will not inflate). The OWS will disable (will not inflate) the pas- senger's side front airbag when:
• the front passenger's seat is unoccupied, orhas small/medium objects in the front seat,
• the system determines that an infant is pres-ent in a rear-facing infant seat that is instal-led according to the manufacturer's instruc-tions,
• the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufactur-er's instructions,
• the system determines that a small child ispresent in a booster seat,
• a front passenger takes his/her weight off ofthe seat for a period of time,
• a child or a small person occupies the frontpassenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stay on toremind you that the passenger's side front airbagis disabled. The PASSENGER AIRBAG OFF indi-cator lamp is located in the overhead console,near the base of the rearview mirror.
NOTE
When the ignition is switched on, the OWS indicator light will illuminate for several sec-onds while the system performs a self-diag-nostic test.
However, if a fault is detected in the system:
• The OWS indicator light will stay on
• The SRS warning light will come on and stay on and a text message will be displayed.
WARNING
If a fault in the system is detected and indi- cated as described, be aware that the pas-senger's side front airbag will not deploy inthe event of a collision. In this case, the SRSsystem and Occupant Weight Sensor shouldbe inspected by a trained and qualified Volvoservice technician as soon as possible.
WARNING
• Never try to open, remove or repair any components in the OWS system. Thiscould cause the system to malfunction.Maintenance or repairs should only becarried out by an a trained and qualifiedVolvo service technician.
• The front passenger's seat should not bemodified in any way. This could reducepressure on the seat cushion, whichmight interfere with the OWS system'sfunction.

Climate comfort retaining function
The climate in the passenger compartment can be maintained when the vehicle is parked, e.g. ifthe engine is turned off but the driver or passen-gers remain in the vehicle.
This function can only be direct-started. The function utilizes several of the vehicle's sys- tems:
• Residual heat from the engine is used tohelp heat the passenger compartment to acomfortable temperature.
• In warm weather, the ventilation system coolsthe passenger compartment by blowing air infrom outside.
NOTE
Climate comfort maintenance will be deacti- vated if the vehicle is locked from the outsidein order to avoid using residual engine heatunnecessarily. This function is intended to beused to maintain climate comfort when thedriver or a passenger remains in the vehicleafter the engine is turned off.

WARNING
•The radar sensor has a limited field of vision. In some situations, it may detect avehicle later than expected or not detectother vehicles at all.
• The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
• The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
• Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
• Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see. Poorweather or winding roads can affect theradar sensor's capacity to detect vehiclesahead.
• A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
•High speeds may also result in the warn- ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

* (p. 291)
Adaptive Cruise Control *
Adaptive Cruise Control (ACC 41
) helps the
driver maintain a constant speed with a set time interval to the vehicle ahead.
Adaptive Cruise Control helps provide a more relaxed driving experience on long trips on high-ways or long, straight roads with even trafficflows.
The camera/radar sensor measures the distance to the vehicle ahead 42
.
The driver sets a speed and a time interval to the vehicle ahead. If the camera/radar sensor detects a slower-moving vehicle ahead, your vehicle's speed will be automatically adapted according to the set time interval to that vehicle. When thereare no longer slower-moving vehicles ahead, thevehicle will return to the set speed.

WARNING
•The Adaptive Cruise Control function is supplementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Adaptive Cruise Control is not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
NOTE
Depending on market, this function may be either Standard or Optional.
Adaptive Cruise Control regulates speed by accelerating and braking. It is normal for the brakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts to regu- late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, when there are great differences inspeed between vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).
WARNING
• Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
• Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
CAUTION
Maintenance of Adaptive Cruise Control com- ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.

WARNING
•The Pilot Assist function is supplementary driver support intended to facilitate driv-ing and help make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Pilot Assist should only be used if thereare clear lane lines painted on each sideof the lane. All other use will increase therisk of contact with nearby obstacles thatcannot be detected by the functions.
• Pilot Assist is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theproper position within the lane, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
NOTE
Depending on market, this function may be either Standard or Optional.
Pilot Assist regulates speed by accelerating and braking. It is normal for the brakes to emit a slightsound when they are being used to adjust speed. Pilot Assist attempts to smoothly regulate speed. The driver must apply the brakes in situationsrequiring immediate braking. For example, whenthere are great differences in speed betweenvehicles or if the vehicle ahead brakes suddenly.Due to limitations in the camera and radar sen-sor, braking may occur unexpectedly or not at all. Pilot Assist is designed to follow a vehicle ahead in the same lane and maintain a time interval tothat vehicle set by the driver. If the radar sensordoes not detect a vehicle ahead, it will insteadmaintain the speed set by the driver. This will alsohappen if the speed of the vehicle aheadexceeds the set speed for your vehicle.
• Pilot Assist can follow another vehicle atspeeds from a standstill up to 200 km/h(125 mph).
• Pilot Assist can provide steering assistancefrom near-stationary speeds up to 140 km/h(87 mph).
WARNING
• Pilot Assist is not a collision avoidance system. The driver must intervene if thesystem fails to detect a vehicle ahead.
• Pilot Assist does not brake for people,animals, objects, small vehicles (e.g.cycles and motorcycles), low trailers aswell as oncoming, slow or stationary vehi-cles.
• Do not use Pilot Assist in demanding sit-uations, such as in city traffic, at intersec-tions, on slippery surfaces, with a lot ofwater or slush on the road, in heavy rain/snow, in poor visibility, on winding roads,on highway on- or off-ramps, or with atrailer connected to the vehicle.
CAUTION
Maintenance of the integrated components in Pilot Assist may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.
In curves and forks in the roadPilot Assist is designed to interact with the driver. The driver should never wait for steering assis-tance from Pilot Assist, but instead should alwaysbe ready to increase his or her own steeringefforts, particularly in curves.
