Volvo recommends that children always be properly restrained in appropriate child restraints in the rear seats.Do not assume that the passenger's side front airbag is dis-abled unless the PASSENGER AIRBAG OFF indicator lampis lit. Make sure the child restraint is properly installed. Ifthere is any doubt as to the status of the passenger's sidefront airbag, move the child restraint to the rear seat.
The OWS is designed to enable (may inflate) the passenger's side front airbag in the eventof a collision anytime the system senses that aperson of adult size is sitting properly in thefront passenger's seat. The PASSENGER AIR-BAG OFF indicator lamp will be off andremain off. If a person of adult size is sitting in the front passenger's seat, but the PASSENGER AIR- BAG OFF indicator lamp is on, it is possiblethat the person isn't sitting properly in theseat. If this happens:
Turn the vehicle off and ask the person toplace the backrest in an upright position.
Have the person sit upright in the seat,centered on the seat cushion, with theperson's legs comfortably extended.
Restart the vehicle and have the personremain in this position for about twominutes. This will allow the system todetect that person and enable the pas-senger's frontal airbag.
If the PASSENGER AIRBAG OFF indica-tor lamp remains on even after this, theperson should be advised to ride in therear seat.
This indicates limitations in OWS classifica-tion capability. It does not indicate OWS mal-function.ModificationsIf you are considering modifying your vehiclein any way to accommodate a disability, forexample by altering or adapting the driver's orfront passenger's seat(s) and/or airbag sys-tems, please contact Volvo at: In the United StatesVolvo Car USA, LLCCustomer Care Center

There are "blind" sectors between the cameras' fields of vision.
With Park Assist Camera's 360° view *
selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual cameraviews meet.
WARNING
Even if it seems as though only a fairly small section of the screen image isobstructed, this may mean that a relativelylarge sector is hidden and obstacles theremay not be detected until they are verynear the vehicle.
Defective camera
If a camera sector is dark and contains this symbol, thisindicates that the camera isnot functioning properly. See the following illustration for an example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed in the following situations, but without the
defective camera symbol: a door is open
the tailgate is open
a rearview mirror is folded in
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions.This means that the brightness and quality of the image may vary slightly. Poor lighting con-ditions may result in reduced image quality.
