XC40 Occupant Classification System

P5-1507-USA-occupant weight sensor — OCS indicator light.

The front passenger-side airbag is either enabled or disabled depending on the classification of the passenger in the front passenger seat.

Volvo follows NHTSA's recommendations and recommends that ALL children up to and including 12 years of age sit in the rear seat and are restrained in a suitable manner appropriate to their height and weight. This is strongly recommended for children in rear-facing child seats.

Occupant Classification System function

OCS works in combination with sensors in the front passenger seat. The sensors are intended to detect the presence, and classification of, an occupant sitting correctly and determine whether the front passenger airbag should be enabled (able to be deployed) or disabled (cannot be deployed).

The OCS uses an indicator light with the text PASSENGER AIRBAG OFF, which will illuminate and stay on to remind you that the passenger's side front airbag is disabled. The PASSENGER AIRBAG OFF indicator light is located in the ceiling console near the bracket for the rearview mirror.

Always pay attention that the status of the indicator light shows the correct classification both before and while driving when the front passenger seat is occupied.

Note

When the ignition is switched on, the OCS indicator light will illuminate for several seconds while the system performs a self-diagnostic test. The indicator light will then go out or remain illuminated, depending on the classification of the passenger in the front passenger seat.

If a malfunction is detected in the system, the OCS indicator light will remain illuminated and the SRS warning symbol will be shown in the instrument panel along with a text message.

Warning

If a fault in the system is detected and indicated as described, be aware that the passenger's side front airbag will not deploy in the event of a collision. If this occurs, have the airbag system and Occupant Classification System checked by a workshop as soon as possible. Volvo recommends contacting an authorized Volvo workshop.

Classification of adult

To help ensure accurate classification when a person of adult size is sitting in the front passenger seat, the passenger must:

be wearing their seat belt
sit normally in the seat, in the center of the seat cushion
sit upright in the seat with their shoulders against the backrest
have their legs comfortably extended with their feet on the floor.

P6-1746-XC40–Safety–Occupant Classification System correct seating — Correct seating position.

P6-1746-XC40–Safety–Occupant Classification System seating 1 — Example of incorrect seating position - the passenger must not have slid forward on the seat cushion.

P6-1746-XC40–Safety–Occupant Classification System seating 2 — Example of incorrect seating position - the passenger must be seated with their feet on the floor.

P6-1746-XC40–Safety–Occupant Classification System seating 3 — Example of incorrect seating position - the passenger must not fold the backrest to a lying position.

Remember the following when an adult sits in the front passenger seat:

The passenger must never get up from the seat cushion using the armrest in the door or center console, by pushing their feet against the floor or by pushing against the backrest.
The passenger must never sit on the side of the seat cushion, slide forward on the seat cushion or fold the backrest to a lying position.
The passenger must never wear wet or thick clothing, e.g. ski wear or padded garments.
Never place any objects between the passenger and the seat cushion, e.g. pillows, heating blankets or ordinary blankets, seat liners or mats.
Never place a radio transmitter (e.g. hunting radio or walkie-talkie) or device that is being charged (e.g. cellular phone, tablet or computer) on or under the seat cushion. Never let anyone sitting on the passenger seat use a radio transmitter or device that is being charged.

Warning

Failure to follow the above instructions could adversely affect the Occupant Classification System functions and result in death or serious injury.

If a person of adult size is sitting in the front passenger's seat, but the OCS indicator lamp is on, it is possible that the person isn't sitting properly in the seat.

If this occurs, turn off the vehicle and ask the person to follow the above instructions for accurate classification. Restart the vehicle and have the person remain in this position for about two minutes. This will allow the system to detect that person and enable the passenger's frontal airbag.

If the OCS indicator lamp remains on even after this, the person should be advised to ride in the rear seat.

This may indicate restrictions in the OCS classification ability, e.g. that the person is too light to be classified as an adult. It does not need to indicate an OCS error.

Classification of child

Volvo follows NHTSA's recommendations and recommends that ALL children up to and including 12 years of age sit in the rear seat. This is strongly recommended for children in rear-facing child seats.

If a child in a child restraint is placed in the front passenger seat, the child restraint must be installed according to the manufacturer's instructions to help ensure accurate classification.

Remember the following if a child in a child seat sits in the front passenger seat:

Never place any items or accessories on the passenger seat, between the child seat and the seat cushion or near to the seat cushion.
Never place a radio transmitter (e.g. hunting radio or walkie-talkie) or device that is being charged (e.g. cellular phone, tablet or computer) on the seat cushion. Never let anyone sitting on the passenger seat use a radio transmitter or device that is being charged.
Never place wet clothing or fluids on the passenger seat.
Always correctly position the child seat so that the entire lower section of the child seat rests against the seat cushion.
Always place a front-facing child seat as far back as possible against the seat back.

Warning

Failure to follow the above instructions could adversely affect the Occupant Classification System functions and result in death or serious injury.
