Volvo XC60 Warning Lights: What They Mean

Red: stop or act now

SRS warning light

A fault was detected in the Occupant Weight Sensor/SRS system; the passenger's side front airbag will not deploy in a collision.
What to do: Have the SRS system and Occupant Weight Sensor inspected by a trained, qualified Volvo technician as soon as possible. PDF page 62

Alarm indicator

Flashing once every two seconds means the alarm is armed; quick flashing means the alarm was triggered. PDF page 275

Other warnings and indicators

Low tire pressure telltale

One or more tires are significantly under-inflated.
What to do: Stop and check your tires as soon as possible, and inflate them to the proper pressure. PDF page 548

TPMS malfunction indicator

Flashes about one minute, then stays lit when the tire pressure system is faulty; low pressure may go undetected.
What to do: Check it after replacing tires or wheels to make sure they allow the TPMS to work properly. PDF page 548

OWS indicator light

Lit when the passenger seat is empty or has a low-weight occupant, so the passenger front airbag is disabled. Staying lit signals a fault.
What to do: If a fault is shown, have the system inspected by a trained, qualified Volvo technician as soon as possible. PDF page 62

Summarized in our own words from the 2021 Volvo XC60 owner's manual (AI-assisted; every light name was matched against its cited page 2026-10-18). Your vehicle may not have every light, and other years can differ. A red warning that stays on usually means stop safely and check: your manual has the final word.
