Tire pressure monitoring
Atto 3
- Color
- Amber
- Urgency
- Check soon
Most lamps light for a few seconds when you power the car on. That check is not a fault by itself. This page does not replace the owner’s manual for your model year and market. Icons are schematic illustrations used on this site. They are not offered as the vehicle maker’s artwork, and they have not been checked against it. They may not match the lamp on your cluster. Urgency levels are this site’s classification, not the maker’s. If they differ from the manual, follow the manual.
What it means
This lamp watches the tire-pressure sensors. It lights in the start-up check and should go out. If it stays on or flashes, and the cluster shows dashes or asks you to check the system, the monitor itself is faulty or has lost a signal. A fast flash with a pressure reading in red means that tire is losing air quickly. A steady lamp with a yellow pressure reading means that tire is low. A yellow temperature reading means that tire is too hot.
What to do
If a reading is red or the lamp is flashing quickly, stop and deal with that tire before you drive on. If a reading is yellow, inflate to the pressure on the door placard when the tire is cold, then confirm the warning clears. If every reading is missing, or the lamp returns with normal pressures, have the sensors checked. A pressure fault also lengthens stops, so leave more room until it is corrected.

Common questions
- The lamp is on but the tires look fine. Can I ignore it?
- A tire can be low without looking flat. Read the pressures on the cluster. Yellow means low, red means a fast leak, and dashes mean the system is not reporting. Set the cold pressures to the placard, or stop if one tire is losing air quickly.
- I corrected the pressure and the lamp is still on.
- Drive a short distance so the sensors report again. If the lamp stays on with pressures at the placard value, the monitor or a sensor needs a check. Do not keep adding air above the placard to force the lamp off.
