Tire Pressure Warning Light

What it means

One or more tires are below the recommended pressure, or the tire pressure monitoring system itself has a fault. An underinflated tire raises the risk of a blowout, particularly in summer heat and at high speed.

Symptoms4

• A steady light with one tire looking lower than the others.
• The car pulls to one side.
• Vibration or heavy steering.
• The light flashes for a while and then stays on, which usually indicates a system fault.

Possible causes5

• Natural pressure loss over time or with temperature changes.
• A nail or small puncture in the tire.
• A leak at the valve or the rim edge.
• A dead battery in a tire pressure sensor.
• Sensors not relearned after swapping wheels.

How to diagnose and fix5

1. Measure the pressure in every tire with a gauge while the tires are cold.
2. Set the pressure to the value on the sticker in the driver door frame.
3. Inspect the low tire for a nail or puncture.
4. Patch or replace the tire depending on where the damage is.
5. If the light flashes, have the sensors checked or relearned.

Repair cost

In Saudi riyals; the highlighted part is the expected range for this fault.

Adjusting pressure or patching a tire is cheap, while a new sensor or tire costs a little more.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.
