The tyre pressure warning light illuminates on the Ford Focus often due to tyre pressure falling 25% or more below the threshold allowance in one or more tyres. Before resetting the tyre pressure monitoring system (TPMS), check pressure in all tyres including the spare if you have one.
If the tyre pressure light comes on particularity when it’s cold, this is because air pressure is lower when cold and once the tyre has warmed, the light should go out. To stop the warning light coming on, add a little air to the tyres, being careful not to over-inflate.
If you have checked pressures and they are correct, but the light still illuminates, you may have a faulty pressure sensor, or a dead battery in one of the pressure sensor modules. If this is the case, the entire unit within the tyre will need to be replaced.
In order to reset the tyre pressure warning light in the Ford Focus, you’ll need to use the navigation buttons on the steering wheel and follow the menu on the display screen.
To reset the tyre pressure light on your Ford Focus, follow these instructions:
- Press the up / down arrow buttons to scroll through the menu to highlight Settings and press OK.
- Scroll through to Driver Assist and press OK.
- Scroll down to Tyre Monitor and press OK.
- Now press and hold OK.
- Keep the OK button pressed down and wait for the message: ‘Tyre Pressure Stored‘.
Tyre Pressure Warning Light Reset Alternative Method
If the above method does not work and you have no other faults, or you do not have the option for the above method, you can try this alternative method.
- Turn the ignition to the ON position.
- Quickly push the hazard warning light button 6 times within 5 seconds until you hear the horn sound.
- The console screen will now display the message ‘Train left front tyre‘. Now slowly deflate the left front tyre until you hear the horn sound.
- Slowly deflate air from the right front tyre until you hear the horn sound.
- Slowly deflate air from the rear right tyre until you hear the horn sound.
- Slowly deflate air from the rear left tyre until you hear the horn sound.
- A message on the console screen saying: ‘Training complete’ should now appear.
- The tyre pressure monitoring system and light will now be reset. Now inflate all tyre back up to the recommended tyre pressure.
The tyre pressure monitoring system will now have been reset on the Ford Focus and the warning light should go out. If the light continues to come on, check for a tyre leak or possible fault with a TPMS in one of the tyres. For further help regarding the TPMS, see tyre pressure light keeps coming on.
