Keeping your tyres at the correct pressure is an important part of vehicle maintenance, helping you save fuel, preserve the condition of your tyres, and – most importantly – stay safe. The tyre pressure monitoring system constantly monitors the air pressure of each tyre and reports any loss of pressure that’s detected. If a problem is detected, a warning appears on the dashboard.
There are two types of TPMS that are in use: direct and indirect. Direct systems offer an accurate reading of the pressure in each tyre, while indirect works with the anti-lock braking system to detect whether the wheels are rolling at different speeds. This is a sign of under-inflated tyres and will trigger the warning light on the dash.
In the event of the symbol being illuminated, pull over at the nearest safe place and check your tyres. Then either re-inflate at a local petrol station or replace the tyre with your spare until you can top up your under-inflated tyre.
