The tyre pressure monitoring system (TPMS) senses change in radius of the tyre. If the tyre pressure decreases below the recommended pressure, the system warning light will be illuminated.
For the system to function properly, it is the driver’s responsibility to set the system by following accurate procedure and set current tyre pressure.
The warning light will illuminate on the cluster when one or more of your tyres is under-inflated after the TPMS is set. The warning light will also illuminate to warn the driver of system malfunction. Please refer to the above image (1) for further information.
