| Operation of tyre pressure monitoring system |
| The tyre pressure monitoring system is operated via the steering column lever or the operating unit in the centre console. |
| The system monitors the tyre inflation pressures that have been set by the operator and stored as reference values. |
| –
| The inflation pressures must first be checked and corrected before being stored in the system. |
