The driver can manually select, using the air suspension switch, one of four ride states:
- NORMAL - this height is the normal operating height of the vehicle.
- OFF ROAD - this is higher than the on road height and provides improved ground clearance, approach, departure and break-over angles up to speeds of 80 km/h (50 mph).
- ACCESS - this is lower than the on road height and provides easier access, egress and the vehicle loading.
- Locked at access - this allows the vehicle to be driven at the access height at speeds up to 40 km/h (25 mph) to provide increased roof clearance in low car parks, for example.
Vehicle height changes are restricted if the Chassis Control Module (CHCM) receives a 'door open' signal and the speed is less than 8 km/h (5 mph).
A complete vehicle delivery mode is available but is only selectable using the Jaguar Land Rover approved diagnostic system. When this mode is active most vehicle systems, in addition to the air suspension, are inhibited or restricted to a minimal functionality. In this mode the air suspension is set to the transportation mode.
If the CHCM senses that the vehicle has grounded and lost traction, the CHCM can temporarily raise the vehicle to maximize the available traction.
This is known as extended mode and will be indicated to the driver:
- By the lamps on the air suspension switch flashing.
- By an 'EXTENDED MODE' message being displayed in the Instrument Cluster (IC).
If a fault is detected by the CHCM, it will reduce the system functionality dependent on the type and severity of the fault. The CHCM will also store a fault code which can be retrieved using the Jaguar Land Rover approved diagnostic system. If a severe fault occurs, the CHCM will attempt to put the vehicle in a safe condition. A fault is relayed to the driver by the IC message center and an audible warning emitted from the IC.
All information messages will be displayed for four seconds.
