I looked in the manual but didn't see an auto access height when in park mode? Is this possible?

 

Good question, Id like to know as well

 

LR3 workshop manual only describes the key fob operated raising/lowering of the vehicle.

See Note 2 from the manual:

OPERATING MODES

The driver can manually select, using the air suspension switch, one of four ride states:

l ON-ROAD - this height is the normal operating height of the vehicle

l OFF-ROAD - this height is higher than the on-road height and provides improved ground clearance, approach,
departure and breakover angles

l ACCESS - this height is lower than the on-road height and makes entering and exiting the vehicle easier for the
occupants

l CRAWL (Locked at access) - this height allows the vehicle to be driven at the access height at low speeds to provide increased roof clearance in low car parks etc.

NOTE: Vehicle height changes are prevented if the air suspension control module receives a 'Door Open' signal from the Central Junction Box (CJB).

An additional 'TRANSPORTATION' mode is also available but is only selectable using T4.

Note 2: An additional function allows the vehicle to be raised or lowered from outside of the vehicle when the vehicle is stationary. This assists with the attachment of a trailer and is achieved using the buttons on the remote handset and the ignition switch in the off position. The remote handset can be programmed to perform a number of additional functions.
