Before vehicle lift will become active, the
engine must be running or the vehicle must
be in E-Mode (see E-Mode, page 2.16). To
raise the vehicle, select the vehicle lift menu
(see Accessing the Menu, page 3.21) and then
move the menu control stalk upwards.
The change in vehicle ride height is
confirmed by an ascending audible tone.
'Vehicle Raising' appears in the left-hand side
of the central screen display and the vehicle
lift icon will flash.
If the ignition is turned off while the vehicle is
raising, the system will stop and continue to
raise only when the engine is restarted or
E-Mode activated.
