LR3/Disco 3
the warning indicator is illuminated. The indicator will change to an amber color and the audible warning will stop when
the vehicle speed is reduced.
On-Road Mode
This is the normal ride height for the vehicle.
Off-Road Mode
Off-road mode will only be activated if the vehicle speed is less than 25 mph (40 km/h). The vehicle will be raised 55 mm
(2.2 in) higher than the on-road mode to provide additional body clearance and improved approach, departure and
breakover angles. If the vehicle speed exceeds 31 mph (50 km/h), the air suspension control module will automatically
lower the vehicle to the on-road mode height. At 25 to 28 mph (40 to 45 km/h) a message is displayed in the message
center to warn the driver to slow down or the vehicle will lower.
NOTE:
Access Mode
Access mode lowers the vehicle body height by 50 mm (2 in) and provides easier entry, exit and loading of the vehicle.
Access mode can be pre-selected when the vehicle is moving. The vehicle will partly lower as the vehicle speed
decreases, lowering to the full access mode height when the vehicle reaches 5 mph (8 km/h). If the required road speed
is not reached within a predetermined time, the air suspension will return the vehicle to the previously selected height.
Access mode can be selected at any vehicle speed. When access mode is selected, the response of the air suspension
system will depend on the vehicle speed:
l
If the vehicle speed is more than 12.5 mph (20 km/h), the air suspension control module will wait for up to one
minute for the vehicle speed to be reduced. The access mode lamp and the lowering lamp will flash while the air
suspension control module waits for the vehicle speed to be reduced, the on-road mode lamp will remain
illuminated. If the vehicle speed is not reduced sufficiently, the access mode request will be cancelled after 1
minute.
l
If the vehicle speed is less than 12.5 mph (20 km/h), the air suspension control module will lower the suspension
to a part lowered height and will remain at this height for up to one minute. The on-road mode lamp will extinguish
as the air suspension control module lowers the suspension to the part lowered height. The access mode lamp
and the lowering lamp will illuminate. When part lowered is reached, the 'lower' lower lamp will flash. If the vehicle
speed is not reduced to less than 5 mph (8 km/h) in the one minute period, the access mode request will be
cancelled.
l
If the vehicle speed is less than 5 mph (8 km/h), the suspension will be lowered to access mode immediately. The
access mode lamp and the lowering lamp will illuminate. When the access mode height is reached, the lowering
lamp will be extinguished.
Access height may be selected up to 40 seconds after the ignition is turned off, provided that the driver's door has not
been opened within this time.
The suspension will automatically rise from access mode when the vehicle speed exceeds 6.2 mph (10 km/h). If access
mode was selected directly from off-road mode then the system will return to off-road mode when the vehicle speed
exceeds 6.2 mph (10 km/h). Otherwise the system will lift the suspension to On -road height.
Selecting Access Mode Directly from Off-Road Mode
When the suspension is in off-road mode height, pressing the air suspension switch once and then a second time before
the lowering lamp is extinguished, the control module will lower the suspension to access mode height. The control
module will remember to return the suspension to off-road height automatically if the vehicle speed increases above 6.2
mph (10 km/h).
Crawl (Locked at Access) Mode
The suspension can be automatically set to off-road mode when some Terrain Response programs and low range
are selected.
