DESCRIPTION AND OPERATION
HEIGHT SETTINGS
Standard ride height
With the Inhibit switch off (unlatched), at speeds
below 80 km/h (50 mph) the standard ride height
indicator will be illuminated.
Standard vehicle ride height is maintained under all
load conditions. This also maintains headlamp
levelling.
Low ride height
Low ride height is automatically selected when the
vehicle speed exceeds 80 km/h (50 mph) for at least
30 seconds with the inhibit switch off. Low ride height
indicator lamp will flash during height change and
standard ride height indicator will extinguish when low
ride height is attained.
Standard ride height is automatically selected when
the vehicle speed drops below 56 km/h (35 mph) for
at least 30 seconds with the inhibit switch off.
The driver can select low ride height at any speed.
With the vehicle at low ride height, depressing the
inhibit switch (latched) will result in the vehicle
maintaining low ride height regardless of speed.
The height control switch can be used to change
between low and standard ride heights regardless of
speed.
Access mode
This position eases access to and from the vehicle.
With the vehicle stationary, doors and tailgate closed,
park brake applied, foot brake released and gearshift
in ’Park’ on automatic vehicles, press and release the
down switch. The vehicle will descend to access
mode. While the vehicle is descending, the access
indicator will flash. When access mode is attained, the
indicator will remain constantly illuminated, and
standard ride height lamp will be extinguished.
Access mode can be selected up to 40 seconds
before stopping vehicle. On stopping, applying the
handbrake, releasing the foot brake and selecting
’Park’ on automatic vehicles, the vehicle will lower to
access mode.
It is possible to select access up to 40 seconds after
switching engine off.
NOTE: Opening a door or tailgate will
immediately stop vehicle height change.
When the door is closed, the height
change will be completed. If the door is open for
more than thirty seconds, the system will need
’reminding’ of the new height when the door is
closed.
Driving the vehicle will result in vehicle rising
automatically to standard ride height. Alternatively
standard ride height can be achieved by closing all
doors, starting engine and pressing the up switch. The
standard indicator will flash during the change. When
standard ride height is attained the indicator will
remain constantly illuminated and access indicator will
be extinguished.
Crawl mode
In areas where height is restricted, the vehicle may be
driven in access mode. To achieve this, ensure the
inhibit switch is unlatched and select access mode.
When access height is achieved, press the inhibit
switch, the lamp will be illumunated. The message
centre in the instrument binnacle will beep three times
and display AIRSUS ISOLATED. The vehicle may
now be driven at speeds up to 32 km/h (20 mph).
If the vehicle is accelerated to 16 km/h (10 mph) the
message centre will beep three times and display
SLOW 20 MPH (32 KM/H) MAX.
If speed exceeds 40 km/h (25 mph) the vehicle will
rise to low profile, with low warning flashing. On
slowing to 32 km/h (20 mph) the vehicle will lower to
access mode with access warning illuminated.
When speed falls below 8 km/h (5 mph) the message
centre will beep three times and display AIRSUS
ISOLATED.
To cancel crawl mode, release the inhibit switch or
depress the up switch.
