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 hand brake, 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 illuminated. The message centre in the instrument binnacle will beep three times and display EAS MANUAL . 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 EAS MANUAL .
To cancel crawl mode, release the inhibit switch or depress the up switch.
High ride height
This position is used to improve approach and departure angles and when wading. When at standard ride height, pressing the up switch will select high ride height provided the road speed is below 56 km/h (35 mph). The high ride height indicator will flash during the height change. When the change is complete the indicator will remain constantly illuminated, and standard ride height indicator will be extinguished. The indicator in the instrument pack will also be illuminated. It speed exceeds 56 km/h (35 mph) , the vehicle will return to standard profile.
Extended ride height
This position is achieved if chassis is grounded leaving wheel or wheels unsupported. Initial ECU reaction is to lower (deflate) affected springs. After a timed period the ECU detects no height change, it therefore reinflates springs to extended profile in an attempt to regain traction. The position will be held for 10 minutes, after which time the vehicle will automatically return to standard ride height.
Pressing the down switch will lower vehicle 20 mm to high profile.
If vehicle speed exceeds 56 km/h (35 mph) the vehicle will immediately lower to standard ride height. This speed could be achieved, for example, by wheel spin.
VEHICLE TRANSPORTATION
New vehicles are transported from the factory with the EAS system electronically 'frozen' in access mode. When road speed exceeds 40 km/h (25 mph), the vehicle will rise to low ride height. It will return to access mode it speed falls below 38.4 km/h (24 mph). This condition is cancelled at pre-delivery inspection, by entering the appropriate command via Testbook.
Vehicle transportation/recovery
CAUTION: When an air suspension vehicle is secured to a transporter using the chassis lashing eyes, there is a possibility due to air leakage, self levelling or operation of ride height controls that the tension of the securing straps will be lost. To prevent this the ride height should be set to access mode before securing to transporter.
If the engine cannot be run and the vehicle is not in access mode, the vehicle can be transported, but it must be secured to the transporter by the roadwheels, not the chassis.
