Extended Modes

Lower Inhibit  Lower inhibit is a reactive mode invoked when the when rate of vehicle lowering is below a predefined threshold for a predefined time during a downward height change. Lower inhibit is normally invoked when the vehicle is lowered onto an obstacle.

Belly-Out  Belly-Out is a pro-active mode invoked when the following conditions are satisfied, vehicle moving and speed is below 20 km/h (12.5 mph). Traction activity is induced on axle pairs for fixed period of time and wheel heights above a predetermined threshold on coinciding axle pairs for the same fixed period of time. Belly-Out is normally invoked under the following condition, vehicle is attempting to move and with low levels of traction and supported by an obstacle.

If the vehicle body is raised, for example by a jack, or grounded in severe off-road conditions, the system may automatically enter Extended Mode. Indicators in the raise/lower switch will flash and the message center will display "SUSPENSION IN EXTENDED MODE".

The suspension can rise automatically to assist in clearing the obstacle. Once extended mode height has been achieved, the driver may request additional lifting if required. This is achieved by pressing up and holding the raise/lower switch for longer than 3 seconds while pressing the brake pedal.

Extended mode is cancelled by pressing down on the raise/lower switch (2) or when the vehicle speed confirms that the body is no longer lifted or grounded.
