Suspension Kneeling System
The Kneeling System may be fitted with
options specified by the Bodybuilder
but not covered in the following
paragraph. Operators must familiarise
themselves with any instructions issued
by the Bodybuilder.
The Kneeling System deflates and
inflates the suspension air bags on the
front suspension. The system will not
operate if the doors are open, if the
handbrake is not on, or if the vehicle is
moving. Conversely, the system will
prevent the doors from opening if the
vehicle is moving or if raising or
lowering process is operating.
If the handbrake is moved to the OFF
position while the front of the vehicle is
lowered, the suspension will
automatically return to normal ride
height.
1. Kneel Button - Black
Press and hold until lowering
reaches required level.
The button is not operative if:
• The vehicle is moving.
• The handbrake is not ON.
• The system air pressure is too
low.
2. Raise Button - Blue
Press once and the vehicle will
return to normal ride height. The
vehicle will also return to normal
ride height automatically if the
handbrake is released.
3. Full Kneel Button - Black (when
fitted)
Press and hold until the vehicle
has lowered to the required level.
