WARNING:

The electrical power to the air suspension system must be shut off
prior to hoisting, jacking or towing an air suspension vehicle. This
can be accomplished by turning off the air suspension switch in the
RH kick panel area. Failure to do so may result in unexpected
inflation or deflation of the air springs which may result in shifting of
the vehicle during these operations.
