WARNING:

The evaporative emissions system contains fuel vapor and condensed 
fuel vapor. Although not present in large quantities, it still presents the 
danger of explosion or fire. Disconnect battery ground cable from battery 
to minimize the possibility of an electrical spark occurring, possibly 
causing a fire or explosion if fuel vapor or liquid fuel are present in the 
area. Failure to follow these instructions may result in personal injury. Do 
not smoke or carry lighted tobacco or open flame of any type when 
working on or near any fuel related component. Highly flammable 
mixtures are always present and may be ignited, resulting in possible 
personal injury. Failure to follow these instructions may result in personal 
injury.

WARNING:

On Blackwood and Navigator models, 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, located below the glove box in the lower right side of 
the passenger foot well. Failure to do so may result in shifting of the 
vehicle during these operations. Failure to follow these instructions may 
result in personal injury.
