WARNING: Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or property damage. The occurrence of a traction
control event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
AIR SUSPENSION (IF EQUIPPED)
Note: The vehicle must not be operated without air in the suspension
springs. Operating the vehicle without air in the air suspension springs
will damage the suspension, degrade ride performance and may cause
property damage.
The suspension system automatically adjusts to different loads to
maintain a constant frame height. The system allows for ease of vehicle
loading and provides improved vehicle ride and increased driver comfort.
Air suspension dump switch (if equipped)
The system is controlled by a switch
located in the overhead switch pack.
The switch will operate only when
the ignition is in the accessory or on
positions and the air tanks have
sufficient pressure to fill the air
springs. When the ignition is turned
off, the suspension will remain in
whatever state it was last set.
Note: The suspension will dump air when the ignition is in the accessory
or on position, but will only fill when the ignition is in the on position.
When the upper portion of the switch is pressed air supplied to the air
spring is exhausted, lowering the frame for loading. Pressing the lower
portion of the switch causes air to fill the air springs so the vehicle will
remain at normal ride height.
