Rear Suspension Dump Switch
Notice: Do not operate the vehicle over uneven ground such as ramps, speed bumps, curbs, etc., with the air springs deflated. Doing this may lead to air bag separation from the piston, preventing the suspension air springs from reinflating.
Note: The vehicle must be moving less than 5 mph (8 km/h) before the rear suspension will deflate.
The rear suspension dump switch is a two-position guarded rocker switch. See Fig.. It allows the air in the vehicle rear air suspension to be quickly exhausted, lowering the rear of the vehicle.
To lower the rear of the vehicle quickly, press the upper half of the rocker switch momentarily; the light-emitting diode (LED) indicator at the top of the dump switch blinks. When conditions are met for the suspension to be dumped the vehicle is moving at a speed less than 5 mph (8 km/h) the LED indicator illuminates steady. To raise the suspension to its normal height, press the upper half of the rocker switch again or drive the vehicle at a speed greater than 5 mph (8 km/h).
