Before lifting vehicle equipped with air suspension system, turn service to OFF position. Switch is located in jack storage area. Failure to turn off air suspension system may result in unexpected inflation or deflation of air shocks or springs.
On models equipped with Automatic Ride Control (ARC, air suspension), raise and disconnect air lines at shock absorbers. On all models, bounce vehicle front and rear suspension. Measure and record dimension "A" between lower control arm pivot bolt head and ground. See Fig. 1 . Measure and record dimension "B" between lowest point on steering knuckle and ground. Subtract dimension "B" from dimension "A" to obtain ride height. See RIDE HEIGHT SPECIFICATIONS TABLE.
