Driving and Operating 9-45 Locking Rear Axle Vehicles with a locking rear axle can give more traction on snow, mud, ice, sand, or gravel. It works like a standard axle most of the time, but when traction is low, this feature will allow the rear wheel with the most traction to move the vehicle. independently adjust the damping level to provide the optimum vehicle ride. Autoride also interact with the tow/ haul mode that, when activated, will provide additional control of the shock absorbers. This additional control results in better ride and handling characteristics when the vehicle is loaded or towing a trailer. See "Tow/Haul Mode" under Trailer Towing on page 9‑64 for more information. Continuous Damping Control (CDC) This vehicle may have a continuous damping control system called Autoride®. With this feature, improved vehicle ride and handling is provided under a variety of passenger and loading conditions.

The controller then sends signals to each shock absorber to rear of the vehicle to maintain proper vehicle height. The system is activated when the ignition key is turned to ON/RUN and will automatically adjust vehicle height thereafter. The system may exhaust (lower vehicle height) for up to ten minutes after the ignition key has been turned off. You may hear the air compressor operating when the height is being adjusted. If a weight‐distributing hitch is being used, it is recommended to allow the shocks to inflate, thereby leveling the vehicle prior to adjusting the hitch. Automatic Level Control The automatic level control rear suspension is available on light‐duty vehicles and comes as a part of the Continuous Damping Control (CDC) suspension, if equipped. This type of level control is fully automatic and will provide a better leveled riding position as well as better handling under a variety of passenger and loading conditions. An air compressor connected to the rear shocks will raise or lower the
