Cadillac 2009 Magnetic Ride Control, Road Sensing Suspension, Locking Rear Axle, Steering

Magnetic Ride Control™

The vehicle may have the MagneRide control system. MagneRide constantly checks speed, wheel position, lift/dive and steering of the vehicle. The damping force for each shock absorber and adjustment level is chosen for the best ride and handling.

MagneRide also works with the tow/haul switch that, when engaged, will provide more firmness from the shock absorbers. This added control gives better

ride and handling when carrying heavy loads or towing a trailer. See Tow/Haul Mode on page 2-39for more information.

Road Sensing Suspension

The Road Sensing Suspension (RSS) feature provides superior vehicle ride and handling under a variety of passenger and loading conditions.

The system is fully automatic and uses a computer controller to continuously monitor vehicle speed, wheel to body position, lift/dive and steering position of the vehicle. The controller then sends signals to each shock absorber to independently adjust the damping level to provide the optimum vehicle ride.

RSS also interacts with the tow/haul mode that, when engaged, 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 Towing a Trailer on page 5-40.

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.

All-Wheel Drive (AWD) System

With this feature, engine power is sent to all four wheels at all times. This is like four-wheel drive, but there is no separate lever or switch to engage or disengage the front axle. It is fully automatic, and adjusts itself as needed for road conditions.

Steering

Power Steering

If power steering assist is lost because the engine stops or the system is not functioning, the vehicle can be steered but it will take more effort.
