Operation CHARM: Car repair manuals for everyone.

Suspension: Service Precautions

On models with electronic level control system, when diagnosis or repair requires raising the vehicle on a hoist, it is important that the rear axle remains in normal trim height position at all times, therefore, the hoist should support the rear wheels or axle housing. When a frame contact hoist is used, two additional jack stands should be used to support the rear axle or control arms in the normal trim height position.
