Driving The air suspension shut-off switch is located behind an access panel underneath the passenger side instrument panel. On vehicles equipped with Air Suspension, turn OFF the Air Suspension switch prior to jacking, hoisting or towing your vehicle. OFF Normal vehicle operation does not require any action by the driver. TRACTION-LOK AXLE (IF EQUIPPED) This axle provides added traction on slippery surfaces, particularly when one wheel is on a poor traction surface. Under normal conditions, the Traction-Lok axle functions like a standard rear axle. Extended use of other than the manufacturer's specified size tires on a Traction-Lok rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. To avoid injury, never run the engine with one wheel off the ground, such as when changing a tire. AIR SUSPENSION SWITCH INTERRUPTEUR DE LA SUSPENSION PNEUMATIQUE 103
