Driving ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED) Your vehicle may be equipped with a full-time All Wheel Drive (AWD) system. The AWD system is an active system, meaning it not only responds to wheel slip between the front and rear axles but also has the ability to anticipate wheel slip and transfer torque to the rear wheels before slip occurs. The AWD system is active all the time and requires no input from the operator. All components of the AWD system are sealed for life and require no maintenance. If your vehicle is equipped with AWD, a spare tire of a different size other than the tire provided should never be used. A dissimilar spare tire size (other than the spare tire provided) or major dissimilar tire sizes between the front and rear axles could cause the AWD system to stop functioning and default to front wheel drive. Note: Your AWD vehicle is not intended for off-road use. The AWD feature gives your vehicle some limited off-road capabilities in which driving surfaces are relatively level, obstruction-free and otherwise similar to normal on-road driving conditions. Operating your vehicle under other than those conditions could subject the vehicle to excessive stress which might result in damage which is not covered under your warranty. Driving on slippery surfaces with AWD vehicles AWD vehicles are specially equipped for driving on sand, snow, mud and rough roads and have operating characteristics that are somewhat different from conventional vehicles, both on and off the highway. When driving at slow speeds off-highway under high outside temperatures, use L (Low) gear when possible. L (Low) gear operation will maximize the engine and transmission cooling capability. Under severe operating conditions, the A/C may cycle on and off to protect overheating of the engine. Basic operating principles • Drive slower in strong crosswinds which can affect the normal steering characteristics of your vehicle. • Be extremely careful when driving on pavement made slippery by loose sand, water, gravel, snow or ice. If your vehicle goes off the edge of the pavement • If your vehicle goes off the edge of the pavement, slow down, but avoid severe brake application, ease the vehicle back onto the 221 2009 Sable (mgo) Owners Guide, 2nd Printing USA (fus)
