Notice: When the compact spare is installed, don't take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. All-Wheel Drive After installing a compact spare tire on a vehicle with all-wheel drive you will need to drive with light to moderate acceleration, for 10 seconds, in a straight line. This action will allow the vehicle to detect the compact spare tire and disable the all-wheel drive system. The AWD DISABLE message will come on indicating that the all-wheel drive system is off. You may detect a slight pull during this time, but this is normal. Notice: You may damage your vehicle's all-wheel drive system if your vehicles driven for an i extended period with a compact spare tire installed and the all-wheel drive system in operation. See "All-Wheel Drive System'' and "AWD Disable Warning Message" in the Index for more information. Don't use your compact spare on other vehicles. And don't mix your compact spare tire or wheel with other wheels or tires. They won't fit. Keep your spare tire and its wheel together. Notice; Tire chains won't fit your compact spare. Using them can damage your vehicle and can damage the chains too. Don't use tire chains on your compact spare. 5-86
