11-30 Maintenance and service Parking brake stroke Tires and wheels ¢ Types of tires You should be familiar with type of tires present on your vehicle. The factory-fitted tires are all-season tires except for the 17-inch tires that are optional on the Aero (those are summer tires). q All season tires All season tires are designed to provide an adequate measure of traction, handling and braking performance in year-round driving including snowy and icy road conditions. However all season tires do not offer as much traction performance as winter (snow) tires in heavy or loose snow or on icy roads. All season tires are identified by "ALL SEASON" and/or "M+S" (Mud & Snow) on the tire sidewall. q Summer tires Summer tires are high-speed capability tires best suited for highway driving under dry conditions. Summer tires are inadequate for driving on slippery roads such as on snow-covered or icy roads. If you drive your vehicle on snow-covered or icy roads, we strongly recommend the use of winter (snow) tires. When installing winter tires, be sure to replace all four tires. q Winter (snow) tires Winter tires are best suited for driving on snow-covered and icy roads. However winter tires do not perform as well as summer tires and all season tires on roads other than snow-covered and icy roads. ¢ Tire inspection Check on a daily basis that the tires are free from serious damage, nails, and stones. At the same time, check the tires for abnormal wear. Contact your Saab dealer immediately if you find any problem.

When the parking brake is properly adjusted, braking power is fully applied by pulling the lever up seven to eight notches gently but firmly (approximately 44 lbs [196 N, 20 kg]). If the parking brake lever stroke is not within the specified range, have the brake system checked and adjusted at your Saab dealer. NOTE — When the wheels and tires strike curbs or are subjected to harsh treatment as when the vehicle is driven on a rough surface, they can suffer damage that cannot be seen with the naked eye. This type of damage does not become evident until time has passed. Try not to drive over curbs, potholes or on other rough surfaces. If doing so is unavoidable, keep the vehicle's speed down to a walking pace or less, and approach the curbs as squarely as possible. Also, make sure the tires are not
