STARTING AND DRIVING Drum-in-disc type parking brake system Your vehicle has a drum-in-disc type parking brake system. This type of brake system needs bedding-down of the brake shoes periodically or whenever the parking brake shoes and/or drums are replaced. Have your Lexus dealer perform the bedding-down. BRAKE PAD WEAR LIMIT INDICATORS 31X020b The brake pad wear limit indicators on your disc brakes give a warning noise when the brake pads are worn to the extent that replacement is required. If you hear a squealing or scraping noise while driving, have the brake pads checked and replaced by your Lexus dealer as soon as possible. Expensive rotor damage can result if the pads are not replaced when needed. TYPES OF TIRES Determine what kind of tires your vehicle is originally equipped with. 1. Summer tires Summer tires are high-speed capability tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered or icy roads, we recommend using snow tires. If installing snow tires, be sure to replace all four tires. 393
