STARTING AND DRIVING CAUTION D Do not pump the brake pedal if the hybrid system is not operating. Each push on the pedal uses up your reserved brake fluid pressure. D Even if the power assist is completely lost, the brakes will still work. But you will have to push the pedal hard, much harder than normal. And your braking distance will increase. BRAKE PAD WEAR LIMIT INDICATORS 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. 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. 453
