'00 AVALON U (L/O 9908) Iridium- tipped spark plugs Brake system This brake system has two independent hydraulic circuits. If either circuit should fail, the other will still work. However, the pedal will be harder to press, and your stopping distance will be longer. Also, the brake system warning light may come on. CAUTION D Do not pump the brake pedal if the engine stalls. Each push on the pedal uses up your reserved vacuum. CAUTION Do not drive your vehicle with only a single brake system. Have your brakes fixed immediately. BRAKE BOOSTER The brake booster uses engine vacuum to power- assist the brakes. If the engine should quit while you are driving, you can bring the vehicle to a stop with normal pedal pressure. There is enough reserved vacuum for one or two stops-but no more! 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 be longer. Your engine is fitted with iridium- tipped spark plugs. NOTICE Use only iridium- tipped spark plugs and do not adjust gaps for your engine performance and smooth driveability. 234
