Break-in period S When driving off-road or in rugged terrain, do not drive at excessive speeds, jump, strike objects, etc. This may cause loss of control or vehicle rollover. You are also risking expensive damage to your vehicle's suspension and chassis. Drive gently and avoid high speeds. Your vehicle does not need an elaborate break-in. But following a few simple tips for the first 1600 km (1000 miles) can add to the future economy and long life of your vehicle: S Do not drive over 88 km/h (55 mph). S Run the engine at moderate speed between 2000 and 4000 rpm. S Avoid full-throttle starts. S Try to avoid hard stops during the first 300 km (200 miles). S Do not drive slowly with the manual transmission in a high gear. S Do not drive for a long time at any single speed, either fast or slow. S Do not tow a trailer during the first 800 km (500 miles). Fuel Selecting the proper fuel is essential for satisfactory engine performance. Engine damage caused by use of improper fuels is not covered under Toyota's new vehicle warranty. FUEL TYPE Use only unleaded gasoline. To help prevent gas station mixups, vehicles designed for use with unleaded gasoline have a new smaller fuel tank opening. The special nozzle on pumps with unleaded fuel will fit it, but the larger standard nozzle on pumps with leaded gas will not. NOTICE Do not use leaded gasoline. Use of leaded gasoline will cause the three-way catalytic converter to lose its effectiveness and the emission control system to function improperly. Also, this can increase maintenance costs. OCTANE NUMBER Select Research Octane Number 91 (Octane Rating 87) or higher. Use of unleaded fuel with an octane number or rating lower than stated above will cause persistent heavy knocking. If severe, this will lead to engine damage. 98
