'98 Tacoma (U) Break-in period D When driving off-road or in rugged terrain, do not drive at excessive speeds, jump the vehicle, or 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: Fuel FUEL TYPE Your new vehicle must use only unleaded gasoline. To help prevent gas station mixups, your Toyota has 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. At a minimum, the gasoline you use should meet specifications of ASTM D4814 in the U.S.A. and CGSB 3.5- M93 in Canada. D Do not drive over 88 km/h (55 mph). D Run the engine at moderate speed between 2000 and 4000 rpm. D Avoid full-throttle starts. D Try to avoid hard stops during the first 300 km (200 miles). D Do not drive slowly with the manual transmission in a high gear. NOTICE Do not use leaded gasoline. Use of leaded gasoline will cause the threeway catalytic converter to lose its effectiveness and the emission control system to function improperly. Also, this can increase maintenance costs. D Do not drive for a long time at any single speed, either fast or slow. D Do not tow a trailer during the first 800 km (500 miles). Four-wheel drive models wheeling hubs only- with free- For the first 500 km (300 miles): We recommend that you use high range, two-wheel drive, with both free-wheeling hubs engaged. For information on the four-wheel drive system and the front hubs, see "Four-wheel drive system" in Chapter 1- 6. 138
