304 STARTING AND OPERATING MANUAL TRANSAXLE - RECOMMENDED SHIFT SPEEDS To use your manual transaxle for optimal fuel economy, it should be upshifted as listed in Table 1. Table 1 - Manual Transaxle Normal Acceleration And Cruise Shift Speeds In mph (km/h) Engine 2.4L Turbo 2.4L NonTurbo Mode Acceleration Cruise Acceleration Cruise 1 to 2 15 (24) 15 (24) 15 (24) 15 (24) 2 to 3 25 (40) 25 (40) 25 (40) 25 (40) 3 to 4 40 (65) 42 (68) 40 (65) 42 (68) 4 to 5 45 (72) 45 (72) 45 (72) 45 (72) Table 2 - Manual Transaxle Maximum Performance Shift Speeds In mph (km/h) Engine 2.4L 1 to 2 30 (48) 2 to 3 60 (97) 3 to 4 85 (136) 4 to 5 115 (185) If you exceed these speeds, you may notice the engine cut in and out. This is caused by an electronic limiter in the engine computer. The engine will run normally when you reduce engine speed. Downshifting Proper downshifting will improve fuel economy and prolong engine life. For improved performance, your manual transaxle may be upshifted up to the maximum speeds listed in Table 2 (within legal speed limits). CAUTION! If you skip a gear while downshifting or downshift at too high an engine speed, you could damage the engine, transmission, or clutch.
