174 STARTING AND OPERATING Autostick General Information • The transaxle will automatically upshift from first to second gear and from second to third gear when engine speed reaches about 6300 RPM. • Downshifts from third to second gear above 66 mph (106 km/h) and from second to first gear above 37 mph (60 km/h) will be ignored. • You can start out in first, second, or third gear. Shifting into fourth gear can occur only after vehicle speed reaches 15 mph (24 km/h). • The transaxle will automatically downshift to first gear when coming to a stop. • Starting out in third gear is helpful in snowy or icy conditions. • While in the Autostick mode, Speed Control will only function in third or fourth gear. Downshifting out of third gear turns off speed control. • If the system detects powertrain overheating, the transaxle will revert to the automatic shift mode and remain in that mode until the powertrain cools off. • If the system detects a problem it will disable the Autostick mode and the transaxle will return to the automatic mode until the problem is corrected. FUEL REQUIREMENTS Your vehicle is designed to meet all emission regulations and provide excellent fuel economy when using high quality regular unleaded gasoline with an octane rating of 87. The use of premium gasoline is not recommended. The use of premium gasoline will provide no benefit over high quality regular gasolines, and in some circumstances, may result in poorer performance. Spark Knock Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required.
