AUTOMATIC OVERDRIVE (D4): This position is for normal driving. When operating your vehicle in severe cold conditions, the transmission may be prevented from shifting into D4 gear until the transmission fluid has warmed up to it's operational temperature. Notice: Driving your vehicle if you notice that it is moving slowly or not shifting gears as you increase speed may damage the transaxle. Have your vehicle serviced right away. You can drive in SECOND (2) when you are driving less than 35 mph (55 km/h) and AUTOMATIC OVERDRIVE (D4) for higher speeds until then. SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. Notice: Do not drive in SECOND (2) at speeds over 65 mph (105 km/h), or you can damage the transaxle. Use AUTOMATIC OVERDRIVE (D4) as much as possible. Do not shift into SECOND (2) unless you are going slower than 65 mph (105 km/h) or you can damage your engine. FIRST (1): This position gives you even more power but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1), the transaxle will not shift into first gear until the vehicle is going slowly enough. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transaxle. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes, or parking brake to hold the vehicle in place. If there is a malfunction with the automatic transaxle, the malfunction indicator lamp (MIL) or the HOLD indicator light will turn on or flash. See Malfunction Indicator Lamp on page 3-34 or Hold Mode Light on page 3-34. Have your vehicle fixed as soon as possible. 2-23
