{CAUTION: Shifting into a drive gear while your engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while your engine is running at high speed. Notice: Shifting out of PARK (P) or NEUTRAL (N) while the engine is running at high speed may damage the transaxle. The repairs would not be covered by your warranty. Be sure the engine is not running at high speeds when shifting your vehicle. AUTOMATIC OVERDRIVE (D4): This position is for normal driving. When operating your vehicle in severe cold conditions, the transaxle may be prevented from shifting into D4 gear until the transaxle fluid has warmed up to it's operational temperature. Notice: If your vehicle seems to start up rather slowly or not shift gears when you go faster, and you continue to drive your vehicle that way, you could 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. 113
