Shifting into a drivegear while your engine is "racing" (running at high speed) is dangerous. Unless your footis firmly on the brake pedal, your vehicle could move very rapidly. You could lose control andhit people or objects. Don't shift into a drivegear while your engine is racing. Notice: Damage to your transaxle caused by shifting into a drivegear with the engine racingisn't covered by your warranty. AUTOMATIC OVERDRIVE (D): This position is for normal driving. If you need more power for passing, and you're: Going less than 35 mph (55 km/h), push your accelerator pedal about haltway down. Going about 35 mph (55 km/h) or more, push the accelerator all the way down. You'll shift down to the next gear and have more power. Notice: If your vehicle seems to start up rather slowly, or if it seems not to shift gears as you go faster, something may be wrong with a transaxle system sensor. If you drive very far that way, your vehicle can be damaged. So, if this happens, have your vehicle serviced rightaway. Until then, you can use SECOND (2) when you are driving less than 35 mph (55 km/h) and AUTOMATIC OVERDRIVE (D) for higher speeds. Warm-up Shift Your vehicle has a computer controlled transaxle designed to warm up the engine faster when the outside temperature is 35°F (2°C) or colder. You may notice that the transaxle will shift at a higher vehicle speed until the engine is warmed up. This is a normal condition designed to provide heat to the passenger compartment and defrost the windows more quickly. See Climate Control System on page 3-24 for more information. 2-35
