r If your vehicle seems tostart 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 right away. Until then, you can use 2 (Second Gear) when vou are driving less than35 mDh i56 km/h) a n z a (0 higher speeds. D (Third Gear): Thisislike , but you never go into Overdrive. Here are some times you might choose D instead ofm: When driving on hilly, winding roads. When towing a trailer, so there is less shifting between gears. When going down a steep hill. 2 (Second Gear): This position gives you more power but lower fuel economy. You can use 2 on hills. It can help control your speed asyou go down steep mountain roads, but then you would also want to use your brakes off and on. Don't drive in 2 (Second Gear) for more than 5 miles (8 km), or at speeds over 55 mph (88 km/h), or you can damage yourtransaxle. Use or D as much as possible. Don't shift into 2 unless you are going slower than65 mph (105 km/h), or you can damage your engine. I 65 m m m
