If your vehicle is equipped with an automatic transaxle, the shift lever is located on the console between the seats.


Object Number: 1509574  Size: A2

There are several different positions for the automatic transaxle.

PARK (P): This position locks your front wheels. It is the best position to use when you start your engine because your vehicle cannot move easily.

Caution: It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll.

Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park . If you are pulling a trailer, see Towing a Trailer .

Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transaxle shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever-- push the shift lever all the way into PARK (P) and also release the shift lever button as you maintain brake application. Then move the shift lever into the gear you wish. Press the shift lever button before moving the shift lever. See Shifting Out of Park .

REVERSE (R): Use this gear to back up.

Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transaxle. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped.

To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transaxle, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow .

NEUTRAL (N):  In this position, your engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed.

Caution: Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the 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.

Notice: Shifting to a drive gear from NEUTRAL (N) while the vehicle is moving could damage the transaxle. Make sure the vehicle is stopped before shifting from NEUTRAL (N) into a drive gear.

AUTOMATIC OVERDRIVE (D): This position is for normal driving with the automatic transaxle. If you need more power for passing, and you are:

    • Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down.
    • Going about 35 mph (55 km/h), push your accelerator all the way down.
INTERMEDIATE (I): This position is also used for normal driving. However, it offers braking from the engine for slight downgrades where the vehicle would otherwise accelerate due to steepness of grade. If repetitive shifts occur between third and fourth gears on steep uphills, this position can be used to prevent repetitive shifting. Fuel economy will be lower than AUTOMATIC OVERDRIVE (D). Here are some times you might choose INTERMEDIATE (I) instead of AUTOMATIC OVERDRIVE (D):

    • When driving on hilly, winding roads.
    • When towing a trailer, so there is less shifting between gears.
LOW (L): This position gives you even more power but lower fuel economy than INTERMEDIATE (I). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in LOW (L), the transaxle will not shift into LOW (L) 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.
