The shift lever for the automatic transmission is on the steering column.


Object Number: 811723  Size: B1

The ignition positions are displayed on the instrument panel cluster and will indicate the gear the vehicle is in.

Maximum engine speed is limited on automatic transaxle vehicles when they are in PARK (P) or NEUTRAL (N) to protect driveline components from improper operation.

There are several different positions for the shift lever.

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 .

PARK (P)This position locks the vehicle's front wheels. It is the best position to use when the engine is started because the vehicle cannot move easily.

Make sure the shift lever is fully in PARK (P) before starting the engine. The vehicle has an automatic transaxle shift lock control system. The regular brakes must be fully applied before shifting from PARK (P) when the ignition is in RUN. If the vehicle cannot be shifted out of PARK  (P), increase pressure on the shift lever by pushing it all the way into PARK  (P) while keeping the brake pedal pushed down. Then move the shift lever out of PARK  (P). See Shifting Out of Park .

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.

REVERSE (R)Use this gear to back up.

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

NEUTRAL (N)In this position, the engine does not connect with the wheels. To restart when the vehicle is already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when the 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: 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 (D) for higher speeds until then.

AUTOMATIC OVERDRIVE (Overdrive)This position is for normal driving. If more power is needed for passing, and the vehicle is:

    • Going less than 35 mph (55 km/h), push the accelerator pedal about halfway down.
    • Going about 35 mph (55 km/h) or more, push the accelerator pedal all the way down.

By doing this the vehicle will shift down to the next gear and have more power.

THIRD (3)This position is also used for normal driving, but it offers more power and lower fuel economy than AUTOMATIC OVERDRIVE (Overdrive).

Here are some times you might choose THIRD (3) instead of AUTOMATIC OVERDRIVE (Overdrive):

    • When driving on hilly, winding roads.
    • When towing a trailer, so there is less shifting between gears.
    • When going down a steep hill.
    • When driving in no-highway scenarios such as city streets.

Notice: Driving in SECOND (2) for more than 25 miles (40 km) or at speeds over 55 mph (90 km/h) may damage the transaxle. Also, shifting into SECOND (2) at speeds above 65 mph (105 km/h) can cause damage. Drive in THIRD (3) or AUTOMATIC OVERDRIVE (D) instead of SECOND (2).

SECOND (2)This position gives the vehicle more power than THIRD (3) but lower fuel economy than THIRD (3). You can use SECOND (2) on hills. It can help control the speed going down steep mountain roads, but then you would also want to use your brakes off and on.

FIRST (1)This position gives the vehicle even more power but lower fuel economy than SECOND (2). It can be used 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.
