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

Movement between certain positions requires pushing the shift lever toward the passenger side while shifting. This prevents you from changing positions unexpectedly by blocking the straight movement of the shift lever while the vehicle is moving.

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 .

Ensure that 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 apply your regular brakes before you can shift from PARK (P) when the key is in ON. If you cannot shift out of PARK (P) while holding the brake pedal down, see Shifting Out of Park .

REVERSE (R): Use this gear to back up. When shifting from NEUTRAL (N) to REVERSE (R), you need to apply the regular brake and push the shift lever down and toward the passenger side of the vehicle and then forward.

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 while 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.

AUTOMATIC OVERDRIVE (D4): This position is for normal driving.

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.

FIRST (1): This position gives you even more power but lower fuel economy than SECOND (2). You can use it 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.

If there is a malfunction with the automatic transaxle, the malfunction indicator lamp (MIL) or the HOLD indicator light will turn on or flash. See Malfunction Indicator Lamp or Hold Mode Light .

Have your vehicle fixed as soon as possible.

Hold Mode

If your vehicle's transaxle has hold mode, you can select this mode to drive with some characteristics of a manual transaxle. With hold mode turned on, the automatic transaxle will stay in a specific gear range.


Object Number: 1252646  Size: B3

Press the HOLD button on the shift lever console to turn on hold mode. Press the button again to turn off hold mode, and return to normal automatic transaxle operation.

While on, the HOLD indicator light on the secondary information center will light up. See Hold Mode Light .

When hold mode is activated, the transaxle is fixed in the gear selected.

Hold Mode Features

Winter Function

Select hold mode while in AUTOMATIC OVERDRIVE (D4) to help the vehicle maintain traction on slippery road surfaces, such as snow, mud, or ice.

Manually Controlling Shift

Select hold mode to use your automatic transaxle like a three-speed manual transaxle.
