Power Liftgate Operation

~4min read

Notice: If you open the liftgate without checking for overhead obstructions such as a garage door, you could damage the liftgate or the liftgate glass.
Always check to make sure the area above and behind the liftgate is clear before opening it.

Vehicles with an automatic

Vehicles with an automatic transmission must be in P (Park) and a manual transmission must be in Neutral to operate the power liftgate. The taillamps flash when the power liftgate moves.

Turn the selector switch to choose one of three modes:

MAX: The liftgate power opens to the full open height.

3/4: The liftgate power opens to a reduced open height that can be set in a range of approximately ¾ open to full open. Use this setting to prevent the liftgate from opening into overhead obstructions such as a garage door or roof mounted cargo during power operation.

The liftgate can still be opened fully manually.

OFF: The liftgate only operates manually in this position.

Manual operation of a liftgate that also has power operation requires more effort than a standard manual liftgate.

In either the MAX or the ¾ mode, the liftgate can be power opened and closed by:

- Pressing and holding the power liftgate button Keyless Entry (RKE) transmitter on the Remote Keyless Entry (RKE) transmitter until the liftgate starts moving.

See Remote Keyless Entry (RKE) System Operation (Keyless Access) or Remote Keyless Entry (RKE) System Operation (Key Access).

- Pressing the power liftgate button in the center of the mode selector switch on the driver door, with the driver door unlocked.

- Pressing the touch pad on the liftgate outside handle, with all doors unlocked, to open the liftgate.

- Pressing and releasing the

- Pressing and releasing the power liftgate button on the liftgate adjacent to the latch to close the liftgate.

Pressing any button that operates the power liftgate, or the touch pad while the liftgate is moving, stops it.

Pressing the button or RKE again reverses the direction. There is a minimum that the power liftgate must already be open for the system to hold it open. If movement is stopped below that minimum, the liftgate closes.

Do not force the liftgate open or closed during a power cycle.

The power liftgate may be temporarily disabled under extreme temperatures or low battery conditions. If this occurs, the liftgate can still be operated manually.

If the transmission is shifted out of P (Park) while the power function is in progress, the liftgate power function will continue to completion.

If the transmission is shifted out of P (Park) and accelerate before the power liftgate latch is closed, the liftgate may reverse to the open position. Cargo could fall out of the vehicle. Close and latch the power liftgate before driving.

If the liftgate is powered open and the liftgate support struts have lost pressure, the turn signals will flash and a chime will sound. The liftgate will stay open, and then slowly close. See your dealer for service before using the liftgate.
