Liftgate

Warning

Exhaust gases can enter the vehicle if it is driven with the liftgate or trunk/hatch open, or with any objects that pass through the seal between the body and the trunk/hatch or liftgate. Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. If the vehicle must be driven with the liftgate or trunk/hatch open: . Close all of the windows. . Fully open the air outlets on or under the instrument panel. . Adjust the climate control system to a setting that brings in only outside air and set the fan speed to the highest setting. See “Climate Control Systems” in the Index.

. If the vehicle is equipped with a power liftgate, disable the power liftgate function.

Caution

To avoid damage to the liftgate or liftgate glass, make sure the area above and behind the liftgate is clear before opening it.

Manual Liftgate

To unlock the liftgate, press K on the power door lock switch or press K on the RKE transmitter twice within five seconds. See Remote Keyless Entry (RKE) System Operation 0 7.

To open the liftgate, press the touch pad on the bottom of the liftgate handle and lift up. Use the pull cup to lower and close the liftgate. Do not press the touch pad while closing the liftgate. This will cause the liftgate to be unlatched. If equipped with Keyless Access, the liftgate can be opened when locked if the RKE transmitter is within 1 m (3 ft) of the touch pad. See Remote Keyless Entry (RKE) System Operation 0 7.

The liftgate has an electric latch. If the battery is disconnected or has low voltage, the liftgate will not open. The liftgate will resume operation when the battery is reconnected and charged. Always close the liftgate before driving.

Power Liftgate Operation

Warning

You or others could be injured if caught in the path of the power liftgate. Make sure there is no one in the way of the liftgate as it is opening and closing.

Caution

Driving with an open and unsecured liftgate may result in damage to the power liftgate components.

If equipped, the power liftgate switch is on the driver door. The vehicle must be in P (Park). The taillamps flash when the power liftgate moves. The modes are: . MAX: Opens to maximum height. . 3/4: Opens to a reduced height that can be set from 3/4 to fully open. Use to prevent the liftgate from opening into overhead obstructions such as a garage door or roof-mounted cargo. The liftgate can be manually opened all the way.

. OFF: Opens manually only. To power open or close the liftgate, select MAX or 3/4 mode.

. Pressb twice quickly on the RKE transmitter until the liftgate moves.

. Press8 on the driver door. The driver door must either be unlocked or locked without the security armed.

. Press the touch pad on the bottom of the liftgate after unlocking all doors. If equipped with Keyless Access, a locked vehicle can be opened if the RKE transmitter is within 1 m (3 ft) of the touch pad.

Pressl _ on the bottom of the liftgate next to the pull cup to close.

Press any liftgate button, the touch pad, orb on the RKE transmitter while the liftgate is moving to stop it. Pressing any liftgate button or pressingb twice quickly on the RKE transmitter again restarts the operation in the reverse direction. Pressing the touch pad on the liftgate handle will restart the motion, but only in the opening direction.

Caution

Manually forcing the liftgate to open or close during a power cycle can damage the vehicle. Allow the power cycle to complete.

The power liftgate may be temporarily disabled under extreme low temperatures, or after repeated power cycling over a short period of time. If this occurs, the liftgate can still be operated manually. If the vehicle is shifted out of P (Park) while the power function is in progress, the liftgate will continue to completion. If the vehicle is accelerated before the liftgate has completed moving, the liftgate may stop or reverse direction. Check for Driver

Information Center (DIC) messages and make sure the liftgate is closed and latched before driving.

Falling Liftgate Detection

If the power liftgate automatically closes after a power opening cycle, it indicates that the system is reacting to excess weight on the liftgate or a possible support strut failure. A repetitive chime will sound while the falling liftgate detection feature is operating. Remove any excess weight. If the liftgate continues to automatically close after opening, see your dealer for service before using the power liftgate. Interfering with the power liftgate motion or manually closing the liftgate too quickly after power opening may resemble a support strut failure. This could also activate the falling liftgate detection feature. Allow the liftgate to complete its operation and wait a few seconds before manually closing the liftgate.

Obstacle Detection Features

If the liftgate encounters an obstacle during a power open or close cycle, the liftgate will automatically reverse direction and move a short distance away from the obstacle. After removing the obstruction, the power liftgate operation can be used again. If the liftgate encounters multiple obstacles on the same power cycle, the power function will deactivate. After removing the obstructions, manually close the liftgate which will allow normal power operation functions to resume. If the vehicle is locked while the liftgate is closing, and an obstacle is encountered that prevents the liftgate from completely closing, the horn will sound as an alert that the liftgate did not close.

Setting the 3/4 Mode

To change the position the liftgate stops at when opening: 1. Select MAX or 3/4 mode and power open the liftgate. 2. Stop the liftgate movement at the desired height by pressing any liftgate button. Manually adjust the liftgate position if needed.

3. Press and holdl next to the pull cup on the outside of the liftgate until the turn signals flash and a beep sounds. This indicates the setting has been recorded.

The liftgate cannot be set below a minimum programmable height. If there is no light flash or sound, then the height adjustment may be too low.

Manual Operation

Select OFF to manually operate the liftgate. See “Manual Liftgate” at the beginning of this section.

Caution

Attempting to move the liftgate too quickly and with excessive force may result in damage to the vehicle.

Operate the liftgate manually with a smooth motion and moderate speed. The system includes a feature which limits the manual closing speed to protect the components.

 Hands-Free Operation

If equipped, the liftgate may be operated with a kicking motion under the left side of the rear bumper. The RKE transmitter must be within 1 m (3 ft) of the rear bumper to operate the power liftgate hands-free. The hands-free feature will not work while the liftgate is moving. To stop the liftgate while in motion use one of the liftgate buttons. The hands-free feature can be customized. See Vehicle Personalization 0 124. Choose from the following:

On-Open and Close : The kicking motion is activated to both open and close the liftgate.

On-Open Only : The kicking motion is activated to only open the liftgate.

Off : The feature is disabled.

Kick Zone

To operate, move your foot in a forward kicking motion under the left side of the rear bumper, at the location of the projected logo, then pull it back. Then step back. The kick must come within 14 cm (6 in) of the rear bumper to activate.

Caution

Splashing water may cause the liftgate to open. Keep the RKE transmitter away from the rear bumper detection area or turn the liftgate mode to OFF when cleaning or working near the rear bumper to avoid accidental opening.

. Do not sweep your foot side to side.

. Do not keep your foot under the bumper; the liftgate will not activate.

. Do not touch the liftgate until it has stopped moving.

. This feature may be temporarily disabled under some conditions. If the liftgate does not respond to the kick, open or close the liftgate by another method or start the vehicle. The feature will be re-enabled.

When closing the liftgate using this feature, there will be a short delay. The taillamps will flash and a chime will sound. Step away from the liftgate before it starts moving.

Projected Logo

If equipped with this feature, a vehicle logo will be projected for one minute onto the ground near the rear bumper when an RKE transmitter is detected within approximately 2 m (6 ft). The projected logo may not be visible under brighter daytime conditions.

1. 1 m (3 ft) Hands-Free Operation Detection Zone

2. 2 m (6 ft) Projected Logo Detection Zone

The projected logo shows where the kicking motion is to take place. The projected logo will only be available for this RKE transmitter after it has been out of range for at least 20 seconds. If an RKE transmitter is again detected within approximately 2 m (6 ft) of the liftgate, or another hands-free operation has been detected, the one-minute timer will be reset.

The projected logo will not work under these conditions: . The vehicle battery is low. . The transmission is not in P (Park). . Hands Free Liftgate Control is set to Off in vehicle personalization. See Vehicle Personalization 0 124.

. The power liftgate is turned off.

. The vehicle remains parked for 72 hours or more, with no RKE transmitter use or Keyless Access operation. To re-enable, press any button on the RKE transmitter or open and close a vehicle door.

The projected logo will not work for a single RKE transmitter when a transmitter: . Has been left within approximately 5 m

(15 ft) of the liftgate for several minutes. . Has been left inside the vehicle and all vehicle doors are closed. . Has approached the area outside of the liftgate five times within 10 minutes.

Lens Cleaning

Use a soft, damp cloth to clean the recessed lens.
