•
•
To operate, kick your foot straight up in one swift

motion under the center of the rear bumper, then

pull it back. There are two antennas located in the

rear bumper fascia that must be triggered for the

system to detect a kick. During the kick, your foot

and shin must come within 6.5 inches (16.5 cm) of

the rear fascia for both antennas to be triggered

and detect the kick.

Speed of kick should be 1 second or less.
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).

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

• 2 m (6 ft) Projected Logo Detection Zone

The projected logo shows where the kicking motion is

to take place.
Page 3
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 the following

conditions:

• The vehicle battery is low.

• The transmission is not in P (Park).

• Hands Free Liftgate Operation is set to OFF in

vehicle personalization. See Vehicle

Personalization.

• 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.

Tips to Avoid to Ensure Best Operation

• Do NOT sweep your foot from side to side.

• Do NOT keep your foot under the bumper.

• Do NOT touch the liftgate until it stops moving.

Caution: The liftgate may open or close if: cleaning or

working near the rear bumper, splashing water,

stepping into the liftgate opening, etc. To avoid this,

keep the RKE fob away from the rear bumper detection

area or turn the liftgate mode switch to Off.

Note: If a customer of a 2015/2016 Chevrolet Tahoe/

Suburban has a concern of the hands free liftgate

feature being too sensitive or activates too easily, see

the latest version of PIT5531 for updated calibrations.
