Leaving children in a vehicle with an ignition key or Remote Keyless Entry (RKE) transmitter is dangerous and children or others could be seriously injured or killed. They could operate the power window or other controls or make the vehicle move. The windows will function with the key in the ignition or with the RKE transmitter in the vehicle, and children or others could be caught in the path of a closing window. Do not leave children in a vehicle with the ignition key or an RKE transmitter.

This could be caused by heavy items hanging from the key ring, or by large or long items attached to the key ring that could be contacted by the driver or steering wheel. If the ignition moves out of the RUN position, the engine will shut off, braking and steering power assist may be impacted, and airbags may not deploy. To reduce the risk of unintentional rotation of the ignition key, do not change the way the ignition key and Remote Keyless Entry (RKE) transmitter, if equipped, are connected to the provided key rings.

The combination and size of the rings that came with your keys were specifically selected for your vehicle. The rings are connected to the key like two links of a chain to reduce the risk of unintentionally moving the key out of the RUN position. Do not add any additional items to the ring attached to the ignition key. Attach additional items only to the second ring, and limit added items to a few essential keys or small, light items no larger than an RKE transmitter.

Vehicle

For the Tahoe Police and Tahoe

Special Service Packages, see the

Tahoe Police and Tahoe and

Supplement.

Follow these procedures to program

up to eight keys to the vehicle.

Programming with Two

Recognized Keys

To program a new key:

1. Insert the original, already programmed key in the ignition and turn the ignition on without starting the engine.

2. Turn the ignition off and remove the key.

3. Quickly, within five seconds, insert the second original already programmed key in the ignition and turn the ignition on without starting the engine.

4. Turn the ignition off and remove the key.

5. Insert the new key to be programmed, and within five seconds, turn the ignition on without starting the engine.

The security light will turn off once the key has been programmed.

6. Repeat Steps 1–5 if additional keys are to be programmed.

If a key is lost or damaged, see your dealer to have a new key made.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/15/19

Programming without Two Recognized Keys

Program a new key to the vehicle when a recognized key is not available. Canadian regulations require that Canadian owners see their dealer.

If two currently recognized keys are not available, follow this procedure to program the first key.

This procedure will take approximately 30 minutes to complete for the first key. The vehicle must be off and all of the keys must be with you.

1. Insert the new vehicle key into the ignition.

2. Turn the ignition on without starting the engine. The security light will come on.

3. Wait 10 minutes until the security light turns off.

4. Turn the ignition off.

5. Repeat Steps 2–4 two more times. After the third time, turn the ignition on; the key is

learned and all previously known keys will no longer work with the vehicle.

6. To learn the second key, turn the ignition off and insert the second key to be learned and turn the ignition on without starting the engine.

After two keys are learned, the remaining keys can be learned by following the procedure in “Programming with Two Recognized Keys (Key Vehicles Only).”

See your dealer if a replacement key or additional key is needed.

programmed through your dealer. The vehicle can be reprogrammed so that lost or stolen transmitters no longer work. Each vehicle can have up to eight transmitters matched to it.

Programming with Recognized Transmitters

A new transmitter can be programmed to the vehicle when there are two recognized transmitters.

To program, the vehicle must be off and all transmitters, both currently recognized and new, must be with you.

1. Remove the key from the recognized transmitter.

2. Place the two recognized transmitters in the cupholder or on the passenger seat.

3. Insert the vehicle key into the key lock cylinder on the driver door handle. Then turn the key counterclockwise, to the unlock position, five times within 10 seconds.

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.

Warning (Continued)

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.

See Engine Exhaust 0 215.

Caution

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

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 overhead console. The vehicle must be in P (Park).

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 opened manually all the way.

OFF : Opens manually only.

To power open or close the liftgate, select MAX or 3/4 mode and then:

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. Remove any excess weight. A repetitive chime will sound while the falling liftgate detection feature is operating. If the liftgate continues to automatically close after opening, see your dealer for service before using the power liftgate.
