Turn Transport Mode Off Before New Vehicle Delivery

Transport Mode is intended for use when shipping new GM models over long distances from the assembly plant. When enabled, It reduces the parasitic electrical load on the battery when the vehicle is parked, which extends the battery stand time up to 70 days without the battery going dead.

Transport Mode is available on 2012-2020 Sonic; 2013-2021 Encore, Spark, Trax; 2014-2020 Impala; 2015-2021 Escalade, Colorado, Silverado, Tahoe, Suburban, Canyon, Sierra, Yukon; 2016-2020 CT6; 2016-2021 Envision, Camaro, Malibu; 2017-2021 XT5, Bolt EV, Acadia; 2018-2021 Equinox, Terrain; 2019-2020 Regal TourX; 2019-2021 XT4, Blazer; 2020-2021 Encore GX, CT4, CT5, XT6, Corvette; and 2021 Trailblazer models.

If Transport Mode is not turned off before vehicle delivery on new GM models, a Transport Mode On message may be displayed on the Driver Information Center and/or the red battery light may be flashing. (Fig. 18)

Disabled Systems

24 hours after Transport Mode is turned on, with the vehicle off, the key must be used to enter the vehicle, as the following functions will be disabled: Passive Entry, Remote Keyless Entry, Content Theft. On 2016-2021 Escalade, Tahoe, Suburban and Yukon models, the Remote Keyless Entry function remains enabled during Transport Mode, allowing entry without a key. Exit lighting timers function but are reduced.

For new vehicles equipped with Passive Entry/Passive Start (PEPS) that have Transport Mode on, the key fob will operate to enable use of the Engine Start/Stop button, as long as the key fob is inside the vehicle.

The Passive Entry and Remote Keyless Entry functions are restored with the ignition in Run.


Entering a Vehicle with Transport Mode On

With Transport Mode on, enter the vehicle using the steps below:

  1. Attempt to unlock the vehicle with the key fob.
  2. If the vehicle is not responding to the key fob, press the PEPS door handle switch a few times (if equipped) and then attempt to unlock the vehicle with the key fob.
  3. If the vehicle is not responding to the key fob, the key must be used to enter the vehicle.
  4. Turn the Transport Mode on/off using the vehicle specific procedure.


Turning Off Transport Mode

Transport Mode should be left on while the vehicle is in dealership inventory. In addition, a customer may want to use Transport Mode if the vehicle is going to be stored. The method to turn Transport Mode off or on again is the same.

For the procedure to turn Transport Mode off/on for a specific GM model, refer to Bulletin #20-NA-157.

Turning off Transport Mode on vehicles that are shipped from the assembly plant with feature on is included in the normal PDI process time.
