Condition

Procedure

Some customers may comment that the Transport
Mode On message is displayed in the DIC and/or the
red battery light is flashing. Transport Mode is intended
for use for vehicles being shipped over long distances,
and includes vehicles shipped into and outside of the
United States and Canada.
Some products will be shipped from the assembly plant
with Transport Mode On. The Transport Mode feature
when enabled 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.
To alert the operator that Transport Mode On is
enabled, the red battery light will be flashing and if
equipped with a DIC, it will display a Transport Mode
On message. Twenty-four hours after transport mode is
turned On, with the vehicle Off, (with exception of 2015
Full-Size SUVs equipped with RPO AVF, and
continuing in later model years without AVF) the key
must be used to enter the vehicle, as the following
functions will be disabled: Passive Entry, Remote
Keyless Entry, Content Theft. For 2015 Full-Size SUVs
(Cadillac Escalade models, Chevrolet Suburban,
Tahoe, GMC Yukon Models), with RPO AVF, and
continuing in later model years without AVF; the
Remote Keyless Entry function will remain enabled
during transport mode, allowing entry without a key.
Exit lighting timers will function but will be reduced.
Note: For PEPS vehicles in Transport Mode On,
the key fob will operate for the Start/Stop button, as
long as the fob is inside the vehicle.

Note: Normal vehicle diagnostics and/or service
procedures should not be performed when
Transport Mode is On. Turn Transport Mode Off
prior to performing system checks or service
procedures.

When the vehicle is running, the only difference in
operation will be the DIC Message and the battery light
flashing. The Passive Entry and Remote Keyless Entry
functions are restored with the ignition in Run.
The mode should be left On while the vehicle is in
dealer inventory. Also a customer may want to use the
mode if the vehicle is going to be stored. The method to
turn the mode Off is the same to turn the mode On.
Refer to the Procedure section.
Tip: The EL-50313 Midtronics GR8 Battery Tester/
Charger must be used for maintaining batteries on
new vehicles in dealer inventory.

With Transport Mode On, enter the vehicle using the
steps below:
1. Attempt to unlock the vehicle with the FOB.
2. If the vehicle is not responding to the FOB, press
the PEPS door handle switch a few times (if
equipped) then attempt to unlock the vehicle with
the FOB.
3. If the vehicle is not responding to the FOB, the key
must be used to enter the vehicle.
4. Turn the Transport Mode On/Off using the vehicle
specific procedure.

Transport Mode is enabled by activating the hazard
flashers, applying the brake pedal, and then turning the

Transport Mode On when enabled and Transport Mode
Off when disabled. For vehicles not equipped with a
DIC, the battery indicator light will constantly flash on
the instrument cluster when Transport Mode is On. This
feature can be used as many times as necessary if the
vehicle is to be stored for an extended period of time.

To turn Transport Mode On/Off, push and hold the Start/
Stop button while the brake is applied for 15 seconds or
until the Transport Mode On/Off message is displayed.

RKE system to only work when the ignition is On or the
BCM is awake (approximately 20 minutes after
ignition Off).
Note: Vehicles that are shipped from the assembly
plant with Transport Mode On, turning the feature
Off is included in the normal PDI process time. No
additional warranty claims should be submitted to
disable or enable this feature.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
