GMC 2006 Sierra - Manual (Page 242)

TRANS (Transmission) IN WARM UP
(Allison Transmission
® Only)
When temperatures are very cold, the transmission
will prevent certain operations such as shifts to certain
ranges and engaging the torque converter clutch to
protect against damage. When active, the DIC will
display the message TRANS IN WARM UP.
TURN SIGNAL ON
If a turn signal is left on for 3/4 of a mile (1.2 km), this
message will appear on the display and you will hear a
chime. Move the turn signal/multifunction lever to the
off position. Pressing any of the four DIC buttons will
acknowledge the message and clear it from the DIC
display. If your vehicle does not have the four DIC
buttons, pressing the trip odometer reset stem will
acknowledge the message and clear it from the
DIC display.
DIC Vehicle Customization
Your vehicle may have customization capabilities that
allow you to program some features to one setting based
on your preference. All of the customizable options listed
may not be available on your vehicle. Only the options
available will be displayed on your Driver Information
Center (DIC).
The default settings for the customization features were
set when your vehicle left the factory, but may have been
changed from their default state since then.
To change feature preferences, make sure the
ignition is on and the vehicle is in PARK (P). Press
the customization button to scroll through the available
customizable options.
After pressing the customization button, VEHICLE
SETTINGS will momentarily display before going to a
customization option.
Lock Doors (Automatic Transmission only)
If you have an automatic transmission vehicle, press the
customization button until LOCK DOORS appears in the
display. To select your preference for automatic locking,
press the select button while LOCK DOORS is displayed
on the DIC. Pressing the select button will scroll through
the following choices:
LOCK DOORS: IN GEAR (default): The doors will lock
when the vehicle is shifted out of PARK (P).
LOCK DOORS: WITH SPEED: The doors will lock
when the vehicle speed is above 8 mph (13 km/h) for
three seconds.
Choose one of the available options and press the
customization button while it is displayed on the DIC
to select it and move on to the next feature. For
more information on automatic door locks, see
Programmable Automatic Door Locks on page 2-10.
