Vehicle Reminder; Messages - GMC 2011 Yukon/Yukon XL Owner's Manual

5-48 Instruments and Controls
TRANSMISSION HOT
IDLE ENGINE
If you drive the vehicle
while the transmission fluid is
overheating and the transmission
temperature warning is displayed
on the instrument panel cluster
and/or DIC, you can damage the
transmission. This could lead
to costly repairs that would not
be covered by the warranty.
Do not drive your vehicle with
overheated transmission fluid
or while the transmission
temperature warning is displayed.
This message displays along with a
sound if the transmission fluid in the
vehicle gets hot. Driving with the
transmission fluid temperature high
can cause damage to the vehicle.
Stop the vehicle and let it idle to
allow the transmission to cool.
This message clears and the chime
stops when the fluid temperature
reaches a safe level.

CHECK TRAILER WIRING
On vehicles with the Integrated
Trailer Brake Control (ITBC) system,
this message may display and a
chime may sound when one of the
following conditions exists:
A trailer with electric brakes
becomes disconnected from
the vehicle.
If the disconnect occurs while
the vehicle is stopped, this
message clears itself after a
short time.
If the disconnect occurs while
the vehicle is moving, this
message stays on until the
ignition is turned off.
There is a short in the wiring to
the electric trailer brakes.
When this message displays,
power is no longer available to the
trailer brakes.
As soon as it is safe to do so,
carefully pull the vehicle over to the
side of the road and turn the ignition
off. Check the wiring connection to
the trailer and turn the ignition back
on. This message clears if the trailer
is reconnected. This message also
clears if you acknowledge it. If this
message still displays, either the
vehicle or the trailer needs service.
See your dealer.
