TRANS (Transmission) HOT IDLE
ENGINE
Notice: If you drive your 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 your warranty. Do not drive your
vehicle with overheated transmission fluid
or while the transmission temperature warning
is displayed.
If the transmission fluid in the vehicle gets hot, this
message will appear on the DIC along with a
continuous chime. 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 will
clear and the chime will stop when the fluid
temperature reaches a safe level. See
Transmission Temperature Gage on page 257.
TRANS (Transmission) IN WARM UP
(Allison Transmission
When temperatures are very cold, the transmission
will prevent certain operations such as shifts to
some 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.
