TIGHTEN GAS CAP
This message may display and a chime may be heard
along with the check engine light on the instrument
panel cluster if the vehicle’s fuel cap is not tightened
properly. See Malfunction Indicator Lamp on page 3-34.
Reinstall the fuel cap fully. See Filling the Tank on
page 5-10. The diagnostic system can determine if
the fuel cap has been left off or improperly installed.
A loose or missing fuel cap allows fuel to evaporate
into the atmosphere. A few driving trips with the
cap properly installed should turn this light and
message off.
TIRE LEARNING ACTIVE
If your vehicle has the Tire Pressure Monitor System
(TPMS), this message displays when the system
is re-learning the tire positions on your vehicle.
See DIC Operation and Displays on page 3-41 for more
information. The tire positions must be re-learned
after rotating the tires or after replacing a tire or sensor.
See Tire Inspection and Rotation on page 5-70,
Tire Pressure Monitor System on page 5-65, and
Inflation - Tire Pressure on page 5-63 for more
information.
TRACTION CONTROL OFF
If your vehicle has StabiliTrak, this message displays
when the Traction Control System (TCS) is turned
off. Adjust your driving accordingly. See StabiliTrak
System on page 4-6 for more information.
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.
This message displays along with a chime 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.
TURN SIGNAL ON
This message displays and a chime sounds if a turn
signal is left on for 3/4 of a mile (1.2 km). Move the turn
signal/multifunction lever to the off position.
