Hummer 2008 H2 - Manual (Page 212)

TIGHTEN GAS CAP
This message may display 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 3-42. Reinstall the fuel cap
fully. See Filling the Tank on page 5-7. 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
This message displays when the Tire Pressure Monitor
System (TPMS) is re-learning the tire positions on your
vehicle. 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 5-67, Tire Pressure
Monitor System on page 5-62, and Inflation - Tire
Pressure on page 5-61 for more information.
TRACTION CONTROL OFF
This message displays when you turn off the Traction
Control System (TCS) or when the TCS has been
automatically disabled. Adjust your driving accordingly.
See Traction Control System (TCS) on page 4-5 and
StabiliTrak
® System on page 4-7 for more information.
TCS may be automatically disabled due to overheating,
which could occur if the TCS activates continuously
for an extended period of time.
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.
