2005 HUMMER H2 display

At approximately 265°F (130°C), the DIC will display a
TRANSMISSION HOT message and the transmission
will enter a transmission protection mode. When
the transmission enters the protection mode, you may
notice a change in the transmission shifting patterns.
The transmission will return to normal shifting patterns
when the transmission uid temperature falls below
260°F (127°C).
If the transmission uid reaches temperatures of
approximately 275°F (135°C) or greater, the DIC will
display a TRANS HOT IDLE ENGINE warning message
and a chime will sound. Pull the vehicle off the
roadway when it is safe to do so. Set the parking brake,
place the transmission in PARK (P) and allow the
engine to idle until the transmission temperature falls
below 260°F (127°C). If the transmission continues
to operate above 265°F (130°C), please contact your
nearest dealer or the GM Roadside Assistance Center.
SeeDriver Information Center (DIC) on page 3-43
for further information.
Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the transmission.
This could lead to costly repairs that would not
be covered by your warranty. Do not drive your
vehicle while the transmission temperature gage
reading is above normal. See your dealer for service.The following situations can cause the transmission to
operate at higher temperatures:
Towing a trailer,
hot outside air temperatures,
hauling a large or heavy load,
low transmission uid level,
high transmission uid level,
restricted air ow to the radiator.
A temporary solution to hotter transmission operating
temperatures may be to let the transmission cool down.
If the transmission is operated at higher temperatures
on a frequent basis, seeScheduled Maintenance
on page 6-4for the proper transmission maintenance
intervals.

Tow/Haul Mode Light
This light is displayed
when the tow/haul mode
has been activated.
For more information, see “Tow/Haul Mode” under
Towing a Trailer on page 4-68.
Fuel Gage
When the ignition is on, the fuel gage tells you about
how much fuel you have left in your tank.
The gage will rst indicate empty before you are out of
fuel, and you should get more fuel as soon as
possible.
United StatesCanada
3-42

Here are some situations you may experience with your
fuel gage. None of these indicate a problem with the
fuel gage.
At the gas station, the fuel pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the tank’s
capacity to ll the tank.
The gage goes back to empty when you turn off the
ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on briey when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
To turn it off, add fuel to the fuel tank. SeeFuel on
page 5-5.

DIC Operation and Displays
The Driver Information Center (DIC) comes on when the
ignition is on. After a short delay, the DIC will display
the information that was last displayed before the engine
was turned off.
If a problem is detected, a warning message will appear
on the display. Pressing any of the four DIC buttons
or the trip odometer reset stem will acknowledge or clear
most current warnings or service messages. Some
warnings that cannot be acknowledged or cleared are:
ENGINE OVERHEATED, OIL PRESSURE LOW,
REDUCED ENGINE POWER, TRANS HOT IDLE
ENGINE. These warnings must be dealt with
immediately and therefore cannot be cleared until the
problem has been corrected.You should take any message that appears on the
display seriously and remember that clearing the
message will only make the message disappear, not
correct the problem.
The DIC has different modes which can be accessed by
pressing the four DIC buttons located on the steering
wheel. These buttons are trip information, fuel
information, personalization and select. The button
functions are detailed in the following pages.
Trip Information Button
Press the trip information button to scroll through the
ODOMETER, TRIP A, TRIP B, TIRE PRESSURES,
TIMER and ENGINE HOURS.
Odometer:Press the trip information button until

the total distance the vehicle has been driven in
either miles or kilometers. Pressing the reset stem
located on the instrument cluster with the vehicle off will
also display the odometer.
Trip A:Press the trip information button until TRIP A
appears on the display. This mode shows the current
distance traveled since the last reset for TRIP A in either
miles or kilometers.
3-44

Trip B:Press the trip information button until TRIP B
appears on the display. This mode shows the current
distance traveled since the last reset for TRIP B in either
miles or kilometers.
To reset TRIP A or TRIP B information, press and hold
the select button for one second while in one of the
trip modes. This will reset the information for TRIP A or
TRIP B.
You can also reset TRIP A or TRIP B while they are

front tire.
RF TIRE shows the tire pressure for the right
front tire.
LR TIRE shows the tire pressure for the left
rear tire.
RR TIRE shows the tire pressure for the right
rear tire.
Timer:The DIC can be used as a timer. Press the
select button while TIMER is displayed to start the timer.
The display will show the amount of time that has
passed since the timer was last reset, not including time

liters per 100 kilometers (L/100 km) your vehicle is
getting based on current and past driving conditions.Press and hold the select button for one second while
AVG ECON is displayed to reset the average fuel
economy. Average fuel economy will then be calculated
starting from that point. If the average fuel economy is not
reset, it will be continually updated each time you drive.
Engine Oil Life System:Press the fuel information
button until ENGINE OIL LIFE appears on the display.
The Engine Oil Life System shows an estimate of
the oil’s remaining useful life. It will show 100% when

If there is more than one message that needs to
be displayed they will appear one after another. Some
messages may not require immediate action, but
you should press any of the four DIC buttons located on
the steering wheel or the trip odometer reset stem
located on the instrument panel cluster to acknowledge
that you received the messages and clear them from
the display. Some messages cannot be cleared from the
display because they are more urgent. These messagesrequire action before they can be removed from the DIC
display. You should take any messages that appear

messages will only make the messages disappear,
not correct the problem. The following are the possible
messages that can be displayed and some information
about them.

If the oil level in the vehicle is low, this message will
appear on the DIC. Check the oil level and correct it as
necessary. You may need to let the vehicle cool or
warm up and cycle the ignition to be sure this message
will clear. Once the problem is corrected, pressing
any of the four DIC buttons or the trip odometer reset
stem will clear this message from the DIC display. This
message will clear itself after 10 seconds until the
next ignition cycle.
