Service Air Suspension; Tighten Fuel Cap; Turn Signal On; Check Washer Fluid - Hummer H2 2004 Owner's Manual

SERVICE AIR SUSPENSION

If a problem occurs with the suspension system, this
message will appear on the DIC. If this message
appears, stop as soon as possible and turn off the
vehicle. Restart the vehicle and check for the message
on the DIC display. If the message is still displayed,
or appears again when you begin driving, the air
suspension system needs service.

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 the select button will clear it from
the DIC display.

FUEL LEVEL LOW

If the fuel level is low, this message will appear on the
DIC and you will hear a chime. Refuel as soon as
possible. Pressing the select button will acknowledge
this message immediately and clear it from the DIC
display. It will also clear itself after 10 seconds. The low
fuel light near the fuel gage will still remain on in
either case.

TIGHTEN FUEL CAP

If the vehicle's fuel cap is not tightened properly this
message may appear along with the check engine light
on the instrument panel. See Malfunction Indicator
Lamp on page 3-37. Reinstall the fuel cap, making sure
to fully install the cap. See Filling Your 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 will allow fuel to evaporate into
the atmosphere. A few driving trips with the cap properly
installed should turn the light and message off.

CHECK WASHER FLUID

If the washer fluid level is low, this message will appear
on the DIC. Adding washer fluid will clear the message.
Pressing the select button will clear it from the DIC
display. This message will clear itself after 10 seconds
until the next ignition cycle.

TRACTION ACTIVE

When the traction control system has detected that any
of the vehicle's wheels are slipping, the traction
control system will activate and this message will appear
on the DIC. See Traction Control System (TCS) on
page 4-8 for more information.
