GMC Envoy XL Denali Automobile User Manual


 
TIGHTEN FUEL CAP
If the vehicle’s fuel cap is not tightened properly, this
message may appear on the DIC and a chime will
sound. Fully reinstall the fuel cap. See Filling the Tank
on page 5-8. 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. The DIC message will remain on
until the message is cancelled with the return button
on the steering wheel. The DIC message will also
be cancelled if the ignition is turned off.
The DIC message and the Service Engine Soon light
may come on again during a second trip if the fuel cap is
still not tightened properly. See Malfunction Indicator
Lamp on page 3-42 for more information.
TRACTION CONTROL OFF
The TRACTION CONTROL OFF message will be
displayed when you momentarily press the StabiliTrak
®
button located on the transmission shift handle. In
this mode, stability control and the brake-traction control
are functional. Engine speed management will be
modified and the driven wheels can spin more freely.
For more details on this mode, see StabiliTrak
®
System
on page 4-9.
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. Press the select button to acknowledge this
message and clear it from the DIC display.
