SERVICE CHARGING SYSTEM
On some vehicles, if there is a problem with the battery
charging system, this message will appear on the
DIC. The battery will not be charging at an optimal rate
and the vehicle will lose the ability to enter the fuel
economy mode. The vehicle is safe to drive, however
you should have the electrical system checked by
your GM dealer. Pressing any of the four DIC buttons or
the trip odometer reset stem will clear the message
from the DIC display.
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 cluster. 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.
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 4-9 for more information.
TRANS HOT IDLE ENGINE
If the transmission fluid gets hot, this message will
appear on the DIC along with a continuous chime.
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
will clear and the chime will stop when the fluid
temperature reaches a safe level.
