SERVICE BRAKE SYSTEM
If there is a problem with the brake system, this
message will be displayed 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 brake system needs
service. See your dealer.
SERVICE CHARGING SYSTEM
On some vehicles, if there is a problem with the
battery charging system, this message will appear
on the DIC. Under certain conditions, the battery
warning light may also turn on in the instrument
panel cluster. See Battery Warning Light on
page 251. 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 dealer. Pressing any of
the four DIC buttons will acknowledge the message
and clear it from the DIC display. If your vehicle
does not have the four DIC buttons, pressing the
trip odometer reset stem will acknowledge the
message and clear it 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.
See Malfunction Indicator Lamp on page 258.
Fully reinstall the fuel cap. See Filling the
Tank on page 475. 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 had detected
that any of the vehicle's wheels are slipping,
the traction control system will activate and this
message will appear on the DIC. For more
information, see Traction Assist System (TAS)
on page 363.
