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, there is
a problem with the air suspension system. See your
dealer for service.

SERVICE BRAKE SYSTEM

If a problem occurs with the brake 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, there is a problem with the brake
system. See your dealer for service. 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 3-39. Reinstall the fuel cap, making sure
to fully install the 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.
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.
