CHECK GAS CAP

This message may display if the fuel cap is not on, or is
not fully tightened. The check gas cap light also appears
on the instrument panel cluster. See Check Gas Cap
Light
on page 3-47. Check the fuel cap to ensure that it is
on properly. The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A loose
or missing fuel cap allows fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn this message off. See Filling the
Tank
on page 5-8 for more information.

This message displays while the ignition is in ON/RUN.
Press any of the DIC buttons to acknowledge this
message and to clear it from the screen.

This message continues to display for two seconds
if it has not been acknowledged when the engine
is turned off. It also re-displays for two seconds if the
message has been acknowledged, but the condition
still exists when the engine is turned off.

If the condition still exists, the message re-appears
when the engine is turned on.

CHECK TIRE PRESSURE

On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in one
or more of the vehicle’s tires needs to be checked. This
message also displays LEFT FRONT, RIGHT FRONT,
LEFT REAR, or RIGHT REAR to indicate which tire
needs to be checked. You can receive more than one tire
pressure message at a time. To read the other messages
that may have been sent at the same time, press the
set/reset button. If a tire pressure message appears on
the DIC, stop as soon as you can. Have the tire pressures
checked and set to those shown on the Tire Loading
Information label. See Tires on page 5-54, Loading the
Vehicle
on page 4-20, and Inflation - Tire Pressure on
page 5-61
. The DIC also shows the tire pressure values.
See DIC Operation and Displays on page 3-48. If the tire
pressure is low, the low tire pressure warning light comes
on. See Tire Pressure Light on page 3-39.

This message displays while the ignition is in ON/RUN.
Press any of the DIC buttons to acknowledge this
message and to clear it from the screen.

This message continues to display for two seconds
if it has not been acknowledged when the engine
is turned off. It also re-displays for two seconds if the
message has been acknowledged, but the condition
still exists when the engine is turned off.

If the condition still exists, the message re-appears
when the engine is turned on.
