Check Engine Light

This instrument panel-mounted light will
illuminate under a variety of conditions
when the On-Board Diagnostics II (OBD
II) system detects a problem that
requires attention.
If the Check Engine Light is lit steadily,
verify that the fuel tank cap is present
and securely fastened. Turn it clockwise
until a "ratcheting" sound is heard, sig-
naling that it is secure. If this is the
cause of the condition, a few driving
trips with the cap installed properly
should turn the light off.
If you recently traveled through water,
the electrical system may be wet. The
condition will usually correct itself when
the electrical system dries out.
If you are low on fuel, adding fuel should
correct the condition. If you have
changed fuel brands recently, this could
be the cause as well. See the Gasoline
Octane section in your Owner Manual.
If the light remains on, have the vehicle
checked at your dealership or a qualified
service center.
See Section 3 of your Owner Manual.

Tire Inflation Monitor

If equipped, the Tire Inflation Monitor
alerts you to a large change in tire
pressure. If the pressure in one of your
vehicle's tires becomes 12 psi (83 kPa)
lower than the other three tires, the
LOW TIRE PRESSURE message will
appear.
When this message comes on, you
should stop as soon as possible, check
the tire pressure and inspect the tires
for possible damage. The LOW TIRE
PRESSURE message will remain on
until you reset the system.
Below is one method for resetting the
Tire Inflation Monitor system.
• With the ignition position at ON, pull
the interior lamps control to the ON
and OFF settings three times.
(See your Owner Manual for an
alternate resetting method.)
Note: The Tire Inflation Monitor can
alert you about a low tire, but it doesn't
replace normal tire maintenance.
See Section 5 of your Owner Manual.
