Tire Pressure Light
If the vehicle has a tire pressure
monitoring system, the tire pressure
light provides information about tire
pressures and the Tire Pressure
Monitoring System. The light should
come on brie y as the engine is
started. If it does not, have the
vehicle serviced by your dealer/
retailer.When the Light is On Steady
This indicates that one or
more of the tires are signi cantly
underin ated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. SeeDIC
Warnings and Messages on
page 3-56for more information.
Stop and check the tires as soon
as it is safe to do so. If underin ated,
in ate to the proper pressure.
SeeTires on page 5-36for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there could be
a problem with the Tire Pressure
Monitor System. The light ashes for
about a minute and stays on steady
for the remainder of the ignition
cycle. This sequence repeats with
every ignition cycle. SeeTire
Pressure Monitor System on
page 5-43for more information.
Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation
of the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light comes on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer/
retailer.

If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is
continually driven with this
light on, after a while, the
emission controls might not
work as well, the vehicle’s fuel
economy might not be as good,
and the engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.Notice:Modi cations made to
the engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect the
vehicle’s emission controls and
can cause this light to come on.
Modi cations to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test.
SeeAccessories and
Modifications on page 5-3.This light comes on during a
malfunction in one of two ways:
Light Flashing:A mis re condition
has been detected. A mis re
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the vehicle.
Turn the key off, wait at least
10 seconds, and restart the engine.
If the light is still ashing, follow the
previous steps and see your dealer/
retailer for service as soon as
possible.

Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by checking the
following items:
Make sure the fuel cap is fully
installed. SeeFilling the 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 allows fuel to evaporate into
the atmosphere. A few driving
trips with the cap properly
installed should turn the light off.
If the vehicle has been driven
through a deep puddle of water,
the vehicle’s electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, mis ring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.If one or more of these conditions
occurs, change the fuel brand
used. It will require at least one
full tank of the proper fuel to turn
the light off.
SeeGasoline Octane on
page 5-5.
If none of the above have made the
light turn off, your dealer/retailer can
check the vehicle. The dealer/retailer
has the proper test equipment and
diagnostic tools to x any mechanical
or electrical problems that might
have developed.
