Tire Pressure Light
For vehicles with the tire
pressure light, it comes on
briey when the engine
is started. If it does not,
have the vehicle serviced
by your dealer/retailer.
If the system is working
normally the indicator light
then goes off.
This light also comes on when one or more of the tires
is signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC) can accompany the light. SeeDIC
Warnings and Messages on page 3-60for more
information.
Stop and check the tires as soon as it is safe to do so.
If underinated, inate the tire to the proper pressure.
SeeTires on page 6-46for more information.
If a problem is detected with the Tire Pressure Monitor
System, this light ashes for approximately 60 seconds
and then stays on for the remainder of the ignition
cycle. SeeTire Pressure Monitor System on page 6-55
for 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 makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This comes on briey
while starting the engine.
If it does not come on,
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.
3-50

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:Modications 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. Modications 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. See
Accessories and Modifications on page 6-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre 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 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.
3-51

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
doing the following:
Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 6-8. 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, misring, 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 6-5.
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.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 2-24. Press the bottom of the Acc. button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the
check engine light, will light up and the ignition will be
on, but the engine will not start — press the bottom
of the Acc. button only briey, less than ve seconds,
the accessory power mode will be turned on, but not
the ignition. After the bulb check, press and release
the Acc. button again to turn the ignition off and avoid
draining the vehicle’s battery.
The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if the battery has
recently been replaced or if the battery has run down.
The diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This can take several days of routine driving. If this
has been done and the vehicle still does not pass the
inspection for lack of OBD II system readiness, your
dealer/retailer can prepare the vehicle for inspection.
3-53

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,outside temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. SeeDIC Warnings and
Messages on page 3-60andEngine Oil on page 6-15.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil. United States

Fuel Gage
The fuel gage indicates
about how much fuel is left
when the ignition is
turned on.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
When the needle approaches the low fuel symbol, LOW
FUEL will appear on the Driver Information Center (DIC)
display. At this time, there is still have a little fuel left,
but the vehicle’s fuel tank should be lled soon.Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in
10 minutes if fuel has not been added to the vehicle.
Here are ve things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads the full symbol.
It takes more (or less) fuel to ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank’s
capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty when
the ignition is turned off.
The gage reading may change slightly within the
rst several minutes after starting the vehicle.
