Service engine soon
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine’s emission control
systems may be malfunctioning. The light may illuminate without a
driveability concern being noted. The vehicle will usually be drivable and
will not require towing.
Light turns on solid:
Temporary malfunctions may cause the light to illuminate. Examples are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the fuel cap. After three driving cycles
without these or any other temporary malfunctions present, the light
should turn off. (A driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No additional vehicle service is
required.
If the light remains on, have your vehicle serviced at the first available
opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.

Checkfuel cap (if equipped)
Illuminates when the fuel cap is not
installed correctly. Check the fuel
cap for proper installation. When
the fuel filler cap is properly
re-installed, the light(s) will turn off
after a period of normal driving. Continuing to operate the vehicle with
the fuel cap mis-installed can activate theService Engine Soon/Check
Enginewarning light.
It may take a long period of time for the system to detect an
improperly installed fuel filler cap.
For more information, refer toFuel filler capin theMaintenance and
carechapter.
Air bag readiness
Illuminates to confirm that the air
bags (front or side) are operational.
If the light fails to illuminate,
continues to flash or remains on,
have the system serviced
immediately.
Safety belt
Illuminates to remind you to fasten
your safety belts. For more
information, refer to theSeating
and safety restraintschapter.
Brake system warning
To confirm the brake system
warning light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to START position, the light will momentarily illuminate prior to
reaching the START position). It also illuminates if the parking brake is
engaged. If the brake system warning light does not illuminate as
described, seek service immediately. Illumination after the parking brake
is released indicates low brake fluid level or a brake system malfunction
and the brake system should be serviced immediately by a qualified
technician. Refer toBrakesin theDrivingchapter for more information.

Check gage (if equipped)
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. Refer toEngine
coolant temperature gauge, Engine oil pressure gaugeorFuel gauge
in this chapter for more information.
Oil pressure/Engine coolant
Illuminates when the engine coolant
temperature is above the normal
range or the engine oil pressure is
outside normal range. Check the
engine oil and coolant level refer to
Adding engine oilandAdding coolantin theMaintenance and care
chapter.
Anti-lock brake system (ABS)
To confirm the anti-lock brake
system (ABS) warning light is
functional it will momentarily
illuminate when the ignition is
turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to the START position, the light will momentarily illuminate just
prior to reaching the START position). If the light remains on, continues
to flash or fails to illuminate, have the ABS serviced immediately. If the
ABS light remains on, it means the anti-lock brake system has
malfunctioned and is disabled, however, the normal brake system will
still function unless the brake warning light also remains illuminated and
parking brake is off. Refer toBrakesin theDrivingchapter for more
information.

Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the
indicated area between the“H”and
“C”). If it enters the red section, the
engine is overheating. Stop the
vehicle as soon as safely possible,
switch off the engine immediately
and let the engine cool. Refer to
Engine coolantin theMaintenance and carechapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.
