Service engine soon
Your vehicle is
equipped with a
computer that monitors
the engine's emission
control system. This
system is commonly known as the On Board
Diagnostics System (OBD II). The OBD II system
protects the environment by ensuring that your
vehicle continues to meet government emission
standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates
when the ignition is first turned to the ON position
to check the bulb. 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.
What you should do if the Service Engine Soon
light illuminates
Light turns on solid:
This means that the OBD II system has detected a
malfunction.
Temporary malfunctions may cause yourService
Engine Soonlight to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may
misfire or run poorly.)
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 good quality fuel and/or
properly installing and securely tightening the gas
cap. After three driving cycles without these or any
other temporary malfunctions present, theService
Engine Soonlight 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 theService Engine Soonlight 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.
Low fuel
Illuminates as an early
reminder of a low fuel
condition indicated on
the fuel gauge. The
light comes on when there is approximately 1/16th
of a tank indicated on the fuel gauge (refer toFuel
Gaugein this chapter for more information). The
ignition must be in the ON position for this lamp to
illuminate. The lamp will also illuminate for several
seconds after the ignition is turned to the ON
position regardless of the fuel level.
O/D off (if equipped)
Illuminates when the
transmission control
switch has been
pushed. When the light
is on, the transmission does not shift into overdrive.
If the light does not come on when the transmission

control switch is depressed or if the light flashes
when you are driving, have your vehicle serviced.
Traction ControlYactive
This light momentarily
illuminates when the
ignition is turned to
ON. It also illuminates
when the Traction Controlysystem begins applying
and releasing the brakes and adjusting the engine
characteristics to limit a wheelspin condition. It will
be lit for a minimum of four seconds or for the
duration of the Traction Controlyevent.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS)
Momentarily illuminates
when the ignition is
turned to the ON
position and the engine
is off. If the light remains on, continues to flash or
fails to illuminate, have the system serviced
immediately. With the ABS light on, the anti-lock
brake system is disabled and normal braking is still
effective unless the brake warning light also remains
illuminated with parking brake released.
Brake system warning
Momentarily illuminates
when the ignition is
turned to the ON
position and the engine
is off. If brake warning lamp does not illuminate at
this time, seek service immediately. Also illuminates
when the parking brake is engaged. Illumination
after releasing the parking brake indicates low brake
fluid level and the brake system should be inspected
immediately.

Illuminates when the
coolant level in the
coolant reservoir is low
and more needs to be
added. This lamp will also illuminate when the
ignition is turned to ON and the engine is off. For
more information on adding engine coolant, refer to

GAUGES
Base instrument cluster gauges
Optional instrument cluster gauges
Fuel gauge
Displays approximately
how much fuel is in the
fuel tank (when the
key is in the ON
position). The fuel gauge may vary slightly when the
vehicle is in motion. The ignition should be in the
OFF position while the vehicle is being refueled.
When the gauge first indicates empty, there is a
small amount of reserve fuel in the tank. When
refueling the vehicle from empty indication, the
amount of fuel that can be added will be less than
the advertised capacity due to the reserve fuel.

Trip odometer
Registers the
kilometers (miles) of
individual journeys.
Press the reset button
until a ªTº appears in
the display (this
represents the trip
mode). Press and hold
the button for
2.5 seconds to reset.
Battery voltage gauge
This gauge shows the
battery voltage when
the ignition is in the
ON position. If the
pointer moves and stays outside the normal
operating range (as indicated), have the vehicle's
electrical system checked as soon as possible.
Engine oil pressure gauge
This shows the engine
oil pressure in the
system. Sufficient
pressure exists as long
as the needle remains in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure, stop the vehicle
as soon as safely possible and switch off the engine
immediately. Check the oil level. Add oil if needed
(refer toEngine oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle
checked at your dealership or by a qualified
technician.
