The vehicle is equipped with this cluster or one very
similar to it. It has indicator warning lights that are
explained on the following pages. Be sure to read
about them.
Speedometer and Odometer
The speedometer shows the vehicle’s speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer, located on the Driver Information Center
(DIC) display, shows how far the vehicle has been
driven, in either miles or kilometers. SeeDIC Controls
and Displays (Base Level DIC) on page 3-52orDIC
Controls and Displays (Uplevel DIC with Trip Computer)
on page 3-60for more information.
If the vehicle has the Head-Up Display (HUD) the speed
will also be displayed on the HUD screen.
If a vehicle has to have a new odometer installed, a
new one can be set to the mileage total of the old
odometer, if that can be done. If it cannot, than it will be
set at zero and a label must be put on the driver’s
door to show the old mileage reading when the new
odometer was installed.
Trip Odometer
The trip odometer, located in the Driver Information
Center (DIC), tells how far the vehicle has driven since it
was last reset. The miles (kilometers) for two different
trips can be viewed. SeeDIC Controls and Displays
(Base Level DIC) on page 3-52orDIC Controls and
Displays (Uplevel DIC with Trip Computer) on page 3-60
for more information on setting the trip odometer.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not be
covered by your warranty. Do not operate the engine
with the tachometer in the shaded warning area.
3-37

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.Notice:Modi cations made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modi cations to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-3.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come 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 may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
