Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have ormight begin programs to inspect the emission controlequipment on the vehicle. Failure to pass this inspectioncould prevent getting a vehicle registration.
Here are some things to know to help the vehicle passan inspection:
•The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if thekey is in ON/RUN and the light is not on.
•The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determinesthat critical emission control systems have not beencompletely diagnosed by the system. The vehiclewould be considered not ready for inspection.This can happen if the battery has recently beenreplaced or if the battery has run down. Thediagnostic system is designed to evaluate criticalemission control systems during normal driving.This can take several days of routine driving. If thishas been done and the vehicle still does notpass the inspection for lack of OBD II systemreadiness, your dealer/retailer can preparethe vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance candamage the engine. The repairs would not becovered by the vehicle warranty. Always follow themaintenance schedule in this manual for changingengine oil.
This light comes on briefly while starting the engine.If it does not, have the vehicle serviced by yourdealer/retailer. If the system is working normally theindicator light then goes off.

Highbeam On Light
This light comes on whenthe high-beam headlampsare in use.
SeeHeadlamp High/Low-Beam Changer on page 4-6for more information.
Fuel Gage
The fuel gage showsapproximately how muchfuel is in the tank. Itworks only when theengine is on.
An arrow on the fuel gage indicates the side of thevehicle the fuel door is on.
If the fuel supply gets low, the FUEL LEVEL LOWmessage appears in the Driver Information Center anda single chime sounds. SeeDIC Warnings andMessages on page 4-67for more information.
Here are a few situations that may occur with the fuelgage. All of these situations are normal and do notindicate that anything is wrong with the fuel gage:
•At the gas station the gas pump shuts off before the
gage reads full.
•The gage may change when the vehicle is turning,
stops quickly or accelerates quickly.
•It takes a little more or less fuel to fill the tank than
the gage indicated. For example, the gage mayhave indicated that the tank was half full, butit actually took a little more or less than half thetank’s capacity to fill the tank.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives you thestatus of many of your vehicle’s systems. The DIC isalso used to display warning/status messages. Allmessages will appear in the DIC display located at thebottom of the instrument panel cluster, below thetachometer and speedometer. The DIC buttons arelocated on the instrument panel, to the left of thesteering wheel.
