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.

If the light comes on and stays on, it means that oil isnot flowing through the engine properly. The vehiclecould be low on oil and it might have some othersystem problem.

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.
4-61

The DIC comes on when the ignition is on. After a shortdelay, the DIC will display the information that waslast displayed before the engine was turned off.
The top line of the DIC display shows the vehicle systeminformation and the warning/status messages. Thebottom line of the DIC display shows the odometer onthe left side. The bottom line of the DIC display alsoshows a digital speedometer on the right side.
If a problem is detected, a warning message will appearon the display. Be sure to take any message thatappears on the display seriously and remember thatclearing the message will only make the messagedisappear, not correct the problem.
DIC Operation and Displays
The Driver InformationCenter (DIC) has differentdisplays which can beaccessed by pressing theDIC buttons located onthe instrument panel, to theleft of the steering wheel.

Trip/Fuel Display Menu Items
3(Trip/Fuel):The following display menu items
can be displayed by pressing the trip/fuel button:
TRIP A or TRIP B
These displays show the current distance traveled sincethe last reset for each trip odometer in eitherkilometers (km) or miles (mi). Both odometers can beused at the same time. Each trip odometer can be resetto zero separately by pressing and holding theset/reset button for a few seconds while the desired tripodometer is displayed.
FUEL RANGE
This display shows the approximate number ofremaining kilometers (km) or miles (mi) you can drivewithout refilling the fuel tank. This estimate is based onthe current driving conditions and will change if thedriving conditions change. For example, if you aredriving in traffic and making frequent stops, the displaymay read one number, but if you enter the freeway,the number may change even though you still have thesame amount of fuel in the fuel tank. This is becausedifferent driving conditions produce different fueleconomies. Generally, freeway driving produces betterfuel economy than city driving.
Once the range drops below an estimated 64 km(40 miles) remaining, the display will show FUELRANGE LOW.
If your vehicle is low on fuel, the FUEL LEVEL LOWmessage will be displayed. See “FUEL LEVELLOW” underDIC Warnings and Messages on page 4-67for more information.
AVERAGE ECONOMY (AFE)
This display shows the approximate average liters per100 kilometers (L/100 km) or miles per gallon (mpg).This number is calculated based on the numberof L/100 km (mpg) recorded since the last time thisdisplay was reset. To reset this display, press theset/reset button. The display will return to zero.
INST (Instantaneous) ECONOMY (IFE)
This display shows the current fuel economy in eitherliters per 100 kilometers (L/100 km) or miles pergallon (mpg). This number reflects only the fuel economythat the vehicle has right now and will change frequentlyas driving conditions change. Unlike average economy,this display cannot be reset.
FUEL USED
This display shows the number of liters (L) orgallons (gal) of fuel used since the last reset of thisdisplay. To reset this display, press the set/reset button.The display will return to zero.

BATTERY VOLTAGE
This display shows the current battery voltage. If thevoltage is in the normal range, the value will display. Forexample, the display may read BATTERY VOLTAGE13.2 VOLTS. If the voltage is low, the display will showLOW. If the voltage is high, the display will showHIGH. Your vehicle’s charging system regulates voltagebased on the state of the battery. The battery voltagemay fluctuate when viewing this information on the DIC.This is normal. SeeCharging System Light onpage 4-52for more information.
If there is a problem with the battery charging system,the DIC will display a message. SeeDIC Warningsand Messages on page 4-67andElectric PowerManagement on page 4-33for more information.
