.It takes a little more or less fuelto fill up than the fuel gaugeindicated. For example, thegauge may have indicated thetank was half full, but it actuallytook a little more or less thanhalf the tank's capacity to fillthe tank.
.The gauge moves a little whileturning a corner or speeding up.
.The gauge does not go back toempty when the ignition isturned off.

Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows theengine oil pressure in psi (poundsper square inch) or kPa (kilopascals)when the engine is running.
Oil pressure may vary with enginespeed, outside temperature and oilviscosity, but readings above thelow pressure zone indicate thenormal operating range.
Areadinginthelowpressurezonemay be caused by a dangerouslylow oil level or other problemcausing low oil pressure.

Center (DIC) can also appear. SeeBattery Voltage and ChargingMessages011 2for moreinformation. This light could indicatethat there are problems with agenerator drive belt, or that there isan electrical problem. Have itchecked right away. If the vehiclemust be driven a short distance withthe light on, turn off accessories,such as the radio and airconditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’semission control on-boarddiagnostic system. If this light is onwhile the engine is running, amalfunction has been detected andthe vehicle may require service. Thelight should come on to show that itis working when the ignition is inON/RUN and the engine is notrunning. SeeIgnitionPositions0176.
Malfunctions are often indicated bythe system before any problem isnoticeable. Being aware of the lightand seeking service promptly whenit comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’sabilitytopass
an Emissions Inspection/
Maintenance test. See
Accessories and
Modifications0216.
If the light is flashing :Amalfunction has been detected thatcould damage the emission controlsystem and increase vehicleemissions. Diagnosis and servicemay be required.

If towing a trailer, reduce theamount of cargo being hauled assoon as possible.
If the light continues to flash, find asafe place to park. Turn the vehicleoff and wait at least 10 secondsbefore restarting the engine. If thelight is still flashing, follow theprevious guidelines and see yourdealer for service as soon aspossible.
If the light is on steady :Amalfunction has been detected.Diagnosis and service may berequired.
Check the following:
.Alooseormissingfuelcapmaycause the light to come on. SeeFilling the Tank0200.Afewdriving trips with the capproperly installed may turn thelight off.
.Poor fuel quality can causeinefficient engine operation andpoor driveability, which may goaway once the engine is warmedup. If this occurs, change thefuel brand. It may require at
least one full tank of the properfuel to turn the light off. SeeFuel0198.
If the light remains on, see yourdealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an EmissionsInspection/Maintenance test, thetest equipment will likely connect tothe vehicle's Data LinkConnector (DLC).
The DLC is under the instrumentpanel to the left of the steeringwheel. Connecting devices that arenot used to perform an EmissionsInspection/Maintenance test or toservice the vehicle may affectvehicle operation. SeeAdd-OnElectrical Equipment0212.Seeyour dealer if assistance is needed.
The vehicle may not passinspection if:
.The light is on when the engineis running.
.The light does not come onwhen the ignition is in ON/RUNwhile the engine is off.
.Critical emission control systemshave not been completelydiagnosed. If this happens, thevehicle would not be ready forinspection and might requireseveral days of routine drivingbefore the system is ready forinspection. This can happen ifthe 12-volt battery has recentlybeen replaced or run down, or ifthe vehicle has been recentlyserviced.
See your dealer if the vehicle willnot pass or cannot be made readyfor the test.

Trip/Fuel Menu Items
3:Press this button to scrollthrough the following menu items:
Odometer
Press3until XX km (mi)
displays. This display shows thedistance the vehicle has beendriven in either kilometers (km) ormiles (mi).
Trip Odometers
Press3until A or B displays.
This display shows the currentdistance traveled in eitherkilometers (km) or miles (mi) sincethe last reset for each trip odometer.Both trip odometers can be used atthe same time.
Each trip odometer can be reset to
zero separately by pressingVwhile
the desired trip odometer isdisplayed.
The trip odometer has a featurecalled the retro-active reset. Thiscan be used to set the trip odometerto the number of kilometers (miles)driven since the ignition was last
turned on. This can be used if thetrip odometer is not reset at thebeginning of the trip.
To u s e t h e r e t r o - a c t i v e r e s e t f e a t u r e ,
press and holdVfor at least
four seconds. The trip odometer willdisplay the number ofkilometers (km) or miles (mi) drivensince the ignition was last turned onand the vehicle was moving. Oncethe vehicle begins moving, the tripodometer will accumulate mileage.For example, if the vehicle wasdriven 8 km (5 miles) before it isstarted again, and then theretro-active reset feature isactivated, the display will show 8 km(5 miles). As the vehicle beginsmoving, the display will thenincrease to 8.1 km (5.1 miles),8.2 km (5.2 miles), etc.
If the retro-active reset feature isactivated after the vehicle is started,but before it begins moving, thedisplay will show the number ofkilometers (km) or miles (mi) thatwere driven during the last ignitioncycle.
Fuel Range
Press3until FUEL RANGE
displays. This display shows theapproximate number of remainingkilometers (km) or miles (mi) thevehicle can be driven withoutrefueling. The display will showLOW if the fuel level is low.
The fuel range estimate is based onan average of the fuel economyover recent driving history and theamount of fuel remaining in the fueltank. This estimate will change ifdriving conditions change. Forexample, if driving in traffic andmaking frequent stops, this displaymay read one number, but if thevehicle is driven on a freeway, thenumber may change even thoughthe same amount of fuel is in thefuel tank. This is because differentdriving conditions produce differentfuel economies. Generally, freewaydriving produces better fueleconomy than city driving.
If the vehicle is low on fuel, theFUEL LEVEL LOW message will bedisplayed. SeeFuel SystemMessages011 5.
