132 Instruments and Controls
When the ignition is on, the fuelgauge indicates about how muchfuel is left in the tank.
There is an arrow near the fuelgauge pointing to the side of thevehicle the fuel door is on.
When the indicator nears empty, thelow fuel light comes on. There still isalittlefuelleft,butthevehicleshould be refueled soon.
Here are four things that someowners ask about. None of theseshow a problem with the fuel gauge:
.At the service station, the fuelpump shuts off before the gaugereads full.
.It takes a little more or less fuelto fill up than the 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 takes a few secondsto stabilize after the ignition isturned on, and goes back toempty when the ignition isturned off.
Engine Oil Pressure
Gauge
Metric
English
The engine oil pressure gaugeshows the engine oil pressurein kPa (kilopascals) or psi (poundsper square inch) when the engine isrunning.
Oil pressure can vary with enginespeed, outside temperature, coolanttemperature, and oil viscosity.

Instruments and Controls 133
Areadingoutsidethenormaloperating range can be caused by adangerously low oil level or someother problem causing low oilpressure. Check the vehicle's oil assoon as possible. See“OILPRESSURE LOW STOP ENGINE”underEngine Oil Messages0152andEngine Oil0359.
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
Engine Coolant
Temperature Gauge
Metric
English
This gauge measures thetemperature of the vehicle's enginecoolant.
While driving under normaloperating conditions, if the needlemoves into the red warning area,the engine is too hot. Pull off theroad, stop the vehicle, and turn offthe engine as soon as possible.

Voltmeter Gauge
When the ignition is on, this gaugeindicates the battery voltage.
When the engine is running, thisgauge shows the condition of thecharging system. The gauge cantransition from a higher to lower or alower to higher reading. This isnormal. If the vehicle is operatingoutside the normal operating range,the charging system light comes on.SeeCharging System Light0138for more information. The voltmetergauge may also read lower when infuel economy mode. This is normal.
Readings outside the normaloperating range can also occurwhen a large number of electricalaccessories are operating in thevehicle and the engine is left idlingfor an extended period. Thiscondition is normal since thecharging system is not able toprovide full power at engine idle. Asengine speeds are increased, thiscondition should correct itself ashigher engine speeds allow thecharging system to create maximumpower.
The vehicle can only be driven for ashort time with the readings outsidethe normal operating range. If thevehicle must be driven, turn off allaccessories, such as the radio andair conditioner.
Readings outside the normaloperating range indicate a possibleproblem in the electrical system.Have the vehicle serviced as soonas possible.

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. SeeIgnitionPositions0268.
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.

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:
.If fuel has been added to thevehicle using the capless funneladapter, make sure that it hasbeen removed. See“Filling theTa n k w i t h a P o r t a b l e G a s C a n”underFilling the Tank0313.The diagnostic system candetect if the adapter has beenleft installed in the vehicle,allowing fuel to evaporate intothe atmosphere. A few drivingtrips with the adapter removedmay turn off the light.
.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 atleast one full tank of the properfuel to turn the light off. SeeFuel0311.
If the light remains on, see yourdealer.
