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.
Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the enginecoolant temperature.
It also provides an indicator of howhard the vehicle is working. During amajority of the operation, the gaugewill read 100 °C (210 °F) or less.If the vehicle is pulling a load orgoing up hills, it is normal for thetemperature to fluctuate andapproach the 122 °C (250 °F) mark.If the gauge reaches the 125 °C(260 °F) mark, it indicates that thecooling system is working beyondits capacity.
SeeEngine Overheating0230.

Voltmeter Gauge
When the engine is not running, butthe ignition is on, this gauge showsthe battery's state of charge inDC volts.
When the engine is running, thegauge shows the condition of thecharging system. Readings betweenthe low and high warning zonesindicate the normal operating range.
Readings in the low warning zonemay occur when a large number ofelectrical accessories are operatingin the vehicle and the engine is leftat an idle for an extended period.This condition is normal since the
charging 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 be only driven for ashort time with the reading in eitherwarning zone. If it must be driven,turn off all unnecessaryaccessories.
Readings in either warning zoneindicate a possible problem in theelectrical system. Have the vehicleserviced as soon as possible.

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

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.
