Speedometer
The speedometer shows thevehicle's speed in either kilometersper hour (km/h) or miles perhour (mph).
Odometer
The odometer shows how far thevehicle has been driven, in eitherkilometers or miles.
Trip Odometer
The trip odometer shows how farthe vehicle has been driven sincethe trip odometer was last reset.
The trip odometer is accessed andreset through the Driver InformationCenter (DIC). SeeDriverInformation Center (DIC)0121.
Tachometer
The tachometer displays the enginespeed in revolutions perminute (rpm).
Caution
If the engine is operated with the
rpm’sinthewarningareaatthe
high end of the tachometer, the
vehicle could be damaged, and
the damage would not be covered
by the vehicle warranty. Do not
operate the engine with the rpm’s
in the warning area.
Fuel Gauge
When the ignition is on, the fuelgauge shows how much fuel is leftin the fuel tank. When the indicator
nears empty, a fuel warning light willcome on. SeeLow Fuel WarningLight011 9.Thevehiclestillhasalittle fuel left, but the vehicle shouldbe fueled soon. An arrow on the fuelgauge indicates the side of thevehicle the fuel door is on.
Here are four things that someowners ask about. These arenormal and do not indicate aproblem with the fuel gauge:
.At the service station, the gaspump 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 thefuel tank was half full, but itactually took a little more or lessthan half the fuel tank's capacityto fill it.
.The indicator moves a little whileturning a corner or speeding up.
.The gauge goes back to emptywhen the ignition is turned off.

Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as

.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. SeeFuel0207.
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 are
not used to perform an EmissionsInspection/Maintenance test or toservice the vehicle may affectvehicle operation. SeeAdd-OnElectrical Equipment0211.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/RUNwith the engine not running.
.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.
