When the ignition is on, the fuel gauge indicates about how much fuel is left in the tank. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. When the indicator nears empty, the low fuel light comes on. There is still a little fuel left, but the fuel tank should be filled soon. Here are four things that some owners ask about. None of these show a problem with the fuel gauge: . At the service station, the fuel

pump shuts off before the gauge reads full. It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. The gauge moves a little while turning a corner or speeding up.

When the vehicle is started, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF,

or the on or off symbol, to let you know the status of the front outboard passenger frontal airbag. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the front outboard passenger frontal airbag is allowed to inflate. If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the front outboard passenger frontal airbag. If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system.

Charging System Light

The charging system light comes on briefly when the ignition is turned on, but the engine is not running, as a check to show the light is working. It should go out when the engine is started.

If the light stays on or comes on while driving, there may be a problem with the electrical charging system. Have it checked by your dealer. Driving while this light is on could drain the battery. When this light comes on, the Driver Information Center (DIC) also displays a message. See Battery Voltage and Charging Messages on page 5-34. If a short distance must be driven with the light on, be sure to turn off all accessories, such as the radio and air conditioner.

Malfunction Indicator Lamp A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors the operation of the vehicle to ensure emissions are at acceptable levels, helping to maintain a clean environment. The malfunction indicator lamp comes on when the vehicle is placed in

Service Only Mode, as a check to show it is working. If it does not, have the vehicle serviced by your dealer. See Ignition Positions on page 9-19.

If the malfunction indicator lamp comes on while the engine is running, this indicates that there is an OBD II problem and diagnosis and service might be required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system also assists the service technician in correctly diagnosing any malfunction.

This light comes on during a malfunction in one of two ways: Light Flashing: A misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Diagnosis and service might be required. To prevent more serious damage to the vehicle: . Reduce vehicle speed. . Avoid hard accelerations. . Avoid steep uphill grades.

If the light continues to flash, stop and park the vehicle. Turn the vehicle off, wait at least 10 seconds, and restart the engine. If the light is still flashing, follow the previous steps and see your dealer for service as soon as possible. Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. The following may correct an emission control system malfunction:

If fuel has been added to the vehicle using the capless funnel adapter, make sure the capless funnel adapter is removed. See “Filling the Tank with a Portable Gas Can” under Filling the Tank on page 9-55. The diagnostic system can detect if the adapter has been left installed in the vehicle, allowing fuel to evaporate into the atmosphere.

A few driving trips with the adapter removed should turn off the light.

. Check that good quality fuel is used. Poor fuel quality causes the engine not to run as efficiently as designed and may cause stalling after start-up, stalling when the vehicle is changed into gear, misfiring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up. If one or more of these conditions occurs, change the fuel brand used. It may require at least one full tank of the proper fuel to turn the light off. See Fuel on page 9-53. If none of the above have made the light turn off, your dealer can check the vehicle. The dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that might have developed.

Emissions Inspection and Maintenance Programs Depending on where you live, your vehicle may be required to participate in an emission control system inspection and maintenance program. For the inspection, the emission system test equipment will likely connect to the vehicle's Data Link Connector (DLC).

The DLC is under the instrument panel near the hood release. See your dealer if assistance is needed. The vehicle may not pass inspection if:

The malfunction indicator lamp is on with the engine running, or if the vehicle is placed in Service Only Mode and the malfunction

indicator lamp does not come on. See your dealer for assistance in verifying proper operation of the malfunction indicator lamp. The OBD II (On-Board Diagnostics) system determines that critical emission control systems have not been completely diagnosed. The vehicle would be considered not ready for inspection. This can happen if the 12-volt battery has recently been replaced or run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer can prepare the vehicle for inspection.
