Safety Belt Reminders
Driver Safety Belt Reminder Light
There is a driver safety belt reminder light on the instrument cluster.
When the vehicle is started this light flashes and a chime comes on to remind drivers to fasten their safety belts. Then the light stays on solid until the belt is buckled. This cycle may continue several times if the driver remains or becomes unbuckled while the vehicle is moving.
If the driver safety belt is buckled, neither the light nor the chime comes on.
Passenger Safety Belt Reminder Light
There is a passenger safety belt reminder light near the passenger airbag status indicator.
When the vehicle is started this light flashes and a chime may come on to remind the front passenger to fasten their safety belt. Then the light stays on solid until the belt is buckled. This cycle may continue several times if the passenger remains or becomes unbuckled while the vehicle is moving.
If the front passenger safety belt is buckled, neither the chime nor the light comes on.
The front passenger safety belt reminder light and chime may turn on if an object is put on the seat such as a briefcase, handbag, grocery bag, laptop, or other electronic device. To turn off the reminder light and/or chime, remove the object from the seat or buckle the safety belt.
Airbag Readiness Light
This light shows if there is an electrical problem with the airbag system. The system check includes the airbag sensor(s), the passenger sensing system, the pretensioners, the airbag modules, the wiring, and the crash sensing and diagnostic module.
The airbag readiness light comes on for several seconds when the vehicle is started. If the light does not come on then, have it fixed immediately.
Warning
If the airbag readiness light stays on after the vehicle is started or comes on while driving, it means the airbag system might not be working properly. The airbags in the vehicle might not inflate in a crash, or they could even inflate without a crash. To help avoid injury, have the vehicle serviced right away.
If there is a problem with the airbag system, a Driver Information Center (DIC) message may also come on.
Passenger Airbag Status Indicator
The vehicle has a passenger sensing system. The passenger
airbag status indicator is in the overhead console.
United States
Canada
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 either the on or off symbol to let Do 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 passenger 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. See your dealer for service.
Warning
If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness including important safety information.
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 or is flashing, the Driver Information
The Center (DIC) also displays a message.
See Battery Voltage and Charging Messages
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 (Check Engine Light)
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.
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.
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’s ability to pass an Emissions Inspection/Maintenance test. See Accessories and Modifications.
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.
- Reduce vehicle speed.
- Avoid hard accelerations.
- Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being hauled as soon as it is possible. 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:
- Make sure the capless funnel adapter is removed, if fuel has been added to the vehicle using the capless funnel adapter. See
“Filling the Tank with a Portable Gas Can” under Filling the Tank 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 occur, change the fuel brand used. It may require at least one full tank of the proper fuel to turn the light off.
If none of the above has 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 to the left of the steering wheel.
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 the proper operation of the malfunctioning 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.
Brake System Warning Light
The vehicle brake system consists of two hydraulic circuits. If one of the circuits is not working, the remaining circuit can still work to stop the vehicle. For normal braking performance, both circuits need to be working.
If the warning light comes on, there is a brake problem. Have the brake system inspected right away.
This light should come on briefly when the engine is started. If it does not come on then, have it fixed so it will be ready to warn you if there is a problem.
If the light comes on and stays on, there is a brake problem.
Warning
The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service.
Electric Parking Brake Light
This light comes on when the parking brake is applied. If the light continues flashing after the parking brake is released, or while driving, there is a problem with the Electric Parking Brake system or another system. A message may also be displayed in the Driver Information Center (DIC).
If the light does not come on or remains flashing, see your dealer.
Service Electric Parking Brake Light
On some vehicles, the service electric parking brake light should come on briefly when the vehicle is in ON/RUN. If it does not come on, have it fixed so it will be ready to warn if there is a problem.
For vehicles with the reconfigurable cluster, this light may not come on when the vehicle is in ON/RUN.
If this light comes on and stays on, there is a problem with the system on the vehicle that is causing the parking brake system to work at a reduced level. The vehicle can still be driven but should be taken to a dealer as soon as possible.
Antilock Brake System (ABS) Warning Light
This light comes on briefly when the engine is started.
If the light does not come on, have it fixed so it will be ready to warn if there is a problem.
If the light comes on while driving, stop as soon as it is safely possible and turn off the vehicle. Then start the engine again to reset the system. If the ABS light stays on or comes on again while driving, the vehicle needs service. A chime may also sound when the light comes on steady.
If the ABS light is the only light on, the vehicle has regular brakes, but the antilock brakes are not functioning.
If both the ABS and the brake system warning light are on, the vehicle’s antilock brakes are not functioning and there is a problem with the regular brakes. See your dealer for service.
