WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Note:Some Warning Lights are reconfigurable telltale (RTT) indicator
lights and will illuminate in the Message Center Display and function the
same as the warning light.
Service engine soon:The
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance (I/M)
testing. Normally, theService engine soonlight will stay on until the
engine is cranked, then turn itself off if no malfunctions are present.
However, if after 15 seconds theService engine soonlight blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for Inspection/Maintenance (I/M) testingin the
Maintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could

BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America to ensure
lamp performance, light brightness and pattern and safe visibility. The
correct bulbs will not damage the lamp assembly or void the lamp
assembly warranty and will provide quality bulb burn time.
