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, have the
respective system inspected immediately.
Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb. Solid illumination after the engine is started indicates the On
Board Diagnostics System (OBD-II) has detected a malfunction. Refer to
On board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.

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.
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
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 and an
“E” for Europe to assure 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.
