bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Standard message center
Note: Some warning lights are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights.
Optional message center
Note: Some warning lights are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights. The first three
positions will only display one
warning telltale at a time; the last
three positions can cycle between
different warning telltales.
Service engine soon: The service
engine soon indicator
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, the service engine soon
indicator will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the service engine
soon indicator blinks eight times, it means that the vehicle is not ready
for I/M testing. See the Readiness for Inspection/Maintenance (I/M)
testing in the Maintenance and Specifications chapter.
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 the Maintenance 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 by your authorized dealer. Instrument Cluster

INTERIOR LAMPS
Front map lamps (if equipped)
The map lamps are located on the overhead console. Press the controls
on either side of each map lamp to turn on the lamps. The map lamps
also light when:
• any door is opened,
• the instrument panel dimmer
switch is rotated up until the
courtesy lamps come on, and
• any of the remote entry controls
are pressed and the ignition is
off.

Your vehicle may have map lamps

BULB REPLACEMENT
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
• Presence of thin mist (no streaks, drip marks or droplets)
• Fine mist covers less than 50% of the lensLights

Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
• Water puddle inside the lamp
• Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
