WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive 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
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Service engine soon:TheService
engine soonindicator 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 soon
light 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 theReadiness for Inspection/Maintenance
(I/M) testingin theMaintenance 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
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.

start up or while driving, the tire
pressure should be checked. Refer
toInflating your tiresin theTires, Wheels and Loadingchapter. When
the ignition is first turned to ON, the light will illuminate for 3 seconds to
ensure the bulb is working. If the light does not turn ON or begins to
flash, have the system inspected by your authorized dealer. For more
information on this system, refer toTire pressure monitoring systemin
theTires, Wheels and Loadingchapter.
Speed control:Illuminates when
the speed control is engaged. Turns
off when the speed control system
is disengaged.

•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
2. Measure the height of the
headlamp bulb center from the
ground and mark an 8 foot (2.5
meter) horizontal reference line on
the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.
To see a clearer light pattern for adjusting, you may want to block the
light from one headlamp while adjusting the other.
4. On the wall or screen you will
observe an area of high intensity
light. The top of the high intensity
area should touch the horizontal
reference line, if not, the beam will
need to be adjusted using the next
step.
5. Locate the vertical adjuster on
each headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise (to adjust down) or
counterclockwise (to adjust up).
The horizontal edge of the brighter
light should touch the horizontal
reference line.
6. Close the hood and turn off the
lamps.

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 and an
“E” for Europe 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.
