Safety belt
Reminds you to fasten your safety belt. A Belt-Minder® chime
will also sound to remind you to fasten your safety belt.
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, the “service 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 the “service engine soon” light blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for inspection/maintenance (I/M) testingin theFuel and
Refuelingchapter.
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 theFuel and Refuelingchapter. 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.
WARNING: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.
Speed control (if equipped) (RTT)
The speed control system indicator light changes color to
indicate what mode the system is in:
•On (white light): Illuminates when the speed control system is turned
on. Turns off when the speed control system is turned off.
•Engaged (green light): Illuminates when the speed control system is
engaged. Turns off when the speed control system is disengaged.

Readiness for Inspection/Maintenance (I/M) Testing
Some state, provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. SeeOn-board
Diagnostics (OBD-II)in this chapter.
Your vehicle may not pass the I/M test if the service engine soon
indicator is on or not working properly (bulb is burned out), or if the
OBD-II system has determined that some of the emission control systems
have not been properly checked. In this case, the vehicle is considered
not ready for I/M testing.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine soon
indicator blinks eight times, it means that the vehicle is not ready for I/M
testing; if the service engine soon indicator stays on solid, it means that
the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway or highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once the
engine is started, do not turn off the engine until the above driving cycle
is complete. If the vehicle is still not ready for I/M testing, the above
driving cycle will have to be repeated.

6. Replace the air filter housing cover and secure
the clamps. Be sure that the air cleaner cover tabs
are engaged into the slots of the air cleaner housing.
ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.
Vertical Aim Adjustment
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
•(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
(2.4 meter) horizontal reference line
on the vertical wall or screen at this
height (a piece of masking tape works well). The center of the lamp is
marked bya3millimeter circle on the headlamp lens.
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.

On the wall or screen you will
observe a flat zone of high intensity
light located at the top of the right
hand portion of the beam pattern. If
the top edge of the high intensity
light zone is not at the horizontal
reference line, the headlamp will
need to be adjusted.
4. Locate the vertical adjuster on
each headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in
order to adjust the vertical aim of
the headlamp. The horizontal edge of
the brighter light should touch the
horizontal reference line.
5. Close the hood and turn off the
lamps.
HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NOT ADJUSTABLE.
CHANGING A BULB
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.
These are examples of acceptable condensation:
•Presence of thin mist (no streaks, drip marks or droplets).
•Fine mist covers less than 50% of the lens.

These are examples of unacceptable moisture (usually caused by a lamp
water leak):
•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 HID headlamp bulbs
The headlamps on your vehicle use a “high intensity discharge” source.
These lamps operate at a high voltage. When the bulb is burned out, the
bulb assembly must be replaced by your authorized dealer.
Replacing front parking lamp/turn signal/sidemarker bulbs
Your vehicle is equipped with an LED front parking lamp/turn
signal/sidemarker bulbs. It is designed to last the life of the vehicle. If
replacement is required, it is recommended that you see your authorized
dealer.
Replacing fog lamp bulbs
1. Make sure the fog lamp switch is in the off position.
2. Rotate the harness/bulb assembly counterclockwise, to remove from
the fog lamp.
3. Carefully disconnect the bulb from
the harness assembly via the two
snap clips.
Install the new bulb(s) in reverse order.
