118

If the vehicle's powertrain system or its battery has
just been serviced, the on-board diagnostics system
is reset to a ªnot ready for I/M testº condition. To
ready the on-board diagnostics system for I/M
testing, a minimum of 30 minutes of city and
highway driving is necessary as described below:
²First, at least 10 minutes of driving on an
expressway or highway.
²Next, at least 20 minutes driving in stop-and-go,
city-type traffic with at least four 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 started, do not turn off the engine until the
above driving cycle is complete.

extended period of time, contaminants may enter
the lamp housings and affect performance.

Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully
and keep out of children's reach. Grasp the
bulb only by its plastic base and do not touch the
glass. The oil from your hand could cause the bulb
to break the next time the headlamps are
operated.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position,
then open the hood.
2. At the back of the
headlamp, pull two
retainer pins up to
release the headlamp
assembly.
3. Pull headlamp
assembly forward
disengaging the lamp
from the rear hidden snap retainers to expose the
back of the bulb.
4. Release clip and
disconnect the
electrical connector
from the bulb.
5. Remove the bulb
retaining ring by
rotating it
counterclockwise
(when viewed from the
rear) about
1¤4turn to
free it from the bulb socket, and slide the ring off
the plastic base. Keep the ring to retain the new
bulb.
6. Without turning, remove the old bulb from the
lamp assembly by gently pulling it straight out of the
lamp assembly.
Maintenance and care
171

To install the new bulb:
1. With the flat side of
the new bulb's plastic
base facing upward,
insert the glass end of
the bulb into the lamp
assembly. You may
need to turn the bulb left or right to align the
grooves in the plastic base with the tabs in the lamp
assembly. When the grooves are aligned, push the
bulb into the lamp assembly until the plastic base
contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base
until it contacts the rear of the socket by rotating
clockwise until you feel a ªstop.º
3. Connect the electrical connector into the plastic
base until it snaps, locking it into position.
4. Install the headlamp on vehicle by aligning the
lamp with the rear snap retainers, push to seat and
secure with two retainer pins.
5. Turn the headlamps on and make sure they work
properly. If the headlamp was correctly aligned
before you changed the bulb, you should not need to
align it again.
Replacing front parking lamp/turn signal bulbs
1. Make sure the headlamp control is in the OFF
position.
2. Open the hood.
3. At the back of the
headlamp, pull two
retainer pins up to
release the headlamp
assembly.
4. Pull headlamp
assembly forward
disengaging the lamp
from the rear snap retainers to expose the back of
the bulb.

AIMING THE HEADLAMPS
The alignment of your headlamps should be checked
if:
²Oncoming motorists frequently signal you to
deactivate your high beams, and your high beams
are not activated.
²The headlamps do not seem to provide enough
light for clear night vision.
²The headlamp beams are pointed substantially
away from a slightly down and to the right
position.
Maintenance and care

Vertical aim adjustment
1. Park the vehicle on
a level surface
approximately 7.6
meters (25 feet) from
a vertical wall or
screen directly in front
of it.
2. Measure the height
from the center of your
headlamp to the
ground and mark an
2.4 meters (8 foot)
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 by a 3.0 mm
circle on the headlamp lens.
3. Turn on the low beam headlamps to illuminate the
wall or screen and open the hood.
4. On the wall or screen you will observe a distinct
line of high intensity light. If this is not centered on
the horizontal reference line, the beam will need to
be adjusted.
5. Locate the vertical adjuster on each headlamp,
then usea6mmwrench or screwdriver to turn the
adjuster either counterclockwise (to adjust up) or
clockwise (to adjust down) centering the light on
the horizontal reference line.
6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS
VEHICLE AND IS NON-ADJUSTABLE.
7. Close the hood and turn off the lamps.
