normal intensity to enhance contrast and visibility. The system
automatically “dims down” as ambient light reaches the dash-mounted

they reach nighttime operating levels. Certain displays like the message
center and the climate control unit do not change with the dimmer
control till the dash-mounted sensor senses full night conditions.

AIMING 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 (2.5
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.

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.
