Note:If the battery is disconnected, discharged, or a new battery is
installed, the dimmer control requires re-calibration. Press the dimmer
control from the full dim position to the full on position to reset. This
will ensure that your displays are visible under all lighting 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
(2.4 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.

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.

Replacing interior bulbs
Check the operation of all bulbs frequently.
Replacing exterior bulbs
Check the operation of all bulbs frequently.
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
1. Make sure headlamp switch is in the off position, then open the hood.
