AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed before leaving the
assembly plant. If your vehicle is involved in an accident or if you have
problems fixing the alignment of your headlamps, have them checked by
a qualified service technician.
Headlamp aim adjustment
The headlamps on your vehicle can only be vertically adjusted. Your
vehicle does not require horizontal aim adjustments.
To adjust the headlamps:
1. Park your vehicle on a level
surface about 7.6 meters (25 feet)
away from a vertical plain surface
(3). Check your headlamp alignment
at night or in a dark area so that
you can see the headlamp beam
pattern.
•(1) Eight feet
•(2) Center height of lamp to
ground
•(3) Twenty-five feet
•(4) Horizontal reference line
2. The center of the headlamp has a 3.0 mm circle on the lens. Measure
the height from the center of your headlamp to the ground (2) and mark
a 2.4 meter (8 foot) long horizontal line on the plain surface (1) at this
height (masking tape works well).
3. Turn on the low beam headlamps.
The brightest part of the light
should be below the horizontal line
(4). If it is above the line the
headlamp will need to be adjusted.
4. Open the hood.

Cargo/reading lamps
The dome portion of the lamp or
the center light can be turned on
when the headlamp control is
rotated fully up or when a door is
opened.
With the ignition in the ACC or ON position, the rear dome lamp can be
turned ON or OFF by sliding the control.
BULBS
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
Replacing the interior bulbs
Check the operation of the bulbs frequently. To replace any of the
interior bulbs, see a dealer or qualified technician.
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 assure lamp performance, light brightness and pattern
and safe visibility. Using incorrect bulbs may damage the lamp assembly
or void the lamp assembly warranty or may not provide quality bulb burn
time.
