Manual Headlamp Aiming Procedure
CAUTION
The following procedure
is
not a substitute for having
the head
lamps professionally aligned
by
a certified
headlamp alignment professional to the Society of
Automobile Engineering standards.
Improper head-
lamp alignment
may result
in
poor visibility during
reduced
light conditions
and
may result
in
an
accident.
1. Ensure your vehicle is loaded to your spe-
cific "travel and camping" conditions.
2. Remove all snow, ice,
ditt and other debris
that may affect the ride height
of
the vehicle.
3. Find a flat area at least the length
of
your
motorhome plus 7.62 meters (25 ft) with a
vertical flat sUlface that is at least
3.0 m
(10
ft)
by
3.0 (10 ft) at one end (a driveway
and garage door could be used).
4. Measure 7.62 m
(25
ft) and position the
motor home so the headlamps are 7.62 m
from the vertical flat surface and secure by
05-20
On The Road
placing in park or Neutral and setting the
parking brakes.
5. Inspect your headlamp system and
deter-
mine
if
it is a "Type 1" or "Type 2" system.
A Type
I system has a separate HI and
LOW beam and uses four lamps. A Type 2
system can be identified
by
locating the
number
"2" embossed on the lens
of
the
lamp.
6. Measure the height from the ground to the
center
of
the low beam filament
of
the dri-
ver's side headlamp. Project this height in
an exact straight line to the vertical surface
7.62 m away from the motor home. Mark
the height
of
the filament and center line
on the vertical sUlface. This will have set
up a
"coordinate system" for protecting the
headlamp's beam on the vertical surface.
7. Repeat step 5 for the passenger's side
headlamp.
8. Activate the headlamp system.
Using
Figure I below the projected beam on the
vertical surface is to be located
as
follows.
