Headlamp Aiming

The optical headlamp aiming system has been preset
at the factory and should need no further adjustment
However, If the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may
be necessary.
If oncoming vehicles flash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to
be re-aimed. It is possible however, to re-aim the
headlamps as described.
The vehicle should:
•
Be placed so the headlamps are 25 ft. (7.6 m)
from a light colored wall.
•
Have all four tires on a perfectly level surface
which is level all the way to the wall.
•
Be placed so it is perpendicular to the wall.
•
Not have any snow, ice, or mud on it.
•
Be fully assembled and all other work stopped
while headlamp aiming is being done.
•
Have a full tank of fuel and one person or
160 lbs (75 kg) on the driver seat.
•
Have all tires properly inflated.
Headlamp aiming is done with the vehicle's low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
