Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in an accident,
the headlamp aim may be affected. Aim adjustment to
the low-beam headlamps may be necessary if it is
difficult to see the lane markers (for horizontal aim),
or if oncoming drivers ash their high-beam headlamps
at you (for vertical aim).
If you believe your headlamps need to be re-aimed,
it is recommend that you take the vehicle to your dealer
for service. Jumper Cable Removal

air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
