2021 LINCOLN NAUTILUS low beam

After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time your vehicle must remain fully
locked with the ignition off.
Note:
If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
Battery Disposal Make sure that you dispose of old
batteries in an environmentally
friendly way. Seek advice from
your local authority about recycling old
batteries. ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are properly
aimed at the assembly plant. If your vehicle
has been involved in a crash, have the aim
of the headlamp beam checked by an
authorized dealer.

from one headlamp while adjusting the
other.
