5. If Model S is equipped with a coil suspension system, you can adjust the angle of the
headlights to accommodate the load you are carrying. You may need to lower the angle of the
headlights to avoid blinding oncoming drivers in situations when you are carrying a significant
amount of weight in the rear trunk. After touching LEVEL, drag the slider to the desired
position:
Headlights are not lowered. No change is needed when all front and rear seats are
0
occupied and only the front trunk is laden.
Headlights are lowered one level. Suitable when the front and rear seats are
1
occupied and the rear trunk is laden.
2 Headlights are lowered two levels. Suitable when carrying heavy loads.
Note: Headlight adjustments are not available if Model S is equipped with Smart Air
Suspension because Model S levels automatically.
6. Exterior lights (headlights, tail lights, side marker lights, parking lights, and license plate
lights) are set to AUTO each time you start Model S.
AUTO
Touch one of these options to temporarily change the exterior light setting:
OFF
Note: Model S has a series of lights along the lower rim of the headlights, also referred to as
"signature" lights. These lights automatically turn on whenever Model S is powered on and a
driving gear is engaged.
Warning: Always ensure that your headlamps are switched to AUTO or ON, as
appropriate, during all low visibility conditions. Failure to do so may result in a collision.
Driving
Exterior lights automatically turn on when driving in low lighting
conditions. If you change to a different setting, lights always revert to this
AUTO setting on your next drive.
Exterior lights turn off until you manually turn them back on or until the
next time you drive Model S. If daytime running lights are required in your
region, the exterior lights used for this purpose do not turn off.
Only the side marker lights, parking lights, tail lights and license plate
lights turn on.
Exterior lights turn on.
