ble for controlling the headlights and may
need to switch them on and off manually
depending on light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions

and when driving in the dark.

for a while, the parking light may switch off
automatically. Avoid using the parking
lights for several hours.

is responsible for adhering to any local ap-
plicable regulations while driving and when
parking the vehicle.

daytime running lights are switched on*. In
vehicles in certain markets, the tail lights
will also turn on.
—Incool or damp weather, the inside of the
headlights, turn signals, and tail lights can
fog
over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This
