Driving in Fog, Mist and Haze
Fog can occur with high humidity or heavy frost. It can
be
so mild that you can see through it for several
hundred feet (meters). Or it might be
so thick that you
can see only a few feet (meters) ahead. It may come
suddenly to an otherwise clear road. And it can be a
major hazard.
When you drive into a fog patch, your visibility will be
reduced quickly. The biggest dangers are striking the vehicle ahead or being struck by the one behind. Try
to
“read” the fog density down the road. If the vehicle
ahead starts to become less clear or, at night,
if the
taillights are harder to see, the fog is probably
thickening. Slow down to give traffic behind you a chance to slow down. Everybody then has a better
chance to avoid hitting the vehicle ahead.
A patch of dense fog may extend only for a few feet
(meters) or for miles (kilometers); you can’tyeally tell
while you’re in it. You can only treat the situation with
extreme care.
One common fog condition
-- sometimes called mist or
ground fog
-- can happen in weather that seems perfect,
especially at night or in the early morning in valley and
low, marshy areas. You can be suddenly enveloped
in
thick, wet haze that may even coat your windshield. You
can often spot these fog patches or mist layers with your
headlights. But sometimes they can be waiting for you
as you come over a hill or dip into a shallow valley.
Start your windshield wipers and washer, to help clear
accumulated road dirt. Slow down carefully.
Tips on Driving in Fog
If you get caught in fog, turn your headlights on low
beam, even in daytime. You’ll see
-- and be seen --
better. Use your fog lights if your vehicle has them.

Headlights
The headlight wiring is protected by a circuit breaker in
the fuseblock. An electrical overload will cause the
lights to go on and
off, or in some cases to remain off. If
this happens, have your headlight wiring checked right
away.
Windshield Wipers
. The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If
the overload is caused by some electrical problem and
not snow, etc., be sure to get
it fixed. ,
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed or goes
away.
