Hyundai i-30: Air Conditioning System / Photo Sensor
Description and operation
The photo sensor is located at the center of the defrost nozzles.
The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The
solar radiation received by its light receiving portion, generates an electromotive
force in proportion to the amount of radiation received which is transferred
to the automatic temperature control module so that the solar radiation compensation
will be performed.

Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get
to know your trailer. Acquaint yourself
with the feel of handling and
braking with the added weight of the
trailer. And always keep in mind that
the vehicle you are driving is now
longer and not nearly as responsive
as your vehicle is by itself...
The severe weather conditions of
winter quickly wear out tyres and
cause other problems. To minimise
