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.

|
3. |
Emit intensive light toward the photo sensor using a lamp, and check
the output voltage change.
|

To equalize tread wear, HYUNDAI
recommends that the tyres be rotated
every 7,500 miles (12,000 km) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage...
ALWAYS use the Floor Mat Anchors
to attach the front floor mats to the
vehicle. The anchors on the front
floor carpet keep the floor mats from
