Wheel /tire noise, vibration and harshness concerns are directly related to
vehicle speed and are not generally affected by acceleration, coasting or decelerating.
Also, out-of-balance wheel and tires can vibrate at more than one speed. A vibration
that is affected by the engine rpm, or is eliminated by placing the transmission
in Neutral is not related to the tire and wheel. As a general rule, tire and
wheel vibrations felt in the steering wheel are related to the front tire and
wheel assemblies. Vibrations felt in the seat or floor are related to the rear
tire and wheel assemblies. This can initially isolate a concern to the front
or rear.
Careful attention must be paid to the tire and wheels. There are several symptoms
that can be caused by damaged or worn tire and wheels. Perform a careful visual
inspection of the tires and wheel assemblies. Spin the tires slowly and watch
for signs of lateral or radial runout. Refer to the tire wear chart to determine
the tire wear conditions and actions

Description and operation
Description
The auto defogging sensor is installed on the front window glass. The sensor
judges and sends signal if moisture occurs to blow out wind for defogging. The
air conditioner control module receives signal from the sensor and restrains
moisture and eliminate defog by controlling the intak
Description
•
PDW consists of 8 sensors (front : 4 units, rear : 4 units) that are
used to detect obstacles and transmit the result in three separate warning
levels, the first, second and third to IBU via LIN communication.
