Hyundai i-30: Engine Control System / Knock Sensor (KS)
Description and operation
Knocking is a phenomenon characterized by undesirable vibration and noise and
can cause engine damage. Knock Sensor (KS) is installed on the cylinder block
and senses engine knocking.
When knocking occurs, the vibration from the cylinder block is applied as pressure
to the piezoelectric element. When a knock occurs, the sensor produces voltage
signal. The ECM retards the ignition timing when knocking occurs. If the knocking
disappears after retarding the ignition timing, the ECM will advance the ignition
timing. This sequential control can improve engine power, torque and fuel economy.

Other information:
Since the sidewalls of radial tyres are
thinner than other types of tyres, they
may be damaged by mounting some
types of tyre chains on them.
Therefore, the use of snow tyres is
recommended instead of tyre chains.
Do not mount tyre chains on vehicles
equipped with aluminium wheels; if
unavoidable use a wire or fabric type
snow chain...
The vehicle’s front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly
they are designed to help protect
passengers from whiplash and other
neck and spinal injuries during an
accident, especially in a rear impact
collision...

If your vehicle is equipped with a
sunroof, you can slide or tilt your
sunroof with the sunroof control lever
located on the overhead console.
The ignition switch must be in the ON
position before you can open or
close the sunroof.
The sunroof can be operated for
approximately 30 seconds after the
ignition key is removed or turned to
the ACC or LOCK(or OFF) position.
However, if the front door is opened,
the sunroof cannot be operated even
within 30 seconds.
