Other information:
Description
Input speed sensor is a vital unit that measures the rate of rotation of the
input shaft inside the transaxle and delivers the readings to the TCM. The sensor
provides critical input data that's used in feedback control, damper clutch
control, gear setting control, line pressure control, clutch activation pressure
control, and sensor fault analysis...
The rear seatbacks can be folded to facilitate carrying long items or to increase
the luggage capacity of the vehicle.
WARNING
Never allow passengers to sit on top of the folded down seatback
while the vehicle is moving. This is not a proper seating position and no seat
belts are available for use...

WARNING
To reduce the risk of an air bag deploying unexpectedly and causing serious
injury or death:
Do not hit or allow any objects to impact the locations where air
bags or sensors are installed.
Do not perform maintenance on or around the air bag sensors. If
the location or angle of the sensors is altered, the air bags may deploy when
they should not or may not deploy when they should.
Installing bumper guards with nongenuine Hyundai or non-equivalent
parts may adversely affect the collision and airbag deployment performance.
Press the Engine Start/Stop button to the OFF or ACC position and
wait for 3 minutes when the vehicle is being towed to prevent inadvertent air
bag deployment.
Have all air bag repairs performed by an authorized HYUNDAI dealer.
