Alarm Range - Hyundai GENESIS COUPE BK 2010 Manual

7. Sensors may not operate correctly in the below conditions.
Ensure sensors are clean from mud or dirt.
(1) When spraying the bumper, the sensor opening is covered with something in order not to be contaminated. If
sensor opening is contaminated with mud, snow, or dirt, detection range will be reduced and alarm may not be
generated under the crash condition. Dirt accumulated on the sensor opening shall be removed with water.
Do not wipe or scrape sensor with a rod or a hard object.
(2) If the sensor is frozen, alarm may not operate until sensor thaws.
(3) If a vehicle stays under extremely hot or cold environment, the detection range may be reduced. It will be
restored at the normal temperature.
(4) When heavy cargo is loaded in trunk, it changes the vehicle balance, which reduces the detection range.
(5) When other vehicle's horn, motor cycle engine noise, or other ultra-sonic wave sources are near.
(6) Under heavy rain.
(7) When reversing towards a vertical wall and the gap between the vehicle and the wall is 15cm. (Alarm may
sound despite the absence of a barrier)
(8) If radio antenna is installed at the rear.
(9) If the vehicle rear wiring is re-routed or electrical component is added at the rear part.
(10) Vehicle balance is changed due to the replacement of the rear spring.
(11) The unit will operate normally when the vehicle speed is 5km/h or less. Above this speed, the unit may not
operate normally.
8. Check the rear bumper for installation condition and deformation. If installed improperly or the sensor orientation is
deviated, it may cause malfunction.
9. Be careful not to apply shock during sensor installation on the transmission or reception unit.
10. When adding electrical devices or modifying harness at the rear body of the vehicle, ensure not to change the
transmission and reception unit wiring. Tagging the transmission side and reception side, it may cause malfunction.
11. High power radio transmitter (above 10W) may cause malfunction. Do not install it on the vehicle.
12. Be careful that excessive heat or sharp objects shall not touch ultrasonic sensor surface.
Do not cover the sensor opening or press the sensor.

Description
When reversing, the driver is not easy to find objects in the blind spots and to determine the distance from the object.
In order to provide the driver safety and convenience, back warning system will operate upon shifting to "R" Ultrasonic
sensor will emit ultrasonic wave rearward and detect the reflected wave. Control unit will calculate distance to the object
using the sensor signal input and output buzzer alarm in three steps (first, second and third alarm).

Alarm Range

Upon detecting an object at each range out of 3 ranges as stated below within the operation range, it will generate

Second alarm : Object comes near to the sensor located at the rear of vehicle, within 41-80cm ± 10cm
Third alarm : Object comes near to the sensor located at the rear of vehicle, within 40cm ± 10cm
