The system comes with 4 compact waterproof sensors that can be spray painted to color match the shade of your bumper. The parking sensors can be
configured, by a Gemini authorized Service Center, to your preference and be set up so as not to be impeded by a rear mounted spare tire/tow bar.
The system is automatically activated when ignition is turned ON and reverse gear is engaged. Two consecutive beeps will confirm activation. Detection of
obstacles will be signaled by the buzzer. The audible warning with a series of beeps will increase in pitch and frequency as the vehicle moves nearer a stationary
object: the faster the beeping the closer the obstacle. The beeps become a continuous solid tone when the preset minimum safety distance (STOP zone) is
reached.
Tow Bar/Rear Spare Tire Configuration
When a vehicle has a tow bar or a rear spare tire, the control module can be configured to push out the impact detection zone past the accessory. The control
module must be configured by an authorized Service Center.
CAUTION: OBSTACLES BETWEEN THE BUMPER AND THE NEW STOP ZONE WILL NOT BE DETECTED.
Trailer Recognition
Trailer recognition mode automatically disables the rear sensors when towing with trailer plug connected (contact an authorized Service Center). When reverse
gear is engaged, 3 Bops will confirm deactivation of all sensors.
SENSOR DETECTION INFORMATION
Certain conditions may affect the ability of the sensor to correctly detect obstacles:
1. Presence of human beings, animals or small obstacles or objects/materials with low reflectance might not be detected by the parking system.
2. In case of heavy rain or snow the parking system might give an audible alert even if no obstacles are present: this does not necessarily indicate that
the parking system is defective.
3. If the sensors are covered with mud, ice or snow (normal function resumes after cleaning or defrosting).
4. An extremely bumpy road or an incline, gravel or grass.
5. Vehicle horns, motorcycle engines, air brakes of large vehicles or other loud noises producing ultrasonic waves.
6. Heavy rain or splashes on the sensors and water puddles.
7. Obstacles located below the bumper will not be detected when they are in close proximity.
BASIC MAINTENANCE TIPS
When cleaning the sensors take special care not to scratch or damage the surface: carefully clean the sensors with a soft cloth.
In car washes which use steam jet or high-pressure washers, keep the nozzle at least 10 cm away from the sensors.
SENSOR FAILURE INDICATION
When reverse gear is engaged, the parking sensor system provides an instant, automatic, self-diagnostic function. If all the sensors are operative, 2 Beeps will
confirm activation. If one of the sensors is faulty or disconnected, a deep error tone (Bop) will sound followed by the number of beeps corresponding to the faulty
sensor. The cycle will repeat until all faulty sensors have been signaled. 2 Bops will confirm the end of the self-test cycle.
The system will exclude any faulty sensor and keep the other ones active. The following is an example of error indications:
Sensor 1 inoperative => 2 activation Beeps + 1 Bop + 1 Beep + 2 closing Bops.
Sensors 1 and 2 inoperative => 2 activation Beeps + 1 Bop + 1 Beep + 1 Bop + 2 Beeps + 2 closing Bops.

Sensors and adapters can be spray painted before assembly to match the color of the vehicle (optional). To spray paint proceed as follows:
1. Use isopropyl alcohol to clean the sensors and the adapters and let dry. Avoid touching the cleaned surfaces.
2. Insert the selected adapters in the supplied cardboard template:
Center adapters => fully insert into the cardboard template slots from the top side.
Outer adapters => press halfway down the slots, up to the side tabs, from the top side.
3. The sensors must be inserted in the central slots from underneath the cardboard. For a perfect spray-paint finish, we recommend turning down
the black silicone seal around the sensor head before inserting the sensor into the slots (paint might not adhere to the silicone).
 
4. Fold the cardbox template into a box. Spray paint the sensors and the adapters and let dry thoroughly before assembling.
NB: Too much spray paint can impair the sensors performance.
