Table of contents: Locking and unlocking the car ↓ Synchronization of codes ↓
The remote control system allows you to use the central lock, turn the security alarm on and off without using a regular key, using an infrared emitter.

The infrared emitter and batteries are mounted in the handle of the car key. The infrared sensors are located in the pillars of both front doors.

The contour of the remote control area is the same on both sides of the car. The maximum range depends on various conditions and ranges from 2 to 4 m. As the batteries discharge, it decreases. The range also decreases when the sensors are dirty.

Locking and unlocking the car



While in the remote control range, point the remote control towards the sensor and press the emitter button without holding it for too long (see arrow). In this case, the central lock will lock the car and the security alarm will be activated or the system will perform the opposite action.

Note: If the vehicle has not been used for approximately 7 days (the locks were not turned on or off), then the infrared signal receiver will automatically turn off to avoid draining the battery.


To activate the infrared sensor, you need to press the button on the remote control and then open the driver's or passenger's door with the key.

Synchronization of codes



If the car door locks do not unlock when you press the remote control button, the reason for this may be a mismatch of codes on the remote control and on the central lock control unit. This can happen if you frequently use the transmitter button outside the system's coverage area.



Synchronization of exchange codes is performed automatically if the driver's or passenger's door is opened with the key within one minute after an unsuccessful attempt to open the locks using the remote control.
