On all EX class models, the car radio included in the standard package is equipped with an alarm system. After turning off the power, the radio can only be put into operation by dialing a 5-digit code, which is given to the owner at the time of purchase of the car. Even if the power was turned off only for a moment, the audio equipment will not function without entering the code. Without verifying the security code data, do not disconnect the battery, do not remove the No. 9 fuse (for 20 A) from the mounting block located in the engine compartment. More complete information on the security system of the audio equipment is set out in the service book included with the car.
To unlock the audio equipment, turn on its power: the display will show "CODE". Using the radio station selection buttons, enter the required 5-digit security code: the radio should beep. 10 attempts are given to enter the correct combination. After the code is entered correctly, the inscription "CODE" should disappear from the radio display. The introduction of your favorite radio stations into the memory of the receiver will have to be done again.
