Appearing in 2002 in Dark Blue and Bamboo Green, the Volvo S40 offers a few package options, which include a power driver's seat, power sunroof, leather upholstery and an emergency boot release. The 2002 Volvo S40 also provides you with a theft-proof system for your car radio to prevent unauthorised users from operating it. Resetting your radio, when it locks, will take just a few minutes of your time.

Skill level:


  1. 1

    Obtain the four-digit radio code that came with your 2002 Volvo S40 at purchase. This radio code is on a card that looks like a credit card. When you turn the radio on, the radio display will show "Input CODE ****."

  2. 2

    Contact your local Volvo dealer if you cannot find your four-digit antitheft code for the radio. The dealer can find it in a database. You may need to drive to the dealer so they can cross-reference your radio's serial number. Make sure you bring proof of ownership, such as vehicle registration and your driver's license. (See Reference 2)

  3. 3

    Rotate the "1-20/Disc" knob on the radio to select the first digit of the four-digit code.

  4. 4

    Push the knob to enter your selected number. Rotate the knob and push it in to select each of the remaining digits of the code.

  1. 1

    Re-enter the correct radio code from the beginning if you enter an incorrect code. An "Error" message will display on the screen if you make a mistake. Your radio will lock for two hours, displaying the message "Off," if you make three errors trying to enter the code.

  2. 2

    Re-input the code after two hours. The headlights must be turned off, and the ignition key turned to the first position, "I>L1" during the two-hour wait.

  3. 3

    Store the four-digit radio code in a safe location. Do not keep the radio code inside of your car.

Tips and warnings

  • You must reset your radio antitheft code whenever you disconnect your car's battery. You must also reset the radio code if you pull up the yellow fuse holder to remove a blown fuse.
