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 trunk release. The 2002 Volvo S40 also provides you with a theft-proof system for your car radio to prevent unauthorized users from operating it. Resetting your radio, when it locks, will take just a few minutes of your time.

Entering the Radio Code

Step 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 ****."

Step 2

Contact your local Volvo dealer if you cannot find your four-digit anti-theft 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)

Step 3

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

Step 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.

Error Entering Code

Step 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.

Step 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.
