How to Disable the Seat Belt Alarm on a Mitsubishi Lancer

by William Jackson

The Lancer is a sedan, manufactured by Mitsubishi, that has been produced on and off since 2006. The Lancer features a computerized safety system to prevent accident or injury, including a seat belt alarm that reminds both driver and passenger to put on their seat belts. This alarm is activated when the system senses a certain amount of weight on the given seat. If your alarm is going off when you'd rather it didn't, there are a few steps you can take to turn it off.

Step 1

Empty anything off the seat that might cause the sensors to indicate that a passenger is in the seat. Place heavy objects on the back seat, the floor or in the trunk, which may also be safer while you're traveling.

Step 2

Pull the seat belt across the seat, or wrap the belt around the back of the seat, and snap the buckle into the clip. Once the seat belt is buckled, the sensors should stop the alarm.

Consider taking your car in to be repaired if the sensors are going off when they shouldn't be. It is not safe to try to tamper with this system on your own since it is a part of a larger, more complex, computerized system and you may do more harm than good.


  • Consider obtaining a spare seat belt buckle for a Mitsubishi Lancer from a junkyard that you can cut from the belt and keep buckled into the clip when necessary.


  • It is well-established that passengers are much safer when wearing seat belts. Seat belts and their corresponding alarms are an important part of vehicle safety and improper use of a seat belt can be dangerous.
