Frequently Asked Questions
What is a lateral acceleration sensor?
It measures the side-to-side forces on the vehicle during turns. The electronic stability control system uses this data to detect and correct skids or oversteer and understeer conditions.
Where is the lateral acceleration sensor located?
It is usually mounted near the center of the vehicle, often under the center console or on the floor tunnel, to get the most accurate reading of vehicle lateral movement.
Can I drive without stability control?
You can drive, but the vehicle will not have electronic assistance to correct skids or loss of traction. Exercise extra caution in wet, icy, or emergency maneuvering situations.
