Warning: The Data Link Connector (DLC) is used for vehicle service and Emission Inspection/Maintenance testing. See Malfunction Indicator Lamp (Check Engine Light). A device connected to the DLC - such as an aftermarket fleet or driver-behavior tracking device - may interfere with vehicle systems. This could affect vehicle operation and cause a crash.

Such devices may also access information stored in the vehicle's systems.

Caution: Some electrical equipment can damage the vehicle or cause components to not work and would not be covered by the vehicle warranty. Always check with your dealer before adding electrical equipment.

Add-on equipment can drain the vehicle's 12-volt battery, even if the vehicle is not operating.
