Blind Spot Information (BLIS)* limitations

Blind Spot Information functionality may be reduced in certain situations.

Updated 08/06/2023

Dirt, ice and snow on the sensors may reduce functionality and prevent the system from providing warnings.
Do not attach any objects, tape, decals, etc., on the surface of the sensors.
BLIS is deactivated if a trailer is attached to the vehicle's electrical system.

Maintenance

The BLIS/CTA1 sensors are located on the inside of the rear fenders/bumper.

For the system to function optimally, the area over and around the sensors must be kept clean.
