System Lights and Messages
When the system detects a vehicle, an alert indicator illuminates in the exterior mirror on the side the approaching vehicle is coming from. If you turn the direction indicator on for that side of your vehicle, the alert indicator flashes.
Note: The system may not alert you if a vehicle quickly passes through the detection zone.
Blocked Sensors
The sensors are behind the rear bumper on both sides of your vehicle.
Note: Keep the sensors free from snow, ice and large accumulations of dirt.
Note: Do not cover the sensors with bumper stickers, repair compound or other objects.
Note: Blocked sensors could affect system performance.
If the sensors become blocked, a message could appear in the information display. The alert indicators remain illuminated but the system does not alert you.

Note: The system may not correctly operate when towing a trailer. For vehicles with an approved trailer tow module and tow bar, the system turns off when you attach a trailer. For vehicles with an aftermarket trailer tow module or tow bar, we recommend that you switch the system off when you attach a trailer.
To permanently switch the system off, contact an authorized dealer.
Each door has a backup power system which allows the door to function if your vehicle has no power. The system has a limited number of operations before the power is depleted and turns off. When the system turns off, the door remains open and unlatched and does not close.
If your vehicle has no power and the backup power system is turned off, you can close and secure your vehicle by manually resetting each door latch using a key in the position shown.
