GMC Terrain: Detecting the Vehicle Ahead - Forward Collision Alert (FCA) System - Object Detection Systems - Driving and Operating - GMC Terrain Owner's ManualGMC Terrain: Detecting the Vehicle Ahead

The green vehicle ahead indicator will appear when a vehicle is detected ahead.

The green vehicle ahead indicator will appear when a vehicle is detected ahead. Whenever this indicator does not appear, FCA will not respond. The indicator may disappear on curves, highway exit ramps, or hills, or due to poor visibility. The FCA system will not detect another vehicle ahead until it is completely in the driving lane.

WARNING

If the FCA camera sensor is blocked by dirt, snow, or ice, or if the windshield is damaged, it may not detect a vehicle ahead. FCA may not help avoid a collision under these conditions. Do not rely on FCA when the camera is blocked by snow, ice, or dirt. Keep the windshield clean.

WARNING

If the headlamps are not cleaned or properly aimed, the FCA system may not detect a vehicle ahead. FCA may not help avoid a collision under these conditions. Keep the headlamps clean and properly aimed.

Unnecessary Alerts

FCA may sometimes set unnecessary alerts to turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service.

Other Messages

There are messages that may appear on the Driver Information Center (DIC) in the instrument cluster to provide information about FCA. See Object Detection System Messages on page 5‑29.

Cleaning the System

If the FCA system does not seem to operate properly, clean the outside of the windshield area in front of the camera sensor before considering taking the vehicle in for service.
