Warning system sensitivity
You can change the sensitivity on the warning system to one of three settings, by using the five-way control on your steering wheel:*
- Scroll to Driver Assist > Collision Warning > Sensitivity
- Select either High, Normal or Low
The most sensitive setting will detect stationary objects near your vehicle, while a lower setting may lead to fewer and later warnings.
* If collision warnings are perceived as being too frequent or disturbing then the warning sensitivity can be reduced, though the manufacturer recommends using the highest sensitivity setting where possible. Setting lower sensitivity would lead to fewer and later system warnings.
If a “blocked sensor” message appears in your vehicle’s information display, radar signals from the sensor have been obstructed.* When this issue occurs, vehicles in front of you can’t be detected, and the collision warning system won’t function.
Here are some possible causes for this message and suggested actions to restore warning system functionality:
|The surface of the radar in the grille is dirty or obstructed in some way||Clean the grille surface in front of the radar, or remove the object causing the obstruction|
|The surface of the radar in the grille is clean, but the message remains in the display||Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed|
|Heavy rain, spray, snow, or fog is interfering with the radar signals||The collision warning system is temporarily disabled. Collision warning should automatically reactivate a short time after weather conditions improve|
|Swirling water, or snow or ice on the surface of the road may interfere with the radar signals||The collision warning system is temporarily disabled. Collision warning should automatically reactivate a short time after weather conditions improve|
*Sensors are located behind a fascia cover near the driver side of the lower grille.
Warning system exceptions
Due to the nature of radar technology, there may be certain circumstances in which your vehicle won’t provide a collision warning. These include:
- Stationary vehicles or vehicles moving below 6 mph (10 km/h).
- Pedestrians or objects in the roadway.
- Oncoming vehicles in the same lane.
- Severe weather conditions. (See "Blocked Sensors" section above.)
- Debris build-up on the grille near the headlamps. (See "Blocked Sensors" section above.)
- Small distance to vehicle ahead.
- Steering wheel and pedal movements are large, i.e., very active driving style.
