Collision warning should automatically reactivate a short time after the weather conditions improve. System Limitations WARNING: The collision warning system's brake support can only help reduce the speed at which a collision occurs if the driver applies the vehicle's brakes. The brake pedal must be pressed just like any typical braking situation. Due to the nature of radar technology, there may be certain instances where vehicles do not 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 sensor section). • Debris build-up on the grille near the headlamps (see blocked sensor section). • Small distance to vehicle ahead. • Steering wheel and pedal movements are large (very active driving style). • High interior temperatures, which may deactivate the illumination or the warning lamps until the interior temperature reduces (audible warning still sounds). Certain conditions may reduce the visibility of the warning lamp; therefore, it is recommended to keep the audible warning on. If the front end of the vehicle is hit or damaged, the radar sensing zone may be altered causing missed or false collision warnings. See your authorized dealer to have your collision warning radar checked for proper coverage and operation.
