Collision warning system limitations
Due to the nature of radar technology, there may be certain instances
where vehicles will not provide a collision warning. These include:
•
Stationary or slow moving vehicles below 6 mph (10 km/h).
•
Pedestrians or objects in the roadway.
•
Oncoming vehicles in the same lane.
•
Severe weather conditions (see also blocked sensor section).
•
Debris build-up on the grille near the headlamps (see block 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 will alert the driver).
In addition, sun load and sunglasses may reduce the visibility of the
warning lamps. 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. Check with
your authorized dealer to have your collision warning radar checked for
proper coverage and operation.
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.
Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor, located behind a
fascia cover near the driver side of
the lower grille, have been
obstructed. When the radar signals
are obstructed, a vehicle ahead
cannot be detected and the collision
warning system will not function.
The following table lists possible causes and actions for this message
being displayed.
