System Limitations WARNING
The collision warning system
’s brake
support only reduces collision speed
if you first apply your brakes. You must brake
as you would in 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.
• Large steering wheel and pedal
movements (very active driving style). Damage to the front end of the vehicle may
alter the radar sensor's coverage area. This
may result in missed or false collision
warnings. Have an authorized dealer check
your radar sensor for proper coverage and
operation.
