Traveling through turns or bends in the roadway may
result in Distronic detecting a moving vehicle traveling
in front but not in your lane of travel, causing your
vehicle to brake late or unexpectedly. You must be
prepared to intercede with accelerator or brake
application as necessary.

The Distronic system's detection zone is relatively
narrow at the start and becomes broader as it senses
further from the vehicle. Thus, Distronic may not
recognize another vehicle coming into your path close
to the front of your vehicle. You must be prepared to
intercede with braking or steering as necessary.
A vehicle not traveling directly in front of you could
cause detection problems, the actual distance to that
vehicle really being much shorter.
