A vehicle suddenly comes close such
as by cutting into the lane.



To prevent incorrect operation of the
system, use tires of the same specified
size, manufacturer, brand, and tread
pattern on all four wheels. In addition,
do not use tires with significantly
different wear patterns or tire pressures
on the same vehicle (Including the
temporary spare tire).

If the battery power is weak, the system
may not operate correctly.

When driving on roads with little traffic
and few vehicles ahead or obstructions
for the front radar sensor to detect,
“Safety and Driver Support Systems
Temporarily Disabled. Front Radar
Obscured. Drive Safely” may be
temporarily displayed, however, this
does not indicate a problem.



The radar sensors are regulated by the
relevant radio wave laws of the country
in which the vehicle is driven. If the
vehicle is driven abroad, authorization
from the country in which the vehicle is
