The vehicle is driven on rough
roads such as in areas where there
is grass and foliage or off-road.

on page 4-143.
Always use tires for all wheels that
are of the specified size, and the
same manufacture, brand, and tread

Rearward detection function
The rearward detection function is
designed to reduce damage in the
event of a collision with a target object
when reversing.
The rearward detection function
detects obstructions using the rear
ultrasonic sensors. In addition, if there
is the possibility of your vehicle
colliding with a target object at the rear
while you are driving in reverse, you
are notified of possible danger by a
warning sound and a warning
indication on the display.
Furthermore, if the possibility of a
collision increases, brake control is
performed to reduce damage in the
event of a collision.
WARNING
Always check the surrounding area
visually when reversing the vehicle:
The operation of the rearward
detection function has certain
limitations. Therefore, the function
might not operate or it might be
delayed even if there is a target object
at the rear of your vehicle. Always
make it your responsibility as a driver
to check the rear.
