Features of your vehicle
The parking assist system assists
the driver during movement of the
vehicle by chiming if any object is
sensed within the distance of 100 cm
(39 in.) in front and 120 cm (47 in.)
behind the vehicle.This system is a supplemental sys-
tem and it is not intended to nor does
it replace the need for extreme care
and attention of the driver.
The sensing range and objects
detectable by the sensors are limit-
ed. Whenever moving pay as much
attention to what is in front and
behind of you as you would in a vehi-
cle without a parking assist system.
Operation of the parking
assist system

parking assist button is pressed with
the engine start/stop button ON.
PARKING ASSIST SYSTEM

The parking assist system
should only be considered as a
supplementary function. The
driver must check the front and
rear view. The operational func-
tion of the parking assist system
can be affected by many factors
and conditions of the surround-
ings, so the responsibility rests
always with the driver.
