Rear parking assist

Rear parking assist
The new smart is equipped with a rear parking assist system
as special equipment. The rear parking assist system helps
the driver when reversing in tight conditions.
With the aid of ultrasonic signals that are reflected by
obstacles, an electronic control unit computes the distance
between the vehicle and the detected obstacle. The signal
transmitters and receivers are combined in the ultrasonic
sensors and there are three sensors distributed along the
rear bumper. There is a button to switch the function on and
off positioned on the left next to the steering wheel.

If the system detects an object within the monitoring range
behind the vehicle while reversing, this is indicated by an
acoustic warning. The time interval between tones provides
an indication of the distance remaining to the detected ob-
ject. The acoustic warning varies as the vehicle approaches
from long intervals through to a continuous signal.
When reverse gear is engaged with parking assist active, an
acoustic notification tone sounds.
