Park Assist *
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating distances to obstacles using audible signals andgraphics in the center display.
Display view showing obstacle zones and sensor sec- tors.
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The marked sector indicates where the obstacle is located. The closer the vehicle symbol is to amarked sector, the closer the detected obstacleis to your vehicle. The audible signals will also speed up the closer the obstacle is to the vehicle. The volume of theaudio system will be automatically lowered. Audible signals for obstacles in front and to the sides of the vehicle are active when the vehicle is moving but will cease after the vehicle has beenstationary for approx. 2 seconds. Audible signalsfor obstacles behind the vehicle will remain activeeven when the vehicle is stationary. If a detected obstacle is within 30 cm (1 ft) from the front or rear of the vehicle, the tone willbecome constant and the active sensor's fieldclosest to the vehicle symbol will be filled in. The volume of the Park Assist audible signals can be adjusted while the signal is being given using the
>II knob or in the center display's Top
view under
Settings.
NOTE
• Acoustic warnings are only given for objects directly in front of the vehicle'spath.
