2-4. Using other driving systems
■When the system malfunctions
●If a malfunction occurs and no obstacles have been detected, a warning is dis-
played, and a malfunction beep sounds for 7 seconds. 
If an obstacle has been detected, or another malfunction occurs in a different
sensor
, the malfunction beeps will not sound.
●In the following circumstances the displayed warning will disappear:
• If you switch the screen to a different mode.
• If you turn OFF the intuitive parking assist main switch.
• If the vehicle speed exceeds 6 mph (10 km/h). Once the vehicle speed drops
b
elow 6 mph (10 km/h), the warning will be displayed again.
●If the malfunction screen is displayed, the detection range of the dual sensors is
shortened. In this case, the necessity fo r obstacle evasion (whether the obstacle
will come within 0.8 ft. (25 cm) of the vehicle or not) will not be calculated.
■When using intuitive parking assist
●The sensors' detection areas and reaction times are limited. When moving for -
ward or reversing, check the areas surrounding the vehicle (especially the sides
of the
vehicle) for safety, and drive slowly, using the brake to control the vehicle’s
speed.
• The sensors' detection areas are limited to the ar
eas around the vehicle’s front
and rear bumpers.
• Depending on the shape of the obstacle
and other factors, the detection dis-
tance may shorten, or dete ction may be impos
sible.
• There will be a short delay between ob stacl
e detection and display. Even at
slow speeds, there is a possibility that the obstacle will come within 0.8 ft. (25
cm) of the vehicle before the display is shown and the warning beep sounds.
• Braking distance may differ according to the road conditions (rain, gravel
et
c.).
• It might be difficult to hear beeps due to the volume of audio system or air fl
ow noise of air conditioning system.
• For long obstacles such as walls, the obstacle warning may change as the o
bstacle gets closer.
