2-4. Using other driving systems n When the system malfunctions l 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. l 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 below 6 mph (10 km/h), the warning will be displayed again. l If the malfunction screen is displayed, the detection range of the dual sensors is shortened. In this case, the necessity for obstacle evasion (whether the obstacle will come within 0.8 ft. (25 cm) of the vehicle or not) will not be calculated. n When using intuitive parking assist l The sensors' detection areas and reaction times are limited. When moving for- 2 When driving 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 areas around the vehicle's front and rear bumpers. • Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impossible. • There will be a short delay between obstacle 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 etc.). • It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system. • For long obstacles such as walls, the obstacle warning may change as the obstacle gets closer. 151
