When the System Does Not Seem to Work Properly
If the URPA system will not activate due to a temporary condition, the message PARK ASSIST OFF will be displayed on the DIC and a red light will be shown on the rear URPA display when the shift lever is moved into R (Reverse). This occurs under the following conditions:
• The driver disables the system.
• The ultrasonic sensors are not clean. Keep the vehicle’s rear bumper free of mud, dirt, snow, ice and slush. For cleaning instructions, see Washing Your Vehicle.
• A trailer was attached to the vehicle, or a bicycle or an object was hanging out of the trunk during the last drive cycle, the red light may illuminate in the rear display. Once the attached object is removed, URPA will return to normal operation.
• A tow bar is attached to the vehicle.
• The vehicle’s bumper is damaged. Take the vehicle to your dealer/retailer to repair the system.
• Other conditions may affect system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck.
If the system is still disabled after driving forward at least 25 km/h (15 mph), take the vehicle to your dealer/retailer.
