When the System Does Not Seem to Work Properly • The driver disables the system. • The parking brake pedal is depressed. • The ultrasonic sensors are not kept clean. So be sure to keep your vehicle's front and rear bumpers free of mud, dirt, snow, ice and slush. For cleaning instructions, see Washing Your Vehicle on page 5-90. Side Blind Zone Alert Your vehicle may have a Side Blind Zone Alert (SBZA) system. Read this entire section before using the system. {CAUTION: The Side Blind Zone Alert (SBZA) system does not detect vehicles outside the side blind zones, which may be rapidly approaching. SBZA is not designed to detect pedestrians, bicyclists, or animals. SBZA is only a lane change aid. If you do not use proper care before changing lanes, vehicle damage, injury, or death could occur. Even with SBZA, always check your vehicle's mirrors, glance over your shoulder, and start your turn signal before changing lanes. The SBZA system is an aid that may help you avoid lane change crashes with vehicles in your side blind spots (zones). When the system detects a vehicle in the side blind zone, amber SBZA displays will light up in your side mirrors. • A trailer was attached to your vehicle, or a bicycle or an object was hanging out of your trunk during your last drive cycle, the red light may illuminate in the rear display. Once the attached object is removed, UFRPA will return to normal operation. • A tow bar is attached to your 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 15 mph (25 km/h), take your vehicle to your dealer/retailer. 2-47
