2-34 Features and Controls Outside Convex Mirror { CAUTION A convex mirror can make things (like other vehicles) look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on the right. Check the inside mirror or glance over your shoulder before changing lanes. The passenger side mirror is convex shaped. A convex mirror's surface is curved so more can be seen from the driver seat. Object Detection Systems Ultrasonic Rear Parking Assist (URPA) For vehicles with the Ultrasonic Rear Parking Assist (URPA) system, it operates at speeds less than 5 mph (8 km/h), and assists the driver with parking and avoiding objects while in R (Reverse). The sensors on the rear bumper are used to detect the distance to an object up to 8 feet (2.5 m) behind the vehicle, and at least 10 inches (25.4 cm) off the ground. { CAUTION The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect: • objects that are below the bumper, underneath the vehicle, or if they are too close or far from the vehicle • children, pedestrians, bicyclists, or pets. If you do not use proper care before and while backing; vehicle damage, injury, or death could occur. Even with URPA, always check behind the vehicle before backing up. While backing, be sure to look for objects and check the vehicle's mirrors. Outside Heated Mirrors < (Rear Window Defogger): Press to heat the mirrors.
