Factors Affecting Compass Accuracy The compass reading can be affected when you drive near a number of things - such as large buildings, bridges, power lines, and powerful antennas. Your compass can also be affected by magnetic or metallic objects placed in or on the compass sensor (the sensor is loacated on the inside rearview mirror bracket). If the compass is giving inaccurate readings, perform the calibration procedure. Speedometer The speedometer tells you how many miles (kilometers) per hour your vehicle is moving. It indicates the speed up to 120 mph or up to 199 km/h. Zone map You can press the E/M (English/Metric) button located just below the message center display to show the speed you are going in either miles per hour or kilometers per hour. 20
