Instrument Panel ALL WHEEL DRIVE OFF If your vehicle has the All-Wheel Drive (AWD) system, this message displays when there is a compact spare tire on the vehicle, when the Antilock Brake System (ABS) warning light comes on, or when the rear differential fluid is overheating. This message turns off when the differential fluid cools. The AWD system is disabled until the compact spare tire is replaced by a full-size tire. If the warning message is still on after putting on the full-size tire, you need to reset the warning message. To reset the warning message, turn the ignition off and then back on again after 30 seconds. If the message stays on, see your dealer/retailer right away. See All-Wheel Drive (AWD) System on page 4-7 for more information. 3-51 AUTOMATIC LIGHT CONTROL OFF This message displays when the automatic headlamps are turned off.
