For additional information and details about the DIC operation and displays see DIC Controls and Displays on page 196 and DIC Warnings and Messages on page 200. You may notice, during cooler weather conditions, that the low tire pressure warning light and the DIC LOW TIRE message may come on when the vehicle is first started, and then turn off as you start to drive. This may be an early indicator that the air pressure in the tire(s) is getting low and needs to be inflated to the proper pressure. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. 387
