icle features Tire Pressure Monitoring System (TPMS) - 2500 only TPMS Messages • A Tire Pressure Monitoring Light and a "low tire" message will display along with an audible chime if one or more of your vehicle's four road tires are significantly under-inflated when operating in either TPMS mode. • It is recommended that you check the tire pressure in the morning when the tires are cool; inflate each tire to the recommended pressure for your vehicle. The light will turn off after your vehicle's tire pressures are properly inflated and the pressure has been recognized. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) before light will turn off. • Temperature changes can affect tire pressures, causing the TPMS light to turn on. Tire pressures will also increase as the vehicle is driven - this is normal and you should not adjust for this increased pressure. • Driving on under-inflated tires reduces your vehicle's fuel efficiency and tire tread life. If your spare tire is in use on the vehicle, the TPMS light may turn on. Refer to your Owner's Manual.
