When you end this high-speed driving, return the tiresto the cold inflation pressure shown on the Tire andLoading Information label. See Loading the Vehicleon page 4-24.Example:You will find the maximum load and inflation pressuremolded on the tire’s sidewall, in small letters, near the rimflange. It will read something like this: Maximum load690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.For this example, you would set the inflation pressurefor high-speed driving at 38 psi (265 kPa).Tire Pressure Monitor SystemThe Tire Pressure Monitor System (TPMS) uses radioand sensor technology to check tire pressure levels.The TPMS sensors monitor the air pressure in yourvehicle’s tires and transmit tire pressure readings to areceiver located in the vehicle.Each tire, including the spare (if provided), should bechecked monthly when cold and inflated to the inflationpressure recommended by the vehicle manufactureron the vehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size than thesize indicated on the vehicle placard or tire inflationpressure label, you should determine the propertire inflation pressure for those tires.)As an added safety feature, your vehicle has beenequipped with a tire pressure monitoring system (TPMS)that illuminates a low tire pressure telltale when oneor more of your tires is significantly under-inflated.Accordingly, when the low tire pressure telltaleilluminates, you should stop and check your tires assoon as possible, and inflate them to the proper pressure.Driving on a significantly under-inflated tire causes thetire to overheat and can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life, and mayaffect the vehicle’s handling and stopping ability.5-66
