Black plate (51,1)Cadillac CTS Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-6081492) - 2014 - CRC 1st Edition - 7/2/13Vehicle Care 10-51Warning (Continued)driven at high speeds, make surethe tires are rated for high-speedoperation, in excellent condition,and set to the correct cold tireinflation pressure for thevehicle load.Vehicles with P245/45R17 95V,P245/40R18 93V, or 255/35R19 96V size tires requireinflation pressure adjustment whendriving the vehicle at speeds of160 km/h (100 mph) or higher. Setthe cold inflation pressure to280 kPa (41 psi).Vehicles with 245/40R18 93Y and275/35R18 95Y size tires requireinflation pressure adjustment whendriving the vehicle at speeds of160 km/h (100 mph) or higher. Setthe cold inflation pressure to300 kPa (44 psi).Return the tires to therecommended cold tire inflationpressure when high-speed drivinghas ended. See Vehicle Load Limitson page 9-11 and Tire Pressure onpage 10-49.Tire Pressure MonitorSystemThe Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tirepressure telltale when one or moreof your tires is significantlyunder-inflated.Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under-inflated tirecauses the tire to overheat and canlead to tire failure. Under-inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.Please note that the TPMS is not asubstitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under-inflation has
