VEHICLE CARE 285Tyre Pressure forHigh-Speed Operation{ WarningDriving at high speeds, 160 km/h(100 mph) or higher, putsadditional strain on tyres. Sustainedhigh-speed driving causes excessiveheat build-up and can cause suddentyre failure. This could cause acrash, and you or others could bekilled. Some high-speed rated tyresrequire inflation pressureadjustment for high-speedoperation. When speed limits androad conditions allow the vehicle tobe driven at high speeds, make surethe tyres are rated for high-speedoperation, are in excellentcondition, and are set to the correctcold tyre inflation pressure for thevehicle load.Vehicles with P245/45R17 95V, P245/40R18 93V, or 255/35R19 96V sizetyres require inflation pressureadjustment when driving the vehicleat speeds of 160 km/h (100 mph) orhigher. Set the cold tyre inflationpressure to 280 kPa (41 psi).Vehicles with 245/40R18 93Y and 275/35R18 95Y or 265/35ZR19 (94Y) and295/30ZR19 (100Y) size tyres requireinflation pressure adjustment whendriving the vehicle at speeds of160 km/h (100 mph) or higher. Set thecold tyre inflation pressure to 300 kPa(44 psi).Sustained operation at speeds over160 km/h (100 mph) requires a loadlimit of the driver and one passenger,with no additional cargo. When loadedabove this level, up to the GVW, donot operate the vehicle above160 km/h (100 mph).Return the tyres to the recommendedcold tyre inflation pressure whenhigh-speed driving has ended.See Vehicle Load Limits 0 184 and TyrePressure 0 283.Tyre Pressure MonitorSystemCautionModifications made to the TyrePressure Monitor System (TPMS) byanyone other than an authorisedservice facility may voidauthorisation to use the system.The Tyre Pressure Monitor System(TPMS) uses radio and sensortechnology to check tyre pressurelevels. The TPMS sensors monitor theair pressure in your vehicle's tyres andtransmit tyre pressure readings to areceiver located in the vehicle.Each tyre, including the spare (ifprovided), should be checked monthlywhen cold and inflated to theinflation pressure recommended bythe vehicle manufacturer on thevehicle placard or tyre inflationpressure label. (If your vehicle hastyres of a different size than the sizeindicated on the vehicle placard or
