9. sensors are accurately calibrated with nitrogen and are accurate to 4psi Many tyre pressure gauges are not very accurate and readings may vary with moisture in the air Note that the pressure and temperature data displayed are not instantaneous but are values stored in the monitor and updated every few minutes If in any doubt have your tyres checked by a specialist Monitor reads 0 0 with flashing battery icon This indicates that a booster is in use and has low battery 13 MANAGING TYRE PRESSURES Effects of incorrect pressure Incorrectly inflated tyres reduce the contact area with the road leading to less grip increased braking distances poor cornering uneven tyre wear If tyres are under inflated they have greater rolling resistance so they waste fuel and wear faster Driving on tyres below a critical inflation pressure can cause a blow out and can damage wheel rims because the tyres no longer support the vehicle What is the correct pressure The recommended cold inflation pressures are given in the vehicle handbook and often also on a label in the door frame There may be different pressures for front and rear tyres and higher pressures may be recommended when the vehicle is fully loaded These recommended pressures are designed to give the best balance between comfort road holding and fuel economy for a given vehicle The side wall of the tyre is embossed with the maximum pressure rating for the tyre Th
