2.Measure the height from the center ofyour headlamp, indicated by a 3millimeter circle on the lens, to theground and mark an 8 ft (2.4 m)horizontal reference line on the verticalwall or screen at this height, a piece ofmasking tape works well.
3.Switch on the low beam headlamps toilluminate the wall or screen and openthe hood. Cover one of the headlampsso no light hits the wall.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoringsystem measures the vehicle's tirepressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
WARNING: Under-inflation is themost common cause of tire failures andmay result in severe tire cracking, treadseparation or blowout, with unexpectedloss of vehicle control and increased riskof injury. Under-inflation increases sidewallflexing and rolling resistance, resulting in
heat buildup and internal damage to thetire. It also may result in unnecessary tirestress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance Certification Label(on the door hinge pillar, door-latch postor the door edge that meets the door-latchpost, next to the driver seat) or the TireLabel on the B-Pillar or the edge of thedriver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires of adifferent size than the size indicated on thevehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
