Run-flat tires If your vehicle is equipped with run-flat tires, you can continue driving to a safe location even if they are punctured. Always use run-flat tires of the same size on all four wheels. Mixing tire sizes or construction may reduce vehicle handling stability. If necessary, contact your INFINITI dealer for assistance. Frequently check the tire pressure information display on the monitor screen and adjust pressure of each tire properly. (The order of the tire pressure figures displayed on the screen does not correspond with the actual order of the tire position.) If the vehicle is being driven with a flat tire or very low tire pressure, the low tire pressure warning system will activate and warn you of it by the low tire pressure warning light or a WARNING displayed on the monitor screen. If this occurs, pull off the road to a safe location and stop the vehicle as soon as possible. Check the tire pressure for all four wheels and adjust the pressure. if a tire is flat, replace it with a spare tire as soon as possible. WARNING Although you can continue driving with a punctured run-flat tire, remember that vehicle handling stability is reduced, which could lead to an accident and personal injury. Also, driving a long distance at high speeds may damage the tire. To drive safely: • Do not drive at speeds above 55 MPH (88 km/h) and do not drive more than 50 miles (80 km) with a punctured runflat tire. A punctured tire may burst and cause a serious accident, resulting in personal injury. • Drive safely at reduced speeds. Avoid hard cornering or braking, which may cause you to lose control of the vehicle. • If a rear tire is punctured, replace it with a non-punctured tire, especially when driving on rainy, snowy or icy roads. Always have punctured run-flat tires replaced. CAUTION Never install tire chains on a punctured run-flat tire, as this could damage your vehicle. Avoid driving over any projection or pothole, as the clearance between the vehicle and the ground is smaller than normal. Do not enter an automated car wash with a punctured run-flat tire. Have the punctured tire replaced by your INFINITI dealer as soon as possible, as the tire's performance capability is reduced. 8-40 Maintenance and do-it-yourself
