03_SEQUOIA_U (L/O 0301) Checking and replacing tires If a tire frequently needs refilling, have it checked by your Toyota dealer. The following instructions for checking tire pressure should be observed: Tread wear indicator CAUTION Keep your tire pressure properly inflated. Otherwise, the following conditions may occur and cause an accident resulting in death or serious injuries. Low tire pressure (underinflation)- D The pressure should be checked only when the tires are cold. If your vehicle has been packed for at least 3 hours and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure reading. D Always use a tire pressure gauge. The appearance of a tire can be misleading. Besides, tire pressures that are even just a few pounds off can degrade ride and handling. D Excessive wear D Uneven wear D Poor handling D Possibility of blowouts from overheated tire CHECKING YOUR TIRES Check the tire tread for the tread wear indicators. If the indicators show, replace the tires. The tires on your Toyota have built −in tread wear indicators to help you know when the tires need replacement. When the tread depth wears to 1.6 mm (0.06 in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tire should be replaced. The lower the tread, the higher the risk of skidding. The effectiveness of snow tires is lost if the tread wears down below 4 mm (0.16 in.). D Do not bleed or reduce tire pressure after driving. It is normal for the tire pressure to be higher after driving. D Poor sealing of the tire bead D Wheel deformation and/or tire separation High tire pressure (overinflation)- D Never exceed the vehicle capacity weight. The passenger and luggage weight should be located so that the vehicle is balanced. D Poor handling D Excessive wear at the center of the tire tread D Be sure to reinstall the tire inflation valve caps. Without the valve caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible. D A greater possibility of tire damage from road hazards 364 2003 SEQUOIA from Jan. '03 Prod. (OM34422U)
