'05 4Runner_U (L/O 0504) If the low tire pressure warning light comes on or blinks, do the following. If the warning light comes on: Stop your vehicle in a safe place as soon as possible and check that the inflation pressure of all tires (including the spare tire) is as specified on the tire and loading information label. (See "Checking tire inflation pressure" on page 381 in Section 7- 2.) If the warning light comes on even after tire inflation pressure adjustment, you may have a flat tire. If you have a flat tire, replace it with the spare tire. For details, see "If you have a flat tire" on page 335 in Section 4. The warning light goes off a few minutes after air is put into the deflated tire. This warning light may turn on due to natural causes such as natural air leaks or tire pressure changes caused by temperature. In this case, adjusting the tire pressure will turn off the warning light. CAUTION When the tire pressure warning light comes on, observe the following instructions: NOTICE z Do not use liquid sealants for a flat tire as air pressure sensors will be damaged. z When the tires must be repaired or replaced, have them repaired or replaced by the nearest Toyota dealer or authorized tire dealer. The tire pressure sensors will be affected by the installation or removal of tires. z The tire pressure warning system is not to be used as a substitute for regular inspections. Be sure to check the air pressure in the tires on a regular basis. z When the tires must be replaced, replace the grommets for air pressure sensors as well. D Depending on the conditions, reduce to an appropriate speed as soon as possible. D Adjust the tire pressure to the specified level as soon as possible. D Avoid abrupt steering wheel maneuvering and braking. Tire deterioration may reduce steering wheel control and brake effectiveness. This may lead to serious injury or death. D The tire pressure warning system may not activate immediately if sudden bursts of air leakage occur. 189
