06 04.25 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. Failure to do so may cause the tire pressure sensors to be damaged when the tires are removed or installed. 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 air pressure sensors are removed, check the grommets for damage, and make sure that the grommets are free from dirt, dust and any other foreign matter. If air leakage is found, replace the grommets. z Tire inflation pressure should be adjusted for all tires (including the spare tire). z Warning tends to turn on when driving at lower outside temperature, such as in winter, because tire inflation pressure will be decreased due to the low temperature. In this case, after adjustment and initialization, leave the ignition on for about 20 minutes and increase the tire inflation pressure by 20 to 30 kPa. If the warning light blinks: The tire pressure warning system may be malfunctioning. Contact your Toyota dealer. SYSTEM MALFUNCTION The tire pressure warning system does not function properly under certain circumstances. In the following cases, the low tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal. D A lot of snow or ice covers the vehicle, in particular, around the wheels or wheel housings. D The tires are not equipped with an air pressure sensor. D D D D Snow tires or tire chains are used. Non- genuine Toyota wheels are used. The sensor battery is expired. The system cannot receive radio waves from the air pressure sensor on the spare tire, depending on where the sensor is located when the spare tire is mounted on the vehicle. In this case, rotate the spare tire by about 90° so that the system can receive radio waves. D Electric devices facilities using similar radio wave frequencies are nearby. D A radio set to similar frequencies is in use. 194 2006 TACOMA from Jan.'06 Prod. (OM35871U)
