STARTING AND DRIVING D The degree of the tread wear is very different among the installed tires. D Rapid acceleration/deceleration or sharp turns are continued. D Towing a trailer. D The loading is over the limit or unbalanced. D Initialization was not performed correctly after replacing or rotating tires or wheels. D The outside temperature is below 0_C (32_F) or above 40_C (104_F). If the warning message appears again on the multi−information display after adjusting tire inflation pressure, the system may be malfunctioning. Have your vehicle checked by your Lexus dealer as soon as possible. CAUTION When the tire pressure warning message appears, observe the following instructions: D Adjust the tire inflation pressure to the specified level as soon as possible. D Avoid abrupt steering wheel maneuvering and braking. If the vehicle tires are deteriorated, you could lose control of the steering wheel or the brakes, causing death or serious injury. Note: The tire pressure monitoring system on your vehicle will warn you when one of your tires is significantly under−inflated and when some combinations of your tires are significantly under−inflated. However, there are other combinations of significantly under−inflated tires for which your tire pressure warning system may not warn you. These other combinations are relatively common, accounting for approximately half the instances in which vehicles have significantly under−inflated tires. For example, your system may not warn you when both tires on the same side or on the same axle of your vehicle are significantly under−inflated. It is particularly important, therefore, for you to check the tire inflation pressure in all of your tires regularly and maintain proper pressure. 372
