D Initialization was not performed correctly after replacing or rotating tires or wheels. CAUTION When the tire pressure warning light comes on, observe the following instructions: D Vehicles with the standard tires- Adjust the tire pressure to the specified level as soon as possible. D Vehicles with the run- flat tires- Decelerate as soon as possible to the lowest appropriate speed that conditions permit. Do not drive for longer than 160 km (100 miles) or over 90 km/h (55 mph). Note: The tire pressure warning 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 warm 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 warm 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 pressure in all of your tires regularly and maintain proper pressure.
