1. TIRE PRESSURE WARNING SYSTEM PRECAUTION




a. When the tire pressure warning lamp comes on, immediately check the air pressure of all tires and adjust to the specified pressure.
b. This system requires initializing after changing tires or wheels, or after rotating the tires.

Set tire pressure within the specified range before initializing. If the tire air pressure is not within the specified range, the tire pressure warning system will not function.

c. In the following cases, the system may not operate normally.
- A compact spare tire, snow tire, or tire chains are used.
- The tire inflation pressure is excessively higher than specified or tire inflation pressure suddenly drops due to bursting or other causes.
- The vehicle is driven on a slippery road surface such as rough or frozen roads.
- The vehicle speed is less than 19 mph (30 km/h) or more than 62 mph (100 km/h), and the driving duration is less than 5 minutes.
- The tires differ in tread pattern or manufacture.
- The tires are not the specified size.
- The tread wear is very different among the installed tires.
- The pressure of two or more tires drops at the same time.
- Rapid acceleration/deceleration or sharp turns is continued.
- The loading is over the limit or imbalanced.
- Initialization was not performed correctly after replacing or rotating tires or wheels.
- The outside temperature is below 32 °F (0 °C) or above 104 °F (40 °C).

2. FAIL-SAFE FUNCTION

a. When a system malfunction occurs in the tire pressure warning system, the tire pressure warning lamp blinks.
b. The result of this diagnosis is stored in the skid control ECU.
