PROPER PREPARATION FOR STATE EMISSION INSPECTION & MAINTENANCE TEST

DESCRIPTION

Some vehicles with properly functioning emission control systems may fail certain states' emission inspection and maintenance test(s) (tailpipe emission tests).

In order to avoid the above mentioned condition, make sure the following items are observed before conducting the test:

- Engine should be warmed up but not overheating (as indicated by gauge or warning light).

- All electrical loads and A/C should be turned off.

- For 5-speed models: Neutral range should be selected.

- For automatic transmission models: "N" or "P" range should be selected.

NOTE:
All Mazda vehicles meet the U.S. EPA and California emission standards when tested under the EPA certification test procedure.

PREPARATION PROCEDURE

Perform the following before conducting the emission inspection and maintenance test:

1. Before testing, bring the engine's operating temperature to normal by operating the engine for approximately 3 minutes at 2500-3000 rpm.

NOTE:
When the cooling fan has cycled on and off twice, the engine has reached its normal operating temperature.

2. Test the vehicle as soon as possible after the engine has warmed up. Keep the engine at operating temperature during the test.
