vehicle
in good working condition, but also helps the
environment.

are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle. To help protect our
environment. and to keep your vehicle
in good
condition, please maintain your vehicle properly.
