Your Ve .cle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps
the
environment. All recommended maintenance procedures
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.
