necessary to keep this vehicle in good working

Your Vehicle and the Environment

Proper vehicle maintenance not only helps to keep the
vehicle in good working condition, but also helps the
environment. All recommended maintenance is
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 the vehicle. To help protect the environment, and to
keep the vehicle in good condition, be sure to maintain
the vehicle properly.
