Measuring and adjusting air pressure to achieve proper inflation
Check and, if necessary, adjust the pressure of each tire (including the spare)
at least once a month and before any long journey. Check the tire pressures when
the tires are cold. Use a pressure gauge to adjust the tire pressures to the specific
values. Driving even a short distance warms up
