hicle control could lead to an accident.
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 the tires and increases the tire pres-
sures. Also, the tire pressures are affected by the
ambient temperature. It is best to check tire pres-
sure outdoors before driving the vehicle. When a
tire becomes warm, the air inside it expands,
causing the tire pressure to increase. Be careful
not to mistakenly release air from a warm tire to
reduce its pressure.

Glossary of tire terminology

Cold tire pressure

than 1 mile or has been standing for three hours
or more.
Maximum inflation pressure
Consumer information and Reporting safety defects

Recommended inflation pressure
The cold inflation pressure recommended by a
vehicle manufacturer.

1)The sidewall that contains a whitewall, bears
white lettering or bears manufacturer, brand,
