Q: WHY IS PROPER TIRE INFLATION IMPORTANT:
Keeping your tires at the recommended pressure is essential for the
safe and efficient operation of your vehicle. Safety experts estimate
that 25 percent of automobiles are running on tires with lower than
recommended pressure. Properly inflated tires run cooler, last longer,
and improve fuel economy.
Q: WHY DOES TIRE PRESSURE CHANGE:
Many factors affect tire pressure, and that is why it is so important
to check your tires at least once a month and before going on long
trips. Tire pressure can decrease due to tire damage, slow leaks, or
changes in outside temperature. For example, when the weather changes,
your tire pressure changes too. For every drop of 10 degrees Fahrenheit
in temperature, your tires lose 1 psi. Tires also deflate naturally over
time, as much as 1.5 psi per month.
Q: HOW DOES THE NEW TIRE PRESSURE MONITORING SYSTEM WORK?:
Sophisticated sensors in the automobile continuously monitor tire
pressure, and the warning light goes on when a tire is 25 percent or
more below the appropriate tire pressure.
Q: WHEN WILL THE NEW TIRE PRESSURE MONITORING SYSTEM BE AVAILALBLE?:
The U.S. government, through the National Highway Traffic Safety
Administration (NHTSA), requires Tire Pressure Monitoring Systems on all
passenger cars and light trucks by the 2008 vehicle model year. Check
your owners manual to see if your vehicle is equipped with a Tire
Pressure Monitoring System. Many models have already been equipped with a
Q: IF THE WARNING LIGHT GOES ON AND OFF, WHAT DOES THAT MEAN?:
On cold mornings, the warning light may illuminate and then
extinguish as tire pressure increases due to driving or outside air
temperature increases. Additionally, if the warning light goes on and
off, a malfunction in the system is indicated by a blinking light (for a
period of 60 seconds to 90 seconds). After blinking for the brief time,
the warning light can remain on. You should then contact your dealer
for a system inspection.
Q: HOW SOON DO I NEED TO FILL MY TIRES IF THE LIGHT GOES ON?:
A: Please heed the warning light and check your tires as soon as possible.
Q: DOES THE WARNING LIGHT ALWAYS MEAN THAT THE TIRE PRESSURE IS LOW?:
The warning light may indicate a system malfunction requiring a
dealers attention. If the warning light flashes before it is
continuously on, but the tire pressure is found to be within the
appropriate range, contact your dealer for a system inspection.
Q: WHAT ELSE DO I NEED TO DO FOR TIRE SAFETY?:
The Tire Pressure Monitoring System is a tool to keep you informed
about low tire pressure, but it is no substitute for regular tire
maintenance. Check your tire pressure at least once a month and before
going on long trips. Consult your owners manual on replacing a tire or
using a spare tire.
