When Inflating your Tires
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure
How Temperature Affects your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase approximately 2 to 4 psi (14
to 28 kPa) from a cold start situation. If the
MKZ (CC9)
Wheels and Tires
vehicle is stationary overnight with the
outside temperature significantly lower
than the daytime temperature, the tire
pressure may decrease approximately 3
psi (21 kPa) for a drop of 30°F (17°C) in
ambient temperature. This lower pressure
value may be detected by the TPMS as
being significantly lower than the
recommended inflation pressure and
activate the TPMS warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check
air pressure in the road tires. If any tire is
under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.
