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 about 2
–4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as being significantly lower than the
recommended inflation pressure and
activate the system 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
the 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.
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING
When a wheel is installed, always remove any corrosion, dirt or foreign materials
present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure that any fasteners
that attach the rotor to the hub are secured so they do not interfere with the mounting
surfaces of the wheel. Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen and the wheel to come off
while your vehicle is in motion, resulting in loss of control. Ib-ft (Nm)

* Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford
recommended replacement fasteners.
Retighten the lug nuts to the specified torque within 100 miles (160 kilometers) after any
wheel disturbance (such as tire rotation, changing a flat tire, wheel removal).
