Tire Pressure Monitoring System - Ford FOCUS Owner's Manual

TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system
is not a substitute for manually
checking tire pressures. You should
periodically check tire pressures using a
pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury.
You must check the tire pressures
(including the spare tire where applicable)
every two weeks when the tires are cold.
You must inflate the tires to the correct
pressure.
See Wheels and Tires (page 207). The tire
pressures are also on the tire inflation
pressure label (located on the edge of
driver door or the B-Pillar).
As a driver assistance feature, your vehicle
has a tire pressure monitoring system. A
warning lamp will illuminate when one or
more of the tires are significantly
under-inflated. If the low tire pressure
warning lamp illuminates, you should stop
your vehicle as soon as it is safe to do so,
check the tires and inflate them to the
correct pressure.
Driving on under-inflated tires can:
• Cause them to overheat.
• Lead to tire failure.
• Reduce fuel efficiency.
• Reduce tire life.
• Affect vehicle handling or stopping
ability.
The system is not a substitute for correct
tire maintenance.

Wheels and Tires
You must maintain the correct tire
pressures, even if low tire pressure has not
illuminated the warning lamp.
The tire pressure monitoring system has a
system malfunction indicator to warn you
when the system is not operating correctly.
The malfunction indicator and low tire
pressure warning lamp have a combined
function. When the system detects a
malfunction, the warning lamp will flash
for approximately one minute and then
remain illuminated. This sequence will
occur every time you switch the ignition on
while the malfunction remains. The system
has detected a fault that requires service.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressures. A
malfunction may occur for a variety of
reasons, including the installation of a
replacement tire or wheel that prevents
the system from functioning correctly.
Always check the tire pressure monitoring
system malfunction warning after
replacing one or more tires or wheels on
your vehicle. Make sure the replacement
tires or wheels allow the system to
continue to function correctly. See When
the Temporary Spare Tire is Installed
in this section.
How Temperature Affects the Tire
Pressures
Under normal driving conditions tire
pressures may increase by up to 0.3 bar
from a cold start situation.
If the vehicle is stationary overnight and
the temperature significantly lower than
the daytime temperature, tire pressures
may decrease by up to 0.2 bar when there
is a drop in the ambient temperature of
31°F (17°C) or more. The system detects
this pressure decrease as being
significantly below the correct inflation
pressure and the warning lamp illuminates.
