WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoring
system measures the vehicle's
tire pressures. A warning lamp
illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW WARNING: If the tire pressure
monitor sensor becomes damaged it
may not function. WARNING:
Under-inflation is the
most common cause of tire failures and
may result in severe tire cracking, tread
separation or blowout, with unexpected
loss of vehicle control and increased risk
of injury. Under-inflation increases
sidewall flexing and rolling resistance,
resulting in heat buildup and internal
damage to the tire. It also may result in
unnecessary tire stress, irregular wear,
loss of vehicle control and accidents. A
tire can lose up to half of its air pressure
and not appear to be flat! WARNING:
To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification
Label (on the door hinge pillar,
door-latch post or the door edge that
meets the door-latch post, next to the
driver seat) or the Tire Label on the
B-Pillar or the edge of the driver door. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure
recommended by the vehicle manufacturer
on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle
’s handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.

allows your vehicle to connect to a mobile
network and for you to access a range of
features. When used in conjunction with
the FordPass app, it could allow you to
monitor and control your vehicle further,
for example checking the tire pressures,
the fuel level and the vehicle location. For
additional information, refer to the local
Ford website.
CONNECTED VEHICLE

It is important to rely upon your dealership
to properly diagnose and repair your
vehicle.
We strongly recommend only using our
genuine or our authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. Have discolored fluids that also
show signs of overheating or foreign
material contamination checked
immediately. Make sure to change the vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections. Check Every Month
The air filter restriction gauge. 1
The engine oil level.
Function of all interior and the exterior lights.
The tires including the spare for wear and proper pressure. The windshield washer fluid level.
The fuel and water separator. Drain if necessary or if indicated by the information display. 1
The holes and slots in the tail pipe to make sure they are functional and clear of debris. 1
1 Diesel vehicles only.
