warning light FORD EXPLORER 2021 Repair Manual

11.
Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label, affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver seating position or
Tire Label located on the B-Pillar or
the edge of the driver door.
CHANGING A ROAD WHEEL WARNING: If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 368). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring system sensor for
damage. Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by us. If the dissimilar spare tire or wheel
is damaged, you should replace it rather
than repair it.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and wheels
and can be one of three types:
1. T-type mini-spare:
This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded in
the sidewall.
2. Full-size dissimilar spare with label
on wheel:
This spare tire has a label on
the wheel that states: THIS WHEEL AND
TIRE ASSEMBLY FOR TEMPORARY USE
ONLY.
When driving with one of the dissimilar
spare tires listed above, do not:
• Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
