Tire Pressure Monitoring System (Tpms) - Required Federal Explanation - Honda Civic 2020 Owner's Manual

HANDLING THE UNEXPECTED
The TPMS may not function properly if tire type and size are mixed. Make sure
to use the same size and type of tire.
The low tire pressure/TPMS indicator may come on with a delay or may not
come on at all when:
• You rapidly accelerate, decelerate, or turn the steering wheel.
• You drive on snowy or slippery roads.
*1
• Tire chains are used.
The low tire pressure/TPMS indicator may come on under the following
conditions:
*1
• A compact spare tire is used.
• There is a heavier and uneven load on the tires, such as when towing a
trailer, than the condition at calibration.
*1
• Tire chains are used.
Driving on an extremely underinflated tire can cause it to overheat.
An overheated tire can fail.
Always inflate your tires to the prescribed level.
What to Do
n
Stop your vehicle in safe place. Check the tire pressures and adjust the
pressures to the specified level. The specified tire pressure is on a label on
the driver's doorjamb.

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

n
U.S. models
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.
When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to function properly.
