Tire Pressure Monitor System

The Tire Pressure Monitor System (TPMS) uses radio

and sensor technology to check tire pressure levels.

The TPMS sensors monitor the air pressure in your

vehicle’s tires and transmit tire pressure readings to a

receiver located in the vehicle.

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.

See Tire Pressure Monitor Operation on page 5-67 for

additional information.
