approximately 30 psi (207 kPa), but the TPMS Warning

Light will still be ON. In this situation, the TPMS Warning

Light will turn OFF only after the tires have been inflated

to the vehicle’s recommended cold placard pressure value.

CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.

Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor
function checked.

CAUTION!

(Continued)

After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.

NOTE:

The TPMS is not intended to replace normal tire care and

maintenance, nor to provide warning of a tire failure or

condition.

The TPMS should not be used as a tire pressure gauge

while adjusting your tire 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.

The TPMS is not a substitute for proper tire mainte-

nance, 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

Warning Light.”
