tire valve stem caps
This is to remind you of the importance of the tire valve stem cap. These caps need to be installed on every tire, regardless if the vehicle is equipped with
TPMS or not. Without these caps, dirt and moisture can interfere with the proper sealing of the tire valve stem. This can result in a gradual loss of tire
pressure or interfere with adding air to the tire. In turn this may result in a TPMS lamp coming on and an inconvenienced customer. The cap is gray in
color, part # S0A342LT09. The accessory SPT valve stem cap may also be used and will not affect the TPMS operation.
