TPMS reset procedure (if applicable)

This procedure is only required after tire rotation on vehicles

with different front and rear tire pressures.

WARNING: To determine if your vehicle requires two different

pressures - one for the front tires and one for the rear tires -

refer to the Safety Compliance Certification Label or Tire Label which

is located on the B-Pillar or the edge of the driver’s door. See Vehicle

Loading in this chapter for more information.

Overview

To provide the vehicle’s load carrying capability, some trucks require

different recommended tire pressures in the front tires as compared to

the rear tires. The Tire Pressure Monitoring System (TPMS) equipped on

these vehicles is designed to illuminate the Low Tire Pressure Warning

indicator at two different pressures; one for the front tires and one for

the rear tires. Since tires need to be rotated to provide consistent

performance and maximum tire life, the Tire Pressure Monitoring System

needs to know when the tires are rotated to determine which set of tires

are on the front and which are on the rear. With this information, the

system can detect and properly warn of low tire pressures.

WARNING: Always perform the TPMS reset procedure after tire

rotation. If the system is not reset, it may not provide a low tire

pressure warning when necessary.
