NOTE: Vehicles with keyless lock system only have Remote Keyless Entry (RKE) and vehicles without keyless lock system only have Remote Receiver Module (RRX). For the market in Japan there is only Remote Keyless Entry (RKE) regardless of lock system.

The tire pressure warning function is checked by the central electronic module (CEM). The system must give a warning to driver in the driver information module (DIM) display if the air pressure in one of the tires is lower than the predetermined parameter.
