Heat Protection Mode

WARNING: This page is about a different variant/trim than selected.

During very extreme off-road operation, the AWD  system utilizes a heat protection mode to protect the ATC  solenoid (part of rear axle) from damage. If the system detects an overheat condition, it enters a locked mode. If the heat in the system continues to rise once in the locked mode, the AWD  relay module disables the ATC  solenoid. Allow the system to cool down at least 10 minutes with the ignition switch in the ON position.

For concerns with the AWD  relay module or ATC  , refer to FOUR WHEEL DRIVE (4WD) SYSTEMS .
