Abstract

A system for power reduction during vehicle access. A memory storing instructions executable by a processor includes instructions to receive an access message by a target vehicle, authenticate the access message, and determine either an occurrence of a power-saving condition or a non-occurrence of the power-saving condition. The instructions include activating a greeting indicator upon authentication of the access message and determining the non-occurrence of the power-saving condition, and determining not to activate the greeting indicator upon authentication of the access message and determining the occurrence of the power-saving condition.
