POWER MIRROR CONTROL SYSTEM PROBLEM SYMPTOMS TABLE

Note

If the battery voltage is low, the mirror heater function may not operate. When "High Power Consumption Partial Limit On AC/Heater Operation" is displayed on the multi-information display in the combination meter assembly, inspect the battery, referring to On-vehicle Inspection for the charging system.
