Specific Gravity Check

WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a close check on charge condition to prevent over-discharge.
  1. Read hydrometer and thermometer indications at eye level.
  2. Use the chart below to correct your hydrometer reading according to electrolyte temperature.
