If your vehicle is equipped with a Stop/Start system, it will be equipped with two batteries.

See below steps to prepare for jump starting:

  1. Apply the parking brake, shift the automatic transmission into PARK (P) (manual transmission in NEUTRAL) and turn the ignition OFF.
  2. Turn off the heater, radio, and all electrical accessories.
  3. Pull upward and remove the protective cover over the remote positive (+) battery post.
  4. If using another vehicle to jump start the battery, park the vehicle within the jumper cable’s reach, apply the parking brake and make sure the ignition is OFF.

WARNING!

  • Take care to avoid the radiator cooling fan whenever the hood is raised. It can start anytime the ignition switch is ON. You can be injured by moving fan blades.
  • Remove any metal jewelry such as rings, watch bands and bracelets that could make an inadvertent electrical contact. You could be seriously injured.
  • Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks away from the battery.

WARNING!

Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.
