If your vehicle is equipped with a stop/start system, it will be fitted with two batteries.

See the following steps for jump starting:

  1. Apply the parking brake, shift the automatic transmission to PARK (P) (manual transmission in NEUTRAL), and turn the ignition off.
  2. Turn off the heater, radio, and all electrical accessories.
  3. Pull up and remove the protective cover over the positive (+) remote jump-start terminal.
  4. If another vehicle is used to jump-start the battery, park the vehicle within reach of the jumper cables, apply the parking brake, and make sure the ignition is off.
  • Keep clear of the radiator cooling fan whenever the hood is open. The fan may start at any time when the ignition key is in the ON position. You may be injured by the moving fan blades.
  • Remove any metal jewelry, such as rings, watch straps, and bracelets, that could make unintentional electrical contact. You may be seriously injured.
  • Batteries contain sulfuric acid, which can burn skin or eyes, and generate hydrogen gas, which is flammable and explosive. Keep open flames and sparks away from the battery.
