To remove the Car Batteries cover, take off the fasteners that secure it in place and set the cover aside. Next, unplug the cable from the negative battery terminal followed by the cable from the positive terminal. Remove the battery hold-down clamp and carefully lift it out. If you are changing the battery, make sure that the new one is equal to the last one with the dimensions, amperage rating, and cold cranking rating. Installation for the battery is the reverse of removal. Be sure to connect the positive cable first and the negative cable last.

Carefully lift out the heavy battery.

You should inspect and clean them if necessary.

You should use specially-treated felt washers and coat the terminals and cable clamps with petroleum jelly or grease to prevent further corrosion. Tighten the nuts on the cable clamps and hold-down clamp, being cautious not to overtighten and crack the battery case. Check the battery tray and hold-down clamp bolts for tightness.

Memory-savers are used to maintain power to certain circuits while disconnecting the battery.

It is important to disconnect the cable from the negative battery terminal first and hook it up last to avoid shorting the battery.

The display will show "System Initializing." Ensure that the hybrid system is started, set the parking brake, apply the footbrake, put the vehicle in the P position on level ground, and turn the steering wheel all the way to the right and then all the way to the left while parked.
