The starter battery in the car can be replaced without the help of a workshop.
Removal
First of all: Take the remote control key from the ignition switch and wait at least 5 minutes before any electrical connections are touched - this is because the car's electrical system needs to store the necessary information to control modules.
Open the clips on the front cover and remove the cover.
Release the rubber moulding so that the rear cover is free.
Remove the rear cover by screwing one quarter turn and lifting it away.
Warning
Connect and remove the positive and negative cables in the correct order.
