The car's traditional 12 V battery is here called "starter battery" even if the hybrid battery is often used for starting the internal combustion engine.
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
Detach the black negative cable.
Detach the red positive cable.
Detach the ventilation hose from the battery.
Loosen the screw holding the battery clamp.
Move the battery aside.
Lift it up.
