Rear seat centre armrest
Part of the centre rear backrest can be folded out to act as a centre armrest.
There is a strap attached to the left side of the centre rear seat. Pull this strap to fold out the rear centre armrest.

The centre armrest can provide extra arm support but also contains some additional features.
Cup holder
There is a cup holder with two slots in the armrest. To access the cup holder, push the front section of the centre armrest and let go. The cup holder will slide out fully. Gently push it back in to hide it again when not in use.
Rear seat adjustment controls
On both sides of the centre armrest, there are two buttons that control the tilt of the outer rear backrests.
Small item storage
There is a small open compartment close to the headrest for storing items.
