The driver's and front passenger's seats are equipped with a headrest for the occupant's safety and comfort.
The headrest not only provides comfort for the driver and front passenger, but also helps protect the head and neck in the event of a rear collision.
For maximum effectiveness in case of an accident, the headrest should be adjusted so the middle of the headrest is at the same height of the center of gravity of an occupant's head.
Generally, the center of gravity of most people's head is similar with the height of the top of their eyes. Also, adjust the headrest as close to your head as possible. For this reason, the use of a cushion that holds the body away from the seatback is not recommended.
WARNING - Headrest removal/adjustment
CAUTION
Excessive pulling or pushing may damage the headrest.

To raise the headrest, pull it up to the desired position (1). To lower the headrest, push and hold the release button (2) on the headrest support and lower the headrest to the desired position (3).

The headrest may be adjusted forward to 4 different positions by pulling the headrest forward to the desired detent.
To adjust the headrest to it’s furthest backwards position, pull the headrest fully forward to the farthest position and release it.
Adjust the headrest so that it properly supports the head and neck.

✽ NOTICE

1. Recline the seatback (2) with the recline switch (1).
2. Raise headrest as far as it can go.
3. Press the headrest release button (3) while pulling the headrest up (4).
WARNING - Headrest Removal
NEVER allow anyone to ride in a seat with the headrest removed. Headrests can provide critical neck and head support in a crash.

2. Recline the seatback (4) with the recline switch (3).
3. Adjust the headrest to the appropriate height.
WARNING - Headrest Reinstallation
