If your vehicle is equipped with the headrest swing
feature, the front headrests may be adjusted
forward to four positions by pulling it forward. To
adjust the headrest backwards, pull it forward and
release it.
WARNING - Headrests
• To reduce the risk of head and neck
injuries, don't operate the vehicle with
the headrest removed or improperly
positioned.
• For best protection, adjust the headrest
so its center is as high as your ears.
• Do not adjust the driver's headrest while
driving.
