REAR SEATS (IF EQUIPPED)
Non-adjustable head restraints
Your vehicle is equipped with second row outboard non-adjustable head
restraints. The head restraints can be rotated forward to improve rear
vision when there are no rear occupants.
WARNING: To minimize the risk of neck injury in the event of a
crash, the driver and passenger occupants should not sit in
and/or operate the vehicle, until the head restraint is placed in its
proper position. The driver should never adjust the head restraint
while the vehicle is in motion.
The non-adjustable head restraints
consist of :
• a trimmed energy absorbing foam
and structure (1),
• and a rotation button (2),
Properly adjust the head restraint to an upright driving/riding position by
lifting up on the head restraint until it locks into its original position.
