Seats Safety notes G Warning! In order to avoid possible loss of vehicle control all seat, head restraint, steering wheel, and rear view mirror adjustments, as well as fastening of seat belts, must be done before the vehicle is put into motion. G Warning! Do not adjust the driver’s seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle. Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or fatal injuries. The seat backrest and seat belts provide the best restraint when the wearer is in a position that is as upright as possible and seat belts are properly positioned on the body.

Seats

G Warning! Your seat must be adjusted so that you can correctly fasten your seat belt. Observe the following points: RAdjust the seat backrest until your arms

are slightly angled when holding the steering wheel.

RAdjust the seat to a comfortable seating position that still allows you to reach the accelerator/brake pedal safely. The position should be as far back as possible with the driver still able to operate the controls properly.

RAdjust the head restraint so that it is as

close to the head as possible and the center of the head restraint supports the back of the head at eye level.

RNever place hands under the seat or near

any moving parts while a seat is being adjusted.

Failure to do so could result in an accident and/or serious personal injury. G Warning! The power seats can be operated at any time. Therefore, do not leave children unattended in the vehicle, or with access to

Seats an unlocked vehicle. A child’s unsupervised access to a vehicle could result in an accident and/or serious personal injury. G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. For additional information, see “Children in the vehicle”. A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/or the child is not properly secured in the child restraint. G Warning! For your protection, drive only with properly positioned head restraints. Adjust the head restraint so that it is as close to the head as possible and the center

98

of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation. Do not drive the vehicle without the seat head restraints. Head restraints are intended to help reduce injuries during an accident.

Seat adjustment ! When moving the seats, make sure there are no items in the footwell or behind the seats. Otherwise, you could damage the seats.

Do not fold the second-row middle seat and allow occupants to use the folded second- row middle seat as a footrest while driving. All vehicle occupants must keep both feet on the floor in front of their seat. Otherwise, occupants could slide under the seat belt in a collision. If occupants slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries.

Do not fold the second-row middle seat and allow occupants to use the folded second- row middle seat as a table while driving. Objects placed on the folded second-row middle seat may move freely during braking, vehicle maneuvers, or an accident and be thrown around in the vehicle interior.

The auto-dimming function does not react if incoming light is not aimed directly at sensors in the interior rear view mirror. The interior rear view mirror and the exterior rear view mirror on the driver’s side do not react, for example, when transporting cargo which covers the rear window. Light hitting the mirror(s) at certain angles (incident light) could blind you. As a result, you may not be able to observe traffic conditions and could cause an accident.
