Seats Safety notes G Warning! In order to avoid possible loss of vehicle control the following must be done before the vehicle is put into motion: Rseat adjustment Rhead restraint adjustment Rsteering wheel adjustment Rrear view mirror adjustment Rfastening of seat belts 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. 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. The center of the head restraint must support 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 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 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.

Auto-dimming rear view mirrors The exterior rear view mirror on the driver’s side and the interior rear view mirror will respond automatically to glare when the ignition is switched on and incoming light from headlamps falls on the sensor in the interior rear view mirror. The rear view mirrors will not react if the automatic transmission is set to reverse gear R or the interior lighting is switched on. G Warning! 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, if the rear window sunshade is in raised position. 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.
