Essential Safety Equipment
Seat Belt Systems
Do not operate a vehicle with a damaged seat belt:
Using a damaged seat belt is dangerous. An accident could damage the belt webbing
of the seat belt in use. A damaged seat belt cannot provide adequate protection in a
collision. Have an expert repairer, we recommend an Authorised Mazda Repairer
inspect all seat belt systems in use during an accident before they are used again.
Have your seat belts changed immediately if the pretensioner or load limiter has been
expended:
Always have an expert repairer, we recommend an Authorised Mazda Repairer
immediately inspect the front seat belt pretensioners and air bags after any collision.
Like the air bags, the front seat belt pretensioners and load limiters will only function
once and must be replaced after any collision that caused them to deploy. If the
front seat belt pretensioners and load limiters are not replaced, the risk of injury in a
collision will increase.
Positioning the Shoulder Portion of the Seat Belt:
Improper positioning of the shoulder portion of the seat belt is dangerous. Always make
sure the shoulder portion of the seat belt is positioned across your shoulder and near
your neck, but never under your arm, on your neck, or on your upper arm.
Positioning the Lap Portion of the Seat Belt:
The lap portion of the seat belt worn too high is dangerous. In a collision, this would
concentrate the impact force directly on the abdominal area, causing serious injury.
Wear the lap portion of the belt snugly and as low as possible.
