or the safety belts!
With safety belts, you slow down as the vehicle does.You get more time to stop. You stop over more distance,and your strongest bones take the forces. That is whysafety belts make such good sense.
Questions and Answers About
Safety Belts
Q:Will I be trapped in the vehicle after a crash ifI am wearing a safety belt?
A:Youcouldbe — whether you are wearing a safety
belt or not. But your chance of being conscious
during and after an accident, so youcanunbuckle
and get out, ismuchgreater if you are belted.
And you can unbuckle a safety belt, even if you are
upside down.
Q:If my vehicle has airbags, why should I have towear safety belts?
A:Airbags are supplemental systems only; so they
workwithsafety belts — not instead of them.
Whether or not an airbag is provided, all occupants
still have to buckle up to get the most protection.
That is true not only in frontal collisions, but
especially in side and other collisions.
2-16
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for thedriver and right front passenger seating positions.
Adjust the height so that the shoulder portion of the beltis centered on the shoulder. The belt should be awayfrom the face and neck, but not falling off the shoulder.Improper shoulder belt height adjustment couldreduce the effectiveness of the safety belt in a crash.
Press the releasebutton (A) and move theheight adjuster to thedesired position. Theadjuster can be moved upby pushing up on theshoulder belt guide.
After the adjuster is set to the desired position, try tomove it down without pressing the release buttonto make sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for frontoutboard occupants. Although the safety beltpretensioners cannot be seen, they are part of thesafety belt assembly. They can help tighten the safetybelts during the early stages of a moderate to severefrontal or near frontal crash if the threshold conditions forpretensioner activation are met. And, if your vehiclehas side impact airbags, safety belt pretensioners canhelp tighten the safety belts in a side crash.
Pretensioners work only once. If the pretensionersactivate in a crash, they will need to be replaced, andprobably other new parts for the vehicle’s safetybelt system. SeeReplacing Restraint System PartsAfter a Crash on page 2-75.
Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort guidesfor each outside passenger position in the rear seat. Ifnot, they are available through your dealer/retailer. Theguides may provide added safety belt comfort for olderchildren who have outgrown booster seats and for someadults. When installed the comfort guide positions theshoulder belt away from the neck and head.
