cluster displayPractical hints Car care Index Seat belt nonusage warning system
With the key in steering lock position 2, a warning
sounds for a short time if the driver’s seat belt is not
fastened.
Wa r n i n g !
Failure to wear and properly fasten and position
your seat belt greatly increases your risk of
injuries and their likely severity in an accident.
You and your passenger should always wear seat
belts.If you are ever in an accident, your injuries can be
considerably more severe without your seat belt
properly buckled. Without your seat belt buckled,
you are much more likely to hit the interior of the
vehicle or be ejected from it. You can be seriously
injured or killed.In the same crash, the possibility for injury or
death is lessened if you are wearing your seat belt.
Wa r n i n g !
Never let more people ride in the vehicle than there
are seat belts available. Be sure everyone riding in
the vehicle is correctly restrained with a separate
seat belt.
