GWARNING
If the driver's seat is not engaged, it could
move forwards as far as the next catch dur-
ing movement such as braking or abrupt
changes of direction. As a result, you would
be pushed against your seat belt by the
unsecured driver's seat.
This could cause you to lose control of the
vehicle. The seat belt cannot protect as
intended and could result in additional
injury.
There is a risk of an accident and injury.
Before every journey, make sure that the
driver's seat is fully engaged.
