2004 HONDA S2000 check engine

If a seat belt does not seem to work
as it should, it may not protect the
occupant in a crash.Using a seat
belt that is not working properly can
result in serious injury or death.
Have your Honda dealer check the
belt as soon as possible.
See page f or additional
inf ormation about your seat belts
and how to take care of them. After occupants have adjusted their
seats and put on seat belts, it is very
important that they continue to sit
upright, well back in their seats, with
their feet on the floor, until the
vehicle is parked and the engine is
off.
Sitting improperly can increase the
chance of injury during a crash. For
example, if an occupant slouches,
lies down, turns sideways, sits
forward, leans forward or sideways,
or puts one or both f eet up, the
chance of injury during a crash is
greatly increased.
In addition, an occupant who is out of
position can be seriously or f atally
injured in a crash by striking interior
parts of the vehicle, or being struck
by an inflating front airbag.

The build-up of snow or mud on
your vehicle’s underside adds
weight and rolling resistance.
Frequent cleaning helps your f uel
