WARNING! Use your Hazard Flasher Warning
System any time you have to stop off the road or
on the side of the road, day or night. A hard-tosee
vehicle can result in an injury accident.
Another vehicle could run into you if you do not
set your flashers and follow the placement of
emergency signals per FMCSR 392.22. Always
move the vehicle a safe distance off the road
when stalled or stopped for repairs. A disabled
vehicle can be dangerous for you and others.
The hot exhaust system could ignite dry
grass, spilled fuel, or other substances. Do
not park or operate your vehicle where the
exhaust system could contact dry grass,
brush, spilled fuel, or any other material that
could cause a fire.
