.Do not tow a trailer.
.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant.

roadside so that you do not
obstruct the flow of traffic and
so that you are able to seal the flat
tire without being in danger.
.Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the vehi-
cle will not move.
