is the seat beltsystem.
If you install achild restraintsystem onthe
front passenger seat,besure toobserve the
instr uctions andsafety noteson the "Occu-

All child restraintsystems mustmeet thefol-
lowing standards:
R U.S. Federal MotorVehicle SafetyStandards
213 and225
R Canadian MotorVehicle SafetyStandards
213 and210. 2
Confirmation thatthechild restraintsystem
correspon dstothe standards canbefound on
an instr uction labelonthe child restraintsys-
tem. Thisconfirmation canalso befound in
the installation instructions thatareincluded
with thechild restraintsystem.
Observe thewarning labelsinthe vehicle inte-
