SAFETY
||
WARNING
A child seat should never be used in the front
passenger seat of any vehicle with a front
passenger airbag - not even if the "Passenger
airbag off" symbol near the rear-view mirror is
illuminated. If the severity of an accident were
to cause the airbag to inflate, this could lead
to serious injury or death to a child seated in
this position.
3.
Fasten the seat belt.
Fasten the seat belt by inserting the latch
plate into the buckle (lock) until a distinct
click is audible.

Pull out the shoulder section of the seat belt.
4. Pull the shoulder section of the seat belt out
as far as possible to activate the belt's auto-
matic locking function.
NOTE
The locking retractor will automatically
release when the seat belt is unbuckled and
allowed to retract fully.
5. Press the infant seat firmly in place, let the
seat belt retract and pull it taut. A sound from
the seat belt retractor's automatic locking
function will be audible at this time and is
normal. The seat belt should now be locked
in place.
Check that the infant seat is properly secured.
6. Press and pull the infant seat along the
direction of the seat belt to check that it is
properly held in place by the seat belt.
