pied by an adult or a
person with a build cor-
responding to that of an
adult.
The classification of the person on the front-passenger seat is
incorrect.

empty

Make sure that the base of the child restraint system rests on
the seat cushion.

When installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight with the front-
passenger seat adjustment. This could result in the seat belt and
the child restraint system being pulled too tightly.

Check that the child restraint system is installed correctly. Make
sure that the head restraint does not apply a load to the child
restraint system. If necessary, adjust the head restraint accord-
ingly.
X
Make sure that no objects are applying additional weight to the
seat.
X
If the PASSENGER AIR BAG OFF indicator lamp remains off and/
or the PASSENGER AIR BAG ON indicator lamp lights up, do not
install a rearward-facing child restraint system on the front-
passenger seat. It is recommended that you fit the restraint
system to a suitable rear seat.
