1. Turn the vehicle off.
2. Remove the child restraint
from the vehicle.
3. Remove any additional
items from the seat such as
blankets, cushions, seat
covers, seat heaters,
or seat massagers.
4. Reinstall the child restraint
following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Front Seat) 0 90
or Securing Child Restraints
(With the Seat Belt in the
Rear Seat) 0 88.
Make sure the seat belt
retractor is locked by pulling
the shoulder belt all the way
out of the retractor when
installing the child restraint,
even if the child restraint is
equipped with a seat belt
lock off. When the retractor
lock is set, the belt can be
tightened but not pulled out
of the retractor.
5. If, after reinstalling the child
restraint and restarting the
vehicle, the ON indicator is
still lit, turn the vehicle off.
Then slightly recline the
vehicle seatback and adjust
the seat cushion,
if adjustable, to make sure
that the vehicle seatback is
not pushing the child
restraint into the seat
cushion.
Also make sure the child
restraint is not trapped
under the vehicle head
restraint. If this happens,
adjust the head restraint.
See Head Restraints 0 38.
6. Restart the vehicle.

child restraint depending upon
the child s size. It is better to
secure the child restraint in a
rear seat. Never put a
rear-facing child restraint in
the front seat, even if the ON
indicator is not lit.
