Move seat fully back
A forwardfacing child restraint sys-
tem should be allowed to be
installed on the front passenger
seat only when it is unavoidable.
Always move the seat as far back
as possible, because the force of
the deploying front passenger air-
bag could cause death or serious
injury to the child.
On vehicles with side airbags, do
not allow the child to lean against
the front door or around the front
door even if the child is seated in
the child restraint system. It is dan-
gerous if the side airbags inflate,
because the impact could cause
death or serious injury to the child.
Do not install a child restraint sys-
tem on the second (or third) seat if
it interferes with the lock mecha-
nism of the front (or second) seats.
This can cause death or serious in-
jury to the child and passengers
sitting in front (or second) seats in
case of a sudden braking or a colli-
sion.
If the driver ’s seat position does
not allow sufficient space for safe
installation, install the child re-
straint system on the second right
seat.
