G
WARNING
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position shoulder belt across the chest and
shoulder, not face or neck.
In
order to attain the correct seating position
for children weighing over 41 lb (18 kg), it may
be necessary to use a booster seat until they
reach a height where a normal lap/shoulder
seat belt lies properly across their bodies
without the need for a booster seat.
Install the child restraint system according to
the manufacturer's instructions.
The child restraint system must be installed
firmly on both brackets.
An incorrectly installed child restraint system
can come loose in the event of an accident,
causing the child to be severely or fatally
injured.
Child restraint systems/child restraint
retaining brackets that are damaged or have
suffered damage due to an impact must be
replaced.
LATCH-type (ISOFIX) is a standardized
securing system for specially designed child
restraint systems on the rear seats. Securing
rings for two LATCH-type (ISOFIX) child
restraint systems are installed on the left and
right of the rear seats.
Secure non LATCH-type (ISOFIX) child
restraint systems using the vehicle's seat belt
system. Always install child restraint systems
according to the manufacturer's instructions.

the
window pane when opening a window. The
downward motion of the pane may pull that
part of your body down between the window
pane and the door frame and trap it there. If
there is a risk of entrapment, release the
