Using A Lock-Off; Infant Positioning Pillow; Seat Positions - Britax MARATHON Guide D'utilisation

BRITAX Child Safety, Inc.

Using a Lock-Off

NOTE: Using a lock-off is optional if your vehicle seat belt
system has a locking feature. See pages 31-34 and your
vehicle owner's manual for more information.
To Open:
1. Open the locking tab.
2. Open the clamp.
IMPORTANT: Both parts
of the lock-off must be
opened to secure a vehicle
belt.
To Close:
1. Close the clamp over the
vehicle belt.
2. Push down on the locking
tab where indicated until
a click is heard.

Infant Positioning Pillow

The infant positioning pillow is designed to provide better
harness fit and comfort for infants using this child seat.
IMPORTANT: The infant
positioning pillow must be
used with infants weighing up
to 10 kg (22 lbs) when using
a child seat in a rear-facing
position. Do not use over 10 kg
(22 lbs) or in a forward-facing
position.

Seat Positions

This child seat has 3 positions. To adjust, pull the recline
handle then rotate the child seat shell into the desired
position. Release the recline handle, then verify the child
seat has locked into position.
NOTE: Set the seat position BEFORE installing.

Rear-Facing
When properly installed in the rear-
facing position, the back angle of the
child seat should be at least 30˚ for
children and up to 45˚ from vertical for
infants unable to maintain head and
neck control (not to exceed 45˚) when
the car is parked on a level surface.
Use the line as a guide to achieve the proper recline angle
for rear-facing installations. The line will be parallel to the
ground when the child seat angle is at the center of the
acceptable angle range (37.5˚). If necessary, the proper
recline angle can be achieved by placing a rolled towel or
pool noodle in the vehicle seat bight.
Overhang
It is important that
the base of the child
seat rests completely
flat on the vehicle
seat. As seen in
the illustration, it is
permissible to allow
up to 7.6 cm (3 in.)
of the base to hang
over the edge of the
vehicle seat. Some
Forward Facing
vehicle seats do not
allow enough of the child seat base to contact the vehicle
seat. If this is the case for a forward-facing installation, adjust
the seat to the upright position. For a rear-facing installation,
choose another seating position. Not doing so could cause
the child seat to not perform as intended.
In some cases, the vehicle head
restraint can prevent the child seat
head pad from being raised high
enough to properly adjust the harness
for the fit of your child when using a
forward facing reclined position. DO
NOT force the child seat head pad
past the vehicle head restraint. Doing
so could cause the child seat not to perform as intended.
If the location of the vehicle head restraint interferes with
the child seat head pad, raise or remove the vehicle head
restraint. If the vehicle head restraint cannot be removed,
move the child seat to the upright position or try a
different seating location.
