Britax MARATHON 70 - Manual (Page 30)

Before You Begin:
• Check that your vehicle has lower anchors.
* Refer to your vehicle owner’s manual or contact the vehicle
manufacturer for the maximum weight rating for their lower
anchors. Use vehicle belt (not lower connectors) for installations
with children who weigh more than the vehicle lower anchor limit.
Unless specified otherwise by the vehicle manufacturer, assume a
40 pound (18.1 kg) child is the vehicle lower anchor limit.
• Remove the lower connectors from the storage slots in the base.
Press the adjuster release button and pull the strap to full length.
Repeat for the second strap.
• This child seat must be reclined to position 3 and placed
rear-facing on the vehicle seat.
* 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 blue line as a guide
to achieve the proper recline angle for
rear-facing installations. The blue line will be
parallel to the ground when the child seat angle is at the center
of the angle range (30 – 45˚). If necessary, the proper recline
angle can be achieved by placing a rolled towel or pool noodle
in the vehicle seat bight.
• Britax recommends that the Versa-Tether is used at all times. Using
the tether will improve the stability of the child seat and reduce the
risk of injury. Check your vehicle owner’s manual for tether anchor
locations. See page 25 for possible rear-facing tether configurations.
