Seat Modes: Harness/ High Back/ No Back Booster

* Use body insert for smaller child, but never in booster mode.
* from manual: ""We highlight recommend using the built in safety harness for as long as possible when the child is 70 lbs or less and the shoulders are below the harness slots in the highest position.""
* LATCH weight limit (unless the vehicle otherwise specifies): 50 pounds
* 3 recline positions, all can be used in harness mode
* ""The car seat MUST NOT hang over the edge of the vehicle seat.""
* ""Vehicle seat headrest MUST NOT create a gap between the vehicle seat and the booster seat.""
* Long belt path is required if there is a lap belt only with no tether and the child Is under 30 pounds. (a lot more on this later)
* On one page it says ""harness strap covers must always be used with the harness. "" but then later it says ""if they interfere with the correct placement of the chest clip at armpit level, remove them from the harness straps and do not use until the child grows and they no longer interfere."" So I have no idea what the rule is.
* LATCH and top tether can be used in booster mode.
* LATCH installation is strongly preferred and recommended if available
