Is there a way to replace the strap that attaches to the back of the car seat? Mine was torn off at the airport when flying out of town.

install an anchor behind the seat or install two of them, located equi-distant from the seat location on both sides but behind. The strap loops on the seat are for nylon straps with buckles. Attach to seat and attach straps in rear to anchors. You'll need pop-rivet tool to attach the anchors and if your seat is decent quality, it should have straps sewn-into it on the edges. Be sure to use a good seat-back with an area of padding to sit yourself onto. Life gets uncomfortable without a padded seat bottom!

you need to provide more information (type of car seat, model of car) for an accurate answer, however:
most (if not all) car seats made these days have a ******** either side with a clip like this on the end (http://www.babysafetycarseat.info/wp-content/uploads/Car%20Seat%20Latch.jpg) which attaches to two hooks located between the seat cushion and the back cushion (http://autostol.info/wp-content/uploads/2010/08/Isofix-voorbeeld-11.jpg).
simply attach the clips to hooks, put your weight on the car seat while pulling the straps tight, and you're done.

Car straps to attach to car of the straps on the car seat?
If it's to attach to the car, feel in the back seats where they join together (seat to backrest area) and you should feel some hooks in there.

Yeah its a bit tricky. ON the fron of the car seat there is a strap that goes intot he seat and has a button to lossen it. Press it down to lossen that strap then flip seat over and on the bottom you will find other end of the same strap and it has a brass t-fitting. Take it and pull it up the back side of seat and the shoulder straps fit into the brass fitting then tighten by pulling strap in front of chair.

HAve fun ;)

Just go to the maxi cosi website and call the contact number. Or you can dowload the online usermanual, it has a order form.

I have the same seats. All you have to do is pull the small teather stap at the top of the child booster seat. You pull it to make it tighter around the child or you pull it and then pull the child saftey straps at the same time. You also do not have to purchase the manual if you call chrysler they will send you one for free. That is how I got mine.

Are you sure you're looking at the UAS/LATCH strap and not the top tether?
Your seats should have a long strap with a hook at each end that goes through the belt path (the UAS strap) and another at the top, for top tethering once you turn them forward facing.
The UAS strap may be hooked onto the sides of the seat or bundled together underneath...take another look at your manual to find out where they store it.
Alternately, install with the seat belt - neither LATCH/UAS or seat belt is "safer" than the other...the LATCH/UAS is just supposed to be more convenient.

how do i put the straps back on through the cover

I had trouble getting mine tight too and my sister said what she did was kneel in the seat and then pull up on the strap. I tried that and it worked! I think it pushes the seat down more so that you have more strap to pull.
