You can call the manufacturer, Dorel Juvenile Group, at (800) 219-0509, and they will advise you what to do. A carseat with twisted straps is not safe, especiallyif they involve the harness.

Make sure you also check to see if your AOE is one of the ones recalled for harness issues; if so, the Dorel Juvenile Group will send you a free repair kit.

SOURCE: took seat apart to wash, can't figure out how to

I would look on the car seat and find out what company makes it or a phone number for them. They might be able to walk you thru how to relace the straps or most companies will send you a new manual for free (might have to pay S&H)

SOURCE: Someone removed all harness from my Cosco, Summit

My daughter has a car seat just like this one, and I wash it about once a month so I hope I can explain this detailed. First, at the base there is a metal rod that will need removed. When you take this rod out the base and seat will seperate. Set base aside and turn seat upside down. Take your strap and put an end into each slot. Turn seat over and pull your straps even. Put the two black pieces for your latch on (one on each side) then put you chest pieces on and run straps thru slots on back of seat. Turn seat around and make sure the straps go OVER the silver bar in back (this allows you to adjust shoulder height) Secure to the metal piece that runs to front for tightening adjustment. Sey seat back on base and replace rod. Hope this was helpful.

Need new straps for maxi cosi tobi

Hi Mandy

Due to the safety implications of a carseat harness being incorrectly fitted we are unable to supply a harness to you as a spare part item.

To replace the harness the carseat would need to come in for our engineers to provide replacement and safety checks to ensure product is working as per specification. 1924a6a3-e420-4f10-b6df-f9a1deebe867.jpg

How to remove maxi cosi priorfix harness straps

Hi Deirdre

Due to the safety implications of the harness in your carseat being incorrectly fitted we must recommend that you do not attempt to remove or replace the harness yourself.

Should you wish to have it replaced you can send the seat to our engineers for inspection and replacement of the harness plus safety checks to confirm that it is working as per specification. 5bac1756-b7e9-4806-aa74-da8d8a038fa4.jpg

How to remove maxi cosi cabrio harness straps


The harness of a carseat should never be removed or replaced by anyone other than a trained engineer due to the safety implications of it being incorrectly replaced.

The carseat fabric should be removed from this carseat and they can be washed - the harness itself should be cleaned in place in the carseat using a solution of stain remover and water and a small scrubbing brush or hard scourering pad to clean the harness. Excess water in the carseat should be dried immediately and thoroughly to prevent any parts rusting. Loose crumbs can be removed using a vacuum cleaner.

Alternatively the carseat can be sent in for the engineers to replace with a new one. Inspection and single repair (replacement of the harness) plus safety checks and courier collection and repair can be booked for 39.99GBP if you're in the UK by calling 01284 413 141 Mon-Thur 8.30-6.30 / Fri 8.30-4.30 (Excluding Bank Holidays)

Good Afternoon

The harness straps should not have been completely removed from the carseat - you do not have to do this in order to remove the fabrics for washing. We cannot advise that you re-thread the harness yourself due to the safety implications of it being incorrectly done. This carseat should be sent to our engineers for them to carry out this work and for full safety checks to be done before it is used again.

If you are in the UK please contact our customer service department on 01284 413 141 Mon-Fri 8.30-4.30 and have a chat with one of the advisors about this.

I dissasembled the car seat so I need get manual in order to re-assebly the belts in the correct way , can you help me

I just noticed my car seat had a safety recall back in 2007 and noticed you had the same recall on the 22150. I just ordered a new kit from Cosco (which was free) to replace the faulty parts. Here's the recall notice ans website to go to:
Click on "Harness Adjustment Strap Inspection" and give your info. to order the kit.

Dorel Juvenile Group Announces a Voluntary Safety Recall of the Harness Adjustment ******** Certain Cosco®, Safety 1st® and Eddie Bauer® Brand Child Restraint Systems
Columbus, IN August 30, 2007- Dorel Juvenile Group (DJG) is issuing a voluntary safety recall for certain Cosco®, Safety 1st® and Eddie Bauer® brand child restraint systems manufactured during November 2003 through December 2005. Although no injuries have been reported, there is a potential for the harness adjustment strap to loosen during use. If this were to occur, the harness may be loose around the child, possibly increasing the risk of injury in a crash. We feel that it is important to replace the harness adjustment strap.

Model numbers affected are:
Cosco®: Alpha Omega®, Alpha Omega EliteTM: 22150, 22155, 22180, 22269; Eddie Bauer®: 3-in-1, Deluxe 3-in-1, Deluxe Convertible: 22740, 22750, 22755, 22756, 22757, 22770; Safety 1st® : Alpha EliteTM, Alpha Omega®, Alpha Omega EliteTM, Alpha SportTM, InteraTM, EnspiraTM: 22151, 22450, 22451, 22452, 22453, 22455, 22460, 22480, 22481

The model number and date of manufacture may be found on a sticker located on the side or back of the child restraint system.

DJG will contact all registered owners and provide them with information on how to obtain a free repair kit to replace the harness adjustment strap. Those consumers who have not registered their product should visit or call 800-219-0509 to order a free repair kit. The affected seats should not be returned to the retailer.

DJG encourages parents to obtain and install the repair kit as soon as possible. Parents may continue to use the child restraint system as directed in their instruction manual. Parents should be sure to adjust the harness adjuster strap snugly each time they put their child in the child restraint system. If there is any difficulty adjusting the harness adjustment strap, or it does not remain tight, DJG suggests using a different child restraint system until the repair kit has been installed.

To check for harness slippage:
(1) Fully tighten the harness, (2) pull on the harness straps without pressing or lifting the harness adjustment lever. If movement occurs, the harness is experiencing slippage.

How to change the Safety 1st "Alpha Omega Elite" to a booster

To change it into a belt positioning booster seat, you remove the harness straps completely and use the positioning clips on the side of the carseat (up by the head) to position the automobile's seat belt to the appropriate position.
