When is the best time to begin using the AACE™?
The AACE™ can be used when the child outgrows their harnessed convertible car seat by weight and height, and as long as they can sit with their back against the vehicle seat with their knees bent at the edge of the booster without slouching, and as long as they can sit properly restrained in the seat for long periods of time, and can do this every time.
What is the recommended height and weight for a child using the AACE™ as a high back booster?
Children must meet all of the following criteria:
at least 4 years old, height is between 38"-60" and weight is between 40-110 lbs.
What is the recommended height and weight for a child using the AACE as a no back (backless) booster?
Children must meet all of the following criteria:
at least 5 years old, height is between 38"-60" and weight is between 50-120 lbs.
How much extra shoulder room does my child get?
As your child grows in stature, they need a booster that does the same. You child will get an additional 2" of shoulder room from the lowest headrest position to the highest headrest position.
What are the Lower Anchor Connectors for?
These are for two purposes: 1) they secure your AACE™ seat bottom to the vehicle seat when not in use, making it easier for the child to climb in and out of, 2) allows you to use the recline feature in high back mode.
The lower anchor connectors are not an installation method. The vehicle lap and shoulder belt is how you secure your child.
Do I have to use the SIP protection? (They interfere with the passenger sitting next to my child.)
As instructed, please use the AACE™ with both SIP pods deployed. You may push in the inboard SIP pod if it interferes with an inboard passenger.
Why can't I use recline in the no back booster mode?
It has not been tested and approved for use in that position.
I can't figure out how to pull out my Lower Anchor Connectors. I'm pulling the lever on the seat, but nothing is working.
Are you activating the correct lever, called the "Lower Anchor Release Lever" located on the bottom of the seat? Once you find this, pull and hold the lever, and then rotate and flip the lower connectors out.
How can I keep the shoulder belt from falling off my child's shoulders in the no back mode?
The high back mode provides a shoulder belt guide that properly positions the vehicle shoulder belt across your child's chest and shoulder. When transitioning to the no back mode, you may need to use the shoulder belt positioning clip to obtain proper placement of the vehicle shoulder belt. Please refer to your instruction manual for detailed instructions.
Is there any way to make sure my child can't put the seat belt behind his/her back? Do you sell something that will prevent them from doing this?
Parents should always encourage children to properly wear their seat belt and should demonstrate by setting a good example, by always wearing their seat belt properly. If it becomes a troublesome situation one option is to enable the locking retractor after buckling in your child in the booster seat so the belt cannot be stretched and placed behind the child’s back.
How do I clean my car seat?
You can wipe plastic and metal parts with a damp sponge or soft cloth. You may hand wash or machine wash your covers (seat fabric) on the delicate cycle, using cold water and mild detergent, and always air dry.
The harness system should be cleaned with mild soap and water and allowed to air dry. Wipe the outside of the buckle with a damp cloth. Do not lubricate the buckle or immerse in water.
Do not use bleach or harsh chemicals on your car seat and do not dry clean. Use of cleaning agents such as these can damage your car seat and cause deterioration of the materials.
Does my AACE™ have an expiration date?
Yes. The expiration date or useful life of the AACE™ is 10 years after the date of purchase. If you are unsure of the date of purchase you can also use the date of manufacture. The date of manufacture information can be found on the bottom of your car seat.
Do I have to replace my AACE™ if it has been involved in a car accident? What if it was a minor accident, ie: fender bender?
If you have been involved in a minor crash then we recommend you follow the NHTSA guidelines:
NHTSA recommends that car seats be replaced following a moderate or severe crash in order to ensure a continued high level of crash protection for child passengers. Car seats do not automatically need to be replaced following a minor crash.
What defines a minor crash?
A minor crash is one in which ALL of the following apply:
• The vehicle was able to be driven away from the crash site.
• The vehicle door nearest the car seat was not damaged.
• None of the passengers in the vehicle sustained any injuries in the crash.
• If the vehicle has airbags, the airbags did not deploy during the crash; and
• There is no visible damage to the car seat.
NEVER use a car seat that has been involved in a moderate to severe crash. Always follow manufacturer's instructions.
Can I use the AACE™ booster on an airplane?
The AACE™ is not certified for aircraft use. Airplane seats have only a lap belt and the AACE must be used with a Lap/Shoulder Belt.
Can I use an inflatable seat belt?
Can the AACE™ recline be used without the Lower Anchor Connectors?
No, you must use the Lower Anchor Connectors to secure your AACE™ to the vehicle seat to utilize the recline feature in high back mode.
Do I have to install my AACE™ with Lower Anchors?
The AACE™ Lower Anchor system is not necessary to use the booster in the high back or no back modes. This feature is a convenience feature that ensures the seat stays in place when the child is not buckled into the seat.
There are several restrictions however; to use the recline feature of the high back booster mode, the seat must be anchored in with the lower anchors.
When the booster is being used without the back and utilizing the lower anchors, the AACE™ must be pushed back so the back of the booster is against the vehicle’s seat back. No space should be left between the seat bottom and the back of the vehicle seat.
Does the cupholder have BPA or phthalates?
No, the AACE™ cupholders do not have BPA or phthalates.
Can my child wear winter coats in the AACE™?
No. Wearing bulky clothing can prevent a proper seat belt fit. A large “puffy” coat or clothing can compress in a crash introducing slack into the seat belt which need to stay tight on the child. You should not put your child in any car seat wearing bulky clothing or jackets. Instead, remove any bulky clothing and cover your child with a blanket or jacket after securing your child in the seat.
We do not recommend using any products or accessories that are not approved by Nuna.
Where can I find my product / serial label on the AACE™?
The product serial label can be found underneath the car seat on the frame of the AACE™.
