EXEC™ All-In-One Car Seat FAQ


What are the age and size limits for the EXEC™?

The EXEC™ was designed for children from 5 to 120 lbs., and whose height is less than 57".

• Rear-Facing: Children can ride rear-facing from 5 to 50 lbs. using the Vehicle Seat Belt, and 5 to 35 lbs. using the Lower Anchors (LATCH). 49" maximum.

• Forward-Facing: Children can ride forward-facing from 25 lbs. to 65 lbs. using the Vehicle Seat Belt, and 25 to 40 lbs. using the Lower Anchors (LATCH). 49" maximum.

• Booster: Children can ride forward facing from 40 lbs. to 120 lbs. using the Vehicle Seat Belt. 38"-57", 4 y/o minimum.

When should I use the infant insert and infant head insert?

The infant insert can be used for a child that is 5 lbs. and if the harness straps are positioned ABOVE the child’s shoulders in the 2 lowest sets of harness slots.

The harness must fall AT OR BELOW the child’s shoulders. The infant insert can be used up to 11 lbs.

The head insert may be used or removed for improved comfort to child at any time.

How long should my child ride rear facing? Why?

Nuna and the American Academy of Pediatrics recommend children ride rear-facing until they are at least 2 years old. Most children meet the weight and height requirement to ride rear facing in the EXEC™ for longer than 2 years. We encourage you to keep your child rear-facing in EXEC™ as long as the child fits and is within the maximum rear-facing requirements for both height and weight.

Is it dangerous or uncomfortable for my child's legs to be touching the back of the vehicle seat when rear facing?

Though it may seem uncomfortable to you, children are more flexible than adults. Children will find different leg positions to make themselves comfortable, from crisscross, to putting their legs straight, to hanging them over the sides of the car seat. These are all acceptable riding positions.

There is no data that shows when a child's feet or legs reach the vehicle seat that they are at an increased risk for lower-extremity injuries. It is much more important to protect the head, neck and spine during a crash - which is what riding rear facing does.

When can my child be turned around to face forward?

We recommend children ride rear facing as long as their weight and height are within the rear-facing requirements, and until at least 2 years of age.

Children can safely ride forward-facing when they weigh 25 lbs., and are at least 2 years old.

When I install the EXEC™ forward facing and reclined, the front of the seat hangs over the vehicle seat. Is that ok?

20% of the EXEC™ can hangover the vehicle seat.

My child has exceeded either the weight or height limit of EXEC™, but not both. Can I continue using the EXEC™?

To use the EXEC™, your child must be within BOTH the height and weight requirements. If your child exceeds the usage requirements for forward-facing, he or she may be ready for a belt-positioning booster like the Nuna AACE™. The AACE™ starts at 4 years old, 40 lbs. and 38" in the high back booster mode.

Do I have to use the harness or hip covers, or the crotch belt cover?

The EXEC™ harness covers must be utilized only when the child is rear-facing.

Forward-facing the harness covers may be removed or used based on your child's comfort.

What is the difference between installing with a Vehicle Seat Belt vs. LATCH (Lower Anchor Belt)?

There is no installation difference. Both methods of installation are safe and have been tested and pass the FMVSS 213 standard. As you install your car seat you may find the ease of use of one easier or harder than the other depending on vehicle and ability. The Vehicle Seat Belt can hold a higher weight limit than the Vehicle Lower Anchorage system. The vehicle's Lower Anchorage System can only hold a maximum of 65 pounds TOTAL. This is calculated by adding the child's weight + weight of the EXEC™ car seat. (Consult instruction manual, "Child Usage Requirements" for details.)

Rear-Facing: Do not use the Lower Anchors (LATCH system) for a child weighing more than 35 lbs. (15.8 kg)

Forward Facing: Do not use the Lower Anchors (LATCH system) for a child weighing more than 40 lbs. (18.1 kg)

Why does Nuna prefer the vehicle seat belt installation rather than the Lower Anchor Belts (LATCH) installation?

Both methods of installation are safe and have been tested and pass the FMVSS 213 standard. Nuna's preferred installation method is the Vehicle Seat Belt because 1) it eliminates confusion of when to switch from Lower Anchor Belts to Vehicle seat belt, 2) all vehicle seating positions are manufactured with a seat belt but not all vehicle seating positions include Lower Anchor Belts/LATCH, and 3) you can install the EXEC™ in more seating positions with a vehicle seat belt install.

Always use Tether for forward facing installations if your vehicle is equipped with a Tether Anchor point and vehicle requirements are met (see vehicle owner's manual).

Can I install EXEC™ with both the Vehicle Seat Belt and Lower Anchor Belts (LATCH)?

The EXEC™ can only be installed using 1 method; either the Vehicle Seat Belt or Lower Anchor Belt.  Always use Tether for forward-facing installations if your vehicle is equipped with a Tether Anchor point and vehicle requirements are met (see vehicle owner's manual).

Do I need a locking clip?

The EXEC™ True Tension door applies tension to the vehicle seat belt. The EXEC™ must always be used with a locking vehicle belt system, to ensure a secure installation in every vehicle. To be sure your car is equipped with a locking vehicle belt or locking latch plate, consult your vehicle owner's manual. If your car does not have a locking vehicle belt or locking latch plate, we can also provide you with a locking clip.

How many EXEC™ or Nuna car seats can fit in my vehicle?

We found that the EXEC™ will fit three across in most midsize vehicles. Every vehicle is designed differently and the ability to fit several seats in the same row depends on the size and configuration of your vehicle's seating system. The larger the vehicle the more seats can be fit in the vehicle.  In some vehicles, we found that PIPA™, RAVA™ & AACE ™ will fit in one row!

Can I use a seat protector under my EXEC™ to protect my vehicle seat?

The EXEC™ was designed with a smooth seat back and seat bottom, so using a vehicle seat protector is not necessary. We do not recommend using any products or accessories that are not approved by Nuna. Adding a product or accessory could alter the effectiveness or performance of the EXEC™ if ever involved in a crash.

How do I clean my car seat?

You can wipe plastic, vinyl, and metal parts with a damp sponge or soft cloth.

The seat fabric can be machine washed on a delicate cycle with cold water, mild detergent, and then air dried.

The harness system should be cleaned with mild soap and water and allowed to air dry. Do not attempt to remove the harness system. 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.

How do I remove my cupholder?

Both cupholders can be removed by rotating the cupholder into the use position, and then firmly pulling up. Replace the cupholder by snapping the cupholder onto the hinge. Be sure cupholder is securely attached.

The harness straps are dirty, destroyed, etc. Can I replace them?

The harness straps are an integral part of the child restraint, you must replace the seat frame if the harness becomes unusable.


Do I have to replace my EXEC™ 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 an inflatable seat belt?

The EXEC™ cannot be installed using a self-inflatable vehicle seat belt. If the only seat belt options in the vehicle are inflatable seat belts, you must install the EXEC™ using the Lower Anchor Belts (LATCH).

Where can I find my product / serial label on the EXEC™?

The product serial label can be found underneath the car seat on the frame of the EXEC™.
