Diono Monterey® 5iST FixSafe™ Story

What comes in the box?

Monterey® 5iST FixSafe™ Booster, Instruction Manual, Cup Holder, Carry Strap x2

When is my child ready for a booster seat?

Diono booster seats can be used for children weighing 40-120 lbs. (18-54 kg) and are 38-63 in. (96.5-160 cm) tall. Typically once a child reaches 5 years of age they are mature enough to ride in a booster seat.

Does it have a steel core?

The Monterey® 5iST FixSafe™ is the only booster with a steel core.

Will the booster seat fit 3 across in my car?

Our booster seats fit 2 across in most cars. Each vehicle model is different and allows for various seating positions. Consumers should consult vehicle owners manual for appropriate car seat placement in their car that may fit more than 2 across.

Which booster seats come with cupholders?

Solana® comes with fabric cup holders in the cover. Solana® 2, Cambria® 2, Monterey® XT, Monterey® 2XT, and Monterey® 4DXT come with two retractable cup holders. The Monterey® 5iST FixSafe™ includes a Radian® cupholder with easy snap in installation.

How do you install the Monterey® 5iST FixSafe™ with the rigid LATCH?

Press the LATCH release button on the front of the booster. Attach the LATCH connectors to the vehicle’s lower anchors. Confirm the connector’s lock indicator changes from red to green. Push the seat backward until it touches the vehicle seat back.

Can I use the Monterey® 5iST FixSafe™ if I don’t have a latch system?

Yes, it can be used without the LATCH. They will need to use the shoulder seat belt to hold the seat in place when not in use to prevent it from becoming a flying object during a crash or sudden stop.

How do I make it into a backpack with the strap?

Locate the straps included with the car seat accessories. Attach the straps to the fabric loops on the back of the seat. Next adjust the straps for comfort before use.

Can I use them on flights?

Diono booster seats are not meant to be used on airplane. Boosters require a lap/shoulder belt and airplanes only have a lap belt.

When does my booster seat expire?

All Diono booster seats have a life span of 8 years, starting from the date you purchase your seat. In the event the date of purchase cannot be determined then we use the date of manufacture.

How do you uninstall the Monterey® 5iST FixSafe™ Rigid LATCH?

Press the LATCH release button located on the front of the car seat and pull the car seat away from the vehicle backseat.

Do Diono's booster car seats work with Ford's inflatable seatbelts?

Please consult the seat manual. Diono Cambria and Monterey seats manufactured prior to 2017 can be used with Ford's inflatable seat belts. Newer models will not allow them to be used and will be stated in the car seat's manual.
