Installation Guide
This section details how to securely install the Primo Viaggio 4-35, covering base installation, vehicle belt-only methods, and utilizing color-coded belt paths for simplified setup.
Installing with the Base
Using the base significantly simplifies and enhances the safety of the Primo Viaggio 4-35 installation. Begin by ensuring the base is correctly positioned in the vehicle seat, following all vehicle manufacturer instructions. Confirm the base is level; many bases include an indicator for this purpose.
Extend the vehicle’s lower anchors or use the seatbelt, threading it through the designated belt paths on the base – Peg Perego utilizes color-coding to aid in correct routing. Tighten the belt securely, ensuring minimal movement of the base (less than one inch side-to-side or front-to-back).
The base features a locking mechanism; verify it’s engaged. Finally, securely attach the Primo Viaggio 4-35 car seat to the base, listening for a distinct click indicating a proper connection. Always double-check the connection before each journey. Refer to page 27 for unlatching instructions.
Installing Without the Base (Vehicle Belt Installation)
The Primo Viaggio 4-35 is certified for installation directly with the vehicle’s safety belt, offering flexibility when a base isn’t available. Begin by positioning the car seat securely in the vehicle seat, rear-facing as required for infants. Thread the vehicle’s seatbelt through the correct belt path – Peg Perego employs color-coded guides for ease of use.
Ensure the belt lies flat and isn’t twisted. Tighten the seatbelt firmly, eliminating any slack. A firm installation is crucial; the seat should not move more than one inch side-to-side or front-to-back.

Confirm the locking mechanism of the seatbelt is engaged – consult your vehicle’s manual for specifics. Always re-check the installation before each trip. While convenient, using the base is recommended for simpler and potentially safer installation.
Color-Coded Belt Paths for Easy Installation
Peg Perego simplifies car seat installation with a user-friendly color-coding system on both the Primo Viaggio 4-35 and its compatible base. This intuitive design guides parents through the correct routing of the vehicle’s seatbelt, whether installing with or without the base.
Distinct colors indicate the proper path for the belt, minimizing confusion and reducing the risk of incorrect installation. The seat and handlebar feature these color-coded guides, ensuring clarity. Following these visual cues is vital for achieving a secure and stable fit.
Always double-check that the seatbelt is threaded correctly according to the color-coded instructions before tightening. This feature significantly enhances the ease and accuracy of installation, contributing to enhanced child safety.
Base Compatibility
The Peg Perego Primo Viaggio 4-35 is designed for versatile use, offering compatibility with a range of bases for convenient installation. While certified for use without a base utilizing the vehicle’s seatbelt system, employing a compatible base is highly recommended for simplified and safer installation.
The car seat securely attaches directly to all Peg Perego bases, ensuring a snug and stable fit. Utilizing a base provides added convenience for quick and easy removal and re-attachment of the car seat. It’s crucial to verify that the base is correctly installed before securing the car seat.
Refer to the base’s instruction manual for specific installation guidelines and compatibility information. Always prioritize using a compatible base to maximize safety and ease of use.

Using the Primo Viaggio 4-35
Peg Perego’s Primo Viaggio 4-35 requires proper harness and SIP adjustments for optimal safety, alongside understanding how to securely latch and unlatch from the base.
Adjusting the Harness System
Properly adjusting the harness system is crucial for your child’s safety within the Primo Viaggio 4-35. Begin by ensuring the harness straps are at or below your baby’s shoulders when rear-facing, and at or above their shoulders when forward-facing. Loosen the straps by pulling the shoulder height adjusters upwards, then re-tighten to the appropriate level;
To tighten the harness, pull the straps at the shoulder level. Avoid twisting the straps, as this can compromise safety. The harness should be snug enough that you cannot pinch any excess webbing at the shoulder. Always double-check the tightness before each journey. Remember to adjust the harness as your child grows to maintain a secure fit. The chest clip plays a vital role, positioning the straps correctly across your child’s shoulders. Refer to the manual for detailed illustrations and guidance on achieving the correct harness adjustment.
Chest Clip Adjustment
The chest clip on the Primo Viaggio 4-35 is a critical component of the harness system, designed to keep the shoulder straps properly positioned. Always ensure both halves of the chest clip are securely latched together before each use. Position the chest clip at armpit level; this ensures optimal protection in the event of a collision.
Adjusting the chest clip is straightforward. Simply unlatch, reposition to the correct height, and firmly re-latch. Avoid placing the chest clip too high or too low, as this can compromise its effectiveness. Regularly check the chest clip’s position, especially as your child grows. The clip should never be positioned on the neck or too far down the chest. Proper chest clip placement, combined with a snug harness, maximizes your child’s safety during travel. Consult the manual’s diagrams for visual guidance.
SIP (Side Impact Protection) Adjustment
The Primo Viaggio 4-35 features adjustable Side Impact Protection (SIP) designed to provide enhanced safety in side-impact collisions. A key benefit of this car seat is that the SIP adjustment requires no re-threading of the harness – a significant convenience for parents.
To adjust the SIP, locate the adjustment mechanism on the side of the car seat. Extend or retract the SIP panels to ensure they are snug against your child’s head and torso, providing maximum coverage. The SIP should be adjusted as your child grows to maintain optimal protection. Regularly check the SIP’s position to confirm it continues to fit correctly. Properly adjusted SIP helps absorb and deflect impact forces, minimizing the risk of injury. Refer to the manual’s illustrations for detailed guidance on SIP adjustment.
Re-latching and Unlatching from the Base
Securely attaching and detaching the Primo Viaggio 4-35 from its base is crucial for safe travel. To unlatch, locate the release handle on the car seat – typically positioned at the rear. Firmly press or pull the handle as indicated in the manual, simultaneously lifting the car seat slightly. Ensure the seat is completely disengaged before attempting to remove it from the base.
For re-latching, align the car seat with the base, listening for a clear “click” sound confirming a secure connection. Verify the connection by firmly pulling upwards on the car seat; it should not move. The manual details the specific latching points and provides visual aids. Always double-check the connection before each journey. Remember, proper latching is vital for the car seat’s protective function.

Understanding the Nido Component
The Primo Viaggio 4-35 Nido system enhances newborn comfort and safety, offering a semi-reclined position and optimized ergonomics for infants, as certified by standards.
Primo Viaggio 4-35 Nido K Specifics
The Primo Viaggio 4-35 Nido K model is specifically engineered for the earliest stages of infancy, prioritizing a secure and comfortable environment for newborns. This version is certified for use both with and without the dedicated base, though utilizing the base is strongly recommended to simplify the installation process and maximize safety.
A key feature of the Nido K is its ability to be easily unlatched from the base, as detailed on page 27 of the manual, and then securely re-latched. This facilitates convenient transitions between vehicle and stroller systems. It’s crucial to thoroughly read and understand all instructions before initial use.
The Nido K also boasts adjustable Side Impact Protection (SIP) without the need for re-threading, ensuring optimal protection as your child grows. Always consult a certified Child Passenger Safety Technician if you have any doubts regarding proper installation or usage. Remember, proper usage is paramount for your child’s safety.
Benefits of the Nido System
The Nido System, integrated into the Primo Viaggio 4-35, provides a uniquely supportive and ergonomic environment for newborns, mimicking the natural womb position. This design promotes optimal spinal alignment and reduces stress on a baby’s developing body during travel. The system’s contoured shape and plush padding offer superior comfort for extended journeys.
Beyond comfort, the Nido System enhances safety by providing enhanced head and neck support, crucial for infants with limited muscle control. It contributes to a more secure fit within the car seat’s harness system. The Nido component is easily removable as your child grows, adapting to their changing needs.
This innovative feature, combined with the car seat’s overall design, ensures a safe, comfortable, and developmentally appropriate travel experience for your little one, making every ride more peaceful for both baby and parent.

In such instances, consulting a certified Child Passenger Safety Technician (CPST) is highly recommended. A CPST possesses specialized training to ensure your car seat is correctly installed and appropriate for your vehicle and child.

Proper Usage of the Base
The Peg Perego Primo Viaggio 4-35 base is designed to simplify installation and enhance safety. Always ensure the base is installed securely in the vehicle, following the instructions detailed in the manual – either using the LATCH connectors or vehicle seat belts. Verify the base doesn’t move more than one inch side-to-side or front-to-back once installed.
Regularly inspect the base for any signs of damage. The recline indicator must be correctly positioned according to your vehicle’s specifications. Remember, the base is certified for use with the Primo Viaggio 4-35, and utilizing it is highly recommended for easier and safer installation.
