Child Safety Seats

Guidelines for Seating Children

Your Model S seat belts are designed for adults and larger children. You must restrain infants and small children in the rear seats only, and you must use a suitable child safety seat appropriate for the child’s age, weight, and size.

Never use child safety seats in the front row passenger seat.

Choosing a Child Safety Seat

All children age 12 and under should ride in the second row seats. Always use a child safety seat suitable for a young child’s age and weight. The following table is based on child safety seat recommendations determined by National Highway Traffic Safety Administration (NHTSA). For more information, go to www.nhtsa.gov/ChildSafety/Guidance.

Category Infants Toddlers Young children
Age Birth to 1 year* Over 1 year* 4 years and older, and less than 57 in. (145 cm) tall
Weight Up to at least 20 lbs (9 kg)* Over 20 lbs (9 kg) (minimum) and up to 40 lbs (18 kg)* Over 40 lbs (18 kg)
Type of child safety seat Rear facing (or convertible) Forward facing (or convertible)* Forward facing or seat belt retained booster seat****
Seat position Rear facing only* Rear facing as long as possible, then forward facing* Forward facing
Recommended attachment method If combined weight of child and safety seat is up to 65 lbs (29 kg), attach using either ISOFIX** (lower anchor only) or the seat belt only.*** If combined weight of child and safety seat is over 65 lbs (29 kg), attach using the seat belt only.*** If combined weight of child and safety seat is up to 65 lbs (29 kg), attach using either ISOFIX** (both lower anchors and top tether anchor), or the seat belt and upper tether strap.*** If combined weight of child and safety seat is over 65 lbs (29 kg), attach using the seat belt and upper tether strap.*** Secure the booster seat using lower LATCH anchors (if available) and then restrain the child with the seat belt. If the booster seat is not equipped with LATCH anchors, then secure the booster seat with the child using the seat belt. However, if the combined weight of the child and booster seat exceeds 65 lbs (29 kg), secure the booster seat with the child using the seat belt only.

* Many child safety seats currently available allow children to ride rear-facing using the child safety seat’s integrated 5-point harness for a longer period of time BASED UPON SPECIFIC HEIGHT AND WEIGHT LIMITS. Keep your child in a rear facing seat for as long as possible. CHECK THE CHILD SAFETY SEAT MANUFACTURER’S INSTRUCTIONS AND CAREFULLY FOLLOW ALL INSTRUCTIONS.

** ISOFIX is the international standard for attachment points for child safety seats in passenger cars that enable compliant child safety seats to be quickly and safely secured. The system has other regional names including LATCH ("Lower Anchors and Tethers for Children") in the United States and LUAS ("Lower Universal Anchorage System") or Canfix in Canada. It has also been called the "Universal Child Safety Seat System" or UCSSS.

*** Subject to instructions provided by the child safety seat manufacturer.

****Keep your child in a forward facing child safety seat with a harness and tether until the child reaches the child safety seat's maximum allowable height or weight as specified by the manufacturer of the child safety seat.

Warning
Laws that govern how and where children should be carried when traveling in a vehicle are subject to change. It is the driver’s responsibility to keep up to date on, and comply with, all current regulations in the region(s) where Model S is driven.

Seating Larger Children

If a child is too large to fit into a child safety seat, but too small to safely fit into the standard seat belts, use a booster seat appropriate for the child’s age and size. Carefully follow the manufacturer’s instructions to secure the booster seat.

Installing Child Safety Seats

There are two general methods used to install child safety seats:

  • Seat belt retained - these seats are secured using the vehicle’s seat belts.
  • ISOFIX retained - these seats attach to anchor bars built into the vehicle’s rear seats.

Check the child safety seat manufacturer’s instructions and the table in this manual to determine which installation method to use. Some child safety seats can be installed using either method. Always follow the child safety seat manufacturer’s instructions.

Installing Seat Belt Retained Child Seats

First, make sure that the child safety seat is appropriate for the weight, height, and age of the child.

Avoid dressing the child in bulky clothing and do not place any objects between the child and the restraint system.

Adjust harnesses for every child, every trip.

To securely hold child safety seats, all passenger seating positions are equipped with an automatic locking retractor (ALR) that, by pulling the seat belt beyond the length needed for a typical adult occupant, locks the belt into place until the seat belt is unbuckled and the webbing is fully retracted. The ALR mechanism operates as a ratchet, winding in slack and preventing the seat belt from extending any further until it has been completely rewound. When installing a child safety seat, engage the belt's automatic locking retractor by pulling the seat belt webbing until it is fully extended. The ALR system engages only when the seat belt is at its maximum extension point.

Informational PurposesAn informational icon, calling your attention
Note
An automatic locking retractor disengages only when the seat belt is unbuckled and fully retracted. The belt can then be worn as a normal belt, sliding freely in and out and locking tight only in an emergency. Once disengaged, the belt must be fully extended to re-engage the locking mechanism whenever you install a child safety seat.

Always follow the detailed instructions provided by the child safety seat manufacturer. General guidelines are provided below.

  1. Place the child safety seat in Model S, and fully extend the seat belt. Route and buckle the seat belt in accordance with the child safety seat manufacturer’s instructions.

  2. Allow the seat belt to retract, and remove all slack in the seat belt while firmly pushing the child safety seat into the Model S seat.
  3. Once all slack has been removed, forcefully pull the seat belt webbing to confirm that the automatic locking retractor (ALR) is engaged.
    Informational PurposesAn informational icon, calling your attention
    Note
    The ALR disengages only after unbuckling and fully retracting the seat belt webbing. Once disengaged, the belt must be fully extended to re-engage the locking mechanism.
  4. Attach the upper tether strap(s), as required by the manufacturer of the child restraint system (see Attaching Upper Tether Straps).

Installing ISOFIX (LATCH) Child Seats

Lower ISOFIX anchors are provided in the second row outboard seats. The anchors are located between the seat's back rest and rear cushion. The exact location of each anchor is identified by a child safety seat identification button, illustrated below. The button is located on the seat back, directly above its associated anchor.

In the rear seats, install ISOFIX child safety seats in the outboard seating positions only. Use only a seat belt retained seat in the center position.

To install a ISOFIX child safety seat, carefully read and follow the instructions provided by the manufacturer of the child restraint system. These instructions describe how to slide the child restraint system onto the seat's anchor bars until you hear it "click" into place. You may need to push the child restraint system firmly against the seat back to ensure it fits snugly.

Before seating a child, ensure that the child restraint system is securely installed. Grasp the front of the child restraint system with one hand on each side, and attempt to:

  • Twist the child restraint system from side to side.
  • Pull the child restraint system away from the seat.

If the child restraint system moves away from the seat, both latches are not fully engaged onto the seat's anchor bars. You must reinstall it and try again. It is critical that both latches on the child restraint system are fully engaged.

Do not use ISOFIX anchors with child seats or booster seats that have an integrated safety belt where the combined weight of the child plus the child restraint system exceeds 29.5 kg.

Attaching Upper Tether Straps

If an upper tether strap is provided, attach its hook to the anchor point located on the back of the rear seats.

Testing a Child Safety Seat

Before seating a child, always make sure the child safety seat is not loose:

  1. Hold the child safety seat by the belt path and try to slide the safety seat from side to side and front to back.
  2. If the seat moves more than 2.5 cm, it is too loose. Tighten the belt or reconnect the ISOFIX retained child safety seat.
  3. If you are unable to reduce slack, try a different seat location or try another child safety seat.
