Cybex Sirona Gi i-Size in a rental car

Installing the toddler seat with its ISOFIX base.

Fitting it in your car.

About ten minutes. The Cybex manual in your bag has every detail and is always the final word.

Cybex Sirona Gi i-Size in Almond Beige
Cybex Sirona Gi i-SizeRotating seat on an ISOFIX base with a load leg. Rear-facing, or forward-facing from 15 months.
  1. Click in the ISOFIX arms

    Pull out both ISOFIX arms and push them onto the car’s ISOFIX anchors until they click and the indicators show green.

  2. Push the base back

    Push the seat firmly towards the car’s backrest so the base sits flat and tight.

  3. Set the load leg

    Fold out the load leg and extend it until it stands firmly on the floor and its indicator shows green.

  4. Turn it to the door

    Turn the seat towards the open door, put your child in, set the headrest so the harness comes out at shoulder height, and buckle up.

  5. Tighten and lock the direction

    Pull the harness snug, then turn the seat until it clicks: rear-facing, or forward-facing once your child is at least 15 months old.

Keep it rear-facing for as long as your child fits. Never rear-facing in front of an active airbag.

Before you drive.

Thirty seconds of checks, every time you buckle up.

  • Every indicator on the seat shows green.
  • At the base, the seat moves no more than about 2.5 cm side to side.
  • The harness is snug: you can’t pinch a fold of strap at the shoulder.
  • Coats off before buckling. Put the jacket over the harness instead.
  • Never a rear-facing seat in front of an active airbag.
  • Booster: lap belt low over the hips, shoulder belt across the middle of the shoulder.
