Wire:

Stripped Wire Cross Sectional Area

1.25 mm2 (0.0019 in.2) or more

CAUTION:

If the wire is too thin or an alternative object is used to tie down the curtain shield airbag assembly, it may snap when the airbag is deployed. Always use a wire for Toyota Prius vehicle use with a cross sectional area of at least 1.25 mm2 (0.0019 in.2).

HINT:

To calculate the cross sectional area of the stripped wire:

Cross sectional area = 3.14 x (Diameter)2 / 4

(1) Position the curtain shield airbag assembly inside the tire as shown in the illustration. Minimum Tire Size: Width 185 mm (7.28 in.) Inner Diameter 360 mm (1.18 ft.) CAUTION: Make sure that the wires are tight. If there is slack in the wires, the curtain shield airbag assembly may break loose when the airbag is deployed. NOTICE: The tire may be damaged by the airbag deployment, so use an unneeded tire.
