Top Strap Anchor Location
Tahoe/Suburban/Yukon/Yukon XL models without
rear seats: Top strap anchor loops are located at
the bottom rear of the front seat cushion for the right
front passenger's position.
Suburban/Yukon XL Models without Rear Seats
Anchor the top strap to this bracket. Once you have the
top strap anchored, you'll be ready to secure the
child restraint itself.
Tahoe/Suburban/Yukon/Yukon XL models with rear
seats: A child restraint with a top strap should only
be used in the second or third row. Don't use a
child restraint with a top strap in the front seat because
there's no place to anchor the top strap.
An anchor loop bracket for a top strap is located at the
bottom rear of the seat cushion for each seating
position in the second row, and for the center seating
position in the third row.
