Okay, a cut and paste of the text is below. I don't know how to get the images from the PDF document for you. However, I can describe the locations. One of the anchors is above the rear cargo door. The other 2 are on the back of the passenger seats.
My truck does have lower anchors under the rear seats. I know they are there because this is where I attached the seat belt harnesses that my dogs wear. However, I do not think that is their intended purpose.
If it will help you, I can take pics of any areas you need tomorrow. Just let me know what locations you would like to see.
I hope that helps you a bit.
TETHER STRAP ANCHORAGES
Provision is made for the fitting of up to three
child seats or restraint systems in the rear
(second row) seats, of the type that require
tether strap anchorage points.
There are three tether strap anchorage points.
These should be used to attach tether straps
from child seats or restraint systems. Two
anchorage points are fitted to the back of the
second row seat, these should be used for the
two outer seating positions. A third single
anchorage point is located in the centre of the
rear header rail (above the tail door) for
attaching a tether strap from the centre seat
position. The anchorage points are shown in
the accompanying illustrations.
Attaching tether straps
1. Install the child restraint securely in one of
the second row seating positions.
2. Pass the tether strap over the back of the
vehicle seat and beneath the underside of
the head restraint.
3. Attach the clip on the head of the tether
strap to the tether anchor on the back of
the vehicle seat (or, for the centre seating
position, on the header rail above the
taildoor).
4. Tighten the tether strap according to the
manufacturer’s instructions to remove any
slack in the webbing.
WARNING
•Always follow the child seat or restraint
system manufacturer’s instructions when
fitting tether straps.
•When fitting a child seat or restraint
system, always pass the tether strap over
the top of the seat back and beneath the
underside of the head restraint.
•If a child seat or restraint system is to be
fitted to the centre seating position, the
centre armrest must be in the stowed
position (folded into the seat).
