Reclining Front Seatbacks - Chevrolet 2002 TrailBlazer Owner's Manual

Reclining Front Seatbacks

If your vehicle has a manual recliner, lift the lever
located on the outboard side of the seat and push the
seatback rearward to recline the seatback. To return the
seatback to the normal position, lift the lever without
pushing rearward on the seatback and the seatback
will move forward.
If your vehicle has power seat controls, the vertical
power seat control described earlier allows the seatback
to recline.

But don't have a seatback reclined if your vehicle
is moving.
