Quick answer

Enough dry lubricant spray must be used Then wait 15 minutes and leave the seat in this position! Only then adjust the seat into the sitting position. Note: Both front seats must always be treated!

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
