A manufacturer or distributor shall not enter into an agreement or understanding with a new motor vehicle dealer that requires the dealer to waive any provisions of this chapter. However, a dealer may, by written contract and for valuable and reasonable separate consideration, waive, limit, or disclaim a manufacturer's obligations or a dealer's rights under RCW 46.96.080, 46.96.090, 46.96.105, 46.96.140, and 46.96.150, if the contract sets forth the specific provisions of this chapter that are waived, limited, or disclaimed. A manufacturer shall not coerce, threaten, intimidate, or require a new motor vehicle dealer, as a condition to granting or renewing a franchise, to enter into such an agreement or understanding.
