"THERE IS NO COOLING OFF PERIOD
California law does not provide for a "cooling off" or other cancellation period for vehicle leases. Therefore, you cannot later cancel this lease simply because you change your mind, decided the vehicle costs too much, or wish you had acquired a different vehicle. You may cancel this lease only with the agreement of the lessor or for legal cause, such as fraud."
"GAP LIABILITY NOTICE
In the event of theft or damage to the vehicle that results in a total loss, there may be a GAP between the amount due upon early termination and the proceeds of your insurance settlement and deductible. THIS LEASE PROVIDES THAT YOU ARE LIABLE FOR THE GAP AMOUNT. Optional coverage for the GAP amount may be offered for an additional price."
