Jordan James, of Crusaders, tackles Leeds' Jamie Jones-Buchanan
Leeds scored 28 unanswered second-half points to get their Super League defence off to a winning start in snowy conditions at plucky Crusaders.
The Welsh side held the Rhinos at 6-6 midway through the second period after Gareth Raynor's try had cancelled out Scott Donald's effort for Leeds.
But Leeds got their noses in front with a breakaway Danny McGuire score.
And Ali Lauitiiti (two), Kevin Sinfield and Brett Delaney all went over late on as the champions eased to victory.
It was tough on Brian Noble's hastily-assembled Crusaders who went toe-to-toe with Leeds for much of the contest.
And the Welsh side's display would have certainly encouraged the 10,334-strong crowd at the Racecourse Ground, who even saw them take an early lead through Michael Witt's penalty after the Rhinos had been penalised for offside.
Normal service appeared to have been resumed when Nick Youngquest, one of eight debutants for Crusaders, allowed a Delaney kick to slip through his legs to present Donald with the simplest of scores.
