New for 2012

The Canyon sees only some minor changes for 2012. A Bodyguard Package provides bed rail covers and molded splash guards, and an available Chrome Accessory Package includes a chrome exhaust tip and fuel door. For off-road enthusiasts, four-wheel-drive models come with an automatic rear locking differential, which is also standard on crew-cab models.
