Forward collision alert provides advance warning, and front pedestrian braking adds protective coverage in congested areas. The HD rear vision camera eliminates blind spots during reversing maneuvers.
For those who tow, the integrated trailer brake controller and hitch guidance system simplify hookup and enhance control while pulling a load. Chrome assist steps and a spray-on bedliner protect the truck bed and make loading more convenient. The 3.23 rear axle ratio supports the Trailering Package for added capability.
