The SLT adds power front bucket seats, leather upholstery, tri-zone automatic climate control, Bose audio with a six-CD changer, power-adjustable pedals, remote vehicle start, an auto-dimming rearview mirror (with a built-in rearview camera) and rear park assist.
The top-shelf Denali gains unique styling touches that include lower body cladding and a unique grille, 20-inch alloy wheels, a power liftgate, heated and ventilated front seats, heated second-row seats with a power-folding feature, a larger display for the rearview camera and a navigation system.
Some of the standard features found on the upper trim levels can be added to the lower ones as optional equipment. Other options (depending on trim) include 20- and 22-inch wheels, a sunroof, a navigation system, a side blind-zone alert system, second-row captain's chairs and a rear-seat entertainment system.
