Interior

The Sierra showcases two different interior designs. Work Truck and SLE models are more utility-minded, with large controls and door handles that can be operated while wearing gloves. The SLT offers upgraded materials and a different dash design. The Sierra's cab is inviting, spacious and well-organized. Leather seating is available on the SLE and standard on the SLT. The SLT also gets a Bose stereo, a 10-way power-adjustable driver's seat and a heated windshield-washer system.
