Although GM's interior measurements don't show it, the Canyon feels wider inside than the Sonoma, especially in the rear seat of the crew cab, which more easily accommodates three adults. Front and rear seats are chair height; that allows the driver excellent visibility over the hood and improves leg room and comfort for rear-seat passengers. The front seats are still the first-class section of the cabin, but those in coach won't have to endure the pain of the old sideways-mounted seats in old extended-cab pickups. Our biggest gripe with the Canyon is directed at its seats. The seat bottoms are flat and lack sufficient lateral support, so we always felt like we were sinking to one side or the other.

Even the Canyon's extended cab is large enough to orient its occasional passengers facing forward. Don't expect them to be comfortable, though. The back seat in the extended cab is cramped for anything but short trips to the store for Munchkins. Better to flip the rear seats down, which opens up space for cargo. With modifications (like a fleece mat), it would work passably for a medium-size dog. The front-hinged doors on both sides of the extended cab offer good access to this area.

The instrument panel has large white numerals on a black background, with the orange needles that GM loves. They're easy to read at a glance. Lighting functions are clustered on the dash to the left of the steering wheel; there are no switches in any remote location. Turning on the dome light requires spinning the small wheel used to dim the instrument lights and we found this a bit challenging in the dark. We recommend opting for the electrochromic ($175) mirror, which features a pair of map lights, compass and outside temperature display, and dims automatically.

The center stack, outlined with silver-colored plastic, neatly groups together 4x4, audio, and HVAC functions. The emergency flasher button is high in the center where it's easily seen. The cruise control switches, however, are the same turn-signal-stalk system GM has used since the 1970s, albeit refined. Some people hate it; others are familiar with it and don't seem to mind.

The Canyon features triple seals around the doors, another example of its refinement relative to the old Sonoma. The seals not only reduce water and dust intrusion; they also reduce wind noise for a quieter cab.
