This system provides two lower anchors and a top tether anchor to be used to secure a child seat to the vehicle seat structure. These anchorages are designed to make it easier to properly install compatible child safety seats.

OnStar-equipped GMC Canyons feature OnStar dual-mode (analog-digital) equipment. OnStar's digital equipment also includes enhanced hands-free voice recognition capabilities including more intuitive continuous digit dialing and improved voice recognition accuracy. OnStar is the leading provider of in-vehicle safety, security and information services in the United States and Canada . Using the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Hands-Free Calling that allows drivers to make and receive voice-activated phone calls using an externally mounted antenna for greater reception. New for 2007, OnStar-equipped models offer turn-by-turn navigation.



New 2.9L and 3.7L engines

New for 2007, GMC Canyon offers larger, more powerful inline four- and five-cylinder engines. Standard on all models (except Crew Cab 4WD and ZQ8 sport suspension models) is a 2.9L DOHC four-cylinder engine, rated at 185 horsepower (138 kW) and 190 lb.-ft. of torque (258 Nm)* - increases of 10 horsepower (7.5 kW) and 5 lb.-ft. (7 Nm) more than the previous four-cylinder. A new, 3.7L DOHC five-cylinder is standard on Crew Cab Z71 and ZQ8 models and available on all other Canyon models; it is rated at 242 horsepower (180 kW) and 242 lb.-ft. of torque (328 Nm)* - increases of 22 horsepower (16.4 kW) and 17 lb.-ft. (23.5 Nm) over the previous five-cylinder.

Both new engines are based on GM's modular inline engine design, which also serves as the foundation for the 4.2L inline-six engine of the GMC Envoy. They feature dual overhead camshafts, variable valve timing, electronic throttle control and other features that contribute to high levels of operating efficiency and fuel economy. Balance shafts help ensure smooth operation of the engines, providing a higher level of refinement.

In addition to their larger displacement - delivered through larger, 3.76-inch (95.5 mm) bores - the 2.9L and 3.7L engines feature improved airflow into and out of the combustion chambers, which helps boost power. They also share additional upgrades and changes, compared to the previous GMC Canyon engines:

- Larger, 1.52-inch (38.7 mm) intake valves, vs. previous 1.45-inch (37 mm) intake valves
- Larger, 1.32-inch (33.5 mm) exhaust valves, vs. previous 1.18-inch (30 mm) exhaust valves
- Revised camshaft profile optimizes valve lift and duration in accordance with larger valves
- Cylinder head airflow increased to match capabilities enabled by larger valves and revised camshaft
- New, noise-reducing oiling system uses cylinder wall squirter system enabled by a hole in each connecting rod that delivers a precise oil stream onto the cylinder wall beneath the piston
- New aluminum camshaft cover helps reduce noise
- Tighter-clearance balance shaft bushings promote quieter operation
- New, 2-megabyte powertrain control module houses new diagnostic information storage
- New cartridge-type engine block heater, which fits neatly into a specially machined block orifice; for used with available engine block heater.


Additionally, the 3.7L five-cylinder engine has several features that help it meet new BIN 5 emissions requirements, including a larger, close-coupled catalytic converter and A.I.R. system.
