The 2010 Terrain is an all-new entry in the compact crossover segment for GMC. It's functional and frugal, with rugged styling to go along with exceptional fuel economy.(Fig. 1)
Since the Terrain is an all-new vehicle for GMC, customers may find the operation of some Terrain features different from their experience with past GMC models. Before attempting a repair for a customer concern, be sure the customer understands the proper operation of the feature in question.
Like the new Equinox, the Terrain is based on a new front-drive crossover architecture. For more details on many Terrain features, refer to the Equinox article in the June 2009 TechLink.
Powertrains
There are two powertrain combinations available on the Terrain.
2.4L 4-Cylinder Engine (RPO LAF) with 6T45 6-Speed Automatic Transmission
The 2.4L SIDI VVT 4-cylinder engine provides 182 horsepower and 174 lb.-ft. of torque and is mated to the Hydra-Matic 6T45 6-speed automatic transmission. Both front- and all-wheel-drive configurations are available. Fuel economy is 21 mpg city and 30 mpg highway (10.1 L/100 km city and 6.7 L/100 km highway).
On vehicles with the 4-cylinder engine, the Economy (ECO) Mode can improve the vehicle's fuel economy by changing the transmission shift points and making several other fuel-saving adjustments. Press the ECO button by the shift lever to turn this feature on or off. The ECO light in the instrument cluster illuminates.
4-cylinder models also feature the Active Noise Cancellation (ANC) system, which detects certain sounds inside the vehicle and sends counteracting sound waves through the audio system's speakers to help increase quietness with little added mass, aiding fuel economy.
TIP: For optimal ANC performance, do not block the cargo area speaker.
3.0L V6 Engine (RPO LF1) with 6T70 6-Speed Automatic Transmission
The 3.0L SIDI VVT V6 engine produces 264 horsepower and 214 lb.-ft. of torque, is available in both front- and all-wheel-drive configurations and has a 3500-lb. towing capacity. It provides 18 mpg city and 25 mpg highway (11.9 L/100 km city and 8.1 L/100 km highway).
The Hydra-Matic 6T70 6-speed transmission is designed for torque handling capability to meet the needs of the high-output 3.0L V6.
GM Global-A Architecture
The new Terrain uses the GM Global-A Serial Data Electrical Architecture -- a high-and low-speed data network that connects system modules around the vehicle and ensures that information is properly communicated and shared among them.
TIP: You will use the MDI with GDS software and a laptop PC in place of the Tech 2 for diagnosis.
Infotainment
The USB connection in the center console can be used to play a portable audio device and download files to the audio system hard drive.
TIP: The USB jack provides true iPod® capability, enabling recharging and control of the iPod using the audio system controls. However, not all iPod devices are compatible, in which case it's necessary to use the AUX jack.
Power Liftgate
The available programmable power liftgate has three modes of operation. Mode selection is controlled by the interior mode switch located on the overhead console. (Fig. 2)
In the 3/4 Mode (programmable mode), the liftgate powers open to a height programmed by the owner (to prevent the liftgate from hitting overhead obstructions, such as a garage door).
Power Door Locks
The power door lock buttons are located on the center console below the audio controls. (Fig. 3)

A locked door can be unlocked by pulling the inside handle TWICE -- first to unlock, second to release the door latch.
Rear Vision Camera
The standard rear vision camera displays images either in the rearview mirror (using a built-in mini display screen) or the navigation system screen (if equipped). The camera is located above the license plate.
Service Updates
The latest service updates that apply to the new Terrain include:
Difficulty with Tire Pressure Monitor Sensor Learn Process - Updated procedure available for performing a tire pressure monitor system relearn after a tire rotation or replacing a sensor.
Do Not Swap Modules in Vehicles with Global Electrical Systems - Swapping ECMs or other modules will result in a no start condition.
Introduction of New Global Diagnostic System (GDS) - Requires the use of the MDI with GDS software and a laptop PC in place of the Tech 2 for diagnosis. Refer to bulletin #09-00-89-019.
