Use of the recommended fuel is an important part of the proper maintenance of this vehicle. When driving in the U.S. and Canada, to help keep the engine clean and maintain optimum vehicle performance, we recommend using TOP TIER Detergent Gasolines.
See www.toptiergas.com for a list of TOP TIER Detergent Gasolines.

Use regular unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 87 or higher. Do not use gasoline with an octane rating below 87, as it may cause engine damage and will lower fuel economy.
Use of Seasonal Fuels
Use summer and winter fuels in the appropriate season. The fuels industry automatically modifies the fuel for the appropriate season.
If fuel is left in the vehicle tank for long periods of time, driving or starting could be affected. Drive the vehicle until the fuel is at one-half tank or less, then refuel with the current seasonal fuel.
Prohibited Fuels
Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are available in some cities. If these gasolines comply with the previously described specification, then they are acceptable to use.
However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must be used only in FlexFuel vehicles.
Caution
Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts.
That damage would not be covered under the vehicle warranty.
Some gasolines, mainly high octane racing gasolines, can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). Do not use gasolines and/or fuel additives with MMT as they can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp may turn on. If this occurs, see your dealer for service.

In the event that the vehicle requires damage repairs, GM recommends that you
take an active role in its repair. If you have a pre-determined repair facility
of choice, take the vehicle there, or have it towed there.

The passenger sensing system turns off the front outboard passenger frontal airbag
and knee airbag under certain conditions. No other airbag is affected by the passenger
sensing system. See Passenger Sensing System on page 3-25 for important information.

Driving on Snow or Ice
Drive carefully when there is snow or ice between the tires and the road, creating
less traction or grip.
Wet ice can occur at about 0°C (32° F) when freezing rain begins to fall, resulting
in even less traction. Avoid driving on wet ice or in freezing rain until roads
can be treated with sal ...
