The following are the minimum

requirements for circuits used to charge this vehicle:

. 120 volts/15 amps

. 240 volts/20 amps

Charging equipment with a rating of

at least 240 volts/20 amps will provide the fastest charging time and best

charging efficiency to recharge the

high voltage battery. 240 volt/40 amp circuits provide flexibility for future

vehicle charging needs. Always follow the charging equipment installation

instructions. Contact your dealer for more information.

Caution

Do not use portable or stationary backup generating equipment to

charge the vehicle. This may cause damage to the vehicle's charging

system. Only charge the vehicle from utility supplied power.

Fuel

GM recommends the use of TOP

TIER® detergent gasoline to keep the engine cleaner and reduce engine

deposits. See www.toptiergas.com for a list of TOP TIER detergent gasoline

marketers and applicable countries.

Do not use any fuel labeled E85 or FlexFuel. Do not use gasoline with ethanol levels greater than 15% by volume.

For the 2.0L L4 turbo engine,

premium unleaded gasoline meeting ASTM specification D4814 with a

posted octane rating of 93 is highly

recommended for best performance

and fuel economy. Unleaded gasoline with an octane rated as low as 87 can be used. Using unleaded gasoline

rated below 93 octane, however, will lead to reduced acceleration and fuel economy. If knocking occurs, use a

gasoline rated at 93 octane as soon as possible, otherwise, the engine could

be damaged. If heavy knocking is heard when using gasoline with a 93 octane rating, the engine needs service.

For the 3.6L V6 engine, use regular unleaded gasoline meeting ASTM

specification D4814 with a posted

octane rating of 87 or higher. Do not use gasoline with a posted octane

rating of less than 87, as this may

cause engine knock and will lower fuel economy.

For the 3.0L twin turbo V6 engine, use premium unleaded gasoline meeting

ASTM specification D4814 with a posted octane rating of 93.

If unavailable, unleaded gasoline with a posted octane rating of 91 may be

used, but with reduced performance

and fuel economy. If the octane is less
