DRIVING AND OPERATING
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
than 91, the engine could be damaged
and the repairs would not be covered
