Driving and Operating 33
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.
Use premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 93.
If unavailable, unleaded gasolinewith 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 by the
vehicle warranty. If heavy knocking
is heard when using gasoline rated
at 93 octane, the engine needs
service.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
. For vehicles which are not
FlexFuel, fuel labeled
greater than 15% ethanol by
volume, such as mid-level
ethanol blends (16 –50%
ethanol), E85, or FlexFuel.
. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can

corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control
system and spark plugs.
. Fuel with a posted octane
rating of less than the
recommended fuel. Using
this fuel will lower fuel
economy and performance,
and may decrease the life of
the emissions catalyst.

Caution (Continued)
(20 °F). Always store high
performance summer tires
indoors and at temperatures
above−7 °C (20 °F) when not in
use. If the tires have been
subjected to −7 °C (20 °F) or less,
let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always
inspect tires before use. See “Tire
Inspection” in the owner ’s
manual.
Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
This could cause a crash, and
you or others could be killed.
Some high-speed rated tires
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle
to be driven at high speeds, make
sure the tires are rated for
high-speed operation, are in
excellent condition, and are set to
the correct cold tire inflation
pressure for the vehicle load. ZL1 and SS with the 1LE package
are equipped with 285/30ZR20
(95Y) and 305/30ZR20 (99Y) or
305/30ZR19 (98Y) and 325/30ZR19
(101Y) size tires that are capable of
high-speed use. Make sure vehicles
with this size tires are inflated to
300 kPa (44 psi) before operating
the vehicle at sustained high-speed
operation at speeds over 160 km/h
(100 mph).
LS/LT with the 1LE package is
equipped with 245/40ZR20 95Y and
275/35ZR20 98Y size tires that are
capable of high-speed use. Make
sure vehicles with this size tires are
inflated to 280 kPa (41 psi) before
operating the vehicle at sustained
high-speed operation at speeds
over 160 km/h (100 mph).
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See
“Vehicle Load
Limits” and“Tire Pressure” in the
owner ’s manual.
