IN BRIEF 25
The low tire pressure warning light
alerts to a significant loss in pressure
of one of the vehicle's tires. If the
warning light comes on, stop as soon
as possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
SeeVehicle Load Limits 0181. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the tire
pressures are getting low and the tires
need to be inflated to the proper
pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor
System 0274.Fuel (LTG 2.0L L4 Turbo
Engine)
Premium Recommended Fuel
Use unleaded petrol rated at 95 RON
or higher in your vehicle. Unleaded
petrol with an octane rating as low as
91 RON may be used, but it will
reduce performance and fuel economy.
See Fuel 0226.
Fuel (LCV 2.5L L4 and LGX
3.6L V6 Engines)
Use only unleaded petrol rated at 91
RON or higher in your vehicle. Do not
use petrol with an octane rating lower
as it may result in vehicle damage and
lower fuel economy. See Fuel0226.
Fuel (LF4 3.6L Twin Turbo
V6 Engine)
Premium Required Fuel
Use 95 RON or higher octane
unleaded gasoline in your vehicle. Do

to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
Track Events and
Competitive Driving
Competitive driving may affect the
vehicle warranty. See the warranty
manual before using the vehicle for
competitive driving.
Caution
Low oil levels can damage the
engine. If using the vehicle for
competitive driving, the engine may
use more oil than it would with
normal use. Check the oil level
often during competitive driving.
Engine Oil
2.0L Turbo (LTG) Engine Only: .
Keep the level at or near 1 L (1 qt)
above the upper mark that shows
the proper operating range on the
engine oil dipstick.
. Use a 600 W fan in addition to the
production option V03.
. Gasolines with a Pump Octane ((R
+M)/2) of 99 or greater and
ethanol content below 15%
volume must be used for
competitive driving to protect
against engine damage. Colder
spark plug ratings should also be
used. Consult your dealer.
3.6L Non-Turbo (LGX) Engine Only:
. 3.6L Non-Turbo (LGX) Engine with
Oil Cooler: Confirm the oil level is
at the upper mark that shows the
proper operating range on the
engine oil dipstick.
3.6L Twin Turbo (LF4) Engine Only:
. The twin turbo 3.6L engine (LF4)
requires premium fuel, and comes
standard with a 7 qt sump,
integrated oil cooler, and other
powertrain and powertrain cooling
components in preparation for
track use. Brake Fluid
.
Before racing, replace existing
brake fluid with a qualified racing
brake fluid from a sealed
container. Brake fluid with a dry
boiling point >279 °C (534 °F) is
qualified. If racing brake fluid is
used, replace it with GM approved
brake fluid before driving on
public roads. See Recommended
Fluids and Lubricants 0314.
. Do not use silicone-based fluids.
If racing brake fluid is in the vehicle
and the age of the brake fluid is over a
month old or unknown, replace the
brake fluid between racing/closed
track driving.
Caution
Failure to change the brake fluid
and transfer case fluid after any
performance or race track driving
could result in damage not covered
by the vehicle warranty. Have the
brake fluid and transfer case fluid
changed by your dealer after any (Continued)

226 DRIVING AND OPERATING
Fuel
Use the recommended fuel for proper
vehicle maintenance.
For the 2.0L L4 turbo engine (LTG),
use unleaded petrol with a posted
octane rating of 95 RON or higher.
Unleaded petrol rated at 91 RON can
be used, but acceleration and fuel
economy will be reduced, and an
audible knocking noise may be heard.
If this occurs, use petrol rated at 95
RON as soon as possible, otherwise
the engine could be damaged. If heavy
knocking is heard when using
unleaded petrol rated at 95 RON, the
engine needs service.
For the 2.5L L4 engine (LCV) and the
3.6L V6 engine (LGX), use unleaded
petrol with a posted octane rating of
91 RON or higher, otherwise an
audible knocking noise may be heard.
If heavy knocking is heard when using
gasoline rated at 91 RON or higher,
the engine needs service.
For the 3.6L V6 twin turbo engine
(LF4), use unleaded petrol with a
posted octane rating of 95 RON or
higher. If the octane is less than 95RON, the engine could be damaged
and repairs would not be covered by
the vehicle warranty. If heavy
knocking is heard when using petrol
rated at 95 RON octane, the engine
needs service.
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
. 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.
(Continued)
Caution (Continued)
.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.
Fuel Additives
Gasoline should contain detergent
additives that help prevent engine and
fuel system deposits from forming.
Clean fuel injectors and intake valves
will allow the emission control system
to work properly. Some gasoline does
not contain sufficient quantities of
additives to keep fuel injectors and
intake valves clean. To make up for
this lack of detergency, consult your
dealer for the GM approved additive
treatment. Add this additive to the
fuel tank at every engine oil change or
every 15 000 km (9,000 mi), whichever
occurs first.
