5-12 Instruments and Controls OBD II system has detected a
problem and diagnosis and service
might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the service technician in
correctly diagnosing any
malfunction.
{ CautionIf the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty. { CautionModifications made to the engine,
transmission, exhaust, intake,
or fuel system of the vehicle or
the replacement of the original
tires with other than those of the
same size and type as the
originals can affect the vehicle's
emission controls and can cause
this light to come on.
Modifications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 10-3 .

8-4 Climate Controls Operation Tips .
Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into the
vehicle. .
Use of non-GM approved hood
deflectors may adversely affect
the performance of the system. .
Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively. Maintenance Service This vehicle may have the new
environmentally friendly refrigerant,
R1234yf. This refrigerant has a
significantly reduced global warming
impact on the environment,
compared to the traditional
automotive refrigerant, R-134a. All
vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system should only
be serviced by trained and certified
technicians. The air conditioning
evaporator should never be repaired
or replaced by one from a salvage
vehicle. It should only be replaced
by a new evaporator to ensure
proper and safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.

9-22 Driving and Operating Each time the engine is started,
or when the shift lever is shifted to
any position other than D (Drive),
the Overdrive off mode will be
automatically turned off.
Accelerator Downshift in D
Position For passing or hill climbing, depress
the accelerator pedal to the floor.
This shifts the transmission down
into a lower gear, depending on the
vehicle speed.
Fail Safe
When the fail-safe operation occurs,
the CVT will not be shifted into the
selected driving position.
If the vehicle is driven under
extreme conditions, such as
excessive wheel spinning and
subsequent hard braking, the
fail-safe system may be activated.
The MIL may come on to indicate
the fail-safe mode is activated. See
Malfunction Indicator Lamp on
page 5-11 . This will occur even if all
electrical circuits are functioning properly. In this case, place the
ignition switch in the OFF position
and wait for 10 seconds. Then place
the ignition switch back in the ON
position. The vehicle should return
to its normal operating condition. If it
does not return to its normal
operating condition, have a dealer
check the transmission and repair if
necessary.
{ WarningWhen the high fluid temperature
protection mode or fail-safe
operation occurs, vehicle speed
may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase
the chance of a collision. Be
especially careful when driving.
If necessary, pull to the side of
the road at a safe place and allow
the transmission to return to
normal operation, or have it
repaired if necessary. Brakes Antilock Brake
System (ABS)
{ Warning .
The ABS is a sophisticated
device, but it cannot prevent
accidents resulting from
careless or dangerous driving
techniques. It can help
maintain vehicle control
during braking on slippery
surfaces. Remember that
stopping distances on
slippery surfaces will be
longer than on normal
surfaces even with ABS.
Stopping distances may also
be longer on rough, gravel or
snow covered roads, or if you
are using tire chains. Always
maintain a safe distance from

9-38 Driving and Operating 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 will reduce spark plug
life and affect emission control
system. The malfunction indicator
lamp may turn on. If this occurs, see
your dealer for service.
California Fuel
Requirements If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle may not pass a smog-check test. See Malfunction Indicator
Lamp on page 5-11 . If this occurs,
return to your authorized dealer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs may not be
covered by the vehicle warranty.
Fuels in Foreign
Countries If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, manganese, or any other
fuel not recommended. Costly
repairs caused by use of improper
fuel would not be covered by the
vehicle warranty. Fuel Additives To keep fuel systems clean, TOP
TIER Detergent Gasoline is
recommended. See Fuel on
page 9-37 .
If TOP TIER Detergent Gasoline is
not available, one bottle of Fuel
System Treatment PLUS added to
the fuel tank at every engine oil
change can help. Fuel System
Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Do not use additives with E85 or
FlexFuel.

Vehicle Care 10-17If Steam is Coming from the
Engine Compartment
{ WarningSteam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool. Overheated Engine
Protection
Operating Mode The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level: .
The engine coolant temperature
warning light will illuminate. .
Engine power may be reduced. .
The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed. The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:
1. The engine coolant temperature
is not reduced.
2. The air conditioning cooling
function does not turn back ON.
3. The engine oil pressure low/
engine coolant temperature high
warning light illuminates, this
may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine
to cool. If after checking the oil
