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 functioningproperly. 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.
{Warning
When 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-checktest. 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.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See
Maintenance Schedule on
page 11-3.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10-7 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.

2. Pull out the dipstick and wipe itwith a clean paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the tip
down, and check the level.
When to Add Engine Oil
It should be between the H (High)
and L (Low) marks. This is the
normal operating oil level range.
If the oil level is below the L (Low)
mark, remove the oil filler cap and
pour recommended oil through the
opening. See Engine Compartment
Overview on page 10-7 for the
location of the engine oil fill cap. Add some of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil”
in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12-2. Add enough oil to put
the level somewhere in the proper
operating range. Do not overfill.
Push the dipstick all the way back in
when through.
{Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
(Continued)
Caution (Continued)
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
SeeRecommended Fluids and
Lubricants on page 11-11.
Specification
Ask for and use engine oils that
meet the dexos1™ specification.
Engine oils that have been
approved by GM as meeting the
dexos1 specification are marked
with the dexos1 approved logo. See
www.gmdexos.com.

10-10 Vehicle Care
{Caution
Failure to use the recommended
engine oil can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification.
Use of Substitute Engine Oils if
dexos1 is unavailable: In the event
that dexos1-approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil that
meets American Petroleum Institute
(API) approved specifications of the
appropriate viscosity grade. These
oils have the API certification mark
on the front of the container.
Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the
dexos1 specification are all that is
needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
