Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States
or Canada, the proper fuel might
be hard to find. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused by
use of improper fuel would not be
covered by the vehicle warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now required
to contain additives that help prevent
engine and fuel system deposits
from forming, allowing the emission
control system to work properly.
In most cases, you should not have
to add anything to the fuel. However,
some gasolines contain only the
minimum amount of additive required
to meet U.S. Environmental
Protection Agency regulations.
To help keep fuel injectors and
intake valves clean, or if the vehicle
experiences problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed
by the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found
at www.toptiergas.com.For customers who do not use
TOP TIER Detergent Gasoline
regularly, one bottle of GM Fuel
System Treatment PLUS, added to
the fuel tank at every engine oil
change, can help clean deposits
from fuel injectors and intake valves.
GM Fuel System Treatment
PLUS is the only gasoline additive
recommended by General Motors.
It is available at your dealer/retailer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
8-40 Driving and Operating
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping. When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes
might have to be used so much that
they would get hot and no longer
work well.
Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower gear
if the transmission shifts too often
under heavy loads and/or hilly
conditions. For vehicles with a
manual transmission, it is better
not to use the highest gear.When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at a
lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 9-23.
8-46 Driving and Operating
•GM6094MUse only an oil that meets GM
Standard GM6094M.
•SAE 5W-30SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use
other viscosity oils such
as SAE 20W-50.
•American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst symbol
on the container. This symbol
indicates that the oil has been
certified by the American
Petroleum Institute (API). Notice:
Use only engine oil
identi ed as meeting GM Standard
GM6094M and showing the
American Petroleum Institute
Certi ed For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered
by the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold,
where the temperature falls
below −29°C (−20°F), use either
an SAE 5W-30 synthetic oil or an
SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at
extremely low temperatures. Always
use an oil that meets the required
specification, GM6094M.
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
starburst symbol that meet GM
Standard GM6094M 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.
When to Change Engine Oil
Change the oil and filter every
8 000 km (5,000 miles) or
3 months, whichever occurs first.
See Scheduled Maintenance on
page 10-3.
Vehicle Care 9-11
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, 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.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
Check the fluid in the transmission
and differential at the intervals listed
inScheduled Maintenance on
page 10-3, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 10-15 .
How to Check Automatic
Transmission Fluid
This operation can be difficult, you
may choose to have this done at the
dealer/retailer service department.
If you do it yourself, be sure to
follow all the instructions here,
or you could get a false reading
on the dipstick. Wait at least 30 minutes before
checking the transmission fluid level
if you have been driving:
•When outside temperatures are
above 90°F (32°C).
•At high speed for quite a while.
•In heavy traffic — especially
in hot weather.
•While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is 158°F to
176°F (70°C to 80°C).
Get the vehicle warmed up by
driving about 15 miles (24 km)
when outside temperatures
are above 50°F (10°C). If it is
colder than 50°F (10°C), you
may have to drive longer.

How to Add Automatic
Transmission Fluid
Refer to the Maintenance
Schedule to determine what
kind of transmission fluid to use.
Recommended Fluids and
Lubricants on page 10-15.
If the fluid level is low, add only
enough of the proper fluid to bring
the level into the area between
dimples on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the dipstick
hole to bring it to the proper level.
It does not take much fluid,
generally less than one pint
(0.5 L). Do not overfill. Notice:
Too much or too
little uid can damage your
transmission. Too much can mean
that some of the uid could come
out and fall on hot engine parts or
exhaust system parts, starting a
re. Too little uid could cause the
transmission to overheat. Be sure
to get an accurate reading if you
check your transmission uid.
3. After adding fluid, recheck the fluid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
4. When the correct fluid level is obtained, push the dipstick
back in all the way; then press
the tab down to lock the dipstick
in place.
Manual Transmission
Fluid
When to Check
A good time to have your manual
transmission fluid level checked
is when the engine oil is changed.
However, the fluid in your manual
transmission does not require
changing.
How to Check
This operation can be difficult, you
may choose to have this done
at your dealer/retailer service
department.
If you do it yourself, be sure to
follow all the instructions here, or
you could get a false reading.
