Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
inated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving. If
you become tired or sleepy, nd
a safe place to park your vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
4-30 Driving Your Vehicle

The malfunction indicator lamp
could turn on and the vehicle
might fail a smog-check test.
SeeMalfunction Indicator Lamp
on page 3-30. If this occurs, return
to your authorized dealer/retailer
for diagnosis. If it is determined
that the condition is caused by the
type of fuel used, repairs might
not be covered by the vehicle
warranty.
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, orif the vehicle experiences problems
due to dirty injectors or valves,
look for gasoline that is advertised
as TOP TIER Detergent Gasoline.
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.
Also, your dealer/retailer has
additives that will help correct and
prevent most deposit-related
problems.
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 specications 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.
Notice:This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under
the vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the
attendant where you buy gasoline
whether the fuel contains MMT.
We recommend against the use of
such gasolines. Fuels containing
MMT can reduce the life of
spark plugs and the performance

of the emission control system could
be affected. The malfunction
indicator lamp might turn on. If this
occurs, return to your dealer/retailer
for service.
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 nd. 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.
Filling the Tank
{CAUTION
Fuel vapor burns violently and a
fuel re can cause bad injuries.
To help avoid injuries to you and
others, read and follow all the
instructions on the pump island.
Turn off the engine when you are
refueling. Do not smoke if you are
near fuel or refueling the vehicle.
Do not use cellular phones. Keep
sparks, ames, and smoking
materials away from fuel. Do not
leave the fuel pump unattended
when refueling the vehicle. This is
against the law in some places.
Do not re-enter the vehicle while
pumping fuel. Keep children away
from the fuel pump; never let
children pump fuel.The fuel cap is located on the driver
side of the vehicle.
To remove the fuel cap, turn it
slowly counterclockwise. While
refueling, let the fuel cap hang by
the tether, if it has one.

When to Add Engine Oil
If the oil is below the cross-hatched
area (L), add at least one quart/liter
of the recommended oil. This
section explains what kind of oil to
use. For engine oil crankcase
capacity, seeCapacities and
Specifications on page 5-96.
Notice:Do not add too much oil.
If 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 be damaged.SeeEngine Compartment Overview
on page 5-10for the location of
the engine oil ll cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the
way back in when you are through.
What Kind of Engine Oil to Use
Look for three things:
5-14 Service and Appearance Care

GM6094M
Use only an oil that meets
GM Standard GM6094M.
SAE 5W-30
SAE 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
certied by the American
Petroleum Institute (API).Notice:Use only engine oil
identied as meeting GM
Standard GM6094M and showing
the American Petroleum
Institute Certied 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−20°F
(−29°C), 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
specication, GM6094M. See “What
Kind of Engine Oil to Use” for
more information.
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 ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and lter. This is based on
engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions,
the mileage at which an oil change
is indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.

Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission uid level is when
the engine oil is changed.
Change the uid and lter at the
intervals listed inAdditional
Required Services on page 6-6, and
be sure to use the transmission
uid listed inRecommended Fluids
and Lubricants on page 6-12.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, you may choose
to have this done at the
dealer/retailer service department.
If adding it yourself, be sure to follow
all the instructions here, or there
could be a false reading on the
dipstick.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.
Wait at least 30 minutes before
checking the transmission uid 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 uid
should be at normal operating
temperature, which is 180°F to
200°F (82°C to 93°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), drive the vehicle
in 3 (Third) until the engine
temperature gage moves and then
remains steady for 10 minutes.
A cold uid check can be made after
the vehicle has been sitting for
eight hours or more with the engine
off, but this is used only as a
reference. Let the engine run at
idle for ve minutes if outside
temperatures are 50°F (10°C) or
more. If it is colder than 50°F (10°C),
the engine might have to idle
longer. Should the uid level
be low during this cold check,
check the uid hot before adding
uid. Checking the uid hot gives
a more accurate reading of the
uid level.
5-18 Service and Appearance Care

It does not take much uid,
generally less than one pint (0.5 L).
Do not overll.
Notice:Use of the incorrect
automatic transmission uid may
damage the vehicle, and the
damages may not be covered
by the vehicle’s warranty. Always
use the automatic transmission
uid listed inRecommended
Fluids and Lubricants on
page 6-12.
After adding uid, recheck the
uid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
When the correct uid level is
obtained, push the dipstick
back in all the way; then ip
the handle down to lock
the dipstick in place.
Manual Transmission
Fluid
When to Check
A good time to check the manual
transmission uid is when the
engine oil is changed. However,
the uid in the manual transmission
does not require changing.
How to Check
Because this operation can be a
little difficult, you may choose
to have this done at your GM
dealer/retailer service department.
If doing it yourself, be sure to follow
all the instructions here, or there
could be a false reading.Notice:Too much or too little
uid can damage your
transmission. Too little uid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission uid.
To check the uid:
1. Park the vehicle on a level
surface, then shut the engine off.
Let the vehicle sit until the
transmission case is cool enough
to touch.
2. Remove the ller plug.
