Parking on Hills
{CAUTION
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet for vehicles
with an automatic transmission,
or into gear for vehicles with a
manual transmission. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park) for vehicles
with an automatic transmission
or into gear for vehicles with
a manual transmission.
5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake pedal while you:
•start the engine,
•shift into a gear, and
•release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual’s Maintenance Schedule or
Index for more information. Things
that are especially important in trailer
operation are automatic transmission
fluid, engine oil, axle lubricant, belts,
cooling system and brake system.
It is a good idea to inspect these
before and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
on page 9-23.

General Information
For service and parts needs, visit
your dealer/retailer. You will receive
genuine GM parts and GM-trained
and supported service people.
Genuine GM parts have one of
these marks:
California Proposition
65 Warning
Most motor vehicles, including this
one, contain and/or emit chemicals
known to the State of California to
cause cancer and birth defects
or other reproductive harm. Engine
exhaust, many parts and systems
(including some inside the vehicle),
many fluids, and some component
wear by-products contain and/or emit
these chemicals.
9-2 Vehicle Care
When you go to your GM dealer/
retailer and ask for GM Accessories,
you will know that GM-trained and
supported service technicians will
perform the work using genuine GM
Accessories.
Also, seeAdding Equipment to
the Airbag-Equipped Vehicle
on page 2-35.Vehicle Checks
Doing Your Own
Service Work
{CAUTION
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
•Be sure you have sufficient
knowledge, experience, the
proper replacement parts, and
tools before attempting any
vehicle maintenance task.
(Continued)
CAUTION (Continued)
•Be sure to use the proper
nuts, bolts, and other
fasteners. English and
metric fasteners can be
easily confused. If the wrong
fasteners are used, parts
can later break or fall off.
You could be hurt.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order
the proper service manual,
see Service Publications Ordering
Information on page 12-12 .
9-4 Vehicle Care
This vehicle has an airbag system.
Before attempting to do your
own service work, seeAirbag
System Check on page 2-36 .
Keep a record with all parts receipts
and list the mileage and the date
of any service work performed.
See Maintenance Records on
page 10-18.Hood
To open the hood:
1. Pull the release handle, located below the instrument panel to
the left of the steering wheel. 2. From the front of the vehicle,
pull up on the secondary
hood release located near
the middle of the hood.
3. Lift the hood.
4. Release the hood prop rod from its retainer and insert into the slot,
moving it straight up. If it is moved
to the side or toward the inside
of the vehicle, it may become
detached.
Before closing the hood, be sure
all the filler caps are on properly.
Return the hood prop rod carefully
back to its retainer to avoid
damaging the vehicle.

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.
9-12 Vehicle Care
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.
9-14 Vehicle Care
5. Put the cap back on the coolantrecovery tank, but leave the
pressure cap off.
6. Start the engine and let it run until you can feel the upper
radiator hose getting hot. Watch
out for the engine cooling fan.
7. By this time, the coolant level inside the radiator filler neck may
be lower. If the level is lower,
add more of the proper coolant
mixture through the filler neck
until the level reaches the base
of the filler neck.
8. Then replace the pressure cap. At any time during this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure
cap. Be sure the ears on the
pressure cap are in line with
the vent tube.Engine Overheating
A coolant temperature gage is
located on the vehicle’s instrument
panel. See Engine Coolant
Temperature Gage on page 4-11 .
Check to see if the electric engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, the vehicle needs
service.
If no problem is apparent, but the
coolant level is not at or above the
FULL mark, add a 50/50 mixture
of clean, drinkable water and
DEX-COOL
®coolant at the coolant
recovery tank. See Engine Coolant
on page 9-19 for more information
about the proper coolant mixture.
If the coolant inside the coolant
recovery tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on
a level surface.
If Steam Is Coming From Your
Engine
{CAUTION
Steam 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 your
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get
out of the vehicle until the engine
is cool.
Notice: If the engine catches
re because of being driven with
no coolant, your vehicle can be
badly damaged. The costly repairs
would not be covered by the
vehicle warranty.
