2000 CHEVROLET ASTRO instrument panel

3-7
Your vehicle has air vents near the center and on the
sides of the instrument panel that allow you to adjust the
direction and the amount of airflow inside the vehicle.
Move the dial on the vent up or down to direct airflow
to your preference. Increase or reduce the amount of
airflow by opening and closing the louvers. The vents
rotate to direct the airflow from side to side.
When you close a vent, it will increase the flow of air
coming out of any vents that are open.If you have rear heating or rear air conditioning, you
will have adjustable vents in the rear of the vehicle to
help direct the airflow. The rear air conditioning vents
are located in the headliner at the rear of the vehicle.
The rear heating vents are located next to the second and
third seat on the driver's side of the vehicle, near the
floor. You can move the vents to direct the flow of air, or
close the vents altogether. When you close a vent, it will
increase the flow of air coming out of any vents that
are open.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, turn the
blower fan to HIGH for a few moments before
driving off. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging the
inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

4-32 If You Do Decide To Pull A Trailer
If you do, here are some important points:

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you'll be driving. A good source for this
information can be state or provincial police.

Consider using a sway control if your trailer will
weigh 2,000 lbs. (900 kg) or less. You should always
use a sway control if your trailer will weigh more
than 2,000 lbs. (900 kg). You can ask a hitch dealer
about sway controls.

Don't tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.

Then, during the first 500 miles (800 km) that you
tow a trailer, don't drive over 50 mph (80 km/h) and
don't make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.

You should use THIRD (3) (or, as you need to, a
lower gear) when towing a trailer. Operating your
vehicle in THIRD (3) when towing a trailer will
minimize heat buildup and extend the life of your
transmission. See ªTow/Haul Modeº in the Index.Three important considerations have to do with weight:

the weight of the trailer,

the weight of the trailer tongue

and the weight on your vehicle's tires.
Tow/Haul Mode
The Tow/Haul Mode is a feature that assists when
pulling a heavy trailer. The purpose of the Tow/Haul
Mode is:

Reduce the frequency of shifts when pulling a
heavy trailer.

Provide the same shift feel when pulling a heavy
trailer as when the vehicle is unloaded.

Reduce the need to change throttle position when
pulling a heavy trailer.
This feature is turned on or off by pressing a button on
the floor console. When the feature is on, a light on the
instrument panel will illuminate to indicate that the
Tow/Haul Mode has been selected.
See ªTow/Haul Mode Lightº in the Index. The
Tow/Haul Mode is automatically turned off each time
the vehicle is started.

4-38 Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns
than normal. Do this so your 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
When you tow a trailer, your vehicle has to have extra
wiring (included in the optional trailering package).
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you're about to turn, change lanes or stop.When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It's 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 you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
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 you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your 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 PARK (P) for a few
minutes before turning the engine off. If you do get the
overheat warning, see ªEngine Overheatingº in
the Index.

Towing Your Vehicle
CAUTION:
To help avoid serious personal injury to you
or others:

Never let passengers ride in a vehicle that is
being towed.

Never tow faster than safe or posted speeds.

Never tow with damaged parts not
fully secured.

Never get under your vehicle after it has
been lifted by the tow truck.

Always secure the vehicle on each side with
separate safety chains when towing it.

Use only the correct hooks.
NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment. When using wheel-lift
equipment on a vehicle with All
-Wheel-Drive, you must
use a dolly under the rear wheels when towing from the
front and under the front wheels when towing from the
rear. On Rear
-Wheel Drive vehicles observe the
following tow limits of 35 mph (56 km/h) for
50 miles (80 km).
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find an engine coolant temperature gage on
your vehicle's instrument panel. See ªGagesº in
the Index.

6-4
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications. If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog
-check test. (See ªMalfunction
Indicator Lampº in the Index.) If this occurs, return to
your authorized GM dealer for diagnosis to determine
the cause of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or not
the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized GM dealer for service.To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
contribute to clean air. General Motors recommends that
you use these gasolines, particularly if they comply with
the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn't
be covered under your warranty.

2. Remove the instrument panel extension by removing
the two nuts that secure it in place. The nuts are
located at the bottom of the extension on the driver's
and passenger's side corners.3. Remove the screws located near the top on each side
of the extension. Grasp the extension from both sides
and gently remove it.

6-18
6. Remove the two bolts at the engine cover. The bolts
are not supposed to come out of the cover, only from
the front of the dash.
When removing the cover, be careful not to damage
the instrument panel or the trim.
7. Disconnect the AM radio ground strap.8. Grasp the bottom of the cover and slide it rearward.
Then, lift it up and out of the vehicle.
If the seal does not release, use the pull strap on the
driver's side above the rear mount.

6-53 Cleaning Vinyl
Use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt.
You may have to do it more than once.

Things like tar, asphalt and shoe polish will stain if you
don't get them off quickly. Use a clean cloth and a
vinyl/leather cleaner. See your dealer for this product.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let the
leather dry naturally. Do not use heat to dry.

For stubborn stains, use a leather cleaner. See your
dealer for this product.

Never use oils, varnishes, solvent
-based or abrasive
cleaners, furniture polish or shoe polish on leather.

Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the
finish, it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft
cloth or sponge. Commercial cleaners may affect the
surface finish.
Care of Safety Belts
Keep belts clean and dry.
CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
