2004 CHEVROLET ASTRO CARGO VAN wheel

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P):This position locks your rear wheels.
It’s the best position to use when you start your engine
because your vehicle can’t move easily.
{CAUTION:
It is dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move, even
when you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P). SeeShifting Into Park (P)
on page 2-26. If you are pulling a trailer,
seeTowing a Trailer on page 4-35.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. You have to fully apply your
regular brakes before you can shift from PARK (P) when
the ignition key is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever – push the
shift lever all the way into PARK (P) as you maintain
brake application. Then move the shift lever into the gear
you wish. SeeShifting Out of Park (P) on page 2-28.
2-22

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
seeIf You Are Stuck: In Sand, Mud, Ice or Snow
on page 4-28.
NEUTRAL (N):In this position, your engine doesn’t
connect with the wheels. To restart when you’re
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be covered
by your warranty. Be sure the engine is not running
at high speed when shifting your vehicle.
DRIVE (D):This position is for normal driving. If you
need more power for passing, and you’re:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down. You’ll shift
down to the next gear and have more power.
DRIVE (D) should be used for normal towing.
THIRD (3):This position is also used for normal driving,
however it offers more power and lower fuel economy
than DRIVE (D). You should use THIRD (3) when
carrying a heavy load or driving on steep hills.
SECOND (2):This position gives you more power but
lower fuel economy. You can use SECOND (2) on
hills. It can help control your speed as you go down
steep mountain roads, but then you would also want
to use your brakes off and on.
2-23

If you manually select SECOND (2), the transmission
will drive in second gear. You may use this feature
for reducing torque to the rear wheels when you
are trying to start your vehicle from a stop on slippery
road surfaces.
FIRST (1):This position gives you even more
power (but lower fuel economy) than SECOND (2).
You can use it on very steep hills, or in deep snow or
mud. If the shift selector lever is put in FIRST (1),
the transmission won’t shift into rst gear until the
vehicle is going slow enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. If you
are stuck, do not spin the tires. When stopping
on a hill, use the brakes to hold the vehicle in place.Tow/Haul Mode Button
Your vehicle is equipped with a tow/haul button.
The button is located on the end of the column shift
lever. You can use this feature to assist when towing
or hauling a heavy load.
To select the tow/haul mode, press in the button.
The TOW/HAUL light on the instrument panel cluster
will come on. To go back to normal operation, press
the button again. The indicator light on the instrument
panel cluster will go out. SeeTow/Haul Mode Light
on page 3-34for more information.
2-24

All-Wheel Drive
If your vehicle has all-wheel drive, your engine’s
driving power is sent to all four wheels for extra traction
when needed.
This is like four-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle.
It is fully automatic, and adjusts itself as needed for
road conditions.
You may experience a brief vehicle vibration upon
acceleration when driving in slippery conditions.
This is normal and is an indication that the all-wheel
drive system is functioning properly.
Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot.
Push down the parking brake pedal with your left foot.
If the ignition is on, the brake system warning light
will come on.To release the parking brake, hold the regular brake
pedal down. Pull the brake release lever located on
the lower left side of the steering column.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on a hill,
seeTowing a Trailer on page 4-35. That section shows
what to do rst to keep the trailer from moving.

Other Warning Devices
If you carry reective triangles, you can use them to
warn others. Set one up at the side of the road about
300 feet (100 m) behind your vehicle.
Horn
Press the horn symbol in the middle of the steering
wheel to sound the horn.
Tilt Wheel
A tilt steering wheel allows you to adjust the steering
wheel before you drive. You can also raise it to the
highest level to give your legs more room when you exit
and enter the vehicle.The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the steering wheel and pull the
lever. Move the steering wheel to a comfortable
level, then release the lever to lock the wheel in place.

Rear Window Washer/Wiper
Your vehicle may have
this feature. The rear
window washer/wiper is
controlled by using
the switch located on the
instrument panel, next
to the audio system.
To turn the wiper on, slide the switch all the way
up to ON.
For delay wiping, slide the switch up to the center
position next to the word DELAY on the rear wiper
control. The wiper will cycle every nine seconds.
To wash the window, push in on the switch. Window
washer uid will continue to spray until the switch
is released. The wiper will continue with three more
wipes and then return to the setting that was chosen
before the lever was pushed.
Move the switch to OFF to turn off the rear
window washer.The rear window washer uses the same uid bottle as
the front windshield washer. If the uid level is low in the
washer bottle, you may not be able to wash your rear
window. If you can wash your windshield, but not
your rear window, check the uid level.
Cruise Control
Your vehicle may have this feature. With cruise control,
you can maintain a speed of about 25 mph (40 km/h)
or more without keeping your foot on the accelerator.
This can really help on long trips. Cruise control
does not work at speeds below about 25 mph (40 km/h).
When you apply your brakes, the cruise control shuts off.
{CAUTION:
Cruise control can be dangerous where you
can not drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.
3-9

There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. See “Daytime Running Lamps (DRL)” later
in this section for more information.
As with any vehicle, you should turn on the regular
headlamps when you need them.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
tone, turn the instrument panel brightness thumbwheel
all the way down. In the automatic mode, the
headlamps turn off once the ignition key is in OFF.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will make your headlamps come on
at a reduced brightness when the following conditions
are met:
The ignition is on,
the exterior lamp control is off.
the automatic transmission is not in PARK (P),
the light sensor determines it is daytime and
the parking brake is released.
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. Your instrument panel won’t be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the last
chosen headlamp setting that was used.
