wipers CHEVROLET ASTRO 2004 Owners Manual

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
ªbreak-in.º But it will perform better in the long run
if you follow these guidelines:
·Keep your speed at 55 mph (88 km/h) or less for
the ®rst 500 miles (805 km).
·Do not drive at any one speed Ð fast or
slow Ð for the ®rst 500 miles (805 km). Do not
make full-throttle starts.
·Avoid making hard stops for the ®rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
·Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-35
for more information.
Ignition Positions
With the key in the ignition, you can turn it to ®ve
different positions.
A (ACCESSORY):This position lets you use things like
the radio, power windows and windshield wipers when
the engine is off. To get into ACCESSORY, push in the
key and turn it toward you.
2-17

Turn Signal/Multifunction Lever
The lever on the driver's side of the steering column
includes the following:
·Turn and Lane Change Signals
·Headlamp High/Low-Beam Changer
·Flash-to-Pass
·Windshield Wipers
·Windshield Washer
·Cruise Control (Option)
For information on the exterior lamps, see
Exterior
Lamps on page 3-12.
Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is ®nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
¯ash faster, a signal bulb may be burned out and other
drivers won't see your turn signal.

Windshield Wipers
To operate the windshield
wipers turn the band,
located on the
multifunction lever, upward
or downward.
MIST:Turn the band to MIST for a single wiping cycle.
Hold it there until the windshield wipers start, then let
it go. The wipers will stop after one wipe. If you
want more wipes, hold the band on mist longer.
OFF:Turn the band to turn off the windshield wipers.
LOW (Low Speed):Turn the band to LOW for
steady wiping at low speed.
HIGH (High Speed):Turn the band to HIGH for steady
wiping at high speed.
DELAY:Turn the band to one of the ®ve delay settings
located between OFF and LOW, to choose the
delayed wiping cycle. The closer the band is turned toOFF, the shorter the delay will be. For fewer wipes
choose a setting closer to LOW. Use this setting for light
rain and snow.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
Windshield Washer
L
(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer ¯uid on the windshield, push
the paddle. The wipers will clear the window and then
either stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer ¯uid can form ice on the windshield,
blocking your vision.
The wipers will clear the window and then either stop or
return to your preset speed.

Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to ¯icker on and off, or in some cases to remain
off. If this happens, have your headlamp wiring
checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
Although the circuit is protected from electrical overload,
overload due to heavy snow, etc., may cause wiper
linkage damage. Always clear ice and heavy snow from
the windshield before using the windshield wipers. If
the overload is caused by some electrical problem and
not snow, etc., be sure to get it ®xed.
Power Windows and Other Power
Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is ®xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of ®res caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
Spare fuses and a fuse puller are located in the
underhood fuse block. You can remove fuses with the
fuse puller. Remember to replace any of the spare fuses
you use, so you will have some if you ever need them
again.
If you ever have a problem on the road and don't have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without ± like the radio or
cigarette lighter ± and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is in the engine compartment.
