power steering CHEVROLET ASTRO PASSENGER 1994 1.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Power Door Locks
If your vehicle has
power door locks,
push the power door
lock switch to lock or
unlock all the doors at
once.
The Power Door Lock switch will not lock or unlock the rear hatch and split
panel doors. You must use the
HATCH REL switch. See “Hatch Release
Switch” in the Index.
Every vehicle with power door locks has a pulse lock system. A pulse lock
system works like this:
If the sliding door is open and you push the power door lock switch, the
sliding door will not lock immediately. After you close the door, the system
comes on and, in about five seconds, locks the sliding door.
All models have overriding door locks. When a door is locked, the door
handle will not work the latch. This will help stop a door from being
accidentally opened. However, power door locks do not affect the operation
of the hatch.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your door and set the
locks from inside. Then get out and close the door.
Rear Hatch and Split-Panel Doors
If you have this option, your vehicle must be in either “P” (Park) or
“N’ (Neutral) to release the hatch and unlock the split-panel doors. If your
battery is dead, the hatch and doors will not open, even from the outside
with a key.
To release the hatch and unlock the doors from the inside of the vehicle,
press
the HATCH REL switch on the instrument panel just left of the
steering column.

Downloaded from www.Manualslib.com manuals search engine As you brake, your computer keeps receiving updates on wheel speed and
controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time you need to get your foot up
to the brake pedal. If you get too close to the vehicle in front of you, you
won’t have time to apply your brakes if that vehicle suddenly slows or
stops. Always leave enough room up ahead to stop, even though you have
anti-lock brakes.
To Use Four-wheel Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down and let anti-lock
work for you. You may feel the brakes vibrate, or you may notice some
noise, but this is normal.
Braking in Emergencies
Use your anti-lock braking system when you need to. With anti-lock, you
can steer and brake at the same time. In many emergencies, steering can
help you more than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine stops or the system is
not functioning, you can steer but it will take much more effort.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
When adding power steering fluid or making a complete fluid
change, always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
To Add
Open the cap labeled
WASHER FLUID
ONLY. Add washer
fluid until the tank is
full.
NOTICE:
When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
Don’t mix water with ready-to-use washer fluid. Water can
cause the solution to freeze and damage your washer fluid
tank and other parts of the washer system. Also, water
doesn’t clean as well as washer fluid.
Fill your washer fluid tank only 3/4 full when it’s very cold.
This allows for expansion, which could damage the tank if it is
completely full.
Don’t use radiator antifreeze in your windshield washer. It
can damage your washer system and paint.

Downloaded from www.Manualslib.com manuals search engine Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together
if the vehicle is to have really good
braking. Vehicles we design and test have top-quality
GM brake parts in
them, as your vehicle does when it is new. When you replace parts of your
braking system
- for example, when your brake linings wear down and
you have to have new ones put in
- be sure you get new genuine GM
replacement parts. If you don’t, your brakes may no longer work properly.
For example,
if someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes can change, for
the
worse. The braking performance you’ve come to expect can change in many
other ways if someone puts in the wrong replacement brake parts.
Hydro-Boost Brake System
The power steering pump also powers the Hydro-Boost. Refer to “Power
Steering Fluid”
in the section when checking the fluid level or adding fluid.
Battery
Every new vehicle has a Delco Freedom@ battery. You never have to add
water to one
of these. When it’s time for a new battery, we recommend a
Delco Freedom@ battery. Get one that has the catalog number shown on the
original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
Contact your dealer to learn how to prepare your vehicle for longer storage
periods.

Downloaded from www.Manualslib.com manuals search engine Periodic Maintenance Inspections
Listed below are inspections and services which should be perfo\
rmed at
least twice a year (for instance, each spring and fall). You should let your
GM dealer’s service department or other qualified service center do these
jobs. Make sure any necessary repairs are completed at once.
Steering and Suspension Inspection? - Inspect front and rear suspension
and steering system for damaged, loose or missing parts, signs of wear or
lack of lubrication. Inspect power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Lubricate the steering linkage.
Accelerator Control System - Lubricate all pivot points with engine oil,
except the
TBI throttle shaft. Do not lubricate the cam pulley. Remove all
external deposits from pulley.
Do not oil any accelerator or cruise control
cables. Replace any cables that have high effort or excessive \
wear.
Exhaust System Inspection - Inspect the complete system. Inspect the
body near the exhaust system. Look for broken, damaged, missing or
out-of-position parts, as well as open seams, holes, loose conn\
ections or
other conditions which could cause a heat buildup
in the floor pan or could
let exhaust fumes seep into the passenger compartments. See “\
Engine
Exhaust”
in the Index.
Drive Axle Service - Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (all-wheel drive) Inspection? - Every 12 months or at oil
change intervals, check front axle and transfer case and add l\
ubricant when
necessary. Oil the control lever pivot point (except
L Van) and all exposed
control linkage. Check vent hose at transfer case for kinks and proper
installation.
-F A fluid loss in these systems may indicate a problem. Have them inspected a\
nd
repaired
at once.
