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.
Brake Master Cylinder
Your brake master cylinder is here. It is filled with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level
in
your master cylinder might go down. The first is that the
brake
fluid goes down to an acceptable level during
normal brake lining wear. When new linings are put
in,
the fluid level goes back up. The other reason is that
fluid
is leaking out of the brake system. If it is, you
6-23

should have your brake system fixed, since a leak means
that sooner or later your brakes won’t work well, or
won’t work at all.
So, it isn’t a good idea to “top off’
your brake fluid. Adding brake fluid won’t correct
a
leak. If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake
linings.
You should add (or remove) brake fluid, as
necessary, only when work is done on the brake
hydraulic system.
When your brake fluid falls
to a low level, your brake
warning light
will come on. A chime will sound if you
try to drive
with this warning light on. See “Brake
System Warning Light”
in the Index. What to
Add
When
you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing it.
I NOTICE:
Don’t let someone put in the wrong kind of
fluid. For example, just a few drops
of
mineral-based oil, such as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to be
replaced.
Brake fluid can damage paint, so be careful
not
to spill brake fluid on your vehicle. If
you do, wash it off immediately. See
“Appearance Care” in the Index.

Brake Wear
Your Aurora has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when
you are pushing on the brake pedal
firmly).
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong
with
your brakes.
Brake linings should always
be replaced as complete
axle sets.
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This could be
a sign of brake trouble.
Brake Adjustment
Every time YOLI apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

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 Aurora 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.
Battery
Every new Aurora 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 replacement number shown
on the original battery’s label. The battery
is located under
the rear seat cushion. To
access the battery, see “Removing the Rear Seat
Cushion”
in the Index. You don’t need to access the
battery to jump start your vehicle. See “Jump Starting”
in the Index.

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot
011 the regular brake, set the
parking brake.
0 To check the parking brake: With the engine running
and transaxle in NEUTRAL (N). slowly remove foot
pressure from the regular brake pedal. Do this until
the vehicle is held by the parking brake only.
0 To check the PARK (P) mechanism’s holding ability:
Shift
to PARK (P). Then release all brakes.
Underbody Flushing
At least every spring. LIS~ plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud
and other debris
can collect.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice
a year (for instance, each
spring and fall). You should let your
GM retailer’s
service department or other qualified service center do
these jobs. Make
SLI~~ any necessary repairs are
completed
at once.
Restraint Systems
Now and then, make sure all your belts, buckles, latch
plates, retractors, anchorages and reminder systems are working properly. Look for any loose parts or damage.
If you see anything that might keep a restraint system
from doing its job, have
it repaired.
Steering, Suspension and Front-
Wheel-Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts,
signs of
wear, or lack of lubrication. Inspect the power steering
lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust 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 connections,
or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust”
in
the Index.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Accelerator and cruise control cables should
not
be lubricated.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hookup, binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect other brake parts, including
calipers, parking brake, etc.
You may need to have your
brakes inspected more often
if your driving habits or
conditions result
in frequent braking.
