Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into “P’
(Park) yet.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift to “P” (Park).
Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system, and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before
you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

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 @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
should have your brake system fixed, since a leak means
that sooner or later your brakes won't work well, or
233
ProCarManuals.com

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.
a LAUTION:
1
If you have too much brake flui,, I. ;an sblll orl
the engine. The fluid will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic
-stem.
When your brake fluid falls to a low level, your brake
warning light will come 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
N0.1052535). Use new brake fluid from a sealed
container only.
0
0
DOT-5 silicone brake fluid can damage
your vehicle. Don’t use it.
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.
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 Buick 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
234
ProCarManuals.com

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 Bukk has a Delco Freedoma 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.

INSPECTION
OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
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. Also inspect other brake
parts, including calipers, parking
brake, etc. Check parking brake
adjustment. You may need to have
your brakes inspected more often
if
your driving habits or conditions
result
in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also, if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light”
in
the Index. If your vehicle is equipped
with anti-lock brakes and the
anti-lock brake system warning light
stays on, comes on or flashes,
something may be wrong with the
anti-lock brake system. See
“Anti-Lock Brake System Warning
Light”
in the Index.

Lubricants
