1994 BUICK CENTURY Owners Manual

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
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 Buick 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.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on
the rear edge of the driver’s door tells you the
proper size, speed rating and recommended inflation
pressures for the tires
on your vehicle. It also gives you
important information about the number
of people that
can be in your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight
of all occupants, cargo, and all
nonfactory-installed options.

The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating). The GVWR includes the
weight of the vehicle,
all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front or rear
axle.
And, if you do have a heavy load, you should spread it
out. Don’t carry more than
160 pounds (72 kg) in the
sedan
trunk or 300 pounds (136 kg) in the six-passenger
wagon rear area.
