Replacing Brake System Parts
The braking system on a 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. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
GM replacement parts. If you do not, 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 have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery. When it
is time for a new battery, get one that has the
replacement number shown on the original battery’s
label. We recommend an ACDelco

battery. See Engine Compartment Overview on
page 5-12 for battery location.
Warning: Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands
after handling.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly hurt if
you are not careful. See Jump Starting on
page 5-44 for tips on working around a battery
without getting hurt.
After a power loss, such as disconnecting the battery
or removing the maxi fuses in the power distribution fuse
block, the following steps must be performed to calibrate
the electronic throttle control. If this is not done, the
engine will not run properly.
1. Turn the ignition key to ON. Do not start the engine.
2. Leave the ignition in ON for at least three minutes
so that the electronic throttle control will cycle and
re-learn its home position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least 30 seconds.
