Brake Pad Life System
When to Change Brake Pads
If equipped, this system estimates the
remaining life of the front and rear
brake pads. Brake pad life is displayed
in the Driver Information Center
(DIC), along with a percentage for
each axle. The system must be reset
every time the brake pads are
changed.
When the system has determined that
the brake pads need to be replaced, a
message will display, which may
include mileage remaining.
Brake pads should always be replaced
as complete axle sets.
How to Reset the Brake Pad Life
System
The system will automatically detect
when significantly worn brake pads
are replaced. When the ignition is
turned on after new pads and wear
sensors are installed, a message will
display. Follow the prompts to reset
the system.
The brake pad life system can also be
manually reset:
1. Display Brake Pad Life on the
DIC. See Driver Information Center
(DIC) 0 132.
2. Press and hold SEL. Select front
or rear pads as appropriate.
3. Select YES on the confirmation
message. Repeat for pads on the
other axle if they were also
replaced.
How to Disable the Brake Pad
Life System
The brake pad life system can be
turned off. This may be necessary if
aftermarket brake pads without wear
sensors are installed. When the
system is turned off, the front and
rear brake pad life percentages will
not display. However, the built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn can still determine when the
pads should be replaced. See Brakes
0 290.
To turn off the brake pad life system:
1. Display Brake Pad Life on the
DIC. See Driver Information Center
(DIC) 0 132.
2. Select DISABLE.
To turn the brake pad life system back
on, follow the above steps but select
ENABLE in Step 2.
Brake Fluid
The brake master cylinder reservoir is
filled with GM approved DOT 3 brake
fluid as indicated on the reservoir cap.
See Engine Compartment Over view
