Brake Pad Life System
W
h
en to Change Brake Pads
This vehicle has asystem that estimates the
remaining life of the front and rear brake
pads. Brake pad life remaining is displayed as
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. Place the vehicle in P (Park).
2. From the infotainment home screen, select
Vehicle Status >Maintenance >Brake Pad
Life. See Vehicle Status 3126.
3. Touch either RESET FRONT BRAKE PADS or
RE
SET REAR BRAKE PADS.
4. Touch RESET again to confirm. The
percentage of brake pad life remaining will
change to 100%.
5. Repeat for the other set of brake pads 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 3330.
To turn off the brake pad life system:
1. Place the vehicle in P (Park).
2. From the infotainment home screen, select
Vehicle Status >Maintenance >Brake Pad
Life. See Vehicle Status 3126.
3. Touch Turn Off.
To turn the brake pad life system back on,
fo
llow the same steps and touch Turn On in the
last step.
Brake Fluid
The brake master cylinder reservoir is filled
wi
th GM approved DOT 4brake fluid as
indicated on the reservoir cap. See Engine
Compartment Overview 3317 for the location
of the reservoir.
Checking Brake Fluid
With the vehicle in P(Park) on alevel surface,
the brake fluid level should be between the
minimum and maximum marks on the brake
fluid reservoir.
There are only two reasons why the brake fluid
level in the reservoir may go down:
•
Normal brake lining wear. When new
linings are installed, the fluid level goes
back up.
