have the vehicle serviced. Do not drive the
vehicle if the red parking brake status light
is flashing. See your dealer.
If the amber service parking brake warning
light is on, press the EPB switch. Continue to
hold the switch until the red parking brake
status light remains on. If the amber service
parking brake warning light is on, see your
dealer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pressed. If the switch is
pressed until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system, or at the request of other
safety functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:1. Turn the ignition on or to accessory mode. 2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red parking
brake status light is off.
If the amber service parking brake warning
light is on, release the EPB by pressing and
holding the EPB switch. Continue to hold the
switch until the red parking brake status
light is off. If either light stays on after
release is attempted, see your dealer.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if the
vehicle is running, placed into gear, and an
attempt is made to drive away. Avoid rapid
acceleration when the EPB is applied, to
preserve parking brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See Defensive Driving
0 170.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) prevents the vehicle from
rolling in an unintended direction during the
transition from brake pedal release to

Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnishing procedure or damage may
occur to the powertrain/engine. See New
Vehicle Break-In 0189.
Caution
Brake fade can occur during this burnish
procedure and can cause brake pedal
travel and force to increase. This could
extend stopping distance until the brakes
are fully burnished.
Completing the following procedure as
instructed will not damage the brakes. The
brake pads may smoke and produce an odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
1. Using the Friction Bubble gauge, apply the brakes 10 times starting at 100 km/h
(60 mph) to 50 km/h (30 mph) while
decelerating at 0.4g. This is a medium
brake application. Drive for at lest 0.5 km
(0.3 mi) between applying the brakes.
2. If further cleanup of the brake discs is needed, repeat this procedure with 0.7g
applications.
As with all high performance brake systems,
some amount of brake squeal is normal.
Brake Pad Life System (If
Equipped)
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
displays, 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) 092.
2. Select the Brake Pad Life menu.
3. Select front or rear pads as appropriate.
4. Select YES on the confirmation message. Repeat for the pads on the other axle if
they were also replaced.

Caution
If any accessories are left on or plugged
in during the jump starting procedure,
they could be damaged. The repairs
would not be covered by the vehicle
warranty. Whenever possible, turn off or
unplug all accessories on either vehicle
when jump starting.
3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged
into the accessory power outlet. Turn off
the radio and all lamps that are not
needed. This will avoid sparks and help
save both batteries. And it could save
the radio!
4. Open the hood. See Hood017.
5. Release the four clips for the left and
right outer covers.
6. Release the five clips and remove theouter cover to access the battery. 7. Locate the battery positive (+) and
negative (−) terminals.
8. Check that the jumper cables do not have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged too.
9. Open the discharged battery positive (+) terminal trim cover and connect one end
of the positive (+) cable.
10. Do not let the other end of the positive (+) cable to touch metal.
Connect it to the good battery
positive (+) terminal.
11. Connect one end of the negative (−) cable to the good battery negative (−)
terminal.
Do not let the other end touch anything
until the next step.
12. Connect the other end of the negative (−) cable to the discharged battery
negative (−) terminal.
13. Start the vehicle with the good battery and run the engine for a while.
14. Try to start the vehicle that had the discharged battery. If it will not start
after a few tries, it probably needs
service.

.Obstruction of the GPS can occur in a
large city with tall buildings; in parking
garages; around airports; in tunnels and
underpasses; or in an area with very
dense trees. If GPS signals are not
available, the OnStar system should still operate to call OnStar. However, OnStar
could have difficulty identifying the exact
location.
.In emergency situations, OnStar can use
the last stored GPS location to send to
emergency responders.
A temporary loss of GPS can cause loss of
the ability to send a Turn-by-Turn
Navigation route. The Advisor may give a
verbal route or may ask for a call back after
the vehicle is driven into an open area.
Cellular and GPS Antennas
Cellular reception is required for OnStar to
send remote signals to the vehicle. Do not
place items over or near the antenna to
prevent blocking cellular and GPS signal
reception.
Unable to Connect to OnStar Message
If there is limited cellular coverage or the
cellular network has reached maximum
capacity, this message may come on. Press
Qto try the call again or try again after
driving a few miles into another
cellular area.
