When to Replace the Dual Clutch
Transmission Fluid Filter
This vehicle has a computer that indicates
when to change the transmission external
canister fluid filter. This is based on the
number of miles driven as outlined in the
Service and Maintenance section. For the
fluid filter life system to work properly, the
system must be reset every time the filter is
replaced. When the system has calculated
that the external canister filter is near the
mileage interval, a REPLACE TRANSMISSION
OIL FILTER SOON message comes on. Replace
the external canister filter before the
indicator reaches 0%.
Failure to replace the transmission filter at
required intervals could lead to suboptimal
transmission performance. Your dealer has
trained service technicians who will replace
the external canister filter and reset the
system. If the system is ever reset
accidentally, the filter should be replaced
according to the service intervals indicated
in the Service and Maintenance section until
the next filter change. If the next filter
change is the first, follow the service
interval until the second filter change,
resetting the filter life system at each filter
change.
How to Reset the Dual Clutch

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.

260 Vehicle Care
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. SeeBrakes0257.
To turn off the brake pad life system: 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 092.
2. Select the Brake Pad Life menu.
3. Select DISABLE.
To turn the brake pad life system back on,
follow the above steps but select ENABLE in
Step 2.
Electronic Brake Pad Sensor System
(Z06/Z07 with J57 Carbon Ceramic Brake
Rotors)
The brake pads have electronic brake pad
wear sensors, when the brake pads need to
be replaced, a message displays in the
Driver Information Center (DIC) which says
“Service Brakes Worn”.
When the message displays, install new
brake pads and brake pad wear sensors on
the vehicle.
When the ignition is turned on after new
brake pads and brake pad wear sensors are
installed, the message should no longer
display.
The brake pad sensor system can only be
reset by replacing the brake pads and brake
pad wear sensors.
Brake Fluid
The brake master cylinder reservoir is filled
with GM approved DOT 4 brake fluid as
indicated on the reservoir cap. See
Underhood Compartment Overview 0234 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.
.A fluid leak in the brake hydraulic system.
Have the brake hydraulic system fixed.
With a leak, the brakes will not
work well.

Park Brake and P (Park)
Mechanism Check
{Warning
When you are doing this check, the
vehicle could begin to move. You or
others could be injured and property
could be damaged. Make sure there is
room in front of the vehicle in case it
begins to roll. Be ready to apply the
regular brake at once should the vehicle
begin to move.
Park on a fairly steep hill, with the vehicle
facing downhill. Keeping your foot on the
regular brake, set the parking brake.
.To check the parking brake's holding
ability: With the engine running and the
transmission in N (Neutral), slowly remove
foot pressure from the regular brake
pedal. Do this until the vehicle is held by
the parking brake only.
.To check the P (Park) mechanism's holding
ability: With the engine running, shift to
P (Park). Then release the parking brake
followed by the regular brake.
Contact your dealer if service is required.
Wiper Blade Replacement

Liftgate
Headlamp Aiming
Front Headlamp Aiming
Headlamp aim has been preset and should
need no further adjustment.
If the vehicle is damaged in a crash, the
headlamp aim may be affected.
If adjustment to the headlamps is necessary,
see your dealer.
Bulb Replacement
LED Lighting
This vehicle has all LED lamps. For
replacement of any LED lighting assembly,
contact your dealer.
Electrical System
Electrical System Overload
The vehicle has fuses to protect against an
electrical system overload.
When the current electrical load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the current load
returns to normal or the problem is fixed.
This greatly reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses protect the wires that provide the
power to the devices in your vehicle.
If there is a problem on the road and a fuse
needs to be replaced, the same amperage
fuse can be borrowed. Choose some feature
of the vehicle that is not needed to use and
replace it as soon as possible.

parts to which it is fastened, can
cause wheel nuts to become loose
over time. The wheel could come off
and cause a crash. When changing a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, a cloth
or paper towel can be used; however,
use a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the inner diameter of the
wheel hub opening with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or rust
buildup.
{Warning
Do not apply grease to the wheel
mounting surface, wheel conical
seats, or the wheel nuts or bolts.
Grease applied to these areas could
cause a wheel to become loose or
come off, resulting in a crash.
