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
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 G-Force Gauge
in the HUD display, apply
the brakes 10 times
starting at 100 km/h
(60 mph) to 50 km/h
(30 mph) while
decelerating at 0.4g.
SeeHead-Up Display (HUD)
136. This is a medium
brake application. Drive for
at least 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.
