214 DRIVING AND OPERATING
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a dry
boiling point greater than 279 °C
(534 °F). After conversion to the high
performance brake fluid, follow the
brake fluid service recommendations
outlined by the fluid manufacturer. Do
not use silicone or DOT-5 brake fluids.
Check the fluid level before each
competitive driving event.
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
Stage 1 : The Driver Information
Center (DIC) displays a Reduce
Braking to Avoid Overheating
message and brake pedal effort and
travel is increased. When the message
displays, the driver should decrease
brake pedal pressure.
Stage 2 : The Driver Information
Center (DIC) displays a Brakes
Overheated Service Now message that
the brake fluid temperature is
excessive and is about to boil. The
system increases brake pedal effort
and travel, and will also limit vehicle
speed. The driver should immediately
start a cool down lap if on the track.
If this message displays, take the
vehicle to be serviced at your dealer.
Brake Burnishing
To prepare the brake system for track
events and racing, complete the
appropriate high performance brake
burnishing procedure described below.
New brake pads must be burnished
before racing or other competitive
driving.
Caution
These procedures are specific to the
V-Series with performance brake
linings package. This procedure
should not be run on other models
as damage may result.
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 0 222.
When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the
brake pads will smoke and produce an
odor. The braking force and pedal
travel may increase. After the
procedure is complete, the brake pads
may appear white at the rotor contact.
Run this procedure in a safe manner
and in compliance with all local and
state ordinances/laws regarding motor
vehicle operation. Run this procedure
only on dry pavement.
