Track burnishing your brakes:
To avoid “green lining fade” during track use,
the brake pads and rotors must have a thermal
burnish for factory-installed components or
when new brake friction components are
installed:
1. Use one track session to burnish brakes
by driving at 75% speed. Brake at approxi-
mately 0.60 - 0.80g max without Anti-Lock
Brake System (ABS) intervention.
2. Complete one lap in this manner until you
start smelling the brakes. Continue for
another half lap at speed, then complete a
two-lap cooldown with minimal brake
applications. Ensure the brakes are not
smoking. If they are, complete another
cooldown lap.
3. Getting the brakes to smoke is indication
that the brakes have overheated and may
negatively affect future track usage.
4. Allow vehicle to sit and cool in the paddock
for at least 30 minutes. If an infrared
thermal gun is available, allow rotors to cool
to 200°F (93.3°C) before returning to the
track.
5. There should be a thin layer of ash when
inspecting the brake pads. Having the ash
layer go more than half the thickness of the
pad material is a sign of an overly
aggressive burnish.
6. Occasionally, a second burnish session is
required. If the brake pads begin to emit an
odor during the next track session, reduce
vehicle speed and braking deceleration rate
to burnish targets and follow steps 2-4.
7. New pads installed on old rotors still need to
be burnished. New rotors installed with old
pads should be burnished at the track or
street driven for 300 city miles to develop
an adequate lining transfer layer on the
rotor surface prior to track use.
8. Rotors that pulsate during track use should
be replaced.
NOTE:
Resurfacing of the rotors is not recommended,
as it removes mass from the rotor, reducing its
thermal capacity. Resurfacing also thins the
rotor cheek, making it less robust and
increasing the likelihood of pulsation in further
track use.
ECO MODE
Press the ECO button on the touchscreen to
activate ECO Mode. ECO Mode modifies the
vehicle’s engine and transmission settings to
provide improved fuel economy with a trade-off
in acceleration performance. Increased engine
exhaust noise and/or vibration may be noticed
while ECO is active. This is normal and a result
of the increased amount of operating
conditions where the vehicle is allowed to
operate in four-cylinder mode.
The Paddle Shifters will be disabled while in
ECO Mode.
ECO is only available in AUTO Mode.
Changing the Drive Mode out of Auto will
deactivate ECO.
ECO will be disabled when another Drive
Mode is selected or ECO button is pushed.
When ECO is activated in AUTO Mode, it will
remain in ECO upon activation of AUTO Mode
from any other mode including across key
cycles. To deactivate, press the ECO button
again.
