•
Prior to each track event, verify the front and rear
brake pads have more than half pad thickness
remaining. If the brake pads require changing, com-
plete a brake burnish procedure prior to track outing
at full pace.
NOTE:
Use of DOT 4 brake fluid is suggested for extended
track use due to increased thermal capacity.
•
At the conclusion of each track event, it is recom-
mended that a brake bleed procedure is performed
to maintain the pedal feel and stopping capability of
your Brembo High Performance brake system.
•
It is recommended that each track outing should
end with a minimum of one cooldown lap using
minimal braking.
•
All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that sus-
pension system, brake system, prop shaft, and half
shaft boots should be checked for wear or damage
after every track event.
•
Track usage results in increased operating tempera-
tures of the engine, transmission, driveline, and
brake system. This may affect Noise Vibration
Harshness (NVH) countermeasures of your vehicle.
New components may need to be installed to return
the system to the original NVH performance.
•
Tire pressure:
○ Recommended tire pressure of 33 psi (230 kPa)
when tires are cold, or below 42 psi (290 kPa)
when hot.
NOTE:
It is recommended that you target below 42 psi
(290 kPa) when tires are hot at the conclusion of
each track session. Starting at 33 psi (230 kPa)
cold and adjusting based on ambient and track con-
ditions is recommended. Tire pressure can be moni-
tored via the instrument cluster display and can
assist with adjustments.
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 fric-
tion components are installed:
1. Use one track session to burnish brakes by driving
at 75% speed. Brake at approximately 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 mini-
mal brake applications. Ensure the brakes are not
smoking. If they are, complete another cooldown
lap.
3. Getting the brakes to smoke is an 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 avail-
able, 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 brak-
ing deceleration rate to burnish targets and follow
steps 2-4.
7. New pads installed on old rotors still need to be bur-
nished. 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 (6.4L only).
The Paddle Shifters will be disabled while in ECO Mode.
•
ECO is only available in AUTO Mode.
•
Changing the Drive Mode will deactivate ECO.
