100 STARTING AND OPERATING
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 conditions is recommended. Tire
pressure can be monitored 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 friction
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
minimal 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 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 brake pads installed on old rotors require a
burnish. New rotors installed with old brake pads
should be burnished at the track or driven for
300 miles (485 km) of city driving 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.
FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine's eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs.
NOTE:
This system may take some time to return to full function-
ality after a battery disconnect.
POWER STEERING
The electric power steering system will provide increased
vehicle response and ease of maneuverability. The power
steering system adapts to different driving conditions and
adjusts accordingly.
Alternate electric power steering efforts can be selected
through the Uconnect System
Ú page 135.
If the Electric Power Steering warning icon is displayed
and the “SERVICE POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE SYSTEM” message is
displayed within the instrument cluster display, this
indicates the vehicle needs to be taken to the dealer for
service
Ú page 80.
NOTE:
Even if the power steering assistance is no longer oper-
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
If the condition persists, see an authorized dealer for
service.
If the Steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is displayed on
the instrument cluster screen, this indicates an over
temperature condition in the power steering system. Once
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
