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 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 brak-
ing 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.
SELEC-TRACK — IF EQUIPPED
Description
Selec-Track combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.
Push the SRT button and the available drive modes will
show up on the radio touchscreen.
Refer to the Drive Modes for further information.
Selec-Track consists of the following positions:
•
SPORT – Dry weather, on-road calibration. Perfor-
mance based tuning that provides a rear-wheel
drive feel but with improved handling and accelera-
tion over a two-wheel drive vehicle. This feature will
reset to AUTO upon an ignition cycle.
•
SNOW – Tuning set for additional stability in inclem-
ent weather. Use on and off-road on loose traction
surfaces such as snow. This feature will reset to
AUTO upon an ignition cycle.
•
AUTO – Fully automatic full time four-wheel drive
operation can be used on and off-road. Balances
traction with seamless steering feel to provide
improved handling and acceleration over two-wheel
drive vehicles.
