Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected, the cause
should be located and corrected immediately.
100 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

6. Park/Headlight ON Indicator
This indicator will illuminate when the park
lights or headlights are turned on.
7. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
8. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
254 UNDERSTANDING YOUR INSTRUMENT PANEL

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.

STARTING AND OPERATING 367

•Prior to each track event/day, verify all fluids are at
the correct levels. Refer to “Fluid Capactites” in Main-
taining Your Vehicle for further information.
•Prior to each track event, verify the front and rear
brake pads have more than½pad thickness remain-
ing. If the brake pads require changing, please burnish
prior to track outing at full pace.
•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 1 cool down lap using minimal
braking.
•If equipped with a removable lower front fascia grille,
it is recommended to remove it for track use during
warm/hot weather to improve cooling airflow to
critical powertrain and cooling system components.
•All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion system, brake system, prop shaft, and½shaft
boots should be checked for wear or damage after
every track event.
•Track usage results in increased operating tempera-
tures of the engine, transmission, clutch – if equipped,
driveline and brake system. This may affect noise
(NVH) countermeasures designed into your vehicle.
New components may need to be installed to return
the system to the original NVH performance.
•Tire pressure:
•40psi hot, recommend 32psi front, 30psi rear cold

STARTING AND OPERATING 395

NOTE:It is recommended that you target 40psi Hot Tire
Pressure at the conclusion of each track session. Starting
at 32psi Front & 30psi Rear Cold and adjusting based on
ambient & track conditions is recommended. Tire pres-
sure can be monitored via the Driver Information Display
(DID) 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 com-
ponents are installed:
1. Use one track session to burnish brakes by driving at
75% speed. Brake at approximately 0.60-0.80g max
without ABS intervention.
2. Lap the track in this manner until you start smelling
the brakes. Continue for another½lap at speed, then
do a two lap cool down with minimal brake applies.
Make sure the brakes are not smoking. If they are, do
another cool down lap.
3. Do not continue for more than 1 full burnishing lap
after you start smelling the brakes. Do not get them
smoking heavily. This will get them too hot and affect
their life negatively in future track use.
4. Allow vehicle to sit and cool in the paddock for at least
30 min. If an infrared thermal gun is available, allow
rotors to cool to 200°F before going back out.
5. There should be a thin, ash layer when inspecting the
pads installed in the caliper. Having the ash layer go
more than half the thickness of the pad material
indicates too aggressive of a burnish.
396 STARTING AND OPERATING

Rain Brake Support
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It only functions when the
windshield wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is cycled to the ON/
RUN position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
