WARNING!(Continued)
•If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
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. Inspect the tread and sidewall for cuts
and cracks. Check the wheel nuts for tightness. Check the
tires for proper 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

Tire Pressure Monitoring Indicator Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring Indicator Light
The warning light switches on and a message is displayed to indicate that the tire pressure is
lower than the recommended value and/or that slow pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indica-
tions corresponding to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair immedi-
ately using the dedicated tire repair kit and contact
your authorized dealership as soon as possible.
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. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a signifi-
cantly 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.
126 UNDERSTANDING YOUR INSTRUMENT PANEL

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion 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 subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction
indicator is illuminated, the system 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 equip-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment 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 inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealership to have your sensor function checked.

188 STARTING AND OPERATING

STREET/RACE MODE — IF EQUIPPED
This vehicle is equipped with a two mode electronic
controlled damping system. This system allows for a
compliant street suspension damping setting or a firmer
race suspension damping setting. When in street mode the
system will automatically shift the suspension dampers to
the firmer Race damping setting during some hard accel-
eration and braking situations. There are two modes of
operation:
•Street Mode — This mode will give a sporty, but
comfortable ride. This mode is driver selectable when
the vehicle is placed in STREET mode (push the
“STREET” button on the Instrument Panel). This mode
is intended for a smoother ride on the various types of
pavement and road conditions while still providing
damping levels appropriate extreme capabilities.
• Race Mode — This mode is driver selectable when the
vehicle is placed in RACE mode (push the “RACE”
button on the Instrument Panel). This mode is for track
use only and will supply maximum grip to the tires. NOTE:
•
With the ignition in the ON/RUN position, the suspen-
sion damping system will be in the last mode the system
was in when the vehicle was turned off. The driver can
select either Street or Race damping mode at any time.
• The suspension mode will lock and stay in whatever the
driver selects even when the ignition is turned off and
the car restarted.
• The RACE setting will provide a much firmer ride.
• When RACE mode is enabled, a Shock symbol with
“RACE” next to it will light up in the instrument cluster.
LAUNCH MODE
This system maximizes acceleration traction for straight
line racing.
1. Bring the vehicle to a complete stop on a level track surface with the engine running.
2. Set the steering wheel for straight ahead driving.
3. Fully depress the clutch and select the first gear posi- tion.

WARNING!(Continued)
reckless or dangerous manner, which can jeopardize
the user ’s safety or the safety of others. Only a safe,
attentive, and skillful driver can prevent accidents.
TRACK USE
Guidelines For Track Use
NOTE:Because of the extreme conditions encountered
during track use, any damage or wear associated with
track use is not covered by warranty.
• It is recommended that the shocks be operated in RACE
mode, if equipped.
• ESC is track capable in all modes.
Prior To Each Track Event/Day
• Verify all fluids are at the correct levels. Refer to “Fluid
Capacities” in “Maintaining Your Vehicle” for further
information.
• Verify the front and rear brake pads have more than ½
pad thickness remaining. If the brake pads require
changing, please burnish prior to track outing at full
pace. •
Tire pressure:
– 35psi hot recommended. This typically can be achieved with cold pressures between 25 and 29 psi,
depending on driver, track, and ambient conditions.
Conclusion Of Each Track Event
• It is recommended that a brake bleed procedure is
performed to maintain the pedal feel and stopping
capability of your brake system.
• It is recommended that each track outing should end
with a minimum of 1 cool down lap using minimal
braking.
• Following each track session, tires should be inspected
for wear.
NOTE:
• All SRT vehicles are track tested for 24 hours of endur-
ance, however, it is recommended that suspension sys-
tem, brake system, prop shaft, and ½ shaft boots should
be checked for wear or damage after every track event.
198 STARTING AND OPERATING

•Track usage results in increased operating temperatures
of the engine, transmission, clutch, 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.
For ACR models, please review the supplemental manual
for track tips.
DRIVING ON SLIPPERY SURFACES
Acceleration
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
You could lose control of the vehicle and possibly have
a collision. Accelerate slowly and carefully whenever
there is likely to be poor traction (ice, snow, wet, mud,
loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should be
observed:
1. Slow down during rainstorms or when roads are slushy.
2. Slow down if road has standing water or puddles.
CAUTION!
Driving your vehicle through deep puddles at speeds
over 5 mph (8 km/h), may cause water to be ingested
into the engine. This can cause severe engine damage.
3. Replace tires when tread wear indicators first become visible.
4. Keep tires properly inflated.
5. Maintain enough distance between your vehicle and the vehicle in front of you to avoid a collision in a sudden
stop.
