2015 DODGE CHALLENGER SRT Owners Manual

•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, and ½ 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, 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 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 another ½ lap at speed, then
5
STARTING AND OPERATING 375

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. 6. Sometimes, a second burnish session is required. If the
pads start smelling in the next track session, reduce
speed and braking decel to burnish targets and follow
step 2-4.
7. New pads installed on old rotors still need to be burnished. 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 re- placed. Resurfacing of the rotors is not recommended,
as it removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, mak-
ing it less robust and increasing the likelihood of
pulsation in further track use.
376 STARTING AND OPERATING

DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. 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 known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
•Slow down during rainstorms or when the roads are
slushy.
• Slow down if the road has standing water or puddles.
• Replace tires when tread wear indicators first become
visible.
• Keep tires properly inflated.
• Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a
sudden stop.
5
STARTING AND OPERATING 377

Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not eliminate,
the amount of wheel slip across a given axle for im-
proved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
CAUTION!
•Due to lower ground clearance, driving your ve-
hicle up steep driveways, approach ramps or near
parking blocks may cause damage to the front
fascia and ground effects.
• Driving through snow more than 4 inches (100 mm)
deep may cause damage to the front fascia and
ground effects.
Flowing/Rising Water
WARNING!
Do not drive on, or cross, a road or a path where
water is flowing and/or rising (as in storm run-off).
Flowing water can wear away the road or path’s
surface and cause your vehicle to sink into deeper
water. Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cautions
and Warnings before doing so.
378 STARTING AND OPERATING

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stopping
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.
CAUTION!
• Always check the depth of the standing water
before driving through it. Never drive through
(Continued)
CAUTION! (Continued)
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. Such
(Continued)

CAUTION!(Continued)
damage is not covered by the New Vehicle Limited
Warranty.
• Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
POWER STEERING — 6.4L ENGINE
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide
light efforts while parking and good feel while driving. If
the electric steering system experiences a fault that
prevents it from providing assist, you will still have the
ability to steer the vehicle manually. Alternate electric power steering efforts can be selected
through the Uconnect® System. Refer to the “Drive
Modes” in this section for further information.
WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.
If the Steering icon is displayed and the “SER-
VICE POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE SYSTEM”
message is displayed within the Driver Infor-
mation Display (DID), this indicates the vehicle needs to
be taken to the dealer for service. Refer to “Driver
Information Display (DID)” in “Understanding Your
Instrument Panel” for further information.
380 STARTING AND OPERATING

NOTE:
•Even if the power steering assistance is no longer
operational, 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 your authorized dealer for
service.
POWER STEERING — 6.2L SUPERCHARGED
ENGINE
The hydraulic power steering system is sport tuned and
will give you good vehicle response and increased ease of
maneuverability in tight spaces. The system will provide
mechanical steering capability if power assist is lost. If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•
Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
5
STARTING AND OPERATING 381

WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
FUEL SAVER TECHNOLOGY — 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 or additional driving skills required.NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK or REVERSE (manual transmission only) position.
When the parking brake is applied and the ignition
switch is in the ON position (RUN position with Keyless
Enter-N-Go™), the “Brake Warning Light” in the instru-
ment cluster will illuminate.
NOTE:
• When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake Warning Light” will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
