NOTE:After launch mode has been aborted, ESC will
return to its current ESC mode.
CAUTION!
Do not attempt to shift when the drive wheels are
spinning and do not have traction. Damage to the
transmission may occur.
Guidelines For Track Use
NOTE: Because of the extreme conditions encountered
during track use, any damage or wear associated with
track use may not be covered by warranty.
• If your SRT vehicle is equipped with Drive Modes, they
will alter the vehicle’s performance in various driving
situations. It is recommended that your vehicle operates
in SPORT or TRACK modes during the track event.
• Prior to each track event/day, verify all fluids are at the
correct levels. Refer to “Fluid Capacities” in “Technical
Specifications” for further information.
• Prior to each track event, 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. NOTE:
Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
• At the 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 Brembo
High Performance brake system.
• It is recommended that each track outing should end
with a minimum of one 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 endur-
ance. However, it is recommended that suspension
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 temperatures
of the engine, transmission, clutch – if equipped, drive-
line and brake system. This may affect noise (NVH)

STARTING AND OPERATING 233

8. Rotors that pulsate during track use should be replaced.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 6.4L 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 or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
HYDRAULIC POWER STEERING — IF EQUIPPED
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 steering
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.
WARNING!
Continued operation with reduced power steering as-
sist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
6
STARTING AND OPERATING 235

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.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should be checked at
every oil change if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an authorized
dealer.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do not
overfill. Use only manufacturer’s recommended power
steering fluid.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steer-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
ELECTRIC POWER STEERING — IF EQUIPPED
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 “Drive Modes” in
this section for further information.
236 STARTING AND OPERATING

Metric Speed (km/h)
•Pushing the SET (-)button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease in 10 km/h increments until the
button is released. The decrease in set speed is reflected
in the instrument cluster display.
NOTE:
• When you override and push the SET (+)button or SET
(-) buttons, the new Set Speed will be the current speed
of the vehicle.
• When you use the SET (-)button to decelerate, if the
engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
• The ACC system applies the brake down to 15 mph
(24 km/h) when following a target vehicle.
• The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting will show in the instrument cluster display.
Distance Setting 4 Bars (Longest)

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door on the left
side of the vehicle. Use a finger to pull open the door. If the
gas cap is lost or damaged, be sure the replacement cap is
for use with this vehicle.
NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the “Malfunction Indicator Light” to
turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
• A poorly fitting fuel filler cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the “Mal-
function Indicator Light (MIL)” to turn on.

the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect on
the way your vehicle steers and handles and the way the
brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed to
the rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
TRAILER TOWING
Trailer towing is not permitted with this vehicle.
RECREATIONAL TOWING (BEHIND MOTORHOME,
ETC.)
Recreational towing (with all four wheels on the ground, or
using a tow dolly) is NOT ALLOWED. The only accept-
able method for towing this vehicle (behind another ve-
hicle) is on a vehicle trailer with all four wheels OFFthe
ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
DRIVING TIPS
Driving On Slippery Surfaces
Information in this section will aid in safe controlled
launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
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 care-
fully whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
270 STARTING AND OPERATING

Shallow Standing Water
Although your vehicle is capable of driving through shal-
low standing water, consider the following Cautions and
Warnings before doing so.
WARNING!
•Driving through standing water limits your vehicle’s
traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’s
braking capabilities, which increases stopping dis-
tances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake
pedal several times to dry the brakes.
• Failure to follow these warnings may result in inju-
ries that are serious or fatal to you, your passengers,
and others around you.
CAUTION!
• Always check the depth of the standing water before
driving through it. Never drive through standing

CAUTION! (Continued)
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 in-
spect your vehicle’s fluids (i.e., engine oil, transmis-
sion, 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 contaminated, as this
may result in further damage. Such 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.
