Push and release the up or down arrow button
until the Trip A or Trip B icon is highlighted in
the instrument cluster display (Toggle left or
right to select Trip A or Trip B). Push and
release the OK button to display the Trip
information.
WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive and/or alternative
to the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first
if applicable. The system check menu may
appear different based upon equipment op-
tions and current vehicle status. Some tell-
tales are optional and may not appear.
Red Warning Lights
— Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four
to eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a
single chime when a fault with the air bag has
been detected, it will stay on until the fault is
cleared. If the light is either not on during
startup, stays on, or turns on while driving,
have the system inspected at an authorized
dealer as soon as possible.
— Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking
brake is applied, that the brake fluid level is
low, or that there is a problem with the
anti-lock brake system.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
73

ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver
or front passenger seat belt remains unbuck-
led, the Seat Belt Reminder Light will flash or
remain on continuously and a chime will
sound.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
— Transmission Temperature Warning
Light — If Equipped
This warning light will illuminate to warn of a
high transmission fluid temperature. This
may occur with strenuous usage such as
trailer towing. If this light turns on, stop the
vehicle and run the engine at idle or slightly
faster, with the transmission in PARK or
NEUTRAL, until the light turns off. Once the
light turns off, you may continue to drive
normally.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause
a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
— Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
Yellow Warning Lights
— Service Adaptive Cruise Control
Warning Light
This light will turn on when the ACC system is
not operating and needs service. For further
information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— Anti-Lock Brake (ABS) Warning
Light
This warning light monitors the Anti-Lock
Brake System (ABS). The light will turn on
when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and may stay on for as
long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service is
required as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warn-
ing Light is not also on.
GETTING TO KNOW YOUR INSTRUMENT PANEL
76

WARNING!
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
with the accelerator, brake, or clutch
pedals.
• 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 accelera-
tor, 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 se-
cured 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 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 the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected
immediately.
WARNING!
To prevent SERIOUS INJURY or DEATH
when using “Track-Use” parts and equip-
ment:
• NEVER use any “Track-Use” equipment
on public roads. FCA does not authorize
the use of “Track-Use” equipment on
public roads.
• The intended use of “Track-Use” parts is
for race vehicles on race tracks. To help
ensure the safety of the race driver, en-
gineers should supervise the installation
of “Track-Use” parts.
• FCA does not authorize the installation
or use of any part noted as “Track-Use”
on any new vehicle prior to its first retail
sale.
143

Launch control will be active until the vehicle
reaches 62 mph (100 km/h), at which point
the Electronic Stability Control (ESC) system
will return to its current ESC mode.
Launch control will abort before launch
completion, display “Launch Aborted” in the
cluster under any the following conditions:
• The accelerator pedal is released during
launch.
• The ESC system detects that the vehicle is
no longer moving in a straight line.
• The “ESC OFF” button is pressed to change
the system to another mode.
NOTE:
After launch control 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 trac-
tion. Damage to the transmission may oc-
cur.
Guidelines For Track Use
NOTE:
Because of the extreme conditions encoun-
tered 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 perfor-
mance 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 flu-
ids 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 re-
quire 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 ther-
mal 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 pow-
ertrain and cooling system components.
• All SRT vehicles are track tested for
24 hours of endurance, however, it is rec-
ommended 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,
driveline and brake system. This may affect
noise vibrations and harshness (NVH)
countermeasures designed into your ve-
hicle. New components may need to be
installed to return the system to the original
NVH performance.

At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of the coolant reser-
voir, and brake master cylinder; add fluid as
needed.
