2019 DODGE CHALLENGER SRT coolant temperature

•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder immediately if
the brake system warning light indicates system failure. Check the fluid level in the master cylinder when perform-
ing underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the requirements
described on the brake fluid reservoir. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed con-
tainer to avoid contamination from foreign matter or
moisture.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.

NOTE:The only time the shift light comes on, is when the
shifter is placed into Sport Mode. It will not work with
paddle shifters.
The Shift Light RPM Set-Up allows you to set the shift light
to actuate for gears 1, 2, 3, 4, and 5-8. By pressing and
releasing the up/down arrow buttons on the touchscreen
above and below each listed gear, the RPM values will change in increments of 250 RPM. Pressing and holding the
arrows will change the RPM values in increments of 500
RPM, ranging from 2000–6000 RPM (6.2L) and 2000–6250
(6.2L High Output). The Shift Light setup screen may only
be accessed if the feature is enabled. Press the “Reset to
Factory Default” button on the touchscreen to change back
to factory settings, or press the “Shift Light Off” button on
the touchscreen to turn the system off completely.
Race Cooldown — If Equipped
Race Cooldown is a selectable After-Run Cooling Feature.
Race Cooldown is a feature activated by selecting the Race
Cooldown button under Race Options within the Drive
Modes pages.
To enable this feature, the vehicle will check to ensure the
engine is off, the hood is closed, the status of the battery
and system are good, and determine if cooling is required.
After making a pass down the drag strip, this feature helps
cool the car after the engine has been shut down. The
radiator fan and low temperature radiator coolant pump
remain on after engine shutdown for a period up to 10
minutes or until target temperature is reached.

A graph in the radio can show the resulting intercooler
coolant temperature in real time while the vehicle ignition
is in run position with the engine off.
NOTE: Race Cooldown feature (After-Run) will only come
on with engine off. The temperature will display with
engine running also, but After-Run Cooling will not be
functioning.This feature will automatically deactivate after extended
driving at road speeds, or when one or more of the
following conditions apply:
•
If coolant temperatures reaches the target temperature
and cooling is no longer required.
• If battery voltage or state of charge drops below a
threshold.
• The hood is opened.
