Selectable After-Run Cooling Feature
Race Cool Down is a feature activated by select-
ing the Race Cool Down button in the radio
within the DRAG OPTIONS.
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 tem-
perature radiator coolant pump remain on after
engine shutdown for a period up to five 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 Cool Down 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:
• when intercooler coolant temperature is
above a calibrated amount and ambient tem-
perature.
• When battery state of charge is above a
threshold that ensures use of Race Cool
down will still result in sufficient cranking
speed.
• The hood is opened.
Selectable Launch Control — Track Use
Only
This vehicle is equipped with a Launch Control
system that is designed to allow the driver to
achieve maximum vehicle acceleration in a
straight line. Launch Control is a form of trac-
tion control that manages tire slip while launch-
ing the vehicle. Torque Reserve is also automati-
cally enabled while using Launch Control and
offers a unique exhaust note. The Torque Re-
serve feature maintains supercharger airflow to
provide faster engine torque response and im-
prove vehicle acceleration. This feature is in-
tended for track use only, where consistent
