If Your Engine Overheats - Dodge CHALLENGER 2021 Owner's Manual

6. Once the engine is started, follow the
disconnection procedure below.
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the
jumper cable from the remote negative (-)
post of the vehicle with the discharged
battery.
2. Disconnect the opposite end of the negative
(-) jumper cable from the negative (-) post of
the booster battery.
3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.
4. Disconnect the opposite end of the positive
(+) jumper cable from the remote positive
(+) post of the vehicle with the discharged
battery.
If frequent jump starting is required to start your
vehicle you should have the battery and
charging system inspected at an authorized
dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle's battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle's battery
will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.

IF YOUR ENGINE OVERHEATS

If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
IN CASE OF EMERGENCY
On the highways — slow down.

In city traffic — while stopped, place the trans-

mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.

The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to

maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
