If Your Engine Overheats - RAM 1500 2019 User Manual

CAUTION!
Do not connect jumper cable to any of the
fuses on the positive battery terminal. The
resulting electrical current will blow the
fuse.
6. Once the engine is started, remove the
jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the nega-
tive (-) 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 posi-
tive (+) jumper cable from the 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
In any of the following situations, you can
reduce the potential for overheating by
taking the appropriate action.
On the highways — slow down.

In city traffic — while stopped, place the

transmission 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 supple-
ment to the radiator and aids in removing
heat from the engine cooling system.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
