If Your Engine Overheats - Jeep GLADIATOR 2020 Owner's Manual

304 IN CASE OF EMERGENCY
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine above
2,000 rpm since it provides no charging
benefit, wastes fuel, and can damage booster
vehicle engine.
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
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 discharged vehicle.
5. Reinstall the protective cover over the
remote positive (+) post of the discharged
vehicle.
If frequent jump starting is required to start your
vehicle you should have the battery and
charging system tested 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, shift transmis-

sion into NEUTRAL (N) , but do not increase
engine idle speed.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
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.
