If Your Engine Overheats - Jeep Compass Operating Information Manual

4. Connect the opposite end of the negative (-)
jumper cable to a good engine ground (ex-
posed metal part of the discharged vehicle's
engine) away from the battery and the fuel
injection system.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause the
battery to explode and could result in per-
sonal injury. Only use the specific ground
point, do not use any other exposed metal
parts.
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.
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 positive (+) post of
the vehicle with the discharged battery.
5. Reinstall the air intake duct.
If frequent jump-starting is required to start your
vehicle you should have the battery and charg-
ing system inspected at your 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 bat-
tery 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 re-
duce 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 in-
crease engine idle speed.
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.
