346 IN CASE OF EMERGENCY
6. Once the engine is started, follow the
disconnecting procedure below.
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.
If frequent jump starting is required to start your
vehicle you should have the battery and charging
system inspected at an authorized dealer.
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 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.
CAUTION!
Do not connect jumper cable to any of the
fuses on the positive battery terminal. The
resulting electrical current will blow the fuse.
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.
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.
