2007 JEEP WRANGLER ignition

JUMP STARTING
If the vehicle has a discharged battery, booster cables may
be used to obtain a start from a booster battery or the
battery in another vehicle. This type of start can be danger-
ous if done improperly, so follow this procedure carefully.
WARNING!
Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don’t lean
over battery when attaching clamps or allow the clamps
to touch each other. If acid splashes in eyes or on skin,
flush contaminated area immediately with large quan-
tities of water.
A battery generates hydrogen gas which is flammable
and explosive. Keep flame or spark away from the vent
holes.
Do not use a booster battery or any other booster source
that has a greater than 12 volt system, i.e. Do not use a 24
volt power source.
1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.
2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the automatic transmission in P
(Park), or the manual transmission in N (Neutral), and
turn the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
356 WHAT TO DO IN EMERGENCIES

Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off theignition key or start the engine. This means that your
vehicle’s OBD system isnot readyand you shouldnot
proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or start
the engine. This means that your vehicle’s OBD system
isreadyand you can proceed to the I/M station.
If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing.
•Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
•Do not allow vehicle to run out of fuel.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

CAUTION!
•When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in a electrical system
failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
•Store the removed IOD fuse in the Power Distribution
Center location #11 labeled “IOD Storage.”
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
