2007 JEEP WRANGLER battery

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord. The engine block
heater cord is found under the hood bundled in front of
the battery tray.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
MANUAL TRANSMISSION
6-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.

4. Start engine.
5. Shift automatic transmission into D (Drive) or manual
transmission into gear.
6. Release brake pedal and ensure that there is no vehicle
movement.
7. Shut the engine off and place the ignition key into the
ACC position.
8. Shift automatic transmission into P (Park).

10. Attach vehicle to the tow vehicle with tow bar.
11. Release parking brake.
12. Disconnect the negative battery cable, and secure it
away from the negative battery post.CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into P (Park) with the transfer case
in N (Neutral) and the engine running. With the
transfer case in N (Neutral) ensure that the engine is
off prior to shifting the transmission into P (Park)
(refer to steps 7 – 8 above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift automatic transmission into N (Neutral) or de-
press clutch pedal on manual transmission.
2. Shift transfer case lever into desired position.

HAZARD WARNING FLASHERS
Your vehicle’s hazard warning flasher is an emergency
warning system. When you activate it, all front and rear
directional signals will flash intermittently. Use it when
your vehicle is disabled on or near the road. It warns
other drivers to steer clear of you and your vehicle. This
is an emergency warning system, not to be used when the
vehicle is in motion.
To activate the warning flashers, press the button on the
lower switch bank (below the climate controls). To turn
the warning flashers off, press the button again.
NOTE:With extended use, the flasher may wear down
your battery.

350 WHAT TO DO IN EMERGENCIES

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

WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine of the
vehicle with the discharged battery. Make sure you have
a good contact on the engine.
WARNING!
•You should not try to start your vehicle by pushing
or towing.
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
•During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump start.

6. Start the engine in the vehicle which has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, they are
mounted in the front and the rear.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle. Tow straps are recommended
when towing the vehicle, chains may cause vehicle
damage.

Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A loose fuel filler cap message
will be displayed in the instrument cluster. Tighten the
gas cap until aclickingsound is heard. This is an
indication that the gas cap is properly tightened. Press
the odometer reset button to turn the message off. If the
problem persists, the message will appear the next time
the vehicle is started. This might indicate a damaged cap.
If the problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Light)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
