2013 JEEP WRANGLER UNLIMITED jump cable

WARNING! (Continued)• 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 dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
Without Tip Start – Manual Transmission Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while cranking the
engine. This should clear any excess fuel in case the
engine is flooded. CAUTION!To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15-second
periods of cranking with the accelerator pedal held to the
floor, repeat the “Normal Starting” or “Extreme Cold
Weather” procedures.412 STARTING AND OPERATING

JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack
follow the manufacturer ’s operating instructions and
precautions. CAUTION!Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.548 WHAT TO DO IN EMERGENCIES

1. Set the parking brake, shift the automatic transmission
into PARK (manual transmission in NEUTRAL) and
turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.
3. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result. Jump-Starting Procedure
WARNING!Failure to follow this procedure could result in per-
sonal injury or property damage due to battery ex-
plosion.
CAUTION!Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
1. Connect the positive (+) end of the jumper cable to the
positive (+) post of the discharged vehicle.
2. Connect the opposite end of the positive (+) jumper
cable to the positive (+) post of the booster battery.550 WHAT TO DO IN EMERGENCIES

3. Connect the negative end (-) of the jumper cable to the
negative (-) post of the booster battery.
4. Connect the opposite end of the negative (-) jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!Do not connect the cable to the negative post (-) of the
discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury.
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. Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-) jumper cable from the
engine ground of the vehicle with the discharged
battery.
7. Disconnect the negative end (-) of the jumper cable
from the negative (-) post of the booster battery.
8. Disconnect the opposite end of the positive (+) jumper
cable from the positive (+) post of the booster battery.
9. Disconnect the positive (+) end of the jumper cable
from the positive (+) post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.

Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR  engine air
cleaner filters are a high quality filter and are recom-
mended.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required. WARNING!• Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water. Refer to
“Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.
• Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.
• Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.570 MAINTAINING YOUR VEHICLE
