2015 JEEP CHEROKEE battery

3. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
4. Finish tightening the wheel bolts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern until
each wheel bolt has been tightened twice. Refer to
“Torque Specifications” in this section for the proper
lug bolt torque. If in doubt about the correct tightness,
have them checked with a torque wrench by your
authorized dealer or service station.
5. Lower the jack until it is free. Remove the wheel
chocks. Reassemble the lug wrench to the jack assem-
bly and stow it in the spare tire area. Secure the
assembly using the means provided. Release the park-
ing brake before driving the vehicle.
6. After 25 miles (40 km) check the wheel bolt torque
with a torque wrench to ensure that all wheel bolts are
properly seated against the wheel.
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.
640 WHAT TO DO IN EMERGENCIES

WARNING!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:The positive battery post is covered with a
protective cap. Lift up on the cap to gain access to the
positive battery post.

WHAT TO DO IN EMERGENCIES 641

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by
moving fan blades.
•Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
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 jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
642 WHAT TO DO IN EMERGENCIES

CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
Connecting The Jumper Cables
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.
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 jumper cable to the negative (-)
post of the discharged battery. The resulting electri-
cal spark could cause the battery to explode and
could result in personal 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.

WHAT TO DO IN EMERGENCIES 643

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 dis-
charged 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 in-
spected 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 phones, 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.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Press and hold the lock button on the shift
lever. Then shift back and forth between DRIVE and
REVERSE, while gently pressing the accelerator.

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Shift Lever Override” in this section
for instructions on shifting the transmission out of PARK
so that the vehicle can be moved.
