2014 JEEP WRANGLER UNLIMITED engine

Once the engine is started, remove the jumper cables in the reverse sequence:
• Disconnect the negative (-) jumper cable from the engine ground of the vehicle
with the discharged battery.
• Disconnect the negative end (-) of the jumper cable from the negative (-) post of
the booster battery.
• Disconnect the opposite end of the positive (+) jumper cable from the positive (+)
post of the booster battery.
• 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 inspected at your authorized dealer.
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.
• Failure to follow these procedures could result in damage to the charging
system of the booster vehicle or the discharged vehicle.
• Accessories that can be 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, the vehicle’s battery discharges suffi-
ciently to degrade battery life and/or prevent the engine from starting.
WARNING!• When temperatures are below the freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump-starting because the battery could rupture or
explode and cause personal injury. Battery temperature must be brought above the
freezing point before attempting a jump-start.
• Take care to avoid the radiator cooling fan whenever 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 watch bands or bracelets, that might make an
inadvertent electrical contact. You could be severely 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.
• Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property damage
due to battery explosion.
• 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.WHAT TO DO IN EMERGENCIES

EMERGENCY TOW HOOKS • If your vehicle is equipped with tow hooks, they are mounted in the front and the rear.
NOTE:
For off-road recovery, it is recommended to use both of the front tow hooks to
minimize the risk of damage to the vehicle.
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.
WARNING!• Chains are not recommended for freeing a stuck vehicle. Chains may break,
causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become
disengaged, causing serious injury.
SHIFT LEVER OVERRIDE • If a malfunction occurs and the shift
lever cannot be moved out of the PARK
position, you can use the following
procedure to temporarily move the
shift lever:
• To access the shift lever override,
remove the override cover located on
the shift lever bezel, next to the shift
lever.
• Firmly set the parking brake.
• Turn the ignition switch to the ACC
or ON position without starting the
engine.
• Press and maintain firm pressure on
the brake pedal.
• Using a screwdriver or similar tool, press and hold the override tab through the
access port on the center console.
• Move the shift lever into the NEUTRAL position.
• The vehicle may then be started in NEUTRAL.
• Reinstall the override cover.WHAT TO DO IN EMERGENCIES
109

TOWING A DISABLED VEHICLE • The manufacturer requires towing your vehicle with all four wheels OFF the ground
using a flatbed.
CAUTION!Towing this vehicle using any other method could result in extensive damage to the
transfer case and/or transmission.
FREEING A STUCK VEHICLE • If your vehicle becomes stuck in mud, sand or snow, it can often be moved by a
rocking motion. Turn your steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE/1st gear and REVERSE.
Using minimal accelerator pedal pressure to maintain the rocking motion, without
spinning the wheels, is most effective.
NOTE:
If your vehicle is equipped with Traction Control or Electronic Stability Control (ESC),
turn the system OFF before attempting to “rock” the vehicle.
CAUTION!• Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during prolonged efforts to free
a stuck vehicle.
• When “rocking” a stuck vehicle by moving between DRIVE/1st gear and
REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
WARNING!Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.WHAT TO DO IN EMERGENCIES

CAUTION!• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products.
Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
E85 FLEXIBLE FUEL — 3.6L ENGINE ONLY Refer to your Owner's Manual on the DVD for further details.
CAUTION!Only vehicles with the E-85 fuel filler door label or a yellow gas cap can operate

MAINTENANCE SCHEDULE Your vehicle is equipped with an automatic oil change indicator system. The oil change
indicator system will remind you that it is time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
and E85 fuel usage will influence when the “Change Oil” or “Oil Change Required”
message is displayed. Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since last reset. Have your
vehicle serviced as soon as possible, within the next 500 miles (805 km).MAINTAINING YOUR VEHICLE
