2012 JEEP WRANGLER ignition

- Charging System Light
• This light shows the status of the electrical charging system. If the
charging system light remains on, it means that the vehicle is
experiencing a problem with the charging system.
• We recommend you do not continue driving if the charging system light
is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on while
driving, stop the vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will
occur. Have the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving,
we recommend you drive to the nearest service center and have the
vehicle serviced immediately.
- Electronic Throttle Control (ETC) Light
• This light informs you of a problem with the Electronic Throttle Control
(ETC) system.
• If a problem is detected, the light will come on while the engine is
running. Cycle the ignition when the vehicle has completely stopped and
the shift lever is placed in the PARK position; the light should turn off.
• If the light remains lit with the engine running, your vehicle will usually be
drivable; however, see an authorized service center immediately. If the
light is flashing when the engine is running, immediate service is required
and you may experience reduced performance, an elevated/rough idle or
engine stall and your vehicle may require towing.
- Air Bag Warning Light
• If the light is not on during starting, stays on, or turns on while driving,
have the vehicle serviced by an authorized service center immediately.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as gASCAP) appears, tighten the gas cap
until a “clicking” sound is heard.
• Press the odometer reset button to turn the message off.
• If the message continues to appear for more than three days after
tightening the gas cap, see your authorized service center.
Oil Change IndicatorMessage

Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
HOTOIL – Transmission Temperature Warning Message
• The HOTOIL cluster message will appear in the odometer accompanied
with a chime to indicate that there is excessive transmission fluid
temperature that might occur with severe usage such as trailer towing.
• It may also occur when operating the vehicle in a high torque converter
slip condition, such as 4-wheel-drive operation (e.g., snow plowing,
off-road operation).
• If this HOTOIL message turns on, stop the vehicle and run the engine at
idle or faster, with the transmission in NEUTRAL until the message turns
off.
CAUTION!
Continuous driving with the Transmission Temperature HOTOIL
Warning message illuminated will eventually cause severe
transmission damage and transmission failure.
WARNING!
Continued operation with the Transmission Temperature HOTOIL
Warning message illuminated could cause the fluid to boil over, come
into contact with the hot engine or exhaust components causing a fire
that may result in personal injury.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for
overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but
do not increase engine idle speed.
NOTE:There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to
the engine cooling system and turning the A/C off can help remove this
heat.
• You can also turn the temperature control to maximum heat, the mode
control to floor and the blower control to high. This allows the heater core
to act as a supplement to the radiator and aids in removing heat from the
engine cooling system.

Preparations For Jacking
1. Park on a firm, level surface. Avoid ice or slippery areas.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Shift the automatic transmission into PARK, or a manual transmission
into REVERSE.
5. Turn the ignition to LOCK.
Block both the front and rear of the
wheel diagonally opposite of the
jacking position. For example, if
changing the right front tire, block the
left rear wheel.
NOTE:Passengers should not remain
in the vehicle when the vehicle is
being jacked.
Jacking Instructions
1. Remove the spare tire, jack and
tools from the stored location.
2. Loosen (but do not remove) the
wheel lug nuts by turning them to
the left one turn while the wheel
is still on the ground.
3. Assemble the jack and jacking
tools. Connect the jack handle
driver to the extension, then to
the lug wrench.

WARNING!(Continued)
• To assure that spare tires, flat or inflated, are securely stowed,
spares must be stowed with the valve stem facing the ground.
• Raising the vehicle higher than necessary can make the vehicle less
stable and cause a collision. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to remove the tire.
• To avoid the risk of forcing the vehicle off the jack, do not tighten
the wheel nuts fully until the vehicle has been lowered.
• A loose tire or jack, thrown forward in a collision or hard stop, could
endanger the occupants of the vehicle. Always stow thejack parts
and the spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten
the lug nuts fully until the vehicle is lowered to the ground.
JUMP-STARTING
• 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.
Preparations for Jump-Start
• The battery in your vehicle is located in the right rear of the engine
compartment.
• Set the parking brake, shift the automatic transmission into PARK and
turn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• 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.
Jump-Starting Procedure
• Connect the positive (+) end of the jumper cable to the positive (+) post
of the discharged vehicle.

WARNING!(Continued)
• 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 sparksaway 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.
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.

• The vehicle may then be started in NEUTRAL.
• Reinstall the override cover.
TOWING A DISABLED VEHICLE
• The manufacturer requires towing your vehicle with all four wheelsOFF
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.
