2012 JEEP WRANGLER cooling

- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull
over and stop the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage
will occur. Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be
badly burned by steam or boiling coolant. You may want to call an
authorized service center for service if your vehicle overheats.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system
malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the
brake system may have failed. It will take longer to stop the vehicle.
You could have a collision. Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality,
etc., may illuminate the MIL after engine start. The vehicle should be
serviced if the light stays on through several typical driving cycles. In
most situations, the vehicle will drive normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may
exist that could lead to immediate loss of power or severe catalytic
converter damage. We recommend you do not operate the vehicle. Have
the vehicle serviced immediately.
- Electronic Stability Control OFF Warning Light
• If the ESC OFF warning light comes on continuously with the engine
running, a malfunction has been detected.
• If this light remains on after several ignition cycles, and the vehicle has
been driven several miles (kilometers) at speeds greater than 30 mph
(48 km/h), we recommend you drive to the nearest service center and
have the vehicle serviced immediately.

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.

CAUTION!
Driving with a hot cooling system could damage your vehicle. If the
temperature gauge reads 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
turn the engine off immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze)
or steam from your radiator. If you see or hear steam coming from
under the hood, do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure cap when the
radiator or coolant bottle is hot.
JACKING AND TIRE CHANGING
Jack Location
• The jack and lug wrench are located in the rear storage compartment.
NOTE:Turn the black plastic wing nut counter clockwise to loosen the jack
from the storage bin.
Spare Tire Stowage
• To remove the spare tire from the carrier, remove the tire cover, if
equipped, and remove the lug nuts with the lug wrench turning them
counterclockwise.
NOTE:If you have added aftermarket accessories to the spare tire mounted
carrier, it cannot exceed a gross weight of 70 lbs (32 kg) including the
weight of the spare tire.

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.
