2011 JEEP WRANGLER engine

• Please note that the TPMS is not a substitute for proper tire maintenance, and it isthe driver’s responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS low tire pressure telltale.
• Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not use tire sealant from a
can, or balance beads if your vehicle is equipped with a TPMS, as damage to the
sensors may result.

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 bytaking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into 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 Fan 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.
• 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.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.

JUMP-STARTING
• If your vehicle has a discharged battery it can be jump-started using a set of jumpercables 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 thedischarged vehicle.
• Connect the opposite end of the positive (+) jumper cable to the positive (+) post of the booster battery.
• Connect the negative end (-) of the jumper cable to the negative (-) post of the booster battery.
• 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.
• 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

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.
• Reinstall the air intake duct.
• 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 asystem 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 will discharge
sufficiently to degrade battery life and/or prevent the engine from starting.
WARNING!
• When temperatures are below the freezing point, electrolyte in a dischargedbattery may freeze. Do not attempt jump-starting because the battery could
rupture or explode and cause personal injury. Battery temperature must be
brought above 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.
