JEEP WRANGLER 2010 JK / 3.G Workshop Manual

WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can startanytime 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 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.
• 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 a 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 procedure could result in personal injury or property damage
due to battery explosion.
CAUTION!
Failure to follow these procedures could result in damage to the charging system of
the booster vehicle or the discharged vehicle.
• Connect the positive (+) end of the jumper cable to the positive (+) post of the discharged 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.

WHAT TO DO IN EMERGENCIES

WARNING!
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.
• 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.
• 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!
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.
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.
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 and chains may break, causing serious injury.
WHAT TO DO IN EMERGENCIES
50

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.
TOWING A DISABLED VEHICLE
• The manufacturer requires towing your vehicle with all four wheelsOFFthe ground
using a flatbed.
CAUTION!
Towing this vehicle using any other method could result in extensive damage to the
transfer case and/or transmission.
EVENT DATA RECORDER (EDR)
• This vehicle is equipped with an Event Data Recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment
or hitting a road obstacle, data that will assist in understanding how a vehicle's systems
performed. The EDR is designed to record data related to vehicle dynamics and safety
systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
• This data can help provide a better understanding of the circumstances in which a crash and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash
situation occurs; no data is recorded by the EDR under normal driving conditions and no
personal data (e.g., name, gender, age, and crash location) is recorded. However, other
parties, such as law enforcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a crash investigation.
• To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such
as law enforcement, that have the special equipment, can read the information if they
have access to the vehicle or the EDR.

WHAT TO DO IN EMERGENCIES

OPENING THE HOOD
• Release the two hood latches located on theleft and right side of the hood.
• Raise the hood and locate the safety latch, in the middle of the hood opening.
• Push the latch to the left side of the vehicle, to open the hood. You may have to push down
slightly on the hood before pushing the safety
latch.
• Insert the support rod into the slot on the hood.
• To close the hood, remove the support rod and place it in the retaining clip, then lower
the hood slowly.
• Secure both of the hood latches.
WARNING!
Be sure the hood is fully latched before driving your vehicle. If the hood is not fully
latched, it could open when the vehicle is in motion and block your vision. Failure to
follow this warning could result in serious injury or death.
