JEEP GRAND CHEROKEE 2010 WK / 3.G Workshop Manual

Jack Location
• The scissor-type jack and tire changing tools are located in the passenger sidecompartment, behind the second row seat.
Spare Tire Stowage
• To remove or stow the spare, use the jack handle to rotate the “spare tire drive” nut whichis located under a plastic cover under the cargo load floor, just inside the liftgate opening.
• Lower the spare tire by turning the drive nut counterclockwise with the jack-handle assembly until the spare tire is on the ground with enough cable slack to allow you to
pull the spare tire out from underneath the vehicle.
• When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel.
Preparations For Jacking
• Park on a firm, level surface. Avoid ice or slippery areas.
• Set the parking brake and shift the automatic transmission into PARK.
• Turn the ignition to LOCK and turn on the Hazard Warning flasher.

WHAT TO DO IN EMERGENCIES

• Block both the front and rear of the wheeldiagonally 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 And Tire Changing Instructions
WARNING!
Carefully follow these tire changing procedures to help prevent personal injury or
damage to your vehicle: Always park on a firm, level surface as far from the edge of
the roadway as possible before raising the vehicle.
• Remove the spare tire, jack and tools from their stored location.
• 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.
• Assemble the jack and jacking tools. Connect the jack handle driver to the extension, then to the lug wrench.
• Place the jack: • For front wheels, place it under the front lower control arm.

• For rear wheels, place it under the axle near the wheel to be changed.
51
WHAT TO DO IN EMERGENCIES

• Turn the jack screw clockwise to firmly engage the jack saddle with the lift area of thesill flange.
• Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire.
WARNING!
Raising the vehicle higher than necessary can make the vehicle less stable and
cause an accident. It could slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
• Remove the lug nuts, wheel cover (if equipped) and wheel.
• Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the wheel. Do NOT attempt to install a center cap or wheel cover on the
compact spare. Lightly tighten the lug nuts clockwise. To avoid the risk of forcing the
vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered.
• Lower the vehicle by turning the jack screw to the left, and remove the jack and wheel blocks.
• Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each one has been tightened twice. The correct wheel nut
tightness is 95 ft lbs (130 N•m). If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer or at a service station.
WARNING!
A loose tire or jack, thrown forward in a collision or hard stop, could endanger the
occupants of the vehicle. Always stow the jack parts and the spare tire in the places
provided.
• Secure the tire, jack, and tools in their proper locations.
NOTE: Tire should be stowed with the “beauty” side up. Storing the tire upside down may
result in scratching or damage to the wheel face. Continue winching up the tire until you
hear the winch “ratchet” three times.

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.
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.
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
freezing point before attempting a jump-start.
53
WHAT TO DO IN EMERGENCIES

Preparations for Jump-Start
• The battery in your vehicle is located in the front of the engine compartment, behind theleft headlight assembly.
WARNING!
• 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 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.
• 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
54

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.
CAUTION!
Failure to follow these procedures could result in damage to the charging system of
the booster vehicle or 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!
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.
55
WHAT TO DO IN EMERGENCIES

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.
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.

WHAT TO DO IN EMERGENCIES

EVENT DATA RECORDER (EDR)
• This vehicle is equipped with an Event Data Recorder (EDR). The main purpose of an EDRis 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.
