Jump-Starting - Jeep Cherokee 2009 Operating Information Manual

Rear Jacking Location
5. Raise the vehicle by turning the jack screw to
the right. Raise the vehicle only until the tire just
clears the surface and enough clearance is ob-
tained to install the spare tire. Minimum tire lift
provides maximum stability.
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.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and
install lug nuts with the cone-shaped end toward
the wheel. Lightly tighten the nuts. To avoid the
risk of forcing the vehicle off the jack, do not
tighten the nuts fully until the vehicle has been
lowered.
8. Lower the vehicle by turning the jack screw to
the left, and remove the jack and wheel blocks.
9. Finish tightening the lug nuts. Push down on
the wrench while tightening for increased lever-
age. Alternate nuts until each nut has been tight-
ened twice. Correct wheel nut tightness is 95 ft lb
(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.
10. Lower the jack to it's fully closed position.
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.
11. Secure the tire, jack, and tools in their proper
locations.
JUMP–STARTING
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
hurt by the fan.
• Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto-
matic transmission cannot be started this way.
Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite
and damage the converter and vehicle. If the
vehicle has a discharged battery, booster
cables may be used to obtain a start from
another vehicle. This type of start can be
dangerous if done improperly, so follow this
procedure carefully.
• Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin, or
clothing. Don't lean over battery when attach-
ing clamps or allow the clamps to touch each
other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large
quantities of water.
• A battery generates hydrogen gas, which is
flammable and explosive. Keep flame or spark
away from the vent holes.
• Do not use a booster battery or any other booster
source with an output that exceeds 12 volts.
