2009 JEEP PATRIOT engine

NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes 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.CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H”,
pull over when safe and stop the vehicle with the
engine at idle. Turn the air conditioner off and wait
until the pointer drops back into the normal range.
After appropriate action has been taken, if the
pointer remains on the “H”, turn the engine OFF
immediately and call for service.

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 a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintenance”, Section 7 of
this manual. Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.
If this happens, the transmission overheat in-
dicator light will come on, and the vehicle will
slow slightly until the automatic transaxle
cools down enough to allow a return to therequested speed. If the high speed is maintained, the
overheating will reoccur, as before, in a cyclic fashion.
JACKING AND TIRE CHANGING
WARNING!
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you
need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
352 WHAT TO DO IN EMERGENCIES

5. Turn on the Hazard Warning flasher.
6. Block both the front and rear of the
wheel diagonally opposite the jacking
position. For example, if changing the
right front tire, block the left rear
wheel.
NOTE:Passengers should not remain in the vehicle
while the vehicle is being jacked.
Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:

WARNING! (Continued)
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
•Never start or run the engine with the vehicle on a
jack.
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.

JUMP-STARTING PROCEDURES
WARNING!
•Take care to avoid the radiator cooling fan when-
ever 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 automatic
transaxle cannot be started this way and may be
damaged. Unburned fuel could enter the catalytic
converter 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 im-
properly, so follow this procedure carefully.
(Continued)
WARNING! (Continued)
•Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make
an inadvertent electrical contact. You could be
seriously injured.
NOTE: Disconnecting the battery with the ignition in
the ON position will cause vehicles with an automatic
transaxle (CVT2) to go into “default mode” and turn on
the Malfunction Indicator Light (MIL). See your autho-
rized dealer to correct this condition.
1. When boosting from a battery in another vehicle, park
that vehicle within booster cable reach but without
letting the vehicles touch. Set the parking brake, place the
automatic transmission in PARK (the manual transmis-
sion in NEUTRAL) and turn the ignition to OFF for both
vehicles.
358 WHAT TO DO IN EMERGENCIES

2. Turn off the heater, radio and all unnecessary electrical
loads.
3. Using the two finger screws on the cover, remove the
air intake duct covering the battery.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the jumper cable to the positive terminal of the dis-
charged battery.
WARNING!
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don’t lean over the battery when attaching the
clamps or allow the clamps to touch each other. If
acid splashes in your eyes or on your skin, flush
the contaminated area immediately with large
quantities of water.
(Continued)
WARNING! (Continued)
•A battery generates hydrogen gas which is flam-
mable 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.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the negative terminal of
the discharged battery. Make sure you have a good
contact.
6. If the vehicle is equipped with a Sentry KeyImmo-
bilizer, turn the ignition switch to the ON position for
three seconds before moving the ignition switch to the
START position.
7. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.

8. When removing the jumper cables, reverse the se-
quence exactly. Be careful of the moving belts and fan.
FREEING A STUCK VEHICLE
NOTE:If your vehicle is equipped with Traction Con-
trol or ESP, turn the system OFF before attempting to
“rock” the vehicle.
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between RE-
VERSE and 1st gear. Usually the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause axle, tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck.
And don’t let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transaxle overheating and failure. It can
also damage the tires. Do not spin the wheels above
30 mph (48 km/h). Do not spin the wheels continu-
ously for more than 30 seconds.
