engine oil JEEP PATRIOT 2007 1.G Owners Manual

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.

Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check wheel nuts for tightness, and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected or fuel, power steering fluid, trans-
mission fluid or brake fluid leaks are suspected, the cause
should be located and corrected immediately.

4. Oil Pressure Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on during starting, have the system checked by
an authorized dealer.
If the light comes on and remains on while driving, stop
the vehicle and shut off the engine. DO NOT OPERATE
THE VEHICLE UNTIL THE CAUSE IS CORRECTED.
The light does not show the quantity of oil in the engine.
This can be determined using the procedure shown in
Section 7.
5. Low Fuel Light
When the fuel level drops to 2 gallons, the fuel
symbol will light and a single chime will sound.6. Speedometer
Indicates vehicle speed.
7. Airbag Light
The light comes on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light does not
come on during starting, stays on, or comes on
while driving, have the system checked by an authorized
dealer.
8. Turn Signal Indicators
The arrows will flash in unison with the exterior
turn signal, when using the turn signal lever.
9. High Beam Indicator
This light shows that the headlights are on high
beam. Push the turn signal lever away from the
steering wheel to switch the headlights from high or low
beam.

NOTE:Continuous use of the recirculate mode may
make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the Recirculate
position will cause windows to fog on the inside because
of moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.
NOTE:Recirculation Mode will not operate in floor, mix
or defrost modes.
Air Filtration System ± If Equipped
An air filter is included in the optional Security Group.
Filter media includes a particle filtration layer and acharcoal layer. The filter will reduce, but not eliminate,
diesel and agricultural smells. The filter acts only on air
coming from outside the vehicle; it does not filter air
inside the passenger compartment. See the maintenance
schedule for the filter change interval. The air filter
change interval coincides with engine oil and filter
change intervals. As with oil changes, the interval is
shorter for heavy duty service or dusty conditions. See
your authorized dealer for service.

the possibilities of a down hill slide or roll over. Make
sure the surface has good traction with firm and stable
soils. If possible transverse the incline at an angle
heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll
over, which may result in severe injury.
²If You Stall Or Begin To Lose Headway± If you stall
or begin to lose headway while climbing a steep hill,
allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift to R
(Reverse). Back slowly down the hill allowing engine
and hill descent braking to control the descent and
apply your brakes if necessary, but do not allow the
tires to lock
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle, which may result in
severe injury. Always back carefully straight down a
hill in R (Reverse) gear. Never back down a hill in N
(Neutral) using only the vehicle brakes. Never drive
diagonally across a hill, always drive straight up or
down
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only
be attempted when necessary, in a safe responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly and
262 STARTING AND OPERATING

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 Section 7, Maintenance, 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!
²Being 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.
²The 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.

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop.The best time to check the engine oil level is about 5
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Engine Oil Dipstick
MAINTAINING YOUR VEHICLE 347
7

Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone that says SAFE or a cross-
hatch zone that says MIN at the low end of the range and
MAX at the high end of the range. Adding one quart of
oil when the reading is at the low end of the indicated
range will result in the oil level at the full end of the
indicator range.
CAUTION!
Do not overfill the engine. Overfilling the engine as
indicated by the range markings, as described above,
on the engine oil dipstick will cause oil aeration,
which can lead to loss of oil pressure and an increase
in oil temperature. This could damage your engine.
Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to decide if any apply to you.
²Day and night temperatures are below 32ÉF (0ÉC).
²Stop and Go driving.
²Extensive engine idling.
²Driving in dusty conditions.
²Short trips of less than 10 miles (16 km).
²More than 50% of your driving is at sustained high
speeds during hot weather, above 90ÉF (32ÉC).
²Trailer towing.
²Taxi, Police or delivery service (commercial service).
²Off-Road or desert operation.
