2006 JEEP WRANGLER oil viscosity

•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
•If the shoulder belt contacts the child’s face or neck,
move the child closer to the center of the vehicle.
Never allow a child to put the shoulder belt under an
arm or behind their back.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

13. Oil Pressure Gauge Indicates engine oil pressure. This gauge does not
indicate oil level, and pressure varies with engine
speed, temperature and oil viscosity. Consistent lower
readings indicate possible malfunction. Seek authorized
service.
14. Coolant Temperature Gauge Indicates engine coolant temperature. The red
zone to the far right indicates possible overheat-
ing. Seek authorized service immediately if the
gauge operates in the red zone. In U.S. vehicles, tempera-
ture is indicated in degrees fahrenheit; in Canadian
vehicles in degrees centigrade.
15. Airbag Warning Light This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If
the light does not come on for 6 to 8 seconds, stays on or comes on while driving, have the airbag
system checked by an authorized dealer.
16. Check Gauges Warning Light
This light monitors the engine coolant tem-
perature, engine oil pressure, and voltage
gauges. If it detects an extreme condition a
chime will sound and the light will come on. If the light
comes on, check the operation of these gauges for a
malfunction condition.
17. Malfunction Indicator Light This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine, and
automatic transmission control systems. The light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the key from OFF to ON, have the condition
checked promptly.

Engine Oil Viscosity (2.4L Engines)
SAE 5W-30 engine oil is recommended for all operating
temperatures. This engine oil improves low tempera-
ture starting and vehicle fuel economy. Your engine oil
filler cap shows the recommended engine oil viscosity
for your vehicle.
Engine Oil Viscosity (4.0L Engines)
SAE 10W-30 engine oil is recommended for all operat-
ing temperatures. This engine oil improves low tem-
perature starting and vehicle fuel economy. Your engine
oil filler cap shows the recommended engine oil vis-
cosity for your vehicle.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
authorized dealer, service station, or governmental
agency for advice on how and where used oil can be
safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
