2012 JEEP LIBERTY tire pressure

FREEING A STUCK 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 DRIVE
and REVERSE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without spinning the
wheels, is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.NOTE:
If your vehicle is equipped with Traction Con-
trol or Electronic Stability Control (ESC), turn the system
OFF before attempting to “rock” the vehicle.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
448 WHAT TO DO IN EMERGENCIES

Cooling System
WARNING!
•You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, do not open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed, and refilled with fresh coolant. Check the front
of the A/C condenser (if equipped) or radiator for anyaccumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the A/C condenser (if equipped) or the back of the
radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery bottle and radiator. Inspect the
entire system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.

MAINTAINING YOUR VEHICLE 495

Once A Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of the coolant reservoir and the
brake master cylinder, add as needed.
•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
•Failure to perform the required maintenance items
may result in damage to the vehicle.
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case. Tire rotation
schedule should be followed to balance tire wear.
