374 SERVICING AND MAINTENANCE

Checking Oil Level

To ensure proper lubrication of your vehicle's engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding 1 quart (0.95 liters) of oil when the reading is at the
bottom of the SAFE zone will result in a reading at the top
of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.

Adding Washer Fluid

The fluid reservoir for the windshield washers and the rear
window washer (if equipped) is shared. The fluid reservoir
is located in the engine compartment. Be sure to check the
fluid level at regular intervals. Fill the reservoir with
windshield washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and wipe clean
the wiper blades; this will help blade performance.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Commercial windshield washer solvents are flam-
mable. They could ignite and burn you. Care must be
exercised when filling or working around the washer
solution.

Maintenance-Free Battery

Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
WARNING!
• Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
