Checking Oil Level — Gasoline Engine
To assure proper lubrication of your vehicle’s
engine, 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 five
minutes after a fully warmed up engine is
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
one quart 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.
Checking Oil Level — 3.0 Diesel Engine
To assure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level
is before starting the engine after it has been
parked overnight. When checking oil after
operating the engine, first ensure the engine
is at full operating temperature, then wait for
five minutes after engine shutdown to check
the oil.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Add oil only when the level on
the dipstick is below the “MIN” mark. The
total capacity from the MIN mark to the MAX
mark is 1 qt (1 L).
CAUTION!
Overfilling or underfilling the crankcase
will cause oil aeration or loss of oil pres-
sure. This could damage your engine.NOTE:
It is possible for your oil level to be slightly
higher than a previous check. This would be
due to diesel fuel that may temporarily be in
the crankcase due to operation of the diesel
particulate filter regeneration strategy. This
fuel will evaporate out under normal opera-
tion.
Never operate the engine with oil level below
the “MIN” mark or above the upper “MAX”
mark.
Adding Washer Fluid
The instrument cluster display will indicate
when the washer fluid level is low. When the
sensor detects a low fluid level, the wind-
shield will light on the vehicle graphic outline
and the “WASHER FLUID LOW” message
will be displayed.
The fluid reservoir for the windshield washers
and the rear window washer is shared. The
fluid reservoir is located in the engine com-
partment, be sure to check the fluid level at
regular intervals. Fill the reservoir with wind-
shield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reser-
