When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, add at least one quart/liter of the
recommended oil. This section explains what kind of oil
to use. For engine oil crankcase capacity, see
Capacities and Specifications on page 5-130.
Notice:Do not add too much oil. If the engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, the engine could be damaged.SeeEngine Compartment
Overview on page 5-14for
the location of the engine
oil ll cap.
Be sure to add enough oil to put the level somewhere in
the proper operating range. Push the dipstick all the
way back in when you are through.

(l)Extreme Duty Service: Change transfer case fluid if
the vehicle is mainly driven off-road in four-wheel
drive, or is used for heavy trailer towing. Farming,
mining, forestry, and Department of Natural Resources
(DNR) vehicles meet this definition.
(m)During any maintenance, if a power washer is used
to clean mud and dirt from the underbody, care should be
taken to not directly spray the transfer case output seals.
High pressure water can overcome the seals and
contaminate the transfer case fluid. Contaminated fluid
will decrease the life of the transfer case and should be
replaced.
(n)Vehicles with diesel engine or with GVWR above
10,000 lbs (4 536 kg) only: Inspect shields for damage or
looseness. Adjust or replace as required. This is a
Noise Emission Control Service. Applicable to vehicles
sold in the United States and recommended for
vehicles sold in Canada.
(p)If you drive regularly under dusty conditions, inspect
the filter or change indicator (if equipped) at each
engine oil change.
(q)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.Owner Checks and Services
These owner checks and services should be performed
at the intervals speci ed to help ensure the safety,
dependability, and emission control performance of your
vehicle. Your dealer/retailer can assist you with these
checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-15.
At the First 100, 1,000 and 6,000
Miles (160, 1 600 and 10 000 km)
For vehicles with dual wheels, check dual wheel
nut torque. For proper torque, seeCapacities and
Specifications on page 5-130.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel fill.
