Four- Wheel Drive
If your vehicle has four-wheel drive, you can send your engine’s driving
power to all four wheels for extra traction.
To get the most satisfaction out
of four-wheel drive, you must be familiar with its operation. Read the part
that follows before using four-wheel drive. You should use 2-WHEEL
HIGH (2H) for most normal driving conditions.
NOTICE:
Driving in the 4-WHEEL HIGH (4H) or &WHEEL LOW (4L)
positions for a long time on dry or wet pavement could shorten
the life of your vehicle’s drivetrain.
I NOTICE:
Changing your vehicle’s body height can damage your vehicle’s
suspension, drivetrain, or other vehicle components.
It may also
affect the way your vehicle handles, and the function of your
vehicle’s safety features. Do not change your vehicle’s height
from the original design specifications.
Transfer Case
The transfer case shift
lever is on the floor to
the right of the driver.
Use this lever to shift
into and out
of
four-wheel drive.
An indicator near the lever shows you the transfer case settings.

Loading Your Vehicle
I
PSI/KPA (COLD)
~ SEE OWNER'S MANUAL FOR ADDITIONAL INFORMATION
The CertificatiodTire label is found on the rear edge of the driver's door.
The label shows the size
of your original tires and the inflation pressures
needed to obtain the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The Certificatiodl'ire label
also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR). To find
out
the actual loads on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help you with this. Be sure
to spread out your load equally on both sides
of the centerline.
Never exceed the GVWR
for your vehicle, or the GAWR for either the front
or rear axle.
And, if you do have a heavy load, you should spread it out.
.Using heavier suspension components to get added durability might not
change your weight ratings. Ask your dealer to help you load your vehicle
the right way.
If your vehicle is equipped for front-end equipment (a snow plow, for
example), the front suspension may have been adjusted (raised) to level the
vehicle when the equipment was installed. If the front suspension was
adjusted, you must re-adjust the front suspension after the equipment is
removed to avoid possible front suspension damage. Adjust the front
suspension
to original design specifications for your particular model.

You should keep a record with all parts receipts and list the mileage and the
date
of any servi-work you perform. See “Maintenance Record” in the
Index.
NOTICE:
If you try to do your own service work without knowing enough
about it, your vehicle could be damaged.
Maintenance Schedule
Section 7 of this manual, “Scheduled Maintenance Services”, explains the
maintenance your
new vehicle needs, and when it should be done. It also
has a form that
you can use to record the maintenance work done on your
vehicle. Be sure
to read this information.
Fuel (Gasoline Engine)
If your vehicle has a diesel engine, see “Diesel Fuel Requirements and Fuel
System”
in this Section. For vehicles with gasoline engines, please read this.
Use regular unleaded gasoline rated at 87 octane or higher. It should meet
specifications ASTM D48 14
in the United States and CGSB 3.5-92 in
Canada. These fuels should have the proper additives, so you should not
have to add anything to the fuel.
In
the United States and Canada, it’s easy to be sure you get the right kind
of gasoline (unleaded). You’ll see UNLEADED right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.

Turn off the engine
and give the oil
a few
minutes
to drain back
into the oil pan.
If you
don’t, the oil dipstick
might not show the
actual level.
To Check Engine Oil
Pull out the dipstick and clean it with a paper towel or cloth, then push it
back in all the way. Remove it again, keeping the tip down.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need to add some oil. But
you must use the right kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the upper mark that shows the proper
operating range,
your engine could be damaged.
