been submerged in water. Water can enter through the axle
vent hole and contaminate the lubricant.

COMMAND-TRAC (4WD)

CAUTION: NEVER operate a Command-Trac vehicle in 4WD on dry,
hard-surfaced roads for a sustained period. Use 4L only
when needed for added pulling power. Operating vehicle in
4WD mode on such roads will cause stress and possible
damage to components, as well as make shifting difficult.
To reduce shifting effort, drive vehicle in Reverse for a
few feet, or drive off hard-surfaced road momentarily to
allow tire slippage.

FRONT AND REAR DIFFERENTIALS (4WD)

CAUTION: DO NOT use water, steam, kerosene or gasoline for flushing
a differential. ONLY use a flushing oil.

TRAC-LOK DIFFERENTIALS (4WD)

CAUTION: DO NOT flush a rear axle Trac-Lok differential. Trac-Lok
differentials may be cleaned only by disassembling the
unit and wiping the components with clean, lint-free cloth.
CAUTION: NEVER attempt to engage Low range when vehicle is moving
faster than 2-3 MPH, as transfer case damage may result.

OIL FILTER

CAUTION: Verify that proper Oil Filter is being used. Filters with
metric threads (M20 x 1.5) must be used with some engines.
Other engines use SAE type (3/4" x 16) threads, and must
use an oil filter with these threads. Possible engine damage
can occur with improper oil filter.
WHEEL & TIRE WARNINGS
CAUTION: Replacing original tires with different size tires may
result in false speedometer and odometer indications. Check
with dealer before using different size tires on vehicle.
CAUTION: Ensure all 4 wheels on vehicle have same tire size, type
and circumference in order to provide proper vehicle
handling. DO NOT mix radial-ply with bias-ply or
bias-belted tires. On 4WD vehicles, if tire size, type and
circumference on all 4 wheels are not the same, gear
shifting will be adversely affected and can damage transfer
case.
CAUTION: Temporary-use spare tires are for emergency use only. DO
NOT drive vehicle faster than 50 MPH or more than 100 miles
when using spare tire. DO NOT operate vehicle in 4WD mode
when using spare tire, as damage to transfer case can
result. Temporary-use spare tires have a total tread life
of 3,000 miles.
