tire type JEEP WRANGLER UNLIMITED 2017 Owners Manual

wear and damage to the driveline components. Refer to
“Shifting Procedures” in this section for further informa-
tion on shifting into 4H or 4L.
The “4WD Indicator Light” (located in the instrument
cluster) alerts the driver that the vehicle is in four-wheel
drive, and the front and rear driveshafts are locked to-
gether. The light will illuminate when the transfer case is
shifted into the 4H position.
NOTE:Do not attempt to shift when only the front or rear
wheels are spinning. The transfer case is not equipped with
a synchronizer, and the front and rear driveshaft speeds
must be equal for a shift to take place. Shifting while the
front or rear wheels are spinning at different speeds can
cause damage to the transfer case.
When operating your vehicle in 4L, the engine speed will
be approximately three times (four times for Rubicon
models) that of the 2H or 4H positions at a given road
speed. Take care not to overspeed the engine.
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the transfer case. Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

CAUTION!(Continued)
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not
