OWNSHIFTING
Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. Downshift progressively. Do not skip gears to avoid
overspeeding the engine and clutch.
NOTE:
Above certain speeds, downshifts may be blocked and not
available.

WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip,
and the vehicle could skid.
CAUTION!
 Skipping gears and downshifting into lower gears at
higher vehicle speeds can damage the engine and
clutch systems. Any attempt to shift into lower gear
with clutch pedal pressed may result in damage to
the clutch system. Shifting into lower gear and
releasing the clutch may result in engine damage.

 When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the
engine which can cause engine damage, and/or
clutch damage, even if the clutch pedal is pressed. If
transfer case is in low range the vehicle speeds to
cause engine and clutch damage are significantly
lower.
 Failure to follow the maximum recommended
downshifting speeds may cause engine damage
and/or damage the clutch, even if the clutch pedal is
pressed.
 Descending a hill in low range with clutch pedal
(Continued) pressed could result in clutch damage.
