158 STARTING AND OPERATING
(Continued)
SHIFTING
Fully press the clutch pedal before shifting gears. As you
release the clutch pedal, lightly press the accelerator
pedal.
You should always use FIRST gear when starting from a
standing position.
NOTE:
A certain amount of noise from the transmission is normal.
This noise can be most noticeable when the vehicle is
idling in NEUTRAL with the clutch engaged (clutch pedal
released), but it may also be heard when driving. The noise
may also be more noticeable when the transmission is
warm. This noise is normal and is not an indication of a
problem with your clutch or transmission.
Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both fuel
economy and performance, it should be upshifted as
listed in the recommended shift speed chart. Shift at the
vehicle speeds listed for acceleration. When heavily
loaded or pulling a trailer these recommended up shift
speeds may not apply.
NOTE:
Vehicle speeds shown in the chart above are for 2H and
4H only, vehicle speeds in 4L would be significantly less.
DOWNSHIFTING
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.

Cruise 10 (16) 19 (31) 40 (64) 55 (88) 65 (105)
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 depressed may result 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 down-
shifting 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
depressed could result in clutch damage.
CAUTION!
