Recommended Vehicle Shift Speeds
To utilize your manual transmission effi-
ciently for both fuel economy and perfor-
mance, it should be upshifted as listed inrecommended shift speed chart. Shift at the
vehicle speeds listed for acceleration. When
heavily loaded or pulling a trailer these rec-
ommended up-shift speeds may not apply.
Manual Transmission Shift Speeds in MPH (KM/H)
Engine Speeds 1 to 2 2 to 3 3 to 4 4 to 5 5 to 6
3.6LAccel. 15 (24) 24 (39) 34 (55) 47 (76) 56 (90)
Cruise 10 (16) 19 (31) 27 (43) 37 (60) 41 (66)
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, down-
shifting at the right time provides better ac-
celeration when you desire to resume speed.
Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip, and the ve-
hicle 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 dam-
age to the clutch system. Shifting into
CAUTION!
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 pre-
vent 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 recom-
mended downshifting speeds may cause
the engine damage and/or damage the
