Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both
fuel economy and performance, it should be upshifted as
listed in 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.
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
3.6L Accel. 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 recom-
mended 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.
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.
