Adaptive shift control (ASC) GUID-F11A26ED-2920-48C5-B33E-4D8F7EBFD667
The adaptive shift control system automa-
tically operates when the transmission is
in the "D" (drive) and "DS" (Drive Sport)
position and selects an appropriate gear
depending on the road conditions such as
uphill, downhill or curving roads.
Control on uphill and curving roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Control on downhill roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
The adaptive shift control system shifts to
a low gear that suits the degree of the slope, and uses the engine braking to
reduce the number of times that the brake
must be used.
Control on winding roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel-
erator pedal is depressed.
NOTE:
. Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift
to a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by
the accelerator pedal when the vehicle
is in the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes
maintains a lower gear for a longer
period of time than when adaptive shift
control is not operating. Engine speed will be higher for a specific vehicle
speed while ASC system is operating
than when ASC is not operating.
MANUAL TRANSMISSION GUID-55540C91-1BB1-4931-BE6A-9E10E00B9B1A
WARNING . Do not downshift abruptly on slippery
roads. This may cause a loss of control.
. Do not over-rev the engine when shifting
to a lower gear. This may cause a loss of
control or engine damage.
CAUTION . Do not rest your foot on the clutch pedal
while driving. This may damage the
clutch.
. Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
. Stop your vehicle completely before
shifting into R (Reverse).
. When the vehicle is stopped for a period
of time, for example at a stop light, shift
to N (Neutral) and release the clutch

To change gears, or when upshifting or
downshifting, fully depress the clutch
pedal, shift into the appropriate gear, then
slowly and smoothly release the clutch
pedal.
This vehicle is equipped with a short throw
shifter manual transmission. To ensure
smooth gear changes, fully depress the
clutch pedal before operating the shift
lever. If the clutch pedal is not fully
depressed before the transmission is
shifted, a gear noise may be heard.
Transmission damage could occur. Start the vehicle in 1st gear and shift to
2nd, 3rd, 4th, 5th and 6th gear in
sequence according to vehicle speed.
To back up, depress the shift lever and
then move it to the R (Reverse) gear after
stopping the vehicle completely.
The shift lever returns to its original
position when the shift lever is moved to
the N (Neutral) position.
If it is difficult to move the shift lever into
the R (Reverse) or 1st gear, shift to the N
(Neutral) position, and then release the
clutch pedal once. Fully depress the clutch
pedal again and shift into the R (Reverse)
or 1st gear.
Suggested upshift speeds GUID-34BBD803-93B2-4C9A-A203-4D769208DB15
The following are suggested vehicle
speeds for shifting into a higher gear.
