the engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result in
serious vehicle damage or personal
injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer,
(such as the dynamometers used by
some states for emissions testing), or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.

.
Remember not to drive at high speeds
for extended periods of time in lower
than 7th gear. This reduces fuel econ-
omy.
. Moving the selector lever rapidly to the
same side twice will shift the ranges in
succession.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
. When the transmission does not shift
to the selected gear, the Automatic
Transmission (AT) position indicator
light (on the dot matrix liquid crystal
display) will blink and the chime will
sound. .
In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a
stop. When accelerating again, it is
necessary to shift up to the desired
range.

must be used.
Control on winding roads:
GUID-D73A39BF-43C8-459F-9C24-47B7F579C407A 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 TRANSMISSIONGUID-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
