Driving and Operating 9-9
Shifts may be more noticeable with
a cold transmission. This difference
in shifting is normal.
M (Manual Mode): This position
lets drivers select the range of gears
appropriate for current driving
conditions. If the vehicle has this
feature, see Manual Mode on
page 9‑9.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
The vehicle has a shift stabilization
feature that adjusts the transmission
shifting to the current driving
conditions to reduce rapid upshifts
and downshifts. If the shift
stabilization feature determines that
a current vehicle speed cannot be
maintained, the transmission does
not upshift. In some cases, this may
appear to be a delayed shift,
however the transmission is
operating normally.
Manual Mode
Range Selection Mode
The Range Selection Mode controls
the vehicle's transmission.
To use this feature:
1. Move the shift lever to the
M (Manual Mode).
2. Press the plus/minus button to
upshift or downshift selecting the
desired range of gears.
A number displays next to the M,
indicating the current gear that has
been selected. The number
displayed in the gear indicator is the
highest gear that can be used. The
vehicle can automatically shift to
lower gears as it adjusts to driving
conditions. When 3 (Third) is
selected, 1 (First) through 3 (Third)
gears are automatically shifted by
the vehicle, but 4 (Fourth) cannot be
used until it is selected.
The Range Selection Mode controls
the vehicle and engine speed while
driving down a hill or towing a trailer,
by allowing you to select a desired
range of gears.
