lever to the S position. The shift
ranges can be selected by oper-
ating the shift lever. Changing
the shift range allows restriction
of upper limit of the gears to be
used, preventing unnecessary
upshifting and enabling the level
of engine braking force to be
selected.
1Upshifting
2 Downshifting
The selected shift range, from S1 to
S6, will be displayed on the multi-
information display.
The initial shift range in S mode
is set automatically to S4 or S5
according to vehicle speed.
■S mode
●You can choose from 6 levels of
accelerating force and engine
braking force.
●A lower shift range will provide
greater accelerating force and
engine braking force than a higher
shift range, and t he engine revolu-
tions will also increase.
●To prevent the e ngine from over-
revving, upshifti ng may automati-
cally occur when the shift range is
4 or lower.
●When the shift range is 4 or lower,
holding the shift lever toward “+”
sets the shift range to 6.
■Downshifting restriction warn-
ing buzzer
To help ensure safety and driving
performance, dow nshifting opera-
tion may sometimes be restricted. In
some circumstances, downshifting
may not be possible even when the
shift lever is opera ted. (A buzzer will
sound twice.)
■If the “S” indi cator does not
come on or the “D” indicator is
displayed even after shifting the
shift lever to S
This may indicate a malfunction in
the transmission system. Have the
vehicle inspected by your Toyota
dealer immediately. (In this situa-
tion, the transmission will operate in
the same manner as when the shift
lever is in D.)
