To enter S mode, shift the shift lever to S. Shift ranges can be selected by operat-
ing the shift lever or paddle shift switches (if equipped), allowing you to drive in
the shift range of your choice. The shift range can be selected by operating the
shift lever or the “-” and “+” padd le shift switches (if equipped).
Upshifting
Downshifting
The selected shift range, from S1 to S6,
will be displayed on the meters.
The initial shift range in S mode is auto-
matically set to S4 or S5 according to
the vehicle speed.
■Shift ranges and their functions
●You can choose from 6 levels of acce lerating force and engine braking
force.
●A lower shift range will provide gr eater accelerating force and engine
braking force than a higher shift rang e, and the engine revolutions will also
increase.
●If you accelerate while in ranges 1 to 4, the shift range may automatically
increase in accordance with the vehicle speed.

■When the “-” paddle shift switch is operated with the shift lever in the D position (vehi-
cles with paddle shift switches)
The shift range is downshifted to a range that enables engine braking force that is suit-
able to driving conditions.
■Automatic deactivation of shif t range selection in the D position (vehicles with paddle
shift switches)
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed fo r more than a certain period of time
●When the shift lever is shifted to a position other than D
■S mode
●When the shift range is S4 or lower, holding the shift lever toward “+” sets the shift
range to S6.
●Automatically selects a higher shift range before the engine speed becomes too high.
■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifti ng operation may sometimes
be restricted. In some circum stances, downshifting may not be possible even when the
shift lever or paddle shift sw itch (if equipped) is operated . (A buzzer will sound twice.)
■When driving with cruise control, dynamic radar cruise control or dynamic radar
cruise control with full-speed range activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because crui se control, dynamic radar cruise control or
dynamic radar cruise control with full-speed range will not be canceled.
●Vehicles without paddle shift switches: While driving in S mode, downshifting to 5 or 4.
(  P. 311, 323, 335)
●Vehicles with paddle shift sw itches: While driving in D or S mode, downshifting to 5 or

■Restraining sudden start (Drive-Start Control)
When the following unusual operation is performed, the hybrid system output may be
restrained.
●When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D includes S)
with the accelerator pedal depressed, a wa rning message appears on the multi-infor-
mation display. If a warning message is shown on the multi- information display, read the

WARNING
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.

If the shift lever is in N, the hybrid battery (traction ba ttery) will not be charged even
when the engine is running. Therefore, if the vehicle is left with th e shift lever in N for a
long period of time, the hybrid battery (t raction battery) will discharge, and this may
result in the vehicle not being able to start.
