RX450h_U_OM0E013U 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 “+” paddle 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 greater 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.Selecting shift ranges in the S position 1

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 shift range select ion 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 for 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, holdin g 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 performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever or paddle shift switch (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 cruise 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 switches: While dr iving in D or S mode, downshifting to 5 or

When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆ Pre-collision brake assist
When the system determines that the po ssibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
◆ Pre-collision braking
* 3
When the system determines that the po ssibility of a frontal collision is high,
the system warns the driver. If the system determines that the possibility of a
collision is extremely high, the brakes are automatically applied to help avoid
the collision or reduce the collision speed.
* 3
: Depending on the region in which the vehi cle was sold, the pre-collision braking func-
tion may not be available.
◆ Suspension control (if equipped)
When the system determines that the po ssibility of a frontal collision is high,
the Adaptive Variable Suspension System (  P. 382) will control the damping
force of the shock absorbers.
