■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline engine will start automatically after a short period of time in order to warm up. In this case, you will
become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illuminated, press the EV drive mode switch before the gasoline en gine starts to switch to EV drive mode.
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the fol- lowing situations. When EV dr ive mode is canceled, a buzzer will sound and the EV drive
mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low. The remaining battery level indicated in the “Energy monitor” display is low.
( P. 128)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill, etc.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters to approxi- mately 2 km (1.2 mile). Howe ver, depending on vehicle conditions, there are situations
when EV drive mode cannot be used.
(The distance that is possible depends on th e hybrid battery [traction battery] level and driving conditions.)
■Fuel economy
The hybrid system is designed to achieve the best possible fuel economy during normal driving (using the gasoline engine and electr ic motor [traction motor]). Driving in EV
drive mode more than necess ary may lower fuel economy.
WARNING
■Caution while driving
When driving in EV drive mode, pay special attention to the area around the vehicle.
Because there is no engine noise, pedestrians, people riding bicycles or other people
and vehicles in the area may not be aware of the vehicle starting off or approaching them, so take extra care while driving.

To drive using temporary shift range selection, operate the “-” paddle shift switch.
Changing the shift range enables the level of engine braking force to be
selected. The shift range can then be sele cted by operating the “-” and “+” paddle
shift switches.
Upshifting
Downshifting
The selected shift range, from D1 to D6, will be displayed in the meter.
The initial shift rang e when the “-” pad-
dle shift switch is operated is automati- cally set to D2, D3, D4 or D5 according
to the vehicle speed.
To return to normal D position driving, the “+” paddle shift switch must be held
down for a period of time.
■Shift ranges and their functions
●You can choose from 6 levels of engine braking force.
●A lower shift range will provide greate r engine braking force than a higher
shift range, and the engine revolutions will also increase.

ing the shift lever or paddle shift switches , allowing you to drive in the shift range
of your choice. The shift range can be sele cted by operating the shift lever or the
“-” and “+” paddle shift switches.
Upshifting
Downshifting
The selected shift range, from S1 to S6, will be displayed in the meter.
The initial shift range in S mode is auto-
matically set to S2, S3, 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
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 selection in the D position
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
■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circum stances, downshifting may not be possible even when the
shift lever or paddle shif t switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if th e power switch is turned off after driving in
snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because crui se control or dynamic radar cruise control will not be canceled.
●While driving in D or S mode, downshifting to 5 or 4. ( P. 293, 305)
●When switching the driving mode to sport mode while driving in D position. (P. 348)
■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 message and follow the instructions.
●When the accelerator pedal is depressed too while the vehicle is in reverse.
■Shift lock system
The shift lock system is a system to prevent ac cidental operation of the shift lever in start-
ing.
The shift lever can be shifted from P only wh en the power switch is in ON mode and the brake pedal is being depressed.

◆Pre-collision warning
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.
PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a rada r sensor and camera sensor to detect
vehicles and pedestrians*1 in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the driver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that the possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are automatically applied*2 to help
avoid the collision or help reduce the impact of the collision.
The pre-collision system can be disabl ed/enabled and the warning timing can
be changed. ( P. 269)
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer for details.
*2: Depending on the region in which the ve hicle was sold, the pre-collision braking
function (automatic braking function) may not be available. Contact any authorized
Lexus retailer or Lexus authorized repair er, or any reliable repairer for details.

■If the PCS warning light flashes and a warning message is displayed on the multi-infor-
mation display
The pre-collision system may be temporarily unavailable or there may be a malfunction
in the system.
●In the following situations, the warning light will turn off, the message will disappear and the system will become operational when normal operating conditions return:
• When the radar sensor or camera sensor or the area around either sensor is hot,
such as in the sun • When the radar sensor or came ra sensor or the area around either sensor is cold,
such as in an extremely cold environment
• When the radar sensor or front grille embl em is dirty or covered with snow, etc. • When the part of the windshield in front of the camera sensor is fogged up or cov-
ered with condensation or ic e (Defogging the windshield: P. 474)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
●If the PCS warning light continues to flash or the warning message does not disappear, the system may be malfunctioning. Have the vehicle inspected by any authorized Lexus
retailer or Lexus authoriz ed repairer, or any reliable repairer immediately.
■If VSC is disabled
●If VSC is disabled (P. 354), the pre-collision brake assist and pre-collision braking
functions are also disabled.
●The PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake System Unavailable” will be displayed on the multi-information display.
