4-2. Driving procedures
*1: Shifting to the D position allows the system to select a gear suitable forthe driving conditions. Setting the shift lever to the D position is recom-
mended for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possi-ble gear ranges, controls engine braking forces, and prevents unneces-
sary upshifting.
To enter S mode, shift the shift lever to S. Shift ranges can be selected
by operating the shift lever, allowing you to drive in the shift range of
your choosing. The shift range ca n be selected by the shift lever.
Upshifting
Downshifting
The selected shift range, from 1 to
6, will be displayed on the multi-
information display.
The initial shift range in S mode is
set automatically to 5 or 4 accord-
ing to vehicle speed. However, the
initial shift range may be set to 3 if
the AI-SHIFT has operated while
the shift lever was in the D position.

Driving
■Shift ranges and their functions
●Automatically selecting gears bet ween 1 and 6 according to vehi-
cle speed and driving conditions. But, the gear is limited accord-
ing to selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide gr eater engine braking force than
a higher shift range, and the engine speed will also increase.
■ S mode
●When the shift range is 5 or lower, holding the shift lever toward “+” sets the
shift range to 6.
● To prevent excessive engine speed, a function was adopted that automati-
cally selects a higher shift range before the engine speed becomes too high.
● To protect the automatic transaxle, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
■ Downshift restriction wa rning buzzer (S mode)
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ When driving with the cr uise control or dynamic radar cruise control
activated (if equipped)
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while driving in S mode and down-
shifting to 5 or 4 because cruise control or dynamic radar cruise control will
not be canceled. ( P. 257, 261)
■ If the shift lever cannot be shifted from P
●P. 580
● Vehicles with AUTO ACCESS SEAT: If the AUTO ACCESS SEAT has not
been locked in place after being stowed, the shift lever cannot be shifted
from P.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.

4-2. Driving procedures
■If “S” does not come on even afte r shifting the shift lever to S
This may indicate a malfunction in the automatic transaxle system. Have the
vehicle inspected by your Toyota dealer immediately. (In this situation, the
transaxle will operate in the same manner as when the shift lever is in D.)
■ AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position cancels the function.)
WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

Turn signal lever
Right turn
Left turn
Lane change to the right (move
the lever partway and release
it)
The right hand signals will flash 3
times.
Lane change to the left (move
the lever partway and release
it)
The left hand signals will flash 3
times.
■Turn signals can be operated when
The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).
■ If the indicator flashes faster than usual
Check that a light bulb in the front or rear turn signal lights has not burned
out.
■ If the turn signals stop flashing before a lane change has been per-
formed
Operate the lever again.
■ To discontinue flashing of the turn signals during a lane change
Operate the lever in the opposite direction.

Headlight switch
Turning the end of the lever turns on the lights as follows:
The illustration is intended as an example.
The headlights can be operate d manually or automatically.
Operating instructions
U.S.A.Canada
The headlights, side marker, parking lights, daytime running
lights (if equipped) and so on turn on and off automatically
(when the engine switch is in the “ON” position [vehicles
without a smart key system] or IGNITION ON mode [vehi-
cles with a smart key system]).
The side marker, parking, tail, license plate, daytime run-
ning lights (if equipped) and instrument panel lights turn on.
The headlights and all lights listed above (except daytime
running lights) turn on.

■Daytime running light system (if equipped)
●Bulb type: To make your vehicle more visible to other drivers, the headlights
turn on automatically (at a reduced intensity) whenever the engine is started
and the parking brake is released. Daytime running lights are not designed
for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
LED type: To make your vehicle more visible to other drivers, the daytime
running lights turn on automatically whenever the engine is started and the
parking brake is released. Daytime running lights are not designed for use
at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

■Automatic light off system
Vehicles without a smart key system
● When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch is turned to the
“ACC” or “LOCK” position. (The lights turn off immediately if on the
key is pressed after all the doors are locked.)
● When only the tail lights are on: The tail lights turn off automatically if the
engine switch is turned to the “ACC” or “LOCK” position and the driver’s
door is opened.
To turn the lights on again, turn the engine switch to the “ON” position, or turn
the light switch off once and then back to the
or .
Vehicles with a smart key system
● When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch is turned to
ACCESSORY mode or turned off. (The lights turn off immediately if
on the key is pressed after all the doors are locked.)
● When only the tail lights are on: The tail lights turn off automatically if the
engine switch is turned to ACCESSORY mode or turned off and the driver’s
door is opened.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or
turn the light switch off and then back to or .
■ Light reminder buzzer
Vehicles without a smart key system
A buzzer sounds when the engine switch is turned to the “LOCK” position, the
key is removed and the driver’s door is opened while the lights are turned on.
Vehicles with a smart key system
A buzzer sounds when the engine switch is turned off and the driver’s door is
opened while the lights are turned on.
■ Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 625)
NOTICE

■The Automatic High Beam can be operated when
The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).
■ Camera sensor detection information
●High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve.
• When the vehicle is cut in front of by another.
● High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.
● Houselights, streetlights, red traffic signals, and illuminated billboards or
signs may cause the high beam to turn off.
● The following factors may affect the amount of time taken to turn high beam
on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and
preceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage
● High beam may be turned on or off when unexpected by the driver.
