Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
Vehicles without a smart key system:
While the engine switch is in the “ON” position, move the
shift lever with the brake pedal depressed.
Vehicles with a smart key system:
While the “ENGINE START STOP” switch is in IGNITION
ON mode, move the shift lever with the brake pedal
depressed.
When shifting the shift lever between P and D, make sure that the
vehicle is completely stopped.

Shift position purpose
*1: Shifting to the D position allows the system to select a gear suitable
for the driving conditions. Setting the shift lever to the D position is
recommended for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of thepossible gear ranges, controls engine braking forces, and prevents
unnecessary upshifting.

■
Shift ranges and their functions
●Automatically selecting gears between 1 and 6 according to
vehicle speed and driving conditi ons. But, the gear is limited
according to selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide greater engine br aking 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 auto-
matically selects a higher shift range before the engine speed becomes
too high.
● To protect the automatic transaxle, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■ When driving with the cruise contro l or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( P. 295, 300)
■ If the shift lever cannot be shifted from P
● P. 780
● 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”.

■If the “S” indicator does not come on even after 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.)
■ Downshift restriction warning 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.)
■ 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.)
■ Driving on a downhill
On declines, there may be case where the vehicle shifts down automatically
to obtain engine braking. As a result of the downshifting the engine speed
may increase.
CAUTION
■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.

Tur n signal lever
■Turn signals can be operated when
Vehicles without a smart key system:
The engine switch is in the “ON” position.
Vehicles with a smart key system:
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ If the indicator flashes faster than usual
Check that a light bulb in the front or rear turn signal lights has not burned
out.
The turn signal lever can be used to show the following intentions of
the driver:
Right turn
Left turn
Lane change to the right
(push and hold the lever
partway)
The right hand signal will flash
until you release the lever.
Lane change to the left
(push and hold the lever
partway)
The left hand signal will flash
until you release the lever.

NOTICE
■To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (

*1: These lights turn on when the “ENGINE START STOP” switch isturned to IGNITION ON mode (vehicles with a smart key system) or
the engine switch is turned to the “ON” position (vehicles without a
smart key system) to indicate that a system check is being per-
formed. They will turn off after the engine is started, or after a few
seconds. There may be a malfunction in a system if a light does not
come on, or if the lights do not turn off. Have the vehicle inspected
by your Toyota dealer.
*2: The light flashes to indicate that the system is operating.
*3: The light turns on when the system is turned off. The light flashesquickly to indicate that the system is operating.
