While the engine switch is in the “ON” position (vehicles without a
smart key system) or IGNITION ON mode (vehicles with a smart
key system), move the shift lever with the brake pedal
depressed.
When shifting the shift lever between P and D, make sure that the vehi-
cle is completely stopped.

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.
Use when high levels of response and feeling are desirable, such as
when driving in mountainous regions or when overtaking.
Vehicles with monochrome display
Press the “DISP” switch to display
the “ECT PWR” and press and
hold the “DISP” switch.
When power mode is on, the “ECT
PWR” indicator will come on.

4-2. Driving procedures
To enter S mode, shift the shift lever to the S position. The shift ranges
can be selected by operating the shift lever. Changing the shift range
allows restriction of upper limit of the gears to be used, preventing
unnecessary upshifting and enabling the level of engine braking force
to be selected.

■Shift ranges and their functions
A lower shift range will provide grea ter engine braking forces than a
higher shift range.

Driving
■S mode
●When the shift range is 7 or lower, holding the shift lever toward “+” sets the
shift range to 8.
● 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.)
■ Deactivation of power mode
Power mode will be canceled if the engine is turned off after driving in power
mode.
■ 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 because cruise control or dynamic
radar cruise control will not be canceled.
● While driving in S mode, downshifting to 7, 6, 5 or 4. ( P. 236)
● When switching the driving mode to power mode while driving in D.
(P. 234)
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine switch is in the
“ON” position (vehicles without a smart key system) or IGNITION ON mode
(vehicles with a smart key system) and the brake pedal is being depressed.

4-2. Driving procedures
■If the shift lever cannot be shifted from P
●First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there
may be a problem with the shift lock system. Have the vehicle inspected by
your Toyota dealer immediately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to the “LOCK” position (vehicles without a smart
key system) or off (vehicles with a smart key system).
Depress the brake pedal.
● 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 A CCESS SEAT OWNER’S MANUAL”.
Pry the cover up with a flathead
screwdriver or equivalent tool.
To prevent damage to the cover,
cover the tip of the screwdriver with a
rag.
Press the shift lock override button.
The shift lever can be shifted while
the button is pressed.

■If the beep sounds continuously when the shift lever is shifted from P
(vehicles with an AUTO ACCESS SEAT)
The AUTO ACCESS SEAT may not be locked in place.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.
■ 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.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.

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.
