When stopping the engine with the shift lever in a position other than P
If the engine is stopped with the sh
ift lever in a position other than P,
the “ENGINE START STOP” switch will not be turned off but instead
be turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the “ENGINE START STOP”
switch is illuminated in amber and then press the “ENGINE
START STOP” switch once.
Check that the indicator on the “ENGINE START STOP”
switch is off.
■Auto power off function
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour with the shift lever in P, the “ENGINE
START STOP” switch will automatically turn off. However, this function can-
not entirely prevent battery discharge. Do not leave the vehicle with the
“ENGINE START STOP” switch in ACCESSORY or IGNITION ON mode for
long periods of time when the engine is not running.
■ Operation of the “ENG INE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to
press and hold the switch.

■If the engine does not start
The engine immobilizer system may not have been deactivated. ( P. 106)
■ Steering lock
After turning the “ENGINE START STOP” switch off and opening and closing
the doors, the steering wheel will be locked due to the steering lock function.
Operating the “ENGINE START STOP” switch again automatically cancels
the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■ When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
■ If the electronic key battery is depleted
 P. 528
The green indicator light on the “ENGINE
START STOP” switch will flash. Press the
“ENGINE START STOP” switch again
while turning the steering wheel left and
right.

CAUTION
■
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If the vehicle begins to slide due to engine failure or other circumstances, do
not lock or open the doors until the vehicle reaches a safe and complete
stop. Activation of the steering lock in this circumstance may lead to an acci-
dent, resulting in death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the “ENGINE START STOP” switch for more than 3 seconds.
However, do not touch the “ENGINE START STOP” switch while driving
unless in an emergency. If the engine stops while driving, this could lead to
an unexpected accident.

NOTICE
■To prevent battery discharge
● Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNI-
TION ON mode for long periods of time without the engine running.
● If the indicator on the “ENGINE START STOP” switch is illuminated, the
“ENGINE START STOP” switch is not off. When exiting the vehicle,
always check that the “ENGINE START STOP” switch is off.
● Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the “ENGINE START
STOP” switch will not be turned off but instead be turned to ACCESSORY
mode. If the vehicle is left in ACCESSORY mode, battery discharge may
occur.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
■ Symptoms indicating a malfunction with the “ENGINE START STOP”
switch
If the “ENGINE START STOP” seems to be operating somewhat differently
than usual, such as the switch sticking slightly, there may be a malfunction.
Contact your Toyota dealer immediately.

Automatic transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
Standard type
While the engine switch is in the “ON” position, 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.

Multi-mode typeVehicles 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: To improve fuel efficiency and reduce noises, set the shift lever in the D
position for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the pos-sible gear ranges, controls engine braking forces, and prevents unnec-
essary upshifting.

Changing shift ranges in S mode (multi-mode type)When the shift lever is in the S position, the shift lever can be oper-
ated as follows:
Non-Optitron type meter For upshifting
For downshifting
Optitron type meter For upshifting
For downshifting
The initial shift range in S mode is set automatically to “4” according
to vehicle speed. However, the initial shift range may be set to “3” if
AI-SHIFT has operated while the shift lever was in the D position.
(  P. 177)
■ Shift ranges and their functions
●You can choose from 5 levels of engine braking force.
● A lower shift range will provide greater engine br aking force than
a higher shift ran ge, and the engine speed will also increase.

■
Downshifting restrictions (standard type)
The maximum allowable speeds are as follows.
■ S mode (multi-mode type)
When the shift range is “3” or lower, holding the shift lever toward “+” sets
the shift range to “5”.
■ AI-SHIFT
AI-SHIFT automatically selects the optimal gear according to driver perfor-
mance and driving conditions.
Standard type
AI-SHIFT automatically operates when the shift lever is in the D position.
Multi-mode type
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position cancels the function.)
■ When driving with the cruise control system
Standard type
The engine brake will not operate when downshifting from D to 3. ( P. 209)
Multi-mode type
Engine braking will not occur in S mode, even when downshifting to “4”.

■If the “S” indicator does not come on even after shifting the shift lever
to S (multi-mode type)
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer immediately.
(In this situation, the transmission will operate in the same manner as when
the shift lever is in D.)
■ Downshift restriction warning buzzer (S mode in multi-mode type)
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.)
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.
