When stopping the engine with the shift lever in a position other than P
If the engine is stopped with the shift 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
When the shift lever is in P, if the vehicle is left in ACCESSORY or IGNITION ON
mode with the engine not running for more than 20 minutes (ACCESSORY mode)
or one hour (IGNITION ON mode), the “ENGINE START STOP” switch will auto-
matically turn off. However, this function cannot 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 “ENGINE 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. 1 1 5 )
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately.
■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. Operat-
ing 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 suspended
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 2 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 any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional,
immediately.
■If the electronic key battery is depleted
→P. 5 0 1The green indicator light on the “ENGINE
START STOP” switch will flash and a mes-
sage will be shown on the multi-information
display. 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 acceler-
ator 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. Activa-
tion of the steering lock in this circumstance may lead to an accident, 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 2 seconds, or press it
briefly 3 times or more in succession. (→P. 6 0 3 )
However, do not touch the “ENGINE START STOP” switch while driving except in
an emergency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will make it
more difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so.

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 your vehicle
checked by any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional 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 any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional immediately.

■Shift position purpose
*1: Shifting to the D position allows the system to select a gear suitable for the
driving condition. 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 the possi-
ble gear ranges, controls engine braking forces, and prevents unneces-
sary upshifting.

Changing shift ranges in S mode
To enter S mode, shift the shift lever to the S position. The shift range can
then be selected by operating the “-” and “+” paddle shift switches (if
equipped) or the shift lever. Changing the shift range allows restriction of
the upper limit of the gears to be used, preventing unnecessary upshifting
and enabling the level of engine braking force to be selected.
Upshifting
Downshifting
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
AI-SHIFT has operated while the shift lever was in the D position.
(→P. 1 9 1 )
■Shift ranges and their functions
●Automatically selecting gears between 1 and 6 according to vehicle
speed and driving conditions. 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 braking force than a
higher shift range, and the engine speed will also increase.

Selecting shift ranges in the D position (vehicles with paddle shift switches)
To drive using temporary shift range selection, operate the “-” paddle shift
switch. The shift range can then be selected by operating the “-” and “+”
paddle shift switches. Changing the shift range allows restriction of the
upper limit of the gears to be used, preventing unnecessary upshifting
and enabling the level of engine braking force to be selected.
Upshifting
Downshifting
To return to normal D position
driving, the “+” paddle shift switch
must be held down for a period of
time.
