Driving
If the engine is stopped with the shift lever in a position other than P, the engine
switch will not be turned off but instead be turned to ACCESSORY mode. Per-
form 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 switch is illuminated in amber and then
press the engine switch once.
Check that the indicator on the engine switch is off.
■Auto power off function
When the shift lever is in P, if the vehicl e 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 switch will automatically turn off. However, this
function cannot entirely prevent battery discharge. Do not leave the vehicle with the
engine switch in ACCESSORY or IGNITION ON mode for long periods of time when
the engine is not running.
■Operation of the engine switch
When operating the engine switch, one short, firm press is enough. If the switch is
pressed improperly, the engine may not start or the engine switch mode may not change.
It is not necessary to press and hold the switch.
■Electronic key battery depletion

■Note for the entry function
→P. 111
■If the engine does not start
The engine immobilizer system may not have been deactivated. ( →P. 6 6 )
Contact your Lexus dealer.
■Steering lock
After turning the engine switch off and opening and closing the doors, the steering wheel
will be locked due to the steering lock func tion. Operating the engine switch again auto-
matically 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
running the engine. After about 10 seconds, the steering lock motor will resume func-
tioning.
■When the engine switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Lexus dealer,
immediately.
■If the electronic key battery is depleted

P. 4 7 9
■If the smart access system with push-button start has been deactivated in a customized
setting
→P. 5 4 3
The green indicator light
on the engine switch
will flash and a message will be shown on the
multi-information display. Press the engine
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 resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance 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 switch for more than 2 seconds, or press it briefly 3 times or more in succes-
sion. ( →P. 4 9 9 )
However, do not touch the engine 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. Th is 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 switch in ACCESSORY or IGNITION ON mode for long
periods of time without the engine running.
●If the indicator on the engine switch is illuminated, the engine switch is not off. When
exiting the vehicle, always check that the engine 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 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 your Lexus dealer immediately.
■Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

Automatic transmission
While the engine 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.
*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 driv-
ing.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible gear ranges, controls engine braking forces, and prevents unnecessary upshifting.

GX 460 _O M_ OM6 0K 80 U_ (U)4-2. Driving procedures
When the shift lever is in the S position, the shift lever can be operated as follows:
Upshifting
Downshifting
The selected shift range, from 1 to 6, will
be displayed in the meter.
The initial shift range in S mode is set
automatically to 5 or 4 according to
vehicle speed. However, the initial shift
range may be set to 3 or 2 if AI-SHIFT
has operated while the shift lever was in
the D position. ( →P. 1 8 9 )
■Shift ranges and their functions
●You can choose from 6 levels of engine braking force.
●A lower shift range will provide greate r engine braking force than a higher
shift range, and the engine speed will also increase.
Changing shift ranges in S mode

Driving
■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.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to
6.
■AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shif t lever is in the D position. (Shifting the
shift lever to the S position cancels the function.)
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( → P. 2 1 4 , 2 1 7 )
■If the shift lever cannot be shifted from P
→P. 5 4 2
■If the “S” indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the vehicle
inspected by your Lexus 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)
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downsh ifting 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 th e vehicle to spin or skid, resulting in an
accident.
