■If the engine does not start
The immobilizer system may not have been deactivated. (→P. 8 5 )
■When the steering lock cannot be released
■When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Lexus
dealer immediately.
■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 cannot entirely prevent bat-
tery 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.
■Electronic key battery depletion
→P. 3 5
■When the electronic key battery is discharged
→P. 4 8 2
■Conditions affecting operation
→P. 3 3 The green indicator light on the “ENGINE
START STOP” switch will flash and a mes-

CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not press the accelera-
tor pedal while starting the engine under any circumstances.
Doing so may cause 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, push and
hold the “ENGINE START STOP” switch for more than 3 seconds.
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 12 volt battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNITION
ON mode for long periods if the engine is not running.
■When starting the engine
●Do not race the engine.
●If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
While the “ENGINE START STOP” switch is in IGNITION
ON mode, depress the brake pedal and move the shift lever.
■ Shift position uses
*1: To improve fuel consumption and reduce noises, set the shift lever in the
“D” position for normal driving.
*2: By selecting shift ranges using “S” mode, you can control engine braking forces.

■Shift ranges and their functions
●You can choose from 8 levels (GS460) or 6 levels (GS350) of
engine braking force.
● A lower shift range will provide greater engine braking force than a
higher shift range, and the engine revolutions will also increase.
● If you accelerate while in ranges “1” to “7” (GS460) or “1” to “5”
(GS350), the shift range may automatically range up in accordance
with the vehicle’s speed.
● A higher shift range is automatically selected when the automatic
transmission fluid temperature is high.
■“S” mode
●When the shift range is “6” (GS460) or “4” (GS350) or lower, holding the shift
lever toward “+” sets the shift range to “8” (GS460) or “6” (GS350).
●To prevent the engine from over-revving, upshifting may automatically occur.
■Downshifting restrictions warning buzzer (in the “S” mode)
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever is operated. (The warning buzzer will sound twice.)
■When driving with the cruise control syst em (or dynamic radar cruise control sys-
tem)
The engine brake will not operate in the “S” mode, even when downshifting to “7”,
“6”, “5” or “4” (GS460) or “5” or “4” (GS350). ( →P. 165, 169)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned to ACCESSORY or IGNITION ON mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light not
come on when you turn to IGNITION ON mode, this could mean that these sys-
tems are not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by your Lexus dealer immediately if
this occurs.
■Warning lights
Warning lights inform the driver of malfunctions in the indicated
vehicle’s systems. ( →P. 5 3 4 )
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is on, or after a few seconds.
There may be a malfunction in a system if the lights do not come on, or
turn off. Have the vehicle inspected by your Lexus dealer.
