If the engine does not start
The engine immobilizer system may not have been deactivated. (P. 9 6 )
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 any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional, immediately.
Auto power off function
If the vehicle is left in ACCESSORY mode for more than an hour with the
shift lever in P (vehicles with an automatic transmission), the “ENGINE
START STOP” switch will automatically turn OFF.
Electronic key battery depletion

The “ENGINE START STOP” switch
indicator will flash in green and a mes-
sage will be shown on the multi-informa-
tion 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 press the
accelerator 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 sec-
onds.
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
IGNITION ON mode for long periods without the engine running.
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.

Select a shift position appropriate for the driving conditions.
Shifting the shift lever
While the “ENGINE START STOP” switch is in IGNI-
TION ON mode, depress the brake pedal and move the
shift lever.

Selecting shift ranges in the D position (if equipped)
To drive using temporary shift range selection, operate the “-” shift
paddle switch. The shift range can then be selected by operating
the “-” and “+” shift paddle switches. Changing the shift range
allows restriction of the upper limit of the gears to be used, pre-
venting unnecessary upshifting and enabling the level of engine
braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1
to 6, will be displayed in the
meter cluster.
To return to normal D position
driving, the “+” shift paddle
switch must be held down for a
period of time.

IS250/220d/200d_EEShift ranges and their functions
A lower shift range will provide greater engine braking force than a
higher shift range.
Shift rangeFunction
6Automatically selecting gears between 1 and 6
according to vehicle speed and driving conditions.
5Automatically selecting gears between 1 and 5
according to vehicle speed and driving conditions.
4Automatically selecting gears between 1 and 4
according to vehicle speed and driving conditions.
3Automatically selecting gears between 1 and 3
according to vehicle speed and driving conditions.
2Automatically selecting gears between 1 and 2
according to vehicle speed and driving conditions.

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 “+” shift pad-
dle 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.
Higher shift range
Lower shift range
The selected shift range, from 1
to 6, will be displayed in the
meter cluster.
The initial shift range in S mode is automatically set to 5 or 4
according to vehicle speed. However, the initial shift range may be
set to 3 or 2 if the AI-SHIFT has operated while the shift lever was
in the D position.

When the “-” shift paddle switch is operated in the D position
When the “-” shift paddle switch is operated in the D position, a shift range
will be automatically selected. The highest gear of the first shift range will
be one gear lower than the gear in use during normal D position driving.
Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following
situations:
When the vehicle comes to a stop
When range 6 is selected and the accelerator pedal is depressed
If the accelerator pedal is depressed for more than a certain period of
time
To protect automatic transmission
A function is adopted that automatically selects a higher shift range when
the fluid temperature is high.
Gear range display when driving
The current gear is displayed on the multi-information display. (P. 184)
Downshifting restrictions warning buzzer
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 or shift paddle switch is operated. (The
warning buzzer will sound twice.)
When driving with the cruise control system or dynamic radar cruise control
system
Engine braking will not occur during shift range selection in the D position
or S mode, even when downshifting to range 5 or 4. (P. 198, 202)
Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP”
switch is turned off after driving in snow mode.
If the shift lever cannot be shifted from P
