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 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 any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional, immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)
AI-SHIFT
The AI-SHIFT automatically shifts the gear to the suitable position accord-
ing to the driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D posi-
tion. However, operating the “-” paddle shift switch will restrict the func-
tion’s operation. (Shifting the shift lever to the S position cancels the
function.)
CAUTION
When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in
the vehicle skidding to the side or spinning.

IS250/220d/200d_EEGear position display
(vehicles with an automatic transmission only)
Indicates the current gear, and the range of gears
that is available when the shift lever is in the D
or S position. The gear range is shown by the
number of dots () and the current gear is shown
as a number. The transmission automatically
selects the gears within the driver selected gear
range.
In the illustration to the left, a range of 6 available
gears (1 through 6) has been selected by the driver.
(The shift lever is in the D or S position with 6
ranges enabled.) It is possible for the transmission
to automatically select between all 6 of the gears.
In this case, the transmission has selected third
gear.
System check display
After switching the “ENGINE START STOP” switch to IGNITION ON
mode, “CHECK” is displayed while system operation is checked. When the
system check is complete, “COMPLETED” is displayed before returning to
the normal screen.
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
When stopped, or driving at low speeds (less than 20 km/h [12 mph])
When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
