When driving
IS F_EE
Selecting gears in the M position
To enter M mode, shift the shift lever to the M position. Gears can
then be selected by operating the shift lever or paddle shift
switches, allowing you to drive in the gear of your choosing.
Upshifting
Downshifting
The gear changes once every
time the shift lever or paddle
shift switch is operated.
The selected gear, from 1 to 8,
will be displayed in the meter
cluster.
When in the M position, the gear will not change unless the shift
lever or paddle shift switches are operated.
However, even when in the M position, the gears will be automati-
cally changed in the following situations:
When vehicle speed drops (downshift only).
When the automatic transmission fluid or engine coolant tem-
perature is low.

When driving
IS F_EE
Rev indicator
Downshift 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 paddle shift switch is operated. (A
buzzer will sound twice.)
When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur during shift range selection in the D position,
even when downshifting to range 7, 6, 5 or 4. (P. 180, 184)
Automatic deactivation of snow mode and “Sport” mode
If the “ENGINE START STOP” switch is turned OFF after driving in either
snow mode or “Sport” mode, the mode is automatically deactivated.
If the shift lever cannot be shifted from P
P. 4 5 6
Automatic gear selection when the vehicle is stopped
When the vehicle comes to a stop, the transmission will automatically
downshift to allow you to start off in 1st gear.
When the vehicle is idling at high rpm in order to warm up, and the vehi-
cle is on a slippery road, the transmission will automatically shift to 2nd
gear for stopping and starting off.
When the shift lever is in D (paddle
shift switches operated) or in M, an
indicator on the tachometer illuminates
in 3 steps in the case of high engine
speeds to encourage the driver to
upshift.
If the third (red) segment illuminates, a
buzzer will also sound

2-1. Driving procedures
IS F_EE
If the automatic transmission fluid temperature warning message is dis-
played
AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to 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 M 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.
If the automatic transmission fluid tem-
perature warning message is displayed
while driving, make sure you return to
normal D position driving and reduce
speed by easing off the accelerator
pedal. Stop the vehicle in a safe place,
shift the shift lever to the P position and
let the engine idle until the warning
message goes out.
When the warning message goes out,
the vehicle can be driven again.
If the warning message does not go out
after waiting a while, have your vehicle
inspected by any authorized Lexus
dealer or repairer, or another duly qual-
ified and equipped professional

2-2. Instrument cluster
IS F_EEGear position display
Indicates the current gear, and the range of gears
that is available when the shift lever is in the D
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 8 available
gears (1 through 8) has been selected by the driver.
(The shift lever is in the D position with 8 ranges
enabled) It is possible for the transmission to auto-
matically select between all 8 of the gears. In this
case, the transmission has selected third gear.
When in the M position, the “F” mark is dis-
played.
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.)
Changing units for the multi-information display

authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
