2-1. Driving procedures
Automatic transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever and selecting a shift position
While the “ENGINE
START STOP” switch is
in IGNITION ON
mode, depress the brake
pedal and move the shift
lever.
*: To improve fuel efficiency and
reduce noises, set the shift lever
in the D position for normal driv-
ing.

2-1. Driving procedures
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 automatically
changed in the following situations:
●When vehicle speed drops (downshift only).
●When the automatic transmission fluid or engine coolant temperature
is low.

134
2-1. Driving procedures
■Downshift restrictions warning buzzer
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 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. 158, 161)
■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 7 5
■If is not displayed after shifting the shift lever to M
●Within a few seconds of turning the “ENGINE START STOP” switch to IGNI-
TION ON mode, the transmission will not go into M mode if the shift lever is
moved to the M position. This is because a system check is being performed. In
this case, wait a moment and then try moving the shift lever to the M position
again.
●If the display does not change to on an occasion other than that
described above, it may indicate a malfunction in the automatic transmission
system. Have your vehicle inspected by your Lexus dealer immediately.
■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 vehicle is on
a slippery road, the transmission will automatically shift to 2nd gear for stopping
and starting off.

When driving
■If the automatic transmission fluid temperature warning message is displayed
■AI-SHIFT
The AI-SHIFT automatically selects the optimal gear according to driver perfor-
mance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. How-
ever, operating the “-” paddle shift switch will restrict the function’s operation. (Shift-
ing 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 vehi-
cle skidding to the side or spinning.
If the automatic transmission fluid tempera-
ture warning message is displayed while driv-
ing, 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 mes-
sage 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 your Lexus dealer.

When driving
■Gear position display
Indicates the current gear, and the range of gears
that is available when the shift lever is in the D posi-
tion. 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 automatically 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 displayed.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver's downshifting and the new gear
number appearing on the display. This lag could cause the driver to downshift again,
causing rapid and excessive engine braking and possibly an accident resulting in
death or serious injury.
