When driving
IS F_U
Selecting gears in the M positionTo 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.

2-1. Driving procedures
IS F_U
■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.
■If the automatic transmission fluid te mperature warning message is displayed
■AI-SHIFT
The AI-SHIFT automatically selects the suitable 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.

2-2. Instrument cluster
IS F_U■
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.)
