When driving
■Rev indicator
■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 contro l or dynamic radar cruise control
Engine braking will not occur during shif t range selection in the D position, even
when downshifting to range 7, 6, 5 or 4. ( P. 166, 169)
■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 8 7
●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
■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 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 po sition cancels the function.)
The engine speed may stay high while depressing the accelerator pedal and may
remain high after releasing the accelerator pedal. This dose not indicate a malfunc-
tion.
CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden accele ration, 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.

CAUTION
■When the temperature of the display is extremely low
Allow the interior of the vehicle to warm up before using the shift position and shift
range/gear display. At extremely low temperatures, the display 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 brakin g and possibly an accident resulting in
death or serious injury.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The following may indicate that the engine is overheating. Immediately stop the
vehicle in a safe place. (
P. 4 9 5 )
• The display on the engine c oolant temperature gauge flashes
• The display on the engine oil temperature gauge flashes

■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on
when you start the engine, this could mean that these systems are not available to

the vehicle inspected by your Lexus dealer immediately if this occurs.
