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.

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

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

Gauges and meters
The units used on the speedometer, tachometer gauge display and
multi-information display may differ depending on the model/type.
The following gauges, meters and display illuminate when the
“ENGINE START STOP” switch is in IGNITION ON mode.
Engine coolant temperature gauge
Displays the engine coolant temperature. If the temperature is too
high, the display will flash.
Engine oil temperature gauge
Displays the engine oil temperature. If the temperature is too high,
the display will flash.
Odometer and trip meter
Odometer: Displays the total distance the vehicle has been driven.
Trip meter:Displays the distance the vehicle has been driven since
the meter was last reset. Trip meters “A” and “B” can be
used to record and display different distances inde-
pendently.
Multi-information display

Changing units for the digital speedometer (right-hand drive vehicles only)
Units for the digital speedometer can be changed between km/h and mph by
pushing and holding the odometer/trip meter reset button while the odome-
ter is displayed. At this time, all the units for the multi-information display
will also change.
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. In this case, wait until the display
changes and take care not to downshift again, causing rapid and excessive
engine braking 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
indicates the maximum engine speed.
The following may indicate that the engine is overheating. Immediately
stop the vehicle in a safe place. (P. 465)
• The display on the engine coolant temperature gauge flashes
• The display on the engine oil temperature gauge flashes

CAUTION
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 help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, immedi-
ately if this occurs.
Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. (P. 425)
