1324-2. Driving procedures
*1: To improve fuel efficiency and reduce noise, shift the shift lever to D for normal
driving.
*2: Any gear range can be fixed when driv-ing in M mode.
■To protect the automatic transmission
If the automatic transmission fluid tempera-
ture is high, “Transmission Fluid Temp High
See Owner’s Manual” will be displayed on
the multi-information display and the vehi-
cle will go into transmission protection
mode automatically. Have the vehicle
inspected by your Lexus dealer.
■When driving with dynamic radar cruise
control activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not occur
because dynamic radar cruise control will
not be canceled.
●While driving in the D position, down-
NOTICE
■To prevent battery discharge
Do not stop the engine when the shift
lever is in a position other than P. If the
engine is stopped in another shift lever
position, the engine switch will not be
turned off but instead be turned to
ACCESSORY mode. If the vehicle is left
in ACCESSORY mode, battery dis-
charge may occur.

■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, downshifting operation may some-
times be restricted. In some circumstances,
downshifting may not be possible even
when the paddle shift switch is operated. (A
buzzer will sound twice.)
To enter M mode, shift the shift lever to
M. Gears can then be selected by
operating the shift lever or paddle shift
switches, allowing you to drive in the
gear of your choosing.
1 Upshifting
2 Downshifting
The gear changes once every time the shift
lever or paddle shift switch is operated.
The selected gear, from M1 to M8, will be
fixed and displayed on the meter.
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 situation:

When vehicle speed drops (down-
shift only).
 When a gear change is necessary to
protect the engine or automatic
transmission when the engine cool-
ant temperature or automatic trans-
mission fluid temperature is low, or
other reasons.
In the following situations, the gear will
not shift even if the shift lever or paddle
shift switches are operated.
 “Slippery Road. Cannot Shift to
Lower Gear” is displayed on the
multi-information display.
 The vehicle speed is low (upshift
only).
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, 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.)

2Eco drive mode
Helps the driver accelerate in an
eco-friendly manner and improve fuel
economy through moderate throttle char-
acteristics and by controlling the operation
of the air conditioning system (heat-
ing/cooling).
When not in Eco drive mode, if the driving
mode select switch is turned to the left, the
Eco drive mode indicator will come on.
3Sport mode
•SPORT S mode
Controls the transmission and engine to
provide quick, powerful acceleration. Also,
gear shift timing is co ntrolled to suit sporty
driving, making this mode is suitable for
when agile driving response is desired,
such as when driving on roads with many
curves.
When not in SPORT S mode, if the driving
mode select switch is turned to the right,
the “SPORT S” indicator will come on.
•SPORT S+ mode
Provides earlier down shift timing than
SPORT S mode in order to maintain a high
engine speed and provides faster gear
changes. This mode also changes the
steering feel, suspension control and
VDIM control, making it suitable for pow-
erful sporty driving. When in SPORT S mode, if the driving
mode select switch is turned to the right,
the “SPORT S+” indicator will come on.
■Operation of the air conditioning sys-
tem in Eco drive mode
Eco drive mode controls the heating/cool-
ing operations and fan speed of the air con-
ditioning system to enhance fuel efficiency
(  P.213). To improve air conditioning per-
formance, adjust the fan speed or turn off
Eco drive mode.
■Automatic deactivation of sport mode
and custom mode
If the engine switch is turned off after driv-
ing in sport mode or custom mode, the
drive mode will be changed to normal
mode.
■Driving mode pop-up display (vehicles
with a 10.3-inch display)
When the driving mode is changed, the
selected driving mode will be temporarily
displayed on the side display. ( P.210)
