4-2. Driving procedures
■S mode
●When the shift range is S4 or lower, holding the shift lever toward “+” sets the shift
range to S6.
●To prevent excessive engine speed, a function was adopted that automatically
selects a higher shift range before the engine speed becomes too high.
●To protect the automatic transmission, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
■When driving with cruise control activated
Even when performing the following actions with the intent of enabling engine brak-
ing, the engine brake will not operate in the S mode, even when downshifting to 5 or
4. ( P. 2 4 8 )
■Downshifting restrictions 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 is operated. (A buzzer will sound twice.)
■If the S indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the auto matic transmission system. Have the vehi-
cle inspected by your Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift
lever is in D.)
■If the shift lever cannot be shifted from P
P. 8 0 9
■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever
to S cancels the function.)
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting
in an accident.

CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting
in an accident.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid ba ttery (traction battery) will not be charged
even when the engine is running. Therefore, if the vehicle is left with the shift lever
in N for a long period of time, the hybrid battery (traction battery) will discharge,
and this may result in the vehicle not being able to start.

Turn signal lever
Right turn
Lane change to the right (move
the lever partway and then
release it)
The right hand signals will flash 3
times.
Lane change to the left (move the
lever partway and then release it)
The left hand signals will flash 3 times.
Left turn
■Turn signals can be operated when
The “START STOP ENGINE” <“POWER”> switch is in IGNITION ON
mode.
■If the indicator flashes faster than usual
Check that a light bulb in the front or re ar turn signal lights has not burned out.
■If the turn signals stop flashing before a lane change has been performed
Operate the lever again.
■To discontinue flashing of the tu rn signals during a lane change
Operate the lever in the opposite direction.
■Customization
The number of times the turn signals flash during a lane change can be changed.

To change the set speed, operate the lever until the desired set speed is
obtained.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily move
the lever in the desired direction.
Large adjustment: Hold the lever in
the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) each time the lever is oper-
ated.
Large adjustment: The set speed can be increased or decreased continually until
the lever is released.
Pulling the lever toward you can-
cels the constant speed control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes the
constant speed control.
Resuming is available when the vehi-
cle speed is more than approximately
25 mph (40 km/h).

To change the set speed, operate the lever until the desired set speed is
displayed.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily move
the lever in the desired direction.
Large adjustment: Hold the lever in
the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be increased or
decreased as follows: • When the set speed is shown in “MPH”
Fine adjustment: By approximately 1 mph (1.6 km/h) each time the lever is
operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75 sec-
onds the lever is held
• When the set speed is shown in “km/h”
Fine adjustment: By approximately 0.6 mph (1 km/h) each time the lever is
operated
Large adjustment: By approximately 3. 1 mph (5 km/h) for each 0.75 sec-
onds the lever is held
In the constant speed control mode ( P. 259), the set speed will be increased or
decreased as follows:
Fine adjustment: By approximately 1 mp h (1.6 km/h) each time the lever is
operated
Large adjustment: The set speed can be increased or decreased continually
until the lever is released.

Interior features
■Air conditioning odors
●During use, various odors from inside an d outside the vehicle may enter into and
accumulate in the air condit ioning system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditio ning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immedi-
ately after the air conditioning system is started in automatic mode.
■Air conditioning filter

■Customization
Settings (e.g. exhaust gas sensor sensitivity) can be changed.
(Customizable features P. 8 6 3 )
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outs ide air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
