4-2. Driving procedures
CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accel-
erator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors
until the vehicle reaches a safe and complete stop. Activation of the steering lock in
this circumstance may lead to an accident, resulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and
hold the “START STOP ENGINE” switch for more than 2 seconds, or press it
briefly 3 times or more in succession. (→P. 6 1 5 )
However, do not touch the “START STOP ENGINE” switch while driving except in
an emergency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will make it
more difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so.

■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be suspended if
the hybrid system is turned on and off repeatedly in a short period of time. In this
case, refrain from operating the hybrid system. After about 10 seconds, the steering
lock motor will resume functioning.
■When “Check Access System with Elec. Key” is displayed on the multi-information
display
The system may be malfunctioning. Have the vehicle inspected by your Lexus dealer
immediately.
■If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the “POWER” switch
with the shift lever in P and the brake pedal depressed, contact your Lexus dealer
immediately.

4-2. Driving procedures
Automatic transmission (gasoline vehicles)
While the “START STOP ENGINE” switch is in IGNITION ON
mode, move the shift lever with the brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: Shifting the shift lever to D allows the system to select a gear suitable for the driv-ing conditions.
Setting the shift lever to D is recommended for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible gearranges, controls engine braking force, and prevents unnecessary upshifting.

■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 5 4 )
■Downshifting 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 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 automatic 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. 6 76
■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.)

the brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: To improve fuel efficiency and reduce noises, set the shift lever in D for normaldriving.
*2: By selecting shift ranges using S mode, you can control engine braking forces.
