Driving If the engine is stopped with the shift le ver in a position other than P, the engine
switch will not be turned off but inst ead be turned to ACCESSORY mode. Per-
form the following procedure to turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that “Turn Off Vehicle” is disp layed on the multi-information display
and then press the engine switch once.
Check that “Turn Off Vehicle” on th e multi-information display is off.■
Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON
mode (the engine is not running) for more than an hour with the shift lever in P, the engine
switch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI-
TION ON mode for long periods of ti me when the engine is not running.■
Operation of the engine switch ●
If the switch is not pressed shortly and firmly, the engine switch mode may not change
or the engine may not start. ●
If attempting to restart the engine immediately after turning the engine switch off, the
engine may not start in some cases. After turning the engine off, please wait a few sec-
onds before restarting the engine. ■

Steering lock
After turning the engine switch off and opening and closing the doors, the steering wheel
will be locked due to the steering lock func tion. Operating the engine switch again auto-
matically cancels the steering lock.When stopping the engine with the shift lever in a position other than P1

Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, the motor may be suspended if the
engine is turned on and off re peatedly in a short period of time. In this case, refrain from
running the engine. After about 10 seconds, the steering lock motor will resume func-
tioning. ■
When “Smart Access System Malfunction See Owner’s Manual” is displayed on the
multi-information display
The system may be malfunctioning. Have th e vehicle inspected by your Lexus dealer,
immediately. ■

If the smart access system with push-button start has been deactivated in a customized
setting
→ P. 546A message will be displayed on the multi-infor-
mation display.
Check that the shift lever is set in P. Press the
engine switch while turn ing the steering wheel
left and right.
WARNING ■
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting 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 cir-
cumstance may lead to an accident, re sulting in death or serious injury.■
Stopping the engine in an emergency ●
If you want to stop the engine in an em ergency while driving th e vehicle, press and
hold the engine switch for more than 2 seco nds, or press it briefly 3 times or more in
succession. ( → P. 511)
However, do not touch the engine switch wh ile driving except in an emergency. Turn-
ing the engine off while drivin g 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. ●
If the engine switch is operated while the vehicle is running, a warning message will be
shown on the multi-information display and a buzzer sounds. ●
When restarting the engine after it was turn ed off while driving, shift the shift lever to
N and press the engine switch.

Driving NOTICE ■
To prevent battery discharge ●
Do not leave the engine switch in AC CESSORY or IGNITION ON mode for long
periods of time without the engine running. ●
If “ACCESSORY” or “IGNITION ON” is disp layed on the multi-information display,
the engine switch is not off. When exitin g the vehicle, always check that the engine
switch is off. ●
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 no t be turned off but
instead be turned to ACCESSORY mode. If the vehicle is left in ACCESSORY
mode, battery discharge may occur. ■
When starting the engine ●
Do not race a cold engine. ●
If the engine becomes difficult to start or stalls frequently, have your vehicle checked
by your Lexus dealer immediately. ■
Symptoms indicating a malfun ction with the engine switch
If the engine switch seems to be operating somewhat differen tly than usual, such as the
switch sticking slightly, ther e may be a malfunction. Contact your Lexus dealer immedi-
ately.

Automatic transmission
While the 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 to the D position allows the system to select a gear suitable for the driving
conditions. Setting the shift lever to the D position is recommended for normal driv-
ing.
* 2
: If equipped, by selecting shift ranges us ing paddle shift swit ches, you can control
engine braking forces.
* 3
: Selecting shift ranges using S mode rest ricts the upper limit of the possible gear
ranges, controls engine braking forces , and prevents unne cessary upshifting.Shifting the shift lever

To drive using temporary shift range selection, operate the “-” or “+” paddle shift
switch.
When the “-” paddle shift switch is oper ated, the shift range will be downshifted
to a range that enables engine braking forc e that is suitable to driving conditions.
When the “+” paddle shift switch is operated, the shift range will be one gear
upper than the gear in use during normal D position driving.
Changing the shift range allows restrictio n of the highest shift range, preventing
unnecessary upshifting and enabling the level of engine braking force to be
selected.
Downshifting
Upshifting The selected shift range, from D1 to
D8, will be displa yed in the meter.
To return to normal D position driv-
ing, the “+” paddle shift switch must
be held down for a period of time.
A lower shift range will provide greater engi ne braking forces than a higher shift
range.Changing shift range in D position (vehicles with paddle shift switches)1

Upshifting
Downshifting
The selected shift range, from 1 to 8,
will be displayed in the meter.
The initial shift range in S mode is set
automatically to 6, 5 or 4 according to
vehicle speed. However, the initial shift
range may be set to 3 or 2 if AI-SHIFT
has operated while the shift lever was in
the D position. ( → P. 214)

Shift ranges and their functions ●
Automatically selecting gears between 1 and 8 according to vehicle speed
and driving conditions. But, the gear is limited according to selected shift
range. ●
You can choose from 8 levels of engine braking force. ●
A lower shift range will provide greate r engine braking force than a higher
shift range, and the engine speed will also increase.Changing shift r anges in S mode 1
