Operation of the “ENGINE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to press
and hold the switch. ■
When the steering lock cannot be released
■
If the engine does not start
The engine immobilizer system may not have been deactivated. ( P. 117)
Contact your Lexus dealer. ■
When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Lexus
dealer immediately. ■
Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes with the shift
lever in P, the “ENGINE START STOP” switch will automatically turn off. However,
this function cannot entirely prevent ba ttery discharge. Do not leave the vehicle
with the “ENGINE START STOP” switch in ACCESSORY mode for long periods
of time when the engine is not running. ■

CAUTION■
When starting the engine
Always start the engine while sitting in th e driver’s seat. Do not depress the acceler-
ator while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.■
Stopping the engine in an emergency
If you want to stop the engine in an em ergency while driving the vehicle, press and
hold the “ENGINE START STOP” switch fo r more than 2 seconds, or press it
briefly 3 times or more in succession. ( P. 8 7 8 )
However, do not touch the “ENGINE START STOP” 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 thes e 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.
NOTICE■
To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNITION
ON mode for long periods without the engine running.■
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 malfunction with the “ENGINE START STOP” switch
If the “ENGINE START STOP” seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Contact your
Lexus dealer immediately.

■ Shifting the shift lever
While the “ENGINE START STOP” switch is in IGNITION ON
mode, depress the brake pedal and move the shift lever.

1802-1. Driving procedures
LX570_OM_OM60L21U_(U) ■ Shift position uses
* 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 recom-
mended for normal driving.
* 2
: If equipped, by selecting shift ranges using paddle shift switches, you can
control engine braking forces.
* 3
: Selecting shift ranges using “S” mode restricts the upper limit of the possi-
ble gear ranges, controls engine br aking forces, and prevents unneces-
sary upshifting. Shift position Function
P Parking the vehicle or starting the engine
R Reversing

When driving
LX570_OM_OM60L21U_(U) ■ Selecting a driving mode
The following patterns can be selec ted to suit current driving and
operating conditions.
Power mode For powerful acceleration and
driving in mountainous regions.
Normal mode For normal driving.
Second start mode For starting on slippery road
surfaces, such as on snow.
Press “2nd” to return to normal
mode.

LX570_OM_OM60L21U_(U) Changing shift range in “D” position
■ Shift lever
If the shift lever is shifted into the “D” position, the ap propriate gear is
automatically selected, as determ ined by the driving conditions.
■ Paddle shift switches (if equipped)
While the shift lever is in the “D” po sition, engine braking force can be
temporarily switched to.
By firstly operating the “-” paddle sh ift switch, the “-” and “+” switches
can be used to freely switch the shift range.
Changing the shift range allows re striction of the highest gear, pre-
venting unnecessary upshifting and enabling the level of engine brak-
ing force to be selected.
Downshifting
Upshifting To return to normal D position driv-
ing, the “+” paddle shift switch must
be held down for a period of time.

When driving
LX570_OM_OM60L21U_(U) ■ Shift ranges and their functions
● Automatically selecting gears betw een 1 and 6 according to vehicle
speed and driving conditions. But, the gear is limited according to
selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide gr eater engine braking force than a
higher shift range, and the engi ne speed will also increase.

LX570_OM_OM60L21U_(U) Changing shift ranges in “S” mode
When the shift lever is in the “S” posi tion, the shift lever or paddle shift
switches can be operated as follows:
Downshifting
Upshifting
The initial shift range in “S” mode is automatically s et to “5” or “4” accord-
ing to the vehicle’s speed. However, the initial shift range may be set to “3”
or “2” if the AI-SHIFT has operated while the shift lever was in the “D”
position. ( P. 1 8 6 )
