engine under any circumstances.

Doing so may cause an accident result-

ing in death or serious injury.

■

until the vehicle reaches a safe and com-

plete stop. Activation of the steering lock

in this circumstance may lead to an acci-

dent, resulting in death or serious injury.

NOTICE

■

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 immedi-

ately.

■

Automatic engine shut off feature

●

The vehicle is equipped with a feature

that automatically shuts off the engine

when the shift position is in P with the

engine running for an extended period.

●

The engine will automatically shut off

after approximately 1 hour if it has been

left running while the shift position is in P.

●

The timer for the automatic engine shut

off feature will reset if the brake pedal is

depressed or if the shift position is in a

position other than P.

●

After the vehicle is parked, if the door is

locked with the door lock switch (



P.98)

from the inside or the mechanical key

from the outside, the automatic engine

shut off feature will be disabled. The timer

for the automatic engine shut off feature

will be re-enabled if the driver’s door is

opened.

■

Locking the door from outside with the

WARNING

■

Stopping the engine in an emergency

●

If you want to stop the engine in an

emergency while driving the vehicle,

press and hold the engine switch for

more than 2 seconds, or press it briefly

3 times or more in succession.

(



P.416)

However, do not touch the engine

switch while driving except in an emer-

gency. Turning the engine off while

driving will not cause loss of steering

or braking control, however, power

assist to the steering will be lost. This

will make it more difficult to steer

smoothly, 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 mes-

sage will be shown on the multi-infor-

mation display and a buzzer sounds.

●

When restarting the engine after an

emergency shutdown, press the

engine switch.

■

When parking

Exhaust gases include harmful carbon

monoxide (CO), which is colorless and

odorless. Observe the following precau-

tions.
Failure to do so may cause exhaust gases

to enter the vehicle and may lead to an

accident caused by light-headedness, or

may lead to death or a serious health

hazard.

●

If the vehicle is in a poorly ventilated

area or a closed area, such as a

garage, stop the engine.

a situation cannot be avoided, park the

vehicle in an open space and ensure

that exhaust fumes do not enter the

vehicle interior.

●

Do not leave the engine running in an

area with snow build-up, or where it is

snowing. If snowbanks build up around

the vehicle while the engine is running,

exhaust gases may collect and enter

the vehicle.

WARNING

■

For the shift lever

●

Do not remove the shift lever knob or

use anything but a genuine Lexus shift

lever knob. Also, do not hang anything

on the shift lever.

Doing so could prevent the shift lever

from returning to position, causing

unexpected accidents to occur when

the vehicle is in motion.

●

In order to prevent the shift position

from accidentally being changed, do

not touch the shift lever when not using

them.

■

P position switch

●

Do not press the P position switch

while the vehicle is moving.

If the P position switch is pressed when

driving at very low speeds (for example,

directly before stopping the vehicle), the

vehicle may stop suddenly when the shift

position switches to P, which could lead

to an accident.

●

In order to prevent the shift position

from accidentally being changed, do

not touch the P position switch when

not using them.

NOTICE

■

Notes regarding shift lever and P

position switch operation

Avoid repeatedly operating the shift

lever and P position switch in quick suc-

cession.

The system protection function may acti-

vate and it will not be temporarily possi-

ble to shift the shift position other than P.

If this happens, please wait for a while

before attempting to change the shift

position again.

■

When exiting the vehicle (driver’s

seat only)

Check that the shift position indicator

shows P and that the parking brake indi-

cator is illuminated before opening the

door and exiting the vehicle.

Snow mode automatic deactivation

Snow mode is automatically deactivated if

the engine switch is turned off after driving

in snow mode.

To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range switches to a
range that enables engine braking
force that is suitable to driving condi-
tions. When the “+” paddle shift switch
is operated, the shift range switches to
a range that is one range higher than
the current range.
Changing the shift range allows
restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.

Except F SPORT models

Upshifting

Downshifting

The selected shift range, from D1 to D10,

will be displayed on the meter.
To return to normal D position driving, the
“+” paddle shift switch must be held down
for a period of time.

A lower shift range will provide greater
engine braking forces than a higher shift
range.

■

Automatic deactivation of shift range

selection in the D position

Shift range selection in the D position will

be deactivated in the following situations:

●

When the vehicle comes to a stop

●

If the accelerator pedal is depressed for
