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 (
from the inside or the mechanical key
from the outside, the automatic engine

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.
(
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.

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.
