Doing so may cause an accident result-
ing 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 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.

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.292)
However, do not touch the engine switch
while driving except in an emergency.
Turning the engine off while driving will
not cause loss of steering or braking con-
trol, 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 mes-
sage will be shown on the multi-infor-
mation display and a buzzer sounds.
●To restart the engine after performing
an emergency shutdown, shift the shift
lever to N and then 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.
●Do not leave the vehicle with the
engine running for a long time. If such
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.

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 com-
pletely stopped.
■Shift lock system
The shift lock system is a system to prevent
accidental operation of the shift lever in
starting.
The shift lever can be shifted from P only
when the engine switch is in IGNITION
ON mode and the brake pedal is being
depressed.
■If the shift lever cannot be shifted from P
First, check whether the brake pedal is
being depressed.
If the shift lever cannot be shifted with your
foot on the brake pedal, there may be a
problem with the shift lock system. Have the
vehicle inspected by your Lexus dealer
immediately.
The following steps may be used as an
emergency measure to ensure that the shift
lever can be shifted.
Releasing the shift lock:
1 Set the parking brake.
2 Turn the engine switch to off.
3 Depress the brake pedal.

■Driving mode
 P.192
To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range will be
downshifted to a range that enables
engine braking force that is suitable to
driving conditions. When the “+” pad-
dle shift switch is operated, the shift
range will be one gear higher than the
gear in use during normal D position
driving. 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.
1
Upshifting
2 Downshifting
The selected shift range, from D1 to D8,
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 pe dal is depressed for
more than a certai n period of time
WARNING
■To prevent an accident when releas-
ing the shift lock
Before pressing the shift lock override
button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pe dal is accidentally
depressed instead of the brake pedal
when the shift lock override button is
pressed and the shift lever is shifted out
of P, the vehicle may suddenly start, pos-
sibly leading to an accident resulting in
death or serious injury.

■Daytime running light system
●The daytime running lights illuminate
using the same lights as the parking lights
and illuminate brighter than the parking
lights.
●To make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally when all of the following conditions
are met. (The daytime running lights are
not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the or

WARNING
■When using the intuitive parking
assist
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be dr iven safely and pos-
sibly cause an accident.
●Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
●The sensor’s detection areas and reac-
tion times are limited. When moving
forward or reversin g, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensor’s detection areas.
●The area directly under the bumpers is
not detected.
Thin posts or objects lower than a sen-
sor may not be detected when
approached, even if they have been
detected once.
■When to disable the function
In the following situations, disable the
function as it may operate even though
there is no possibility of a collision.
●The vehicle is equipped with a fender
pole, wireless antenna or fog lights.

system will return to normal.
■Sensor detection information
●The following situations may occur
during use.
• The sensors may be able to only detect objects near the front and rear bumpers.
• Depending on the shape of the object and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other systems are sounding.
■Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a sen-
sor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
●There is another vehicle equipped with
parking assist sensors in the vicinity.
●A sensor is coated with a sheet of spray
or heavy rain.
●If a sensor is hit by a large amount of
water, such as when driving on a flooded
road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or
curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly
detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections project-
ing outwards in the direction of your vehi-

■Operating conditions of hill-start assist
control
When the following four conditions are met,
the hill-start assist control will operate:
●The shift lever is in a position other than P
or N (when starting off forward/back-
ward on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in any
of the following situations:
●The shift lever is moved to P or N.
●The accelerator pedal is depressed.
●The parking brake is engaged.
●Approximately 2 seconds elapse after
the brake pedal is released.
■Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the engine is
started or just after the vehicle begins to
move. This sound does not indicate that a
malfunction has occurred in any of these
systems.
●Any of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Reactivation of the TRAC/VSC systems
Even after the TRAC /VSC systems have
been turned off, turn ing the engine off and
then on again will automatically reactivate
the TRAC/VSC systems.
■Reactivation of the TRAC system linked
to vehicle speed
When only the TRAC system is turned off,
the TRAC system will turn on when vehicle
speed increases. Ho wever, when both
TRAC/VSC systems are turned off, the sys-
tems will not turn on even when vehicle
speed increases.
■Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, re frain from excessive
steering input or stop the vehicle and turn
the engine off. The EPS system should
return to normal within 10 minutes.
WARNING
■The ABS does not operate effectively
when
●The limits of tire gripping performance
have been exceeded (such as exces-
sively worn tires on a snow covered
road).
●The vehicle hydroplanes while driving
at high speed on wet or slick roads.
■Stopping distance when the ABS is
operating may exceed that of normal
conditions
The ABS is not designed to shorten the
vehicle’s stopping di stance. Always main-
tain a safe distance from the vehicle in
front of you, especially in the following
situations:
●When driving on dirt, gravel or
snow-covered roads
●When driving over bumps in the road
