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 the vehicle, press and
hold the engine switch for more than 2 seco nds, or press it briefly 3 times or more in
succession. ( P. 501)
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.
■When parking
Exhaust gases include harmfu l carbon monoxide (CO), which is colorless and odor-
less. Observe the fo llowing precautions.
Failure to do so may cause exhaust gases to enter the vehicle and may lead to an acci-
dent caused by light-headedness, or may le ad 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 ru nning 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.

■If a warning message is displayed
on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the system
●In the following situations, perform the acti ons specified in the table. When the normal
operating conditions are detected, the message will disappear and the system will
become operational.
If the message does not disappear, contact your Lexus dealer.
●In the following situations, if the situatio n has changed (or the vehicle has been driven
for some time) and the normal operating conditions are detected, the message will dis-
appear and the system w ill become operational.
If the message does not disappear, contact your Lexus dealer.
• When the temperature around the radar sens or is outside of the operational range,
such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when
driving in the dark, snow, or fog, or when bright lights are shining into the front cam-
era
SituationActions
When the area around a sensor is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or othe r foreign matterTo clean the part of the windshield in front of
the front camera, use the windshield wipers or
the windshield defogger of the air conditioning
system (P. 380).
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as after the vehi-
cle had been parked in the sun, use the air con-
ditioning system to de crease the temperature
around the front camera.
If a sunshade was used when the vehicle was
parked, depending on its type, the sunlight
reflected from the surface of the sunshade
may cause the temperature of the front cam-
era to become excessively high.
If the front camera is cold, such after the vehicle
is parked in an extremely cold environment, use
the air conditioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, su ch as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.

PCS (Pre-Collision System)
◆Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the po
ssibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
The pre-collision system uses a radar sensor and camera sensor to detect
vehicles and pedestrians in front of yo ur vehicle. When the system determines
that the possibility of a frontal collision with a vehicle or pedestrian is high, a
warning operates to urge the driver to take evasive action and the potential
brake pressure is increased to help the driver avoid the collision. If the system
determines that the possibility of a fr ontal collision with a vehicle or pedes-
trian is extremely high, the brakes are automatically applied to help avoid the
collision or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning timing can
be changed. ( P. 238)

LDA (Lane Departure Alert)
When driving on roads with white (yellow)
lines, this function alerts the driver
when the vehicle might depart from its lane.
The LDA system recognizes visible
white (yellow) lines with the camera
sensor on the upper portion of the front
windshield.
◆Lane departure alert function
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on the
multi-information display, and either
the warning buzzer sounds or the
steering wheel vibrates to alert the
driver.
