IS300h_EE(OM53C61E)
When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meets or exceeds the threshold level while
the vehicle is being driven within the operational speed range, the system
becomes operational and raises the rear portion of the hood.
Sensors

Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the Pop Up
Hood system raises the rear portion of the hood to reduce the possibility of a
serious impact to the pedestrian’s head area by adding clearance to the
engine compartment.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driven within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the front bumper. Also, depending on the impact
conditions or vehicle speed, the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may operate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object
Pop Up Hood operational conditions
CAUTION
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has oper-
ated will further raise the hood and may cause an injury.
Do not drive with the hood raised, as doing so may block the driver’s vision, possibly
causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be lowered by
hand, doing so may deform the hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional. If the
Pop Up Hood has operated, stop the vehicle in a safe place and contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift-
ers may be hot and burn you.

■Pop Up Hood precautions
●Make sure to close the hood before driving, as the system may not operate properly if
the hood is not fully closed.
●Make sure that all 4 tires are of the specified size and inflated to the specified tire
pressure (→P. 568). If tires of a different size are used, the system may not operate
properly.
●If something has hit the area around the front bumper, the sensors may be damaged
even if the Pop Up Hood has not operated. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so may
cause accidental operation or prevent the system from operating properly. If repair or
replacement is necessary, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Do not remove such components as the front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system from oper-
ating properly.
●Do not install anything to the front bumper or hood, as doing so may prevent the sen-
sors from detecting an impact correctly and prevent the system from operating prop-
erly.
●Do not close the hood with force or apply load to the lifters, as doing so may damage
the lifters and prevent the system from operating properly.
●Do not modify the suspension, as changes made to the vehicle height may prevent

1523-2. Opening, closing and locking the doors and trunk
IS300h_EE(OM53C61E)
■Note for the entry function (if equipped)
●Even when the electronic key is within the effective range (detection areas), the system
may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened.
●Do not leave the electronic key on top of the instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outside the cabin and the doors will become lockable from the
outside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be locked or
unlocked by anyone. However, only the doors detecting the electronic key can be used
to unlock the vehicle.
●The doors may unlock or lock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash, when the electronic key is within the effective range.
(The doors will automatically be locked after approximately 30 seconds if the doors
are not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic key is near
the vehicle, there is a possibility that the door may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In this case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the vehicle. (Take
care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry & start sys-
tem. (→P. 1 5 0 )
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the multi-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●A sudden handle operation or a handle operation immediately after entering the effec-
tive range may prevent the doors from being unlocked. Touch the door unlock sensor
and check that the doors are unlocked before pulling the door handle again.
●Unlocking the vehicle may take more time if another electronic key is within the effec-
tive range.

■Tire information
●Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater than
the recommended value when towing. (→P. 5 6 8 )
●Increase the air pressure of the trailer tires in accordance with the total trailer weight
and according to the values recommended by the manufacturer of your trailer.
■Break-in schedule
Lexus recommends that vehicles fitted with new power train components should not be
used for towing trailers for the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for the towing hitch/bracket hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the load
exerted on the vehicle. Also make sure that you will not be towing a load that exceeds
the maximum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mirrors should be added to the vehicle if the traffic
behind cannot be clearly seen with standard mirrors. Adjust the extending arms of
these mirrors on both sides of the vehicle so that they always provide maximum visibility
of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for towing
due to the greater weight burden placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitching ball and bracket after towing for approximately
1000 km (600 miles).
NOTICE
■When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that area.
When steel and aluminum come into contact, there is a reaction similar to corrosion,
which will weaken the section concerned and may result in damage. Apply a rust inhib-
itor to parts that will come in contact when attaching a steel bracket.

■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s front corner
and rear bumpers.
●Certain vehicle conditions and the surrounding environment may affect the ability of
the sensor to correctly detect obstacles. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• 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.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape,
signs and other objects may be judged by the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow
speeds, there is a possibility that the obstacle will come within the sensor’s detection
areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the sensor may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow
noise of the air conditioning system.

CAUTION
■When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possibly
cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially the sides of the vehi-
cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
NOTICE
■When using Lexus parking assist-sensor
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●The Lexus parking assist-sensor operation display flashes, and a beep sounds when
no obstacles are detected.
●If the area around a sensor collides with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display shows continuously without beeping, except when the buzzer mute
switch has been turned on.
●If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it is likely that
the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
