NOTICE
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. 570). 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 authorized Lexus dealer or repairer, or another duly quali-
fied 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 prop-
erly. 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 operating properly.
Do not install anything to the front bumper or hood, as doing so may prevent
the sensors from detecting an impact correctly and prevent the system from
operating properly.
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 the system from operating properly.

For safety and security
IS300h_EE(OM53B95E)
Tilt sensor detection considerations (if equipped)
The sensor may trigger the alarm in the following situations:
The vehicle is transported by a ferry, trailer, train, etc.
The vehicle is parked in a parking garage.
The vehicle is inside a car wash that moves the vehicle.
Any of the tires loses air pressure.
The vehicle is jacked up.
An earthquake occurs or the road caves in.
NOTICE
To ensure the intrusion sensor function correctly
Installing accessories other than genuine Lexus parts or leaving objects
between the driver’s seat and front passenger’s seat may reduce the detection
performance.
To ensure that the sensors operate prop-
erly, do not touch or cover them.
Do not spray air fresheners or other prod-
ucts directly into the sensor holes.

Driving
IS300h_EE(OM53B95E)
When starting off on an uphill
The hill-start assist control will activate. (P. 286)
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be especially
slippery.
Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting control or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
When the brake pedal is depressed while sport mode is selected
Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 800 km (500 miles):
Do not tow a trailer.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake
system needs bedding-down of the brake shoes periodically or whenever the
parking brake shoes and/or drum are replaced. Have any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, perform the bed-
ding down operation.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 564)

2054-1. Before driving

Driving
IS300h_EE(OM53B95E)
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. 570)
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 extend-
ing arms of these mirrors on both sides of the vehicle so that they always pro-
vide 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 nor-
mal 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 cor-
rosion, which will weaken the section concerned and may result in damage.
Apply a rust inhibitor to parts that will come in contact when attaching a steel
bracket.

Louder
Lower
When the dial is turned to the lowest
volume, driving sound will be turned
off and the indicator will go off.
ASC is enabled when
The vehicle is being driven in normal mode or sport mode. (P. 283)
Situations that may disable the ASC system
The ASC system may be disabled depending on the driving conditions, such as
when the tires slip due to sudden acceleration.
ASC (Active Sound Control)

: If equipped
The ASC system is an electronic sound system that generates driving
sound, conveying the kinetic situations of the vehicle’s acceleration and
deceleration to the driver through the speakers behind the instrument
panel. The vehicle’s response to the driver’s acceleration behavior and
shift operations are also conveyed in sound. When sport mode is
selected, the sound conveyed to the driver will be louder.

2684-5. Using the driving support systems
IS300h_EE(OM53B95E)
When driving on a road surface that is bright due to reflected light
When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
When sunlight or the headlights of oncoming vehicles are shining directly into
the camera lens
When driving on roads that are branching or merging
When driving on a road surface that is wet due to rain, previous rainfall, stand-
ing water, etc.
When the vehicle experiences strong up-and-down motion such as when driv-
ing on an extremely rough road or on a seam in the pavement
When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
When driving on winding roads or roads that are uneven
When driving on rough or unpaved roads
When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
Warning messages for the LDA system
Warning messages are used to indicate a system malfunction or to inform the
driver of the need for caution while driving. (P. 518)
