warning light Lexus IS300h 2013 User Guide

441-1. For safe use
IS300h_EE(OM53B95E)
The main SRS airbag system and Pop Up Hood components are shown
above. The SRS airbag system and Pop Up Hood are controlled by the
airbag sensor assembly. As the airbags deploy, a chemical reaction in the
inflators quickly fills the airbags with non-toxic gas to help restrain the
motion of the occupants. When the Pop Up Hood is activated, a non-toxic
gas is released due to a chemical reaction in the lifters, which causes the
pistons to eject quickly and raise the rear portion of the hood. (Pop Up
Hood: P. 56)

For safety and security
IS300h_EE(OM53B95E)
If a warning light comes on, a warning message is displayed, or the 12-volt bat-
tery is disconnected
The hybrid system may not start. In this case, try to start the system again. If the
“READY” indicator does not come on, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level warn-
ing light (P. 509) go off. If there is only a small amount of fuel, the hybrid sys-
tem may not be able to start. (The minimum amount of fuel to add to make the
low fuel level warning light go out is about 10 L [2.7 gal., 2.2 Imp. gal.], when
the vehicle is on a level surface. This value may vary when the vehicle is on a
slope.)
Electromagnetic waves
High voltage parts and cables on hybrid vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromag-
netic waves as conventional gasoline powered vehicles or home electronic
appliances.
Your vehicle may cause sound interference in some third party-produced radio
parts.
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the
hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).

CAUTION
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come
on when you start the hybrid system, this could mean that these systems are not
available to help protect you in an accident, which could result in death or seri-
ous injury. Have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional immediately if
this occurs.

CAUTION
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are
in front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (P. 254) will not be activated, and a fatal or serious acci-
dent may result.
Vehicles that cut in suddenly
Vehicles traveling at low speeds
Vehicles that are not moving
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Conditions under which the vehicle-to-vehicle distance control may not func-
tion correctly
Apply the brakes as necessary in the following conditions as the radar sensor
may not be able to correctly detect vehicles ahead, and a fatal or serious acci-
dent may result:
When water or snow thrown up by a the surrounding vehicles hinders the
functioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the trunk
etc.)
When the road curves or when the lanes are narrow
When steering wheel operation or your position in the lane is unstable
When the vehicle ahead of you decelerates suddenly
Handling the radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or dam-
age them.
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If
the sensor or surrounding area is subject to a strong impact, always have the
area inspected and adjusted by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
Do not modify or paint the sensor and grille cover.
Do not replace them with non-genuine parts.

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)

2764-5. Using the driving support systems
IS300h_EE(OM53B95E)
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
problem.)
• 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 particu-
lar 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 vehicle
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance 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 sen-
sor’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.
