■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-collision syst em will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights and/or warning mess ages will turn on or flash. (P. 535, 542)

■Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collisions system instea d of normal braking operations under any
circumstances. This system will not prevent collisions or lessen damage or injuries in all
cases. Do not overly rely on this system. Failu re to do so may cause an accident, result-
ing in death or serious injury.
This system has been designed to help av oid and reduce the impact of collisions. How-
ever, the system operates differently depending on the situation ( P. 243, 244). As a
result, the same level of performance may not be expected in all cases. Also, the pre-
collision’s brakes may not operate if the driver is depressing the brake pedal or turning
the steering wheel, as the system will dete rmine such conditions as collision avoidance
operations.

■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-
collision system is intended to assist the
driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are
limits to the degree of assistance the system can provide, so please keep in mind the
following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of the vehicle,
and only within a limited range. It is not a mechanism that allows careless or inatten-
tive driving, and it is not a system that can assist the driver in low-visibility conditions. It
is still necessary for the driver to pay cl ose attention to the vehicle’s surroundings.
●Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data available to
the pre-collision system is that from obstacle s it has detected directly in front of the
vehicle. Therefore, it is absolutely necess ary for the driver to remain vigilant and to
determine whether or not there is a possib ility of collision in any given situation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feat ure is designed to help reduce the sever-
ity of a collision, and so only acts when the system has judged that a collision is
unavoidable. This system is not capable of automatically avoiding a collision or bring-
ing the vehicle to a stop safely without appropriate operations performed by the
driver. For this reason, when encountering a dangerous situation the driver must take
direct and immediate action in order to ensure the safety of all involved.
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When water or snow thrown up by the surrounding vehicles hinders the functioning
of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage com-
partment etc.)
●Vehicles that cut in suddenly
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:
●Keep the sensor and front grille cover clean at all times.
Clean the sensor and front 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 posi tion, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Lexus dealer.
●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.
●If the sensor needs to be replaced, contact your Lexus dealer.

Interior features
Drive the vehicle at 5 mph
(8 km/h) or less in a circle until a
direction is displayed.
If there is not enough space to drive
in a circle, drive around the block
until a direction is displayed.
■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped immediately after turning.
●The vehicle is on an inclined surface.
●The vehicle is in a place where the earth’s magnetic field is subject to interference by
artificial magnetic fields (underground car park/parking lot, under a steel tower,
between buildings, roof car park/parking lot, near an intersection, near a large vehicle,
etc.).
●The vehicle has become magnetized. (There is a magnet or metal object near the inside
rear view mirror.)
●The 12-volt battery has been disconnected.
●A door is open.

■While driving the vehicle
Do not adjust the display. Adjust the di splay only when the vehicle is stopped.
■When doing the circling calibration
Secure a wide space, and watch out for people and vehicles in the vicinity. Do not vio-
late any local traffic rules while performing circling calibration.
NOTICE
■To avoid compass malfunctions
Do not place magnets or any metal object s near the inside rear view mirror.
Doing this may cause the compass sensor to malfunction.
■To ensure normal operation of the compass
●Do not perform a circling calibration of the compass in a place where the earth’s
magnetic field is subject to interfer ence by artificial magnetic fields.
●During calibration, do not operate electric systems (moon roof, power windows, etc.)
as they may interfere with the calibration.

Maintenance and care
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use hard brushes or
abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving for
long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period.Clean the windows with a soft, da mp cloth as soon as possible.
• Do not use wax or glass cleaners that co ntain abrasives when cleaning the windows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can be
repaired. Contact your Lexus dealer.
WA R N I N G
■When washing the vehicle
Do not apply water to the inside of the en gine compartment. Doing so may cause the
electrical components etc. to catch fire.
■When cleaning the windshield (vehicles with rain-sensing windshield wipers)
●When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps into the raindrop
sensor
■Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the switch is in “AUTO”, the wipers may oper-
ate unexpectedly in the following situations,
and may result in hands being caught or other
serious injuries and cause damage to the wiper
blades.

ent tone for 20 more seconds.
Front passenger’s seat belt buzzer:
The front passenger’s seat belt buzzer sounds to alert the front passenger that his or
her seat belt is not fastened. The buzzer sounds once if the vehicle reaches a speed of
12 mph (20 km/h). If the seat belt is still unfastened after 30 seconds, the buzzer will
sound intermittently for 10 seconds. Then, if the seat belt is still unfastened, the buzzer
will sound in a different tone for 20 more seconds.
