When driving
Pre-collision system (if equipped)
■The pre-collision system may not operate effectively in the following situations:
●When traveling through a curve with objects on the edge of the road.
●When traveling through a curve with another vehicle passing in the opposite
direction.
●Narrow iron bridges.
●Metallic objects on the road.
●A steel plate on the road (e.g., at a construction site).
●When waiting to turn to the left in an in tersection with another vehicle passing in
the opposite direction.
●If your vehicle approaches another vehicle ahead very quickly.
The vehicle reacts to a frontal collision the instant before it happens using fol-
lowing components.
■ Pre-collision sensor
Uses the radar to detect possible obst acles ahead. Sensors then determine in
advance whether a crash is unavoidable.
■ Pre-collision seat belts (Front seat belts only)
Helps enhance their restraint performance by quickly retracting if an acci -
dent is calculated to be inevitable.
■ Pre-collision brake assist system
Once an accident is calculated to be inevitable, increased braking force will
be applied once the brake pedal is pressed.
■ Electronically modulated air suspension control
Once an accident is calculated to be inevitable, the vehicle adjusts the damp -
ing action of the shock absorbers to help keep the vehicle level.

2-4. Using other driving systems
CAUTION
■Pre-collision system limitations
●The Pre-Collision System is designed to help reduce the crash speed and dam-
age in certain frontal collisions only. It is not a collision avoidance system and is
no
t a substitute for safe and attentive driving. System effectiveness depends on
many factors, such as speed, dr iver input and road conditions.
●The sensor is able to detect objects in front of the vehicle within 10 degrees on
either side. If the object is out of range, or there is little to no millimeter wave
reflection, the sensor will not detect the object.
●Even if the system is operative in a collisio n, unless the seat belts are worn and the
brake pedal is depressed, the pre-collision seat belts and brake assist system will
operate.
■Failure Warning
If an error is detected, the master warn i
ng light comes on, a warning tone sounds
and the following warning message appears on the multi-information display.
(  P.334 )

4-1. Maintenance and care
■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
r
ear window defogger heater wires. Use a cloth dampened with lukewarm water to
gently wipe the window clean. Wipe the window in strokes running parallel to the
heater wires.
■Caring for leather seats
Lexus recommends regularly cleaning the interior of the vehicle at least twice a
y
ear to maintain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available.
Use a sponge or brush to apply the foam. Rub in overlapping circles. Do not apply
w
ater. The best results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
Be careful not to splash water or spill liquid on the floor.
Do not get any of the safety system and co ntr
ol units, such as SRS airbags, in the
vehicle interior wet. 
Electrical malfunction may cause the airbag s to deplo
y or not function properly,
resulting in death or serious injury.

4-3. Do-it-yourself maintenance
CAUTION
The engine compartment contains many mechanisms and fluids that many move
suddenly, become hot, or become electrically energized. To avoid death or serious
injury:
■When working in the engine compartment:
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold and power steering
fluid reservoir, etc. right after driving as they may be hot. Oil and other fluids may
also be hot.
●Do not leave anything that may burn easily , such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. 
Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. 
It contains poisonous and corrosive sulfuric acid.
■When the engine is running
Perform maintenance checks with adequate ventilation
■When working near the electric cooling fan or radiator grill:
Be sure the ignition is off. With the igni tion on, th
e electric cooling fan may automat-
ically start to run if the air conditioning is on and/
or if the coolant temperature is
high. ( P.262 )
■When working on or under the vehicle:
●Do not get under the vehicle with just the jack supporting it. 
Always use automotive jack stands or other solid supports.
●Use eye protection to prevent flying or falling material, fluid spray, etc. from get -
ting in your eyes.

CAUTION
■When inspecting or replacing tires
Observe the following instructions, as failure to do so may cause dangerous han-
dling characteristics resulting in loss of contr
ol and could cause death or serious
injury.
• Do not mix radial, bias belted, or bias-ply tir
es on your vehicle, or use tires other
than the manufacturer’s recommended size.
• Do not mix summer and all season tires on your vehicle.
• Do not use tires other than the manufact ur
er’s designated tires, and never mix
tires or wheels of different size to the originals.
NOTICE
■To prevent malfunction of the tire pressure warning system
Do not push the reset switch without adjusting the tire inflation pressure to the spec-
ified level. Otherwise, the low tire pressure warning may not function correctly.
(  P.334 )
■If tire pressure becomes low while driving
Do not continue driving, your ti r
es and/or wheels may be ruined.
