LDA (Lane Departure Alert)
While driving on a road that has lane markers, this system recognizes
the lane markers using a camera as a sensor to alert the driver when
the vehicle deviates from its lane.
If the system judges that the vehicle has deviated from its lane, it
alerts the driver using a buzzer and indications on the meter.

harm your vehicle’s paint.
● Rear spoiler may not be washable in some automatic car washes. There
may also be an increased risk of damage to vehicle.
■ High pressure car washes
● Vehicles with a canvas top: Do not use the high pressure car washes.
● Do not allow the nozzles of the car wash to come within close proximity of
the windows.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ Aluminum wheels (if equipped)
● Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical clean-
ers.
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.
WARNING
■ When cleaning the windshield
Installation area of front sensor on windshield: P. 191
■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc., to catch fire.
■ Precautions regarding the exhaust pipe

NOTICE
■Cleaning detergents
● Do not use the following types of detergent, as they may discolor the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
● Do not use a polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:
● Remove any dust or dirt from leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.
■ When cleaning the inside of the windshield (vehicles with front sensor)
Be careful not to touch the front sensor ( P. 188).
If the camera is accidentally scratched or hit, PCS and LDA may not oper-
ate properly or may cause a malfunction.

■When to replace your vehicle’s tires
Tires should be replaced if:
● The treadwear indicators are showing on a tire.
● You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage
● A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
■ Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
■ Low profile tires (vehicles with 165/60R15 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
■ If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Your vehicle is equipped with a tire pressure warning system.
While the vehicle is in motion, the system monitors the fluctuations in
the wheel speed signals that are output by the speed sensor for the
brake control system.
It informs the driver if it detects a low tire inflation pressure.
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized when
changing the tire
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■The initialization operation
● Make sure to carry out initialization after adjusting the tire infla-
tion pressure. Also, make sure the tires are cold before carrying
out initialization or tire inflation pressure adjustment.
● If you accidentally press the reset switch when initialization is not
necessary, adjust the tire inflation pressure to the specified level
when the tires are cold, and conduct initialization again.
