2624-5. Using the driving support systems
■Operation conditio ns of each function
● Lane departure alert function
This function operates when all of the following conditions are met.
• LDA is turned on.
• Vehicle speed is approximately 32 mph (50 km/h) or more.
• System recognizes white (yellow) lines.
• Width of traffic lane is approximately 9.8 ft. (3 m) or more.
• Turn signal lever is not operated.
• Vehicle is driven on a straight road or around a gentle curve with a radius
of more than approximately 492 ft. (150 m).
• No system malfunctions are detected. ( P. 482)
● Vehicle sway warning function
This function operates when all of the following conditions are met.
• Setting for “ warning” in screen of the multi-information display is set to on. ( P. 105)
• Vehicle speed is approximately 32 mph (50 km/h) or more.
• Width of traffic lane is approximately 9.8 ft. (3 m) or more.
• No system malfunctions are detected. ( P. 482)
■ Temporary cancellation of functions
When the operation conditions are no longer met, a function may be tempo-
rarily canceled. However, when the operation conditions are met again, oper-
ation of the function is automatically restored. ( P. 262)
■ Lane departure alert function
The warning buzzer may be difficult to hear due to external noi se, audio play-
back, etc.
■ Vehicle sway warning function
Depending on the vehicle and road conditions, the warning may n ot operate.
■ White (yellow) lines are on ly on one side of road
The LDA system will not operate for the side on which white (ye llow) lines
could not be recognized. When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer
sounds and a warning message urging
the driver to rest and the symbol shown in
the illustration are simultaneously dis-
played on the multi-information display.

2864-5. Using the driving support systems
■The system can be operated when
●The engine switch is in ON mode.
● Intuitive parking assist function is on.
● The vehicle speed is less than about 6 mph (10 km/h).
● A shift position other than P is selected.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’
front and rear bumpers.
● The following situations may occur during use.
• Depending on the shape of the object and other factors, the de tection dis-
tance may shorten, or detection may be impossible.
• Detection may be impossible if static objects draw too close to the sen- sor.
• There will be a short delay between static object detection and display (warning buzzer sounds). Even at low speeds, there is a possibi lity that
the object will come within 11.9 in. (30 cm) before the display is shown
and the warning buzzer sounds.
• It might be difficult to hear the buzzer due to the volume of the audio sys- tem or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.
■ Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting i t. Pay partic-
ular attention to the following objects:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the dir ection of your
vehicle
■ Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is frozen. (Thawing the area will resolve this problem .)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.

2924-5. Using the driving support systems
Rear Cross Traffic Alert buzzer (Rear Cross Traffic Alert funct ion
only)
When a vehicle approaching from the right or left rear of the v ehicle is
detected, a buzzer sounds from behind the left-hand rear pillar .
■The outside rear view mirror indicators visibility
When under strong sunlight, the outside rear view mirror indica tor may be dif-
ficult to see.
■ Rear Cross Traffic Alert buzzer hearing
Rear Cross Traffic Alert function may be difficult to hear over noises such as
high audio volume.
■ When there is a malfunction in the Blind Spot Monitor system
If a system malfunction is detected due to any of the following reasons, warn-
ing messages will be displayed: ( P. 496)
● There is a malfunction with the sensors
● The sensors have become dirty
● The outside temperature is extremely high or low
● The sensor voltage has become abnormal

4086-1. Maintenance and care
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 Toyot a
Safety Sense P)
Do not allow glass cleaner to contact the lens. Also, do not touch the lens.
( P. 237)

4867-2. Steps to take in an emergency
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■
When the tire pressure warning light comes on (if equipped)
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressur e warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural caus es
(if equipped)
The tire pressure warning light may come on due to natural caus es such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure w ill turn off the
warning light (after several minutes).
■When a tire is replaced with a spare tire (vehicles with the ti re pres-
sure warning system)
The temporary spare tire is not equipped with a tire pressure w arning
valve and transmitter. If a tire goes flat, the tire pressure w arning light will
not turn off even though the flat tire has been replaced with t he temporary
spare tire. Replace the temporary spare tire with the repaired tire and
adjust the tire inflation pressu re. The tire pressure warning l ight will go off
after several minutes.
■Conditions that the tire pressure warning system may not functi on
properly (if equipped)
 P. 4 3 6
■If the tire pressure warning light frequently comes on after bl inking
for 1 minute (if equipped)
If the tire pressure warning light frequently comes on after bl inking for 1
minute when the engine switch is turned to “ON” position (vehic les with-
out a smart key system) or IGNITION ON mode (vehicles with a sm art
key system), have it checked by your Toyota dealer.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy pla ce or an
audio sound.

5327-2. Steps to take in an emergency
■Starting the engine when the battery is discharged (vehicles wi th an
automatic transmission)
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic .
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When recharging or replacing the battery
●Vehicles with a smart key system: In some cases, it may not be possible to
unlock the doors using the smart key system when the battery is dis-
charged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
● The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
● Vehicles with a smart key system: The engine switch mode is mem orized by
the vehicle. When the battery is reconnected, the system will r eturn to the
mode it was in before the battery was discharged. Before discon necting the
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
