WARNING

⬛

Before using the front corner sensors or reverse sensors

Make sure to observe the following precautions.
Failure to do so is dangerous, as it may lead to an unforeseen accident.

⚫

Do not let the vehicle speed exceed approx. 10 km/h (6 mph).

⚫

There is a limit to the sonar’s recognition range and activation speed. When
you move your vehicle forward or backward, make sure to check the safety

around the vehicle, which is outside the sonar’s recognition range (especially

the sides of the vehicle), use the brake pedal to control the speed adequately

and drive slowly.

⚫

Do not paste stickers or install accessories on the sonar sensors or their sur-
rounding areas.

⚫

Vehicles with TFT color multi-information display: If the warning message
“Sonar Sensor Function Stop” appears, check the sonar conditions. If the

warning message appears even when the sonar is not covered with rain,

snow, ice, or dirt, it could be due to a malfunction of the front corner sensors

or reverse sensors. Have the vehicle inspected at your Toyota dealer.

⬛

: If equipped

Rear-view camera

✽

The rear-view camera is a device designed to assist driving when the

vehicle backs up, such as during parking, by displaying the vehicle’s

rear-view image on the display audio screen.
The operation may differ depending on the display audio your vehi-

cle has. For details, refer to the included instruction manual.

The screen illustration used in this document is an example. The actual

image displayed will be different from this illustration in terms of how the

vehicle appears.

Rear-view camera screen display

When the shift lever is set to R with the engine switch turned “ON”, the dis-

play audio screen shows the vehicle’s rear-view image.

Setting the shift lever to other than R will restore the previous screen.

The rear-view camera image takes precedence over any other screen dis-

play.

The projection range may be different depending on the vehicle and

road conditions.

⚫

The projection range of the rear-view camera is limited. The camera

does not capture items located near both edges of the bumper or those

located under the bumper.

⚫

Since the rear-view camera uses a special lens, the distance in the cam-

era view is different from the actual distance.

⚫

The colors of the rear-view camera image may appear different from the

actual colors.

⚫

Anything placed above the rear-view camera may not appear on the

monitor.

⬛

Camera

The rear-view camera is installed at

the following location.

⚫

Camera maintenance and care
If foreign objects, such as water droplets, snow, or dirt, are attached to

the camera, you cannot see a clear image. In this case, wash out dirt

from the camera with water, and wipe it off with a soft cloth dampened

with water. For persistent stains, wash it off with neutral detergent.

⚫

The following situations may make it difficult to view the screen, but they are
not the sign of malfunction.

⦁

Dark places (such as at night)

⦁

When the temperature near the lens is high or low

⦁

When water droplets are attached to the rear-view camera or the humidity is

high (such as during rain)

Failure to observe the following may cause death or serious injury.

⚫

Do not overly rely on the rear-view camera. Just as when you drive a vehicle
without the rear-view camera, make sure to check the safety around and

behind your vehicle and drive carefully. Be particularly careful not to collide

with the parked vehicles nearby, obstacles, or people.

⚫

When you back up, make sure to check the safety around and behind your
vehicle and drive carefully.

⚫

Never drive the vehicle while looking at the screen only.
The image displayed on the screen may be different from the actual situa-

tion. Note that the projection range of the camera is limited. Never back up

while looking at the screen only. Doing so could get your vehicle hit or lead

to an unforeseen accident. Be sure to confirm the safety around by visually

checking the surroundings with your eyes or using the inside rear view mir-

ror and the outside rear view mirrors before driving.

⚫

Never use it in the situations listed below.

⦁

Frozen, slippery or snowy roads

⦁

When tire chains or spare tires are used

⦁

When the back door is not closed fully

⦁

Camera handling

⚫

Be careful with the following since they could cause the rear-view camera to
malfunction.

⦁

Do not install any item around the camera, which could interfere with the

camera’s field of view (such as an item blocking the view or light-emitting

objects, items made of shiny materials).

⦁

Do not apply strong impact to the camera unit, such as hitting it hard or

bumping it against another object. Doing so could cause the camera posi-

tion or mounting angle to be deviated.

⦁

The camera unit has a waterproof structure. Do not remove, disassemble

or alter it.

⦁

When you wash the camera lens, use water to wash the dirt off from the

camera and wipe it off with a soft cloth dampened with water.
If you rub the camera lens too hard, it could scratch the camera lens, and

you will not be able to see clear images.

⦁

The camera’s cover is made of resin. Do not allow organic solvents, body

wax, oil film remover, and glass coating agent to get attached to it. If they

get attached, wipe it off immediately.

⦁

Do not expose it to rapid temperature changes, such as by pouring hot

water over it in cold weather.

⦁

Do not splash water directly to the camera or areas around the camera

using a high-pressure washer during a car wash. The high water pressure

adds stress and may prevent the system from working properly.

⚫

Applying shock to the camera unit may cause the camera to malfunction.
Have the vehicle inspected at your Toyota dealer in your earliest conveni-

ence.

4-5. Using the driving support systems

Driving assist systems

The following devices automatically operate according to the driving

conditions to improve driving safety and performance. However,

these systems are supplementary and you should be careful not to

over-rely on them while driving.

◆

ABS (Anti-lock Brake System)

Helps to prevent wheel lock when the brakes are applied suddenly, or if

the brakes are applied while driving on a slippery road surface.

◆

Brake assist

Generates an increased level of braking force when the system detects a

panic stop situation.

◆

VSC (Vehicle Stability Control)

Helps the driver to control skidding when swerving suddenly or turning on

slippery road surfaces.

◆

TRC (Traction Control)

Helps to maintain drive power and prevent the drive wheels from spinning

when starting the vehicle or accelerating on slippery roads.

◆

Hill-start assist control

Prevents the vehicle from moving backwards when starting on an uphill.

◆

EPS (Electric Power Steering)

Uses an electric motor to assist steering operation.

◆

4-6. Driving tips

Winter driving tips

Carry out the necessary preparations and inspections before driving

the vehicle in winter. Always drive the vehicle in a manner appropri-

ate to the prevailing weather conditions.

Preparation for winter

⚫

Use fluids that are appropriate to the prevailing outside temperatures.

⦁

Engine oil

⦁

Coolant

⦁

Washer fluid

⚫

Have a service technician inspect the condition of the battery.

Before driving

Perform the following according to the driving conditions:

⚫

Do not try to forcibly open a window or move a windshield wiper that is

frozen. Pour warm water over the frozen area to melt the ice. Wipe away

the water immediately to prevent it from freezing.

⚫

To ensure proper operation of the air conditioning system fan, remove

any snow that has accumulated on the air inlet vents in front of the

windshield.

⚫

Check for and remove any excess ice or snow that may have accumu-

lated on the exterior lights, vehicle’s roof, around the tires or on the

brakes.

⚫

Look under the vehicle and check that there are no ice blocks around

the ground. Remove any attached ice blocks with great care to avoid

damaging vehicle components. Also check that the pedals and steering

wheel move smoothly.

⚫

Remove any snow or mud from the bottom of your shoes before getting

in the vehicle.

239

4-6. Driving tips

riv

When driving the vehicle

⚫

Accelerate the vehicle slowly, keep a safe distance between you and the

vehicle ahead, and drive at a reduced speed suitable to road conditions.

⚫

During snowfall or cold weather, water adhering to the brake system

may freeze, and the brakes may become less effective. If brake perfor-

mance is poor, paying close attention to the surrounding safety, lightly

depress the brake pedal several times to confirm that the brakes work

properly until their effectiveness is restored.

⚫

When driving on snowy roads, snow attached to the back of the wheel

wells freezes and may gradually accumulate, making it difficult to steer.

Check that there is no abnormal build-up of snow from time to time. The

lights may become dark due to snow during driving, so make sure that

there is no abnormal build-up of snow from time to time.

When parking the vehicle

⚫

The parking brake may freeze up, preventing it from being released. For

continuously variable transmission vehicles, set the shift lever to P. For

the manual transmission vehicles, set the shift lever to R on a downhill,

and set it to the gear 1 on an uphill to park. Do not apply the parking

brake at this time, and make sure to use wheel chocks.
Failure to do so may be dangerous because it may cause the vehicle to

move unexpectedly, possibly leading to an unforeseen accident.

⚫

When you park the continuously variable transmission vehicle without

applying the parking brake, confirm that the shift lever will not move*

with the shift lever being placed in P.

The shift lever will be locked if it is attempted to be shifted from P to any other
position without depressing the brake pedal. If the shift lever can be shifted,
there may be a problem with the shift lock system. Have the vehicle inspected at
your Toyota dealer immediately.

WARNING

⬛

When the brakes freeze

If normal braking is not restored, have the vehicle inspected at your Toyota

dealer immediately.

⬛

Caution when parking

When parking without applying the parking brake, be sure to use wheel

chocks. Failure to do so may be dangerous because it may cause the vehicle to

move unexpectedly, possibly leading to an unforeseen accident.

NOTICE

⬛

When removing ice from the windshield and windows

Do not hit and break the ice.
The glass may crack.

⬛

When the doors, windshield wipers, windshield, or windows freeze

⚫

Thaw the ice by applying lukewarm water.
Hot water may damage or deform components.

⚫

If the windshield wipers, outside rear view mirrors, or windows are forcibly
activated while frozen or when snow is strongly attached, the wiper rubber

may be damaged or the motor may break.

⬛

Repairing or replacing snow tires (vehicles with the tire pressure warning
system)

Request repairs or replacement of snow tires from Toyota dealers or legiti-

mate tire retailers.
This is because the removal and attachment of snow tires affects the operation

of the tire pressure warning valves and transmitters.

⬛

Fitting tire chains (vehicles with the tire pressure warning system)

The tire pressure warning valves and transmitters may not function correctly

when tire chains are fitted.
