■Toyota Safety Sense 3.0

The Toyota Safety Sense 3.0

operates under the assumption

that the driver will drive safely,

and is designed to help reduce

the impact to the occupants in a

collision and assist the driver

under normal driving conditions.

As there is a limit to the degree of

recognition accuracy and control

performance that this system can

provide, do not overly rely on this

system. The driver is solely

●When the vehicle is tilted due to

being overloaded or having a

flat tire

responsible for paying attention to

the vehicle’s surroundings and

driving safely.

●When driving at extremely high

speeds

■For safe use

●Do not overly rely on this sys-

tem. The driver is solely respon-

sible for paying attention to the

vehicle’s surroundings and driv-

ing safely. This system may not

operate in all situations and pro-

vided assistance is limited.

Over-reliance on this system to

drive the vehicle safely may

lead to an accident resulting in

death or serious injury.

●When towing another vehicle

●When the vehicle is being trans-

ported by a truck, ship, train,

etc.

●When the vehicle is raised on a

lift and the tires are allowed to

rotate freely

●When inspecting the vehicle

using a drum tester such as a

chassis dynamometer or speed-

ometer tester, or when using an

on vehicle wheel balancer

●Do not attempt to test the oper-

ation of the system, as it may

not operate properly, possibly

leading to an accident.

●When the vehicle is driven in a

sporty manner or off-road

●When using an automatic car

WARNING

sensors.

■To prevent malfunction of the

radar sensors

●Do not modify or paint the radar

sensors or radar sensor cover,

or replace them with anything

other than Toyota genuine parts.

Observe the following precau-

tions. Failure to do so may lead to

a radar sensor not operating prop-

erly, possibly leading to an acci-

dent resulting in death or serious

injury.

●In the following situations, recal-

ibration of the radar sensors will

be necessary. For details, con-

tact by your Toyota dealer.

●Keep the radar sensors and

radar sensor covers clean at all

times.

• When a radar sensor is

removed and installed, or

replaced

Clean the front of a radar sensor

or the front or back of a radar sen-

sor cover if it is dirty or covered

with water droplets, snow, etc.

• When the front bumper or the

front grille has been replaced

■Radar sensor cover with a

heater

When cleaning the radar sensor

and radar sensor cover, use a soft

cloth to remove dirt so as to not

damage them.

When the system determines that

snow may pile up over the radar

sensor cover, the heater will oper-

ate automatically. If the area

around the radar sensor cover is

to be touched, such as during

cleaning, make sure that the radar

sensor cover is cool enough to

prevent burns.
