WARNING

■

When refueling the vehicle

Observe the following precautions

while refueling the vehicle. Failure

to do so may result in death or

serious injury.

●

After exiting the vehicle and

before opening the fuel door,

touch an unpainted metal sur-

face to discharge any static

electricity. It is important to dis-

charge static electricity before

refueling because sparks result-

ing from static electricity can

cause fuel vapors to ignite while

refueling.

●

Always hold the grips on the

fuel tank cap and turn it slowly

to remove it.

A whooshing sound may be

heard when the fuel tank cap is

loosened. Wait until the sound

cannot be heard before fully

removing the cap. In hot

weather, pressurized fuel may

spray out of the filler neck and

cause injury.

●

Do not allow anyone that has

not discharged static electricity

from their body to come close to

an open fuel tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that

are harmful if inhaled.

●

Do not smoke while refueling

the vehicle.

Doing so may cause the fuel to

ignite and cause a fire.

●

Do not return to the vehicle or

touch any person or object that

is statically charged.

This may cause static electricity

to build up, resulting in a possi-

ble ignition hazard.

■

When refueling

Observe the following precautions

to prevent fuel overflowing from

the fuel tank:

●

Securely insert the fuel nozzle

into the fuel filler neck.

●

Stop filling the tank after the fuel

nozzle automatically clicks off.

●

The driver is solely responsible

for safe driving. Always drive

safely, taking care to observe

your surroundings.

Do not use the pre-collision sys-

tem instead of normal braking

operations under any circum-

stances. This system will not

prevent collisions or lessen col-

lision damage or injury in every

situation. Do not overly rely on

this system. Failure to do so

may lead to an accident, result-

WARNING

●

Although this system is

designed to help avoid a colli-

sion or help reduce the impact

of the collision, its effectiveness

may change according to vari-

ous conditions, therefore the

system may not always be able

to achieve the same level of

performance.

Read the following conditions

carefully. Do not overly rely on

this system and always drive

carefully.

• Conditions under which the sys-

tem may operate even if there is

no possibility of a collision:

P.242

• Conditions under which the sys-

tem may not operate properly:

P.243

●

Do not attempt to test the oper-

ation of the pre-collision system

yourself.

Depending on the objects used

for testing (dummies, card-

board objects imitating detect-

able objects, etc.), the system

may not operate properly, possi-

bly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking

function is operating, a large

amount of braking force will be

applied.

●

If the vehicle is stopped by the

operation of the pre-collision

braking function, the pre-colli-

sion braking function operation

will be canceled after approxi-

mately 2 seconds. Depress the

brake pedal as necessary.

●

The pre-collision braking func-

tion may not operate if certain

operations are performed by the

driver. If the accelerator pedal is

being depressed strongly or the

steering wheel is being turned,

the system may determine that

the driver is taking evasive

action and possibly prevent the

pre-collision braking function

from operating.

●

In some situations, while the

pre-collision braking function is

operating, operation of the func-

tion may be canceled if the

accelerator pedal is depressed

strongly or the steering wheel is

turned and the system deter-

mines that the driver is taking

evasive action.

●

If the brake pedal is being

depressed, the system may

determine that the driver is tak-

ing evasive action and possibly

delay the operation timing of the

pre-collision braking function.

■

Emergency steering assist

●

As emergency steering assist

operation will be canceled when

the system determines that lane

departure prevention function

has been completed.

●

Emergency steering assist may

not operate or may be cancel in

the following cases as the sys-

tem may determine the driver is

taking actions.

• If the accelerator pedal is being

depressed strongly, the steering

wheel is being operated sharply,

the brake pedal is being

depressed or the turn signal

lever is being operated. In this

case, the system may deter-

mine that the driver is taking

evasive action and the emer-

gency steering assist may not

WARNING

• In some situations, while the

emergency steering assist is

operating, operation of the func-

tion may be canceled if the

accelerator pedal is depressed

strongly, the steering wheel is

operated sharply or the brake

pedal is being depressed and

the system determines that the

driver is taking evasive action.

• When the emergency steering

assist is operating, if the steer-

ing wheel is held firmly or is

operated in the opposite direc-

tion to that which the system is

generating torque, the function

may be canceled.

■

When to disable the pre-colli-

sion system

In the following situations, disable

the system, as it may not operate

properly, possibly leading to an

accident resulting in death or seri-

ous injury:

●

When the vehicle is being towed

●

When your vehicle is towing

another vehicle

●

When transporting the vehicle

via truck, boat, train or similar

means of transportation

●

When the vehicle is raised on a

lift with the engine running and

the tires are allowed to rotate

freely

●

The driver must always assume

full responsibility for driving

safely by paying careful atten-

tion to the surrounding condi-

tions and operating the steering

wheel to correct the path of the

vehicle. Also, the driver must

take adequate breaks when

fatigued, such as from driving

for a long period of time.

●

Failure to perform appropriate

driving operations and pay care-

ful attention may lead to an

accident, resulting in death or

serious injury.

WARNING

■

Before using dynamic radar

cruise control with full-speed

range

●

Driving safely is the sole

responsibility of the driver. Do

not rely solely on the system,

and drive safely by always pay-

ing careful attention to your sur-

roundings.

●

The dynamic radar cruise con-

trol with full-speed range pro-

vides driving assistance to

reduce the driver’s burden.

However, there are limitations to

the assistance provided.

Read the following conditions

carefully. Do not overly rely on

this system and always drive

carefully.

• When the sensor may not be

correctly detecting the vehicle

ahead:

WARNING

• Conditions under which the

vehicle-to-vehicle distance con-

trol mode may not function cor-

rectly:



P.268

●

Set the speed appropriately

depending on the speed limit,

traffic flow, road conditions,

weather conditions, etc. The

driver is responsible for check-

ing the set speed.

●

Even when the system is func-

tioning normally, the condition of

the preceding vehicle as

detected by the system may dif-

fer from the condition observed

by the driver. Therefore, the

driver must always remain alert,

assess the danger of each situ-

ation and drive safely. Relying

solely on this system or assum-

ing the system ensures safety

while driving can lead to an

accident, resulting in death or

serious injury.

●

Switch the dynamic radar cruise

control with full-speed range

setting to off, using the cruise

control main switch when not in

use.

■

Cautions regarding the driv-

ing assist systems

Observe the following precau-

tions, as there are limitations to

the assistance provided by the

system. Failure to do so may

cause an accident resulting in

death or serious injury.

●

Assisting the driver to measure

following distance

The dynamic radar cruise control

with full-speed range is only

intended to help the driver in

determining the following distance

between the driver’s own vehicle

and a designated vehicle traveling

ahead. It is not a mechanism that

allows careless or inattentive driv-

ing, and it is not a system that can

assist the driver in low-visibility

conditions.

It is still necessary for driver to

pay close attention to the vehi-

cle’s surroundings.

●

Assisting the driver to judge

proper following distance

The dynamic radar cruise control

with full-speed range determines

whether the following distance

between the driver’s own vehicle

and a designated vehicle traveling

ahead is within a set range. It is

not capable of making any other

type of judgement. Therefore, it is

absolutely necessary for the

driver to remain vigilant and to

determine whether or not there is

a possibility of danger in any

given situation.

●

Assisting the driver to operate

the vehicle

The dynamic radar cruise control

with full-speed range does not

include functions which will pre-

vent or avoid collisions with vehi-

cles ahead of your vehicle.

Therefore, if there is ever any

possibility of danger, the driver

must take immediate and direct

control of the vehicle and act

appropriately in order to ensure

the safety of all involved.

Do not use dynamic radar cruise

control with full-speed range in

any of the following situations.

Doing so may result in inappropri-

ate speed control and could

cause an accident resulting in

death or serious injury.

●

Roads where there are pedes-

HIGHLANDER_U

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehi-
cle-to-vehicle following distance, and operates to maintain a suitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears

When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not performed, system
control continues to keep your vehicle stopped.

When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehicle will accel-
erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehicle is driven to a
region where the overtaking lane is on a different side from where the vehi-
cle is normally driven, the vehicle may accelerate when the turn signal lever
is operated in the opposite direction to the overtaking lane (e.g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
vehicle may accelerate when the right turn signal is activated).

Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed

The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
