Driving

WARNING

• Conditions under which the system 

may not operate properly: 



P.172

●

Do not attempt to test the operation of 

the pre-collision system yourself.

Depending on the objects used for 

testing (dummies, cardboard objects 

imitating detectable objects, etc.), the 

system may not operate properly, pos-

sibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking func-

tion is operating, a large amount of 

braking force will be applied.

●

If the vehicle is stopped by the opera-

tion of the pre-collision braking func-

tion, the pre-collision braking function 

operation will be canceled after 

approximately 2 seconds. Depress the 

brake pedal as necessary.

●

The pre-collision braking function may 

not operate if certain operations are 

performed by the driver. If the acceler-

ator pedal is being depressed strongly 

or the steering wheel is being turned, 

the system may determine that the 

driver is taking evasive action and pos-

sibly prevent the pre-collision braking 

function from operating.

●

In some situations, while the pre-colli-

sion braking function is operating, 

operation of the function may be can-

celed 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 taking evasive action and pos-

sibly delay the operation timing of the 

pre-collision braking function.

■

Emergency steering assist

●

As emergency steering assist opera-

tion will be canceled when the system 

determines that lane departure pre-

vention function has been completed.

●

Emergency steering assist may not 

operate or may be canceled in the fol-

lowing cases as the system may deter-

mine 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 determine that 

the driver is taking evasive action and 

the emergency steering assist may not 

operate.

• In some situations, while the emer-

gency steering assist is operating, 

operation of the function may be can-

celed 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 steering wheel is held 

firmly or is operated in the opposite 

direction to that which the system is 

generating torque, the function may be 

canceled.

■

When to disable the pre-collision sys-

tem

In the following situations, disable the 

system, as it may not operate properly, 

possibly leading to an accident resulting 

in death or serious 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
