Parking Support Brake function (static objects)

*

If the sensors detect a static object, such as a wall, in the travelling direction of 
the vehicle and the system determines that a collision may occur due to the 
vehicle suddenly moving forward due to an accidental accelerator pedal oper-
ation, the vehicle moving the unintended direction due to the wrong shift lever 
position, or while parking or traveling at low speeds, the system will operate to 
lessen the impact with the detected static object and reduce the resulting 
damage.

Trailer Sway Control precaution

The Trailer Sway Control system is not 

able to reduce trailer sway in all situa-

tions. Depending on many factors such 

as the conditions of the vehicle, trailer, 

road surface and driving environment, 

the Trailer Sway Control system may not 

be effective. Refer to your trailer owner’s 

manual for information on how to tow 

your trailer properly.

■

If trailer sway occurs

Observe the following precautions.

Failing to do so may cause death or seri-

ous injury.

●

Firmly grip the steering wheel. Steer 

straight ahead. Do not try to control 

trailer sway by turning the steering 

wheel.

●

Begin releasing the accelerator pedal 

immediately but very gradually to 

reduce speed.

Do not increase speed. Do not apply 

vehicle brakes.
