WARNING
■ When the TRAC / VSC / Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRAC / VSC / Trailer Sway Control systems off unless necessary.
Trailer Sway Control is part of the VSC system and will not operate if VSC is turned off or experiences
a malfunction.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recommended tire inflation pressure level. The ABS, TRAC Trailer Sway Control and VSC systems will not function correctly if different tires are installed on the vehicle. Contact your SUBARU dealer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a system to
malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations. 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 serious 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.
If you make no extreme correction with the steering or brakes, your vehicle and trailer should stabilize.( �P. 228)
■ Secondary Collision Brake( Secondary collision reduction at the time of a frontal
collision)
Do not rely solely upon the Secondary Collision Brake( Secondary collision reduction at the time of a frontal collision). This system
is designed to help reduce the possibility of further damage due to a secondary collision, however, that effect changes according to various conditions. Overly relying on the system may result in death or serious injury.
