WARNING
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 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.
If you make no extreme correction with
the steering or brakes, your vehicle and
trailer should stabilize. (
Secondary Collision Brake
■
Do not rely solely upon the Secondary
Collision Brake. 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.
