■ Replacing tires
Make sure that all tires are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC, Trailer Sway Control
and VSC systems will not function cor-
rectly if different tires are installed on the
vehicle.
Contact your Lexus 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 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. (→P.238)
