WARNING
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 infla-
tion pressure level.
The ABS/Multi Terrain ABS, TRAC/Active TRAC, Trailer Sway Control and VSC sys-
tems will not function correctly 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 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. 195)
