Important! Read this informatio n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power radio\
transmitter and receiver. It receives and also sends out radio frequency (RF)
signals.
In August 1996, the Federal Commu nications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safe ty standards previously set by the fol-
lowing U.S. and internat ional standards bodies.
●ANSI (American National Stan dards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and governme nt health agencies and industries
reviewed the available body of rese arch to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards.

■Driving mode select switch
The suspension can be switched for improvement in driveability. (P. 291)
■Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differential or wheel bearing), Lexus recommends that you do not
tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to the addi-
tional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.)
●Retighten the fixing bolts of the towing ba ll and bracket after approximately 600 miles
(1000 km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds, passing ve hicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal im mediately 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.
●After the trailer sw aying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not ov erloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.
