Interior features
■Outside temperature display
●The temperature display shows temperatures within the range of -40°F (-40°C)
and 122°F (50°C).
●In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
• When the vehicle is stopped, or moving at low speeds (less than 15 mph [25
km/h])
• When the outside temperature has chan ged suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “--” or “E” is displayed, the system may be malfunctioning. Take your vehi-
cle to your Lexus dealer.
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outs ide air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is stopped.

Safety information for Safety ConnectImportant! Read this information before using Safety Connect.
■ Exposure to radio frequency signals
The Safety Connect sy stem installed in your ve hicle is a low-power
radio transmitter and receiver. It receives and also sends out radio fre-
quency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels fo r mobile wireless
phones. Those guidelines are consistent with the safety standards pre-
viously set by the following U.S. and international standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on co mprehensive and periodic evalua-
tions of the relevant scientific literature. Over 120 scientists, engineers,
and physicians from universities, an d government health agencies and
industries reviewed the available body of research to develop the
ANSI Standard (C95.1).
The design of Safety Connect co mplies with the FCC guidelines in
addition to those standards.
