Rear sunshade
■Reverse operation feature
This function will become operational after the vehicle has been driven at 9 mph (15
km/h) or more with the rear sunshade in the raised position.
To ensure adequate rear visibility, the sunshade automatically lowers when the shift
lever is shifted to R and the function is in an operational condition.
However, the rear sunshade is raised again if either of the following occurs:
●The switch is pressed again.
●The shift lever is shifted out of R, and the vehicle reaches a speed of 9 mph (15
km/h).
If the engine is turned off when the rear sunshade has been lowered due to the
reverse operation feature, it will not be raised even when the engine is turned on
again and the vehicle reaches a speed of 9 mph (15 km/h). To raise the sunshade
again, press the switch.
■The rear sunshade can be used when
The “ENGINE START STOP” switch is in IGNITION ON mode.
The rear sunshade can be raised and lowered by operating the switch

Use only floor mats designed specifically for vehicles of the same model
and model year as your vehicle. Fix them securely in plac e onto the carpet.
Fix the floor mat in place using
the retaining hooks (clips) pro-
vided.
For details, refer to the floor mat
retention clip installation
instructions supplied with the

●Check that the floor mat is securely fixed in
the right place with all the provided retain-
ing hooks (clips). Be especially careful to

Safety Connect services
■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicl e’s location and attempts to speak
with the vehicle occupants to asse ss the level of emergency. If the
occupants are unable to communicate, the agent automatically treats
the call as an emergency, contacts the nearest emergency services
provider to describe the situation, and requests that assistance be sent
to the location.

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 vehicle 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 Radiation 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.
