Front passenger occupant classification system precautions

Observe the following precautions regarding the front passenger occupant classification
system. Failure to do so may cause death or serious injury.

●

Wear the seat belt properly.

●

Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.

●

Make sure the "AIR BAG OFF" indicator light is not illuminated when using the seat
belt extender for the front passenger seat. If the "AIR BAG OFF" indicator light is
illuminated, disconnect the extender tongue from the seat belt buckle, and reconnect
the seat belt. Reconnect the seat belt extender after making sure the "AIR BAG ON"

WARNING

OFF" indicator light is illuminated, the SRS airbags for the front passenger will not
activate, which could cause death or serious injury in the event of a collision.

●

Do not apply a heavy load to the front passenger seat or equipment (e.g. seatback
pocket or armrest).

●

Do not put weight on the front passenger seat by putting your hands or feet on the
front passenger seat seatback from the rear passenger seat.

●

Do not let a rear passenger lift the front passenger seat with their feet or press on the
seatback with their legs.

●

Do not put objects under the front passenger seat.

●

Do not recline the front passenger seatback so far that it touches a rear seat. This may
cause the "AIR BAG OFF" indicator light to be illuminated, which indicates that the
SRS airbags for the front passenger will not activate in the event of a severe accident. If
the seatback touches the rear seat, return the seatback to a position where it does not
touch the rear seat. Keep the front passenger seatback as upright as possible when the
vehicle is moving. Reclining the seatback excessively may lessen the effectiveness of
the seat belt system.

●

If an adult sits in the front passenger seat, the "AIR BAG ON" indicator light is
illuminated. If the "AIR BAG OFF" indicator is illuminated, ask the passenger to sit up
straight, well back in the seat, feet on the floor, and with the seat belt worn correctly.
If the "AIR BAG OFF" indicator still remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward.

●

When it is unavoidable to install a forward-facing child restraint system on the front
passenger seat, install the child restraint system on the front passenger seat in the
proper order.

●

Do not modify or remove the front seats.

●

Do not kick the front passenger seat or subject it to severe impact. Otherwise, the SRS
warning light may come on to indicate a malfunction of the front passenger occupant
classification system.
In this case, contact your Lexus dealer immediately.

●

Child restraint systems installed on the rear seat should not contact the front seat-
backs.

●

Do not use a seat accessory, such as a cushion and seat cover, that covers the seat
cushion surface.

●

Do not modify or replace the upholstery of the front seat.

designed to automatically call the response center. The responding agent receives
the vehicle’s location and attempts to speak with the vehicle occupants to assess
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 Connect

Important! Read this information about exposure to radio frequency signals before
using Safety Connect;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 Communications Commission
(FCC) adopted RF exposure guidelines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards previously 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 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 physicians from
universities, and government health agencies and industries reviewed the available
body of research to develop the ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in addition to
those standards.

Washing the vehicle

WARNING

●

When washing the vehicle, do not apply water to the inside of the engine compart-
ment.
If water contacts electrical components, it may cause the vehicle to catch fire.

●

Exhaust gasses cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the exhaust pipes until they have
cooled sufficiently. Touching a hot exhaust pipe can cause burns.

NOTICE

■

To prevent paint deterioration and corrosion of the body and components (wheels,
etc.)

●

Wash the vehicle immediately in the following cases:

•

After driving near the sea coast

•

After driving on salted roads

or chemical substances

•

If the vehicle becomes heavily soiled with dust or mud

•

If liquids such as benzine or gasoline are spilled on the paint surface

●

If the paint is chipped or scratched, have it repaired immediately.

●

To prevent the wheels from corroding, remove any dirt and store in a place with low
humidity when storing the wheels.

■

To prevent damage to the windshield wiper arms

When lifting the wiper arms away from the windshield, pull the driver side wiper arm
upward first, and repeat for the passenger side. When returning the wipers to their
original position, do so from the passenger side first.

Perform cleaning in a manner appropriate to each component and its material.

●

Working from top to bottom, liberally apply water to the vehicle body, wheel
wells and underside of the vehicle to remove any dirt and dust.

●

INFORMATION

■

Self-restoring coat

The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused by a car wash, etc.

●

The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.

●

The restoration time differs depending on the depth of the scratch and outside
temperature.
The restoration time may become shorter when the coating is warmed by applying
warm water.

●

Deep scratches caused by keys, coins, etc., cannot be restored.

●

Do not use waxes that contain abrasives.

■

When using a car wash

If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correction
procedures to wash the vehicle:

●

Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the
vehicle is being washed.
Take care to ensure that the key is not stolen.

●

Set the electronic key to battery-saving mode to disable the smart access system with
push-button start.
