Lexus NX450H+ (2022 year). Manual in english - page 33

WARNING

●

Do not attach anything to areas such as the doors,
windshield, side windows, front or rear pillars, roof
side rails and assist grips.

●

Do not hang coat hangers or other hard objects on the coat hooks. These items could
become projectiles if the SRS curtain shield airbags deploy, possibly leading to death
or serious injury.

●

If a vinyl cover is attached to the area where the SRS knee airbag deploys, be sure to
remove it.

●

Do not use seat accessories which cover the parts from which the SRS airbags deploy,
as they may interfere with inflation of the SRS airbags. Such accessories may prevent
the SRS airbags from deploying correctly, may disable the system or cause the SRS
airbags to inflate unintentionally, possibly resulting in death or serious injury.

●

Do not strike or apply significant force to the SRS airbag system components, front
doors or their surrounding area. Doing so may cause the SRS airbags to malfunction.

●

Do not touch any components of the SRS airbags immediately after the SRS airbags
have deployed (inflated) as they may be hot.

●

If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.

●

If a part where an SRS airbag is stored is damaged or cracked, have it replaced by
your Lexus dealer.

●

Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger’s weight, which prevents the sensor from detecting the
passenger’s weight properly. As a result, the SRS front airbags for the front passenger’s
seat may not deploy in the event of a collision.

■

Modification and disposal of SRS airbag system components

Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer.
The SRS airbags may malfunction or deploy unintentionally, possibly leading to death or
serious injury.

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"
indicator light is illuminated. If you use the seat belt extender while the "AIR BAG

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.

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 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

•

If coal tar or tree sap is present on the paint surface

•

If dead insects, insect droppings or bird droppings are present on the paint surface

•

After driving in an area contaminated with soot, oily smoke, mine dust, iron powder
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.

●

Wash the vehicle body using a sponge or soft cloth, such as a chamois.

●

For hard-to-remove marks, use car wash soap and rinse thoroughly with water.

●

Wipe away any water.

8-1. Exterior maintenance and care

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.

■

Brake pads and calipers

Rust may form if the vehicle is parked with wet brake pads or disc rotors, causing them
to stick. Before parking the vehicle after it is washed, drive slowly and apply the brakes
several times to dry the parts.

Using an automatic car wash

NOTICE

When using an automatic car wash, move the wiper lever to the off position.
If the wiper lever is in the AUTO position, the wipers may operate unintentionally and the
wiper blades may be damaged.

●

Perform the following before washing your vehicle:

•

Fold the mirrors.

•

Vehicles with power back door:
Turn off the power back door.

Start washing from the front of the vehicle.
