Interior features
When the engine switch is turned to IGNITION ON mode, the red indi-
cator light comes on for 2 seconds then turns off. Afterward, the green
indicator light comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage con-
ditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction
(contact your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■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 vehicle’s location and attempts to speak
with the vehicle occupants to assess the level of emergency. If the occu-
pants are unable to communicate, the agent automatically treats the
call as an emergency, contacts the nearest emergency services pro-
vider to describe the situation, and requests that assistance be sent to
the location.

Tires
Check if the treadwear indicators are showing on the tires. Also check the
tires for uneven wear, such as excessive wear on one side of the tread.
Check the spare tire condition and pressure if not rotated.
Replace or rotate tires in accordance with maintenance schedules and
treadwear.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the
tire pressure warning system will not work properly. After driving for about 20 min-
utes, the tire pressure warning light blinks for 1 minute and stays on to indicate a sys-
tem malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has sel-
dom or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■When rotating the tires (vehicles with the tire inflation pressure display function)
Make sure that the engine switch is off. If the tires are rotated while the engine switch
is in IGNITION ON mode, the tire position information will not be updated.
If this accidentally occurs, either turn the engine switch to off and then to IGNITION
ON mode, or initialize the system after checking that the tire pressure is properly
adjusted.

Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands which form
the plies in a tire.

A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a bias-
ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly put into the tire. A tube type
tire has a tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure ( →P. 5 5 4 )
Maximum cold tire inflation pressure ( →P. 5 5 4 )
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
