STOP” switch to OFF. While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified co ld tire inflation
pressure level. ( P. 8 8 9 )Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times and a message

Maintenance and care
LX570_OM_OM60L21U_(U) ■
Initializing the tire pressure warning system
Initialize the tire pressure warning system with the tire inflation pressure adjusted to
the specified level. ■
If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the ti re inflation pressure to the specified level
and initialize the tire pressure warning system again. ■
When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by your Lexus dealer. ●
When operating the tire pressure warnin g reset switch, the tire pressure warn-
ing light does not blink 3 times and the setting message does not appear on the
multi-information display. ●
After carrying out the initia lization procedure, the tire pressure warning light
blinks for 1 minute then stays on after driving for about 20 minutes.■
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.

Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs. ■
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause da mage to parts of the drive tr ain, as well as dangerous
handling characteristics, which may lead to an accident resulting in death or serious
injury. ●
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear. ●
Do not use tire sizes other th an those recommended by Lexus.●
Do not mix differently constructed tires (radial, bias-belted or bias-ply tires). ●
Do not mix summer, all season and snow tires. ●
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously. ■
When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.
