Maintenance and care
Initializing the tire pressure warning systemThe tire pressure warning system must be initialized when the tire infla-
tion pressure is changed (such as when changing traveling speed).
When the tire pressure warning system is initialized, the current tire infla-
tion pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the ignition switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 366)
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 ignition switch to the “ON” position.
Press and hold the tire pressure
warning reset switch until the tire
pressure warning light flashes
slowly 3 times.
Wait for a few minutes with th e ignition switch in the “ON” posi-
tion and then turn the ignition switch off.

If initialization is performed, adjust the tire 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 warning reset switch, the tire pressure warning
light does not flash 3 times.
●After carrying out the initialization procedure, the tire pressure warning light
flashes for 1 minute then stays on after driving for 20 minutes.

5-2. Steps to take in an emergency
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after taking several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
■Electric power steering system warning light
When the battery is low or when the voltage drops temporarily, the electric power
steering system warnin g light may come on.
■Passenger detection sensor and passenger seat belt reminder
●If luggage is placed on the passenger seat, the passenger detection sensor may
cause the warning light to flash even if a passenger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light. After
the tire inflation pressure is adjusted, it may take a few minutes for the tire pressure
warning light to go off.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks or tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few min-
utes).
