■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on when
you start the engine, this could mean that these systems are not available to help pro-
tect you in an accident, which could result in death or serious injury. Have the vehicle
inspected by your Lexus dealer immediately if this occurs.

■Suspension of the settings display
In the following situations, operation of the settings display will be temporarily sus-
pended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION ON mode. It may also take a few minutes to display the tire infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The drive information data will be reset.
■Liquid crystal display

■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the engine needs to be running during sett ing up the display, ensure that the vehicle
is parked in a place with adequate ventila tion. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■While setting up the display
To prevent battery discharge, ensure that th e engine is running while setting up the dis-
play features.
