■Tire pressure
●It may take a few minutes to display the tire inflation pressure after the power switch is
turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted.
●“---” may be displayed if the tire position 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.
■Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Some functions can be customized. ( P. 108, 736)
WARNING
■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 dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure that
the vehicle is parked in a place with adequa te ventilation. In a closed area such as a
garage, exhaust gases including harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to dea th or a serious health hazard.
NOTICE
■While setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid system is operating while
setting up the display features.

■Breaking in your new Lexus
To extend the life of the vehicle, observin g the following precautions is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( P. 712)
■Eco-friendly driving
 P. 121
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay re sponse in an emergency, resulting in an accident.
●The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
