For safety and security
â– Tilt sensor detection considerations (if equipped)
The sensor may trigger the alarm in the following situations:
â—ŹThe vehicle is transported by a ferry, trailer, train, etc.
â—ŹThe vehicle is parked in a parking garage.
â—ŹThe vehicle is inside a car wash that moves the vehicle.
â—ŹAny of the tires loses air pressure.
â—ŹThe vehicle is jacked up.
â—ŹAn earthquake occurs or the road caves in.
NOTICE
â– To ensure the intrusion sensor function correctly
â—ŹInstalling accessories other than genuine Lexus parts or leaving objects between
the driver’s seat and front passenger’s seat may reduce the detection perfor-
mance.
â—ŹTo ensure that the sensors operate prop-
erly, do not touch or cover them.
â—ŹDo not spray air fresheners or other prod-
ucts directly into the sensor holes.

â– Tire inflation pressure (if equipped)
Outside temperature, average fuel
consumption after refueling or driv-
ing range can be selected and dis-
played.
If displayed on the drive monitor,
other trip information or warning
messages can be displayed simulta-
neously.
For display and selection proce-
dures, follow the “Setting up the dis-
plays”.
The information displayed on the drive

â– Tire inflation pressure (if equipped)
â—ŹIt 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 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.
â—ŹTire inflation pressure changes with temperature. The displayed values may also be
different from the values measured using a tire pressure gauge.
â– Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is character-
istic of liquid crystal displays, and there is no problem continuing to use the display.
â– Customization
Setting of available languages can be changed. (Customizable features: →P. 6 5 2 )
CAUTION
â– The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the 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 cause the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
â– Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that the
vehicle is parked in a place with adequate 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 death or a serious health hazard.
NOTICE
â– During setting up the display
To prevent battery discharge, ensure that the engine is running while setting up the
display features.

2324-1. Before driving
GS350_250_OM_OM30E16E_(EE)
â– Tire information
â—ŹIncrease the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater
than the recommended value when towing. ( →P. 6 4 5 )
â—ŹIncrease the air pressure of the trailer tires in accordance with the total trailer
weight and according to the values recommended by the manufacturer of your
trailer.
â– Trailer lights
â—ŹPlease consult at any authorized dealer or repairer, or another duly qualified and
equipped professional when installing trailer lights, as incorrect installation may
cause damage to the vehicle’s lights. Please take care to comply with your state’s
laws when installing trailer lights.
â—ŹCheck that the turn signal lights and stoplights are operating correctly every time
you hitch up the trailer. Directly wiring up to your vehicle may damage the electrical
system and stop the lights from functioning correctly.
â– Break-in schedule
Lexus recommends that vehicles fitted with new power train components should not
be used for towing trailers for the first 800 km (500 miles).
â– Safety checks before towing
â—ŹCheck that the maximum load limit for the towing hitch/bracket and hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the load
exerted on the vehicle. Also make sure that the total load exerted on the vehicle is
within the range of the weight limits. ( →P. 2 2 8 )
â—ŹEnsure that the trailer load is secure.
â—ŹSupplementary outside rear view mirrors should be added to the vehicle if the traf-
fic behind cannot be clearly seen with standard mirrors. Adjust the extending arms
of these mirrors on both sides of the vehicle so that they always provide maximum
visibility of the road behind.
â– Maintenance
â—ŹMaintenance must be performed more frequently when using the vehicle for tow-
ing due to the greater weight burden placed on the vehicle compared to normal
driving.
â—ŹRetighten all bolts securing the hitching ball and bracket after towing for approxi-
mately 1000 km (600 miles).
