■Tire inflation pressure (if equipped)
●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 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 temperature. The displayed values may also be
different 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 character-
istic of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Setting of available languages can be changed. (Customizable features: →P. 6 5 2 )
CAUTION
■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.
■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
■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)
■Tire information
●Increase 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 )
●Increase 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.
■Trailer lights
●Please 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.
●Check 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.
■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).
■Safety checks before towing
●Check 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 )
●Ensure that the trailer load is secure.
●Supplementary 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.
■Maintenance
●Maintenance 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.
●Retighten all bolts securing the hitching ball and bracket after towing for approxi-
mately 1000 km (600 miles).

■After the vehicle has been parked in the sun
The LKA system functions may not be available and a warning message (→P. 5 6 3 )
will be displayed for a while after driving has started. In such cases, turn the LKA sys-
tem off and turn it on again after normal temperature returns. When the temperature
in the cabin decreases and the temperature around the camera sensor ( →P. 3 0 5 )
becomes suitable for its operation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure warning
will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lanes are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Raised pavement marker” or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens
●When driving on roads that are branching or merging
