NOTICE
■Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehicle interior
or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline, alkaline oracidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●Do not use polish wax or polish cleaner. The instrument panel’s or other interior part’s
painted surface may be damaged.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces:
●Remove any dust or dirt from leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended periods of time. Park the
vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, as they
may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into contact
with electrical components such as the audio system above or under the floor of the
vehicle. Water may also cause the body to rust.

■Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily drops, the
electric power steering system warning light may come on and the warning buzzer may
sound.
■When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check that the tire infla-
tion pressure is at the specifie d level and carry out initialization.
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
■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 and tire inflation pressure changes caused by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning light
will not turn off even though the flat tire has been replaced with the spare tire.
Vehicles with full-size spare tire: The spare tire is also equipped with a tire pressure warn-
ing valve and transmitter. The tire pressure warn ing light will turn on if the tire inflation
pressure of the spare tire is low. If a tire go es flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
→ P. 4 7 0
■If the tire pressure warning light frequently comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute when the
engine switch is turned to IGNITION ON mode, have it checked by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an audio sound.

cle distance decreases:
●When your vehicle and the vehicle ahead are traveling at the same speed or the vehicle
ahead is traveling more quickly than your vehicle
●When the vehicle ahead is traveling at a very low speed
●Immediately after cruise control speed is set
●At the instant the accelerator pedal is depressed
■Open door warning message (GS350/GS200t only)

closed, even if the engine switch is turned off. However, approximately 20 minutes after a

■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle is not
in use, due to natural discharge and the draining effects of certain electrical appliances. If
the vehicle is left for a long time, the battery may discharge, and the engine may be
unable to start. (The battery recharges automatically during driving.)
■When recharging or replacing the battery
●In some cases, it may not be possible to un lock the doors using the smart entry & start
system when the battery is discharged. Use the wireless remote control or the mechan-
ical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but will
start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-
nected, the system will return to the mode it was in before the battery was discharged.
Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery discharged, be
especially careful when reconnecting the battery.
