■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle wh en operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected corr ectly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not function.)
■Note for the smart access system with push-button start
●Even when the electronic key is within the effective range (detection areas), the
system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear bumper center when the trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in
the glove box when the engine is started or “ENGINE START STOP” switch
modes are changed.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●Even if the electronic key is not inside th e vehicle, it may be possible to start the
engine if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash when the electronic key is within the effective
range. (The doors will automatically be locked after approximately 60 seconds
if the doors are not opened and closed.)

CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift lever or
depress the accelerator pedal, which could cause an accident or fire due to engine
overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust
gases may collect and enter th e vehicle, leading to death or a serious health hazard.
■When braking the vehicle
●When the brakes are wet, drive more cautiously. 
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle.
●If the brake actuator (GS460) or brake booster (GS350) does not operate, do
not follow other vehicles closely and avoi d downhill or sharp turns that require
making. 
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if turning the engine off. 
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 3 (GS460) or 2 (GS350) individual hydraulic sys-
tems: If one of the systems fails, the other will still operate. In this case, the brake
pedal should be depressed more firmly th an usual and braking distance becomes
longer. 
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
■If the vehicle becomes stuc k or bogged (4WD models)
Do not spin the wheels recklessly when any of the tires is up in the air, or stuck in
sand or mud, etc. This may damage the drive system components or propel the
vehicle forward (or in another direction) and cause an accident.

NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together
to hold the vehicle on a hill.
■When parking the vehicle
Always put the shift lever in “P”. Failure to do so may cause the vehicle to move or
the vehicle may accelerate suddenly if the accelerator pedal is accidentally
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time. 
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced
front braking power. As a result, the discs may wear more quickly than conventional
brake discs. Therefore, when replacing the brake pads, Lexus recommends that you
also have the thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.

CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not press the accelera-
tor pedal while starting the engine under any circumstances. 
Doing so may cause an accident resu lting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, push and
hold the “ENGINE START STOP” switch for more than 3 seconds. 
However, do not touch the “ENGINE START STOP” switch while driving except in
an emergency. If the engine stops while the vehicle is being driven, this could lead to
an unexpected accident.
NOTICE
■To prevent 12 volt battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNITION
ON mode for long periods if the engine is not running.
■When starting the engine
●Do not race the engine.
●If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
