CAUTION
■SRS airbag precautions
●If the vinyl cover is put on the area where the SRS knee airbag will deploy, be sure
to remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 60. Doing so ca n cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbag has deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
●Do not attach anything to or lean anything
against areas such as the dashboard, steer-
ing wheel pad or lower portion of the
instrument panel. These items can become
projectiles when SRS driver, front passen-
ger and knee airbags deploy.
●Do not attach anything to areas such as the
door, windshield glass, side door glass,
front and rear pillars, roof side rail or assist
grip.
●Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and seri-
ously injure or kill you, should the SRS cur-
tain shield airbag deploy.

When driving
CAUTION
■When driving the vehicle
●Do not under any circumstances shift the shift lever to “P”, “R” or “N” while the
vehicle is moving.
Doing so can cause significant damage to the transmission and may result in a
loss of vehicle control.
●Do not shift the shift lever to “N” while the vehicle is moving. 
Doing so may cause the engine brake not to operate properly and lead to an
accident.
●Do not turn the engine off while driving. 
The power steering and brake actuator (GS430) or brake booster (GS350) will
not operate properly if the engine is not running.
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill. 
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( P. 1 0 2 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving. 
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.

2-1. Driving procedures
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 (GS430): 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 recom-
mends that you also have the th ickness 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.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds.
●The vehicle will behave abnormally.
Replace a flat tire with a new one. ( P. 4 76 )

CAUTION
■When the radar sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctl y detect these types of vehicles, the prox-
imity alarm ( P. 466) will not be activated, and an accident may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (tra ilers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly

2-4. Using other driving systems
Intuitive parking assist (if equipped)
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the mult i-information display, the touch screen,
and warning beeps.

The system may be used at speeds less than about 6 mph (10 km/h).
■ Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, an d one in each corner of the bumper,
to detect obstacles in those areas. 
The dual sensors detect obstacles ahea d of the v
ehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. (25 cm) of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.
