CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it
may become difficult to stop the vehicle, leading to an accident, or leading to
death or a serious injury.
When installing the driver’s floor mat
Do not use floor mats designed for other models or different model year
vehicles, even if they are Lexus Genuine floor mats.
Only use floor mats designed for the driver’s seat.
Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
Do not use two or more floor mats on top of each other.
Do not place the floor mat bottom-side up or upside-down.
Before driving
Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
With the engine stopped and the shift
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.

For safety and security
GS350/250_EE (OM30C36E)The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. As
the airbags deploy, a chemical reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the
occupants.
CAUTION
SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.)
of inflation, placing yourself 250 mm (10 in.) from your driver airbag
provides you with a clear margin of safety. This distance is measured
from the center of the steering wheel to your breastbone. If you sit less
than 250 mm (10 in.) away now, you can change your driving position in
several ways:
• Move your seat to the rear as far as you can while still reaching the ped-
als comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm
(10 in.) distance, even with the driver seat all the way forward, simply
by reclining the back of the seat somewhat. If reclining the back of your
seat makes it hard to see the road, raise yourself by using a firm, non-
slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the
airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.

GS350/250_EE (OM30C36E)
CAUTION
SRS airbag precautions
The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too
small to use a seat belt should be properly secured using a child restraint
system. Lexus strongly recommends that all infants and children be
placed in the rear seats of the vehicle and properly restrained. The rear
seats are safer for infants and children than the front passenger seat. (P.
59)
Do not sit on the edge of the seat or lean
against the dashboard.
Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
Do not allow the front seat occupants to
hold items on their knees.
Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.

If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, the glove box, parts of the front and rear pillars, and roof
side rails may be hot for several minutes. The airbag itself may also be hot.
The windshield may crack.
SRS airbag deployment conditions (SRS front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 20
- 30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not
move or deform).
However, this threshold velocity will be considerably higher in the follow-
ing situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
SRS airbag deployment conditions (SRS side and curtain shield airbags)
The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 1500 kg [3300 lb.] vehi-
cle colliding with the vehicle cabin from a direction perpendicular to the
vehicle orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
The SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.

891-2. Theft deterrent system

GS350/250_EE (OM30C36E)
For safety and security
The intrusion sensor detects intruders or movement in the vehi-
cle.
The tilt sensor detects changes in vehicle inclination, such as
when the vehicle is towed away. (if equipped)
This system is designed to deter and prevent vehicle theft but does
not guarantee absolute security against all intrusions.
Setting the intrusion sensor and tilt sensor
The intrusion sensor and tilt sensor will be set automatically
when the alarm is set. (P. 86)
Canceling the intrusion sensor and tilt sensor
If you are leaving pets or other moving things inside the vehicle,
make sure to stop the intrusion sensor and tilt sensor before set-
ting the alarm, as they will respond to movement inside the vehi-
cle.
Turn the engine switch off.
Press the intrusion sensor
and tilt sensor cancel
switch.
A message will be shown on the
multi-information display in the
instrument cluster.
Press the switch again to re-
enable the intrusion sensor and
tilt sensor.

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
characteristic 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.
857)
CAUTION
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information dis-
play 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 down-
shift again, causing 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.

The head-up display may seem dark and hard to see when viewed through
sunglasses, especially polarized sunglasses.
Adjust the brightness of the head-up display or remove your sunglasses.
When the head-up display is turned off, it will remain off even if the engine
switch is turned to IGNITION ON mode after the engine switch has been
turned off.
When the battery is disconnected
The customize settings of the head-up display will be reset.
CAUTION
Before using the head-up display
Check that the position and brightness of the head-up display image does
not interfere with safe driving. Incorrect adjustment of the image’s position
or brightness may obstruct the driver’s view and lead to an accident, result-
ing in death or serious injury.
