The main SRS airbag system components are shown above. The SRS airbag sys-
tem is controlled by the airbag sensor assembly. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.
WARNING
■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 seri-
ous injury especially if the driv er 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 o f 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:

2123-4. Adjusting the steering wheel and mirrors
GS350_200t_GS F_OM_OM30F83E_(EE)
■Using the switch
Press the switch to fold the mirrors.
Press it again to extend them to the
original position.
■Setting automatic mode
Automatic mode allows the folding or extending of the mirrors to be linked to
locking/unlocking of the doors.
Press the “AUTO” switch to set auto-
matic mode.The indicator will come on.
Pressing the switch once more will
return to manual mode.
When either “L” or “R” of the mirror select switch is selected, the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground. To disable this function, select neither
“L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired positio n.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time. The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shift lever in othe r than R). Therefore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is changed, readjust the angle in reversing.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as
this may restrain the engine output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake, and shift the shift lever to 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 an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possi ble to avoid damaging
the wheels, underside of the vehicle, etc.
●GS200t: Make sure to idle the engine immediately after high-load driving. Stop the
engine only after the turbocharger has cooled down. ( P. 225)
Failure to do so may cause damage to the turbocharger.
■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 depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 557, 573)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
any authorized Lexus retailer or Lexus auth orized repairer, or any reliable repairer
check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

2384-1. Before driving
GS350_200t_GS F_OM_OM30F83E_(EE)
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and ensure that
the vehicle-to-vehicle distance is sufficient before executing lane change s.
■Transmission information
To maintain engine braking efficiency, when using engine braking, when driv-
ing on a long steep downgrade, do not use the transmission in D . If in the M
mode, the transmission shift range position must be in 4 or lower. ( P. 249)
■If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures exceeding 30 C (85 F) may result in the engine overheating. If the engine coolant tem-
perature gauge indicates that the engine is overheating, turn the air condition-
ing off immediately, leave the road and stop the vehicle in a safe place. (  P. 602)
■When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and trailer.
Firmly set the parking brake and shift the shift lever to P.
WARNING
Follow all the instructions described in this se ction. Failure to do so could cause an acci-
dent resulting in death or serious injury.
■Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded. ( P. 234)
■To avoid accident or injury
●Do not tow a trailer when the compact spare tire is installed on your vehicle.
●Do not tow a trailer when the tire installed is repaired with the emergency tire punc-
ture repair kit.
●Do not use cruise control (if equipped), dynamic radar cruise control (if equipped) or
dynamic radar cruise control with full-speed range (if equipped) when trailer towing.
■Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
■Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while descending
steep or long downhill grades.
■Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake ov erheating or reduce braking effects.

●Side road speed signs may be detected and di splayed (if positioned in sight of the cam-
era sensor) while the vehicle is traveling on the main road.
●Roundabout exit road speed signs may be detected and displayed (if positioned in sight
of the camera sensor) while traveling on a roundabout.
●On some models: The speed information displayed on the meter and t hat displayed on
the navigation system may be different due to the navigation system using map data.
■When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set un it of the meter, it is necessary to change
the set unit of the meter. Adjust the set unit of the meter to the speed unit of signs in the
current location. ( P. 641)
■Turning the system on/off
■Speed limit sign display
If the engine switch was last turned off while a speed limit sign was displayed on the multi-
information display, the same sign displays again when the engine switch is turned to
IGNITION ON mode.
