CAUTION
When adjusting the seat position
Take care when adjusting the seat position to ensure that other passengers
are not injured by the moving seat.
Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.
Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.

CAUTION
Operating the front passenger’s seat from the driver’s seat (if equipped)
Do not operate the front passenger’s seat when a passenger is seated in it. In
addition, do not let anyone sit down in the front passenger’s seat while the
seat is being operated. The front passenger may catch their legs between the
instrument panel and seat, resulting in injury.
When adjusting the seat positions or the calf support (if equipped)
Make sure to leave enough space around the feet so they do not get stuck.
When using the calf support (if equipped)
Do not operate the calf support when the vehicle is moving.
Failure to do so may cause death or serious injury in the event of sudden
braking or a collision.
Do not sit on the calf support of the passenger seat.
Doing so may cause seat belts to be worn improperly, which may lead to
serious injury or death in the event of sudden braking or a collision.
Do not step on the calf support.
Doing so could damage the calf support, or could cause you to seriously
injure yourself by falling over.
Stow the calf support when you get in or out of the vehicle or when the
calf support is not in use to avoid stumbling over it.
Do not allow anyone to put their hands or feet under the passenger seat
when stowing the calf support.

Operation of each component
GS350/250_EE (OM30C36E)
When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memo-
rized position but stop slightly beforehand to allow easy access to the vehi-
cle.
Turning the engine switch to ACCESSORY or IGNITION ON mode, or fas-
tening the driver’s seat belt moves the seat fully into the memorized position.
Operating the driving position memory after turning the engine switch off
Driver’s seat:
Memorized seat positions can be activated up to 180 seconds after the
driver’s door is opened and another 60 seconds after it is closed again. Mem-
orized steering wheel position can be activated by pressing the engine switch.
Front passenger’s seat:
Memorized positions can be activated up to 180 seconds after the front pas-
senger’s door is opened by pressing button “1”, “2” or “3”.
Correct seat position
When the seat is in the most forward or most backward position, and the seat
is being moved in those directions, the system may not correctly recognize
the current position and the memorized position will not be correctly
recalled.
The auto away function for exiting the driver’s seat
If the seat is already close to the rearmost position, the auto away function
may not operate when the driver exits the vehicle.
Customization
The distance that the driver’s seat moves backward during the auto away
function can be changed. (Customizable features: P. 855)
CAUTION
Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear
passenger or squeeze your body against the steering wheel.

PCS (Pre-Crash Safety system)
Pre-crash seat belts (front seat only)
If the pre-crash sensor detects that a collision is unavoidable, the
pre-crash safety system will retract the seat belt before the colli-
sion occurs.
The same will happen if the driver makes an emergency braking
or loses control of the vehicle. (P. 40)
Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the
brake pedal is depressed.
Pre-crash braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and
buzzer. If the system determines that a collision is unavoidable,
the brakes are automatically applied to reduce the collision
speed.

: If equipped
When the radar sensor detects that a frontal collision is highly
likely or even unavoidable, safety systems such as the brakes and
seat belts are automatically engaged to lessen impact as well as
vehicle damage.
The pre-crash safety system can be turned on and off as necessary
by operating the switch. (P. 344)
