CAUTION
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting 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,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. (P. 739)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering
or braking control, but the power assist to these systems will be lost. This
will make it more difficult to steer and brake, so you should pull over and
stop the vehicle as soon as it is safe to do so.

Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency (P. 409). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
Automatic operation of the seat heater during Eco drive mode
If the driving mode select switch is switched to Eco drive mode in cold tem-
peratures, the seat heater will be automatically operated to assist heating per-
formance.
Sport mode automatic deactivation
Sport mode is automatically deactivated if the engine switch is turned off
after driving in sport mode.

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)

GS350/250_EE (OM30C36E)
The pre-crash safety system is operational when
The pre-crash safety system off button is not pressed and the following con-
ditions are met:
Pre-crash warning:
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or oncoming
vehicle is greater than about 15 km/h (10 mph).
Pre-crash seat belts (operating conditions A):
• Vehicle speed is greater than about 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-crash seat belts (operating conditions B):
• Vehicle speed is greater than about 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or oncoming
vehicle is greater than about 30 km/h (19 mph).
• The front occupants are wearing a seat belt.
Pre-crash brake assist:
• Vehicle speed is greater than about 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than about 30 km/h (19 mph).
• The brake pedal is depressed.
Pre-crash braking:
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than about 15 km/h (10 mph).
Suspension control:
• Vehicle speed is greater than about 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than about 30 km/h (19 mph).

Driving

Pre-crash alert braking:
• The system determines that the driver is not facing forward, or that the
driver’s eyes are closed.
• Vehicle speed is greater than about 40 km/h (25 mph).
• The speed at which your vehicle is approaching the vehicle running
ahead of you is greater than about 40 km/h (25 mph).
• The steering is not being turned.
Conditions that may trigger the system even if there is no danger of a collision
When there is an object by the roadside at the entrance to a curve
When passing an oncoming vehicle on a curve
When driving over a narrow iron bridge
When there is a metal object on the road surface
When driving on an uneven road surface
When passing an oncoming vehicle on a left-turn (left-hand drive vehicles)
or right-turn (right-hand drive vehicles)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
When climbing a steep hill causes an overhead billboard or other metallic
structure to appear directly in the vehicle’s line of travel
When the system is activated in the situations described above, there is also a
possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.
Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.
