■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 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 pedals com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, even with the driver seat all the wa y 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 recommend ed above, while still maintaining control
of the foot pedals, steering wheel, and yo ur view of the instrument panel controls.

1913-4. Adjusting the steering wheel and mirrors

Operation of each component
GS450h_300h_OM_OM30F00E_(EE)
■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 position.
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.

■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 changes.
■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. ( →P. 2 2 7 )
■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. 5 5 6 )

■Conditions in which the light distribution control of the headlights changes automati-
cally
●When all of the following conditions are met, the high beams will be turned on automat-
ically and the system will operate:
• The vehicle speed is approximately 60 km/h (37 mph) or more.*
*: The area in the direction that the vehicle is turning will be illuminated more brightly
than other areas while driving on a curve.
●When all of the following conditions are met, the variable high beams will turn on and
the distance that the low beams are projecte d will be adjusted automatically, depending
on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (37 mph) or more.
• The area ahead of the vehicle is dark.
• There are vehicles ahead with headlights or tail lights turned on.
●If any of the following conditions is met, the high beams or variable high beams will be
changed to the low beams automatically:
• The vehicle speed is below approximately 60 km/h (37 mph).
• The area ahead of the vehicle is not dark.
• There are many vehicles ahead.
• Vehicles ahead are moving quickly and the high beams may blind the drivers of the other vehicles.
■Camera sensor detection information
●The high beams may not be automatically ch anged to the variable high beams in the
following situations:
• When vehicles ahead suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road dividers or
roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
●The high beams may be changed to the variab le high beams if a vehicle ahead that is
using fog lights without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs may cause
the high beams to change to the variable high beams, cause the high beams not to
change to the variable high beams, or change the area that is not illuminated.
●The following factors may affect the amount of time taken to turn the high beam on or
off, or the speed by which the areas not illuminated change:
• The brightness of headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
●The light distribution control of th e headlights may change unexpectedly.
●Bicycles or similar objects may not be detected.

◆Pre-crash braking*3
When the system determines that the possibility of a frontal collision is high,
the system warns the driver. If the system determines that the possibility of a
collision is extremely high, the brakes are automatically applied to help avoid
the collision or reduce the collision speed.
*3: Depending on the region in which the vehicle was sold, the pre-crash braking function may not be available.
◆Suspension control (if equipped)
When the system determines that the possibility of a frontal collision is high,
the Adaptive Variable Suspension system ( →P. 345) will control the damping
force of the shock absorbers.
◆Steering control (if equipped)
When the system determines that the possibility of a frontal collision is high
and the driver is operating the steering wheel, the LDH system ( →P. 345) will
control the turning angle of the front an d rear wheels and effort necessary to
turn the steering wheel.

■Limitations of the pre-crash safety system
●The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under
any circumstances. This system will not pr event collisions or lessen collision damage
or injury in every situation. Do not overly rely on this system. Failure to do so may lead
to an accident, resulting in death or serious injury.
●Although this system is designed to help av oid a collision or help reduce the impact of
the collision, its effectiveness may change according to various conditions, therefore
the system may not always be able to achieve the same level of performance.
Read the following conditions carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may oper ate even if there is no possibility of a
collision: →P. 2 7 5
• Conditions under which the system may not operate properly: →P. 2 7 8
●Do not attempt to test the operation of the pre-crash safety system yourself, as the
system may not operate properly, possibly leading to an accident.

■Hands off steering wheel alert
When the system determines that the driver has removed their hands from the steering
wheel while the lane departure control function or lane centering function is operating, a
warning message is displayed on the multi-information display.
If the driver continues to keep their hands off of the steering wheel, the buzzer sounds, a
warning message is displayed and the function is temporarily canceled. This alert also
operates in the same way when the vehicle is driven with the steering wheel lightly
gripped. However, depending on the road conditions, etc., the function may not cancel.
■White (yellow) lines are only on one side of road
The LKA system will not operate for the side on which white (yellow) lines could not be
recognized.
■Conditions in which functi ons may not operate properly
