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.

2133-4. Adjusting the steering wheel and mirrors

Operation of each component
GS450h_300h_OM_OM30D53E_(EE)
Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
Linked mirror function when reversing
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 func-
tion, select neither “L” nor “R”.
If the mirror angle adjustment switch is operated while the linked mirror
function is in operation, the angle and position of the mirrors can be remem-
bered, and the mirrors will operate at the angle adjusted to the last time the
linked mirror function was operated.
However, because the mirrors move based on the angle they are in when the
linked mirror function is not operating, the mirror angle when the linked
mirror function is operating will also be changed if the mirrors are adjusted
while the function is not operating.
Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it
rains, the rain clearing (hydrophilic) effect of the mirrors causes the droplets
to be spread out into a film making the rear view clearer. In the following
cases, the rain clearing effect will be reduced temporarily, but will return
after 1 or 2 days’ exposure to direct sunlight.
After wiping dirt off the mirrors
When the mirrors fog up
After waxing your vehicle in an automatic car wash
After your vehicle has been parked for a long period in underground park-
ing lots etc. where there is no direct sunlight
When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers.
Turn on the rear window defogger to turn on the outside rear view mirror
defoggers. (P. 499)
Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automati-
cally by the driving position memory. (P. 199)

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When driving the vehicle
During normal driving, do not turn off the hybrid system. Turning the
hybrid system off while driving will not cause loss of steering or braking
control, however, power assist to the steering will be lost. This will make
it more difficult to steer smoothly, so you should pull over and stop the
vehicle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 8 2 1
Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 256)
Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid.
After driving through a puddle, depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.

Driving
GS450h_300h_OM_OM30D53E_(EE)
Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle run-
ning ahead of you should be equivalent to or greater than the
combined length of your vehicle and trailer. Avoid sudden brak-
ing that may cause skidding. Otherwise, the vehicle may spin out
of control. This is especially true when driving on wet or slippery
road surfaces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer col-
liding with your vehicle. Decelerate well in advance when
approaching turns and take them slowly and carefully to avoid
sudden braking.
Important points regarding turning
The wheels of the trailer will travel closer to the inside of the
curve than the wheels of the vehicle. To make allowance for this,
take the turns wider than you would normally do.
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and
strong crosswinds will affect handling. The vehicle may also be
rocked by passing buses or large trucks. Frequently check behind
when moving alongside such vehicles. As soon as such vehicle
movement occurs, immediately start to decelerate smoothly by
slowly applying the brakes. Always steer the vehicle straight
ahead while braking.
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.
