1-7. Theft deterrent system
PRIUS +_OM_OM47821E_(EE)
Alarm
: If equipped
The system sounds the alarm and flashes lights when forced entry is
detected.
Triggering of the alarm
The alarm is triggered in the following situations when the alarm
is set.
A locked door or back door is unlocked or opened in any way
other than using the entry function or wireless remote control.
The hood is opened.
If equipped, the intrusion sensor detects something moving
inside the vehicle. (An intruder gets in the vehicle.)
If equipped, the quarter windows or back door window are
tapped or broken.
Setting the alarm system
Close the doors and hood,
and lock all doors using the
entry function or wireless
remote control. The system
will be set automatically after
30 seconds.
The indicator light changes
from being on to flashing when
the system is set.

The vehicle is inside an automatic or high-pressure car wash.
The vehicle experiences impacts, such as hail, lightning strikes, and
other kinds of repeated impacts or vibrations.
Unstable items, such as dangling
accessories or clothes hanging on the
coat hooks, are in the vehicle.
The vehicle is parked in a place where
extreme vibrations or noises occur,
such as in a parking garage.
Ice or snow is removed from the vehi-
cle, causing the vehicle to receive
repeated impacts or vibrations.

Before driving
PRIUS +_OM_OM47821E_(EE)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 occu-
pants.
If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.
The windshield may crack.
SRS airbag deployment conditions (SRS front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wall that
does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle and sign pole, which can move
or deform on impact, or if the vehicle is involved in an underride collision
(e.g. a collision in which the front of the vehicle “underrides”, or goes
under, the bed of a truck, etc.).
Depending on the type of collision, it is possible that only the seat belt
pretensioners will activate.

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 pro-
vides 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 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 air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintaining
control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunc-
tion in the system. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Neither “ON” nor “OFF” comes on.
The indicator light does not change when the airbag manual on-off switch
is switched to “ON” or “OFF”.
CAUTION
When installing a child restraint system
For safety reasons, always install the child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as
long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
When a child restraint system is not installed on the front passenger
seat
Ensure that the airbag manual on-off system is set to “ON”.
If it is left off, the airbag may not deploy in the event of an accident, which
may result in serious injury or even death.

PRIUS +_OM_OM47821E_(EE)
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 542)
For efficient use
Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift position in the N position for an extended period of time
may discharge the hybrid battery (traction battery). The vehicle cannot
run if the hybrid battery (traction battery) is discharged.
CAUTION
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid sys-
tem operating. This prevents the vehicle from creeping.
