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 quickl y fills the
airbags with non-toxic gas to help restrain the motion of the o ccu-
pants.

WARNING
QSRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
O 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 se at belts.
O 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 - 7 5 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 measu red 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 sev-
eral ways:
• Move your seat to the rear as far as you can while still reach ing the ped-
als comfortably.
• Slightly recline the back of the seat. Although vehicle design s vary,
many drivers can achieve the 250 mm (10 in.) distance, even wit h the
driver seat all the way forward, simply by reclining the back o f the seat
somewhat. If reclining the back of your seat makes it hard to s ee 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 p oints the air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still m aintain-
ing control of the foot pedals, steering wheel, and your view o f the instru-
ment panel controls.
O The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passe nger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passen ger sits
upright.
O Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child res traint sys-
tem. Toyota strongly recommends that all infants and children b e placed in
the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 54)

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is co lorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
Q Important points while driving
O Keep the back door closed.
O If you smell exhaust gases in the vehicle even when the back door is
closed, open the side windows and have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer as soon as possible.
Q When parking
O If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.
O Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an o pen space
and ensure that exhaust fumes do not enter the vehicle interior .
O Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle w hile the
hybrid system is operating, exhaust gases may collect and enter the vehi-
cle.
Q Exhaust pipe
The exhaust system needs to be checked periodically. If there i s a hole or
crack caused by corrosion, damage to a joint or abnormal exhaus t noise, be
sure to have the vehicle inspected and repaired by any authoriz ed Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.

521-2. Child safety
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
Insert the mechanical key into the
cylinder and turn to the “OFF”
position.
The “OFF” indicator light turns on
(only when the power switch is in
ON mode).
Q “PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that the re is a malfunction
in the system. Have the vehicle inspected by any authorized Toy ota retailer or
Toyota authorized repairer, or any reliable repairer.
O The “OFF” indicator does not illuminate when the airbag manual on-off
switch is set to “OFF”.
O The indicator light does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.
Deactivating the airbags for the front passenger
WARNING
Q When installing a child restraint system
For safety reasons, always install the child restraint system i n 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 impac t of the airbag
deployment (inflation) may cause serious injury or even death.
Q 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.

1002-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
QIf a warning light comes on, a warning message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized To y o t a
retailer or Toyota authorized repairer, or any reliable repairer.
QRunning out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light (P. 660) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
7.5 L [2.0 gal., 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
QElectromagnetic waves
OHigh voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
OYour vehicle may cause sound interference in some third party-produced
radio parts.
QEffect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are
placed inside the luggage compartment or installed nearby, the generated
magnetic forces may negatively affect the hybrid system.
QHybrid battery (traction battery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The hybrid battery (traction battery) capacity (the ability to hold a charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how
the vehicle is driven and how the hybrid battery (traction battery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion. Also, even though the distance that can be driven in EV mode decreases
when the hybrid battery (traction battery) capacity reduces, vehicle perfor-
mance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, follow the directions
listed on P. 152, “Capacity reduction of the hybrid battery (traction battery)”.
QStarting the hybrid system in an extremely cold environment
When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -30C [-22F]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to the
outside temperature increase etc.

QWhen charging
Observe the following precautions.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.
O Connect to a power source suitable for charging. (P. 139)
O Before charging, check that the charging inlet does not have deformations,
damage, corrosion, dust or other foreign materials such as snow or ice
adhering to it. If anything is adhering to the inlet, be sure t o completely
remove the material before connecting the charging connector.
O Mode 3 charging cable: Before inserting the charging plug into the char-
ger, make sure there is no dirt or dust on the terminal areas. If there is dirt
or dust on these areas, remove it completely before inserting t he charging
plug.
