PRIUS_OM_OM47A17U_DVD_(U)
Hybrid battery (traction battery) air vent
There is an air intake vent on the
right side of the rear seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vent becomes blocked, the
hybrid battery (traction battery)
may overheat, leading to a
reduction in hybrid battery (trac-
tion battery) output.
Emergency shut off system When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize t he risk of electrocution and fuel
leakage. If the emergency shut off sy stem activates, your vehicle will
not restart. To restart the hybrid system, contact your Toyota dealer.
Hybrid warning message
A message is automatically displa yed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( P. 517)

40 1-1. Hybrid system
PRIUS_OM_OM47A17U_DVD_(U)
■If a warning light comes on, a warn ing 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 your Toyota dealer.
■ Running 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. 508) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 1.9 gal. [7.1 L,
1.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
■ Electromagnetic waves
●High 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.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

have been locked/unlocked. (Locked: Once; Unlocked: Twice)
■ When the door cannot be locked by the lock sensor on the upper part
of the door handle
■ Alarms and warning lights
A combination of exterior and interior alarms as well as warning lights are
used to prevent theft of the vehicle and accidents resulting from erroneous
operation. Take appropriate measures in response to any warning message
shown on the multi-information display. ( P. 531)
The following table describes circumstances and correction procedures
when only alarms are sounded.
