2009 TOYOTA PRIUS charging

24 1-1. Hybrid system
PRIUS_U_(OM47614U)
■Charging the battery
● As the gasoline engine charges the hybrid battery (traction battery), the
battery does not need to be charged from an outside source. However, if
the vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every
several months for at least 30 minutes or 10 miles (16 km). If the hybrid
battery becomes fully discharged and you are unable to jump-start the
vehicle with the 12 volt battery, contact your Toyota dealer.
● If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
lever in “D” to avoid discharging the battery.
■ After the 12 volt battery has di scharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact your Toyota
dealer.

■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle and electronic key batteries from discharging.
● When the entry function has not been used for 2 weeks or more
● When the electronic key has been left within approximately 3 ft. (1 m) of
the vehicle for 10 minutes or more
The system will resume operation when...
● The vehicle is locked using the door handle lock switch
● The vehicle is locked/unlocked using the wireless remote control function
(P. 49) or the mechanical key ( P. 448)
■ Electronic key battery depletion
● The standard battery life is 1 to 3 years. (The battery becomes depleted
even if the electronic key is not used.) If the smart key system or the
wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when
necessary. (  P. 392)
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliance that produce a magnetic field.
•TVs
• Personal computers
• Recharging cellular phones or cordless phones
• Table lamps
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.

Before driving
PRIUS_U_(OM47614U)
CAUTION
■
When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so, may result in death or serious injury.
● Touch the vehicle or some other metal surface to discharge any static
electricity.
Sparks resulting from discharging static electricity may cause the fuel
vapors to ignite.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
bodies to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Failure to do so may cause a fire or other incident which may result
in death or serious injury.
NOTICE
■Refueling
Do not spill fuel during refueling.
Failing to do so may damage the vehicle, such as causing the exhaust sys-
tems to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

■Before recharging
When recharging, the 12 volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, before recharging:
● If recharging with the 12 volt battery installed on the vehicle, be sure to
disconnect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12 volt battery.
■ After recharging/reconnecting the 12 volt battery
In some cases, the hybrid system may not start. Follow one or both of the
following procedures:
● After opening and closing the driver’s door, wait 10 seconds then attempt
to start the engine. (If the system does not start first time, repeat the pro-
cedure.)
● With the shift lever in “P” and the “POWER” switch in the OFF mode,
open and close any door, then attempt to start the hybrid system.
If the system will not start even after multiple attempts at both methods, con-
tact your Toyota dealer.

Never recharge the 12 volt battery while the hybrid system is operating.
Also, be sure all accessories are turned off.
CAUTION
■ When refilling the washer fluid
Do not refill the washer fluid when the hybrid system is hot or operating, as
the washer fluid contains alcohol and may catch fire if spilled on the hybrid
system etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
