58 1-5. Refueling
CAUTION
■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 of 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 Scion fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.
■ If you spill fluid
Be sure to wash it off with water to prevent damage to parts or paint.
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.

218 4-3. Do-it-yourself maintenance
Washer fluidIf any washer does not work or the low washer fluid warning light
comes on, the washer tank may be empty. Open the lid.
Add washer fluid.
NOTICE
■When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all
accessories are turned off.
CAUTION
■When refilling the washer fluid
Do not refill the washer fluid when the engine is hot or running, as the
washer fluid contains alcohol and may catch fire if spilled on the engine, etc.

274 5-2. Steps to take in an emergency
Stop the vehicle immediately.The following warnings indicate the possibility of damage to the vehi-
cle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your Scion dealer.
Warning lightWarning light/Details
Charging system warning light Indicates a malfunction in the vehicle’s charging sys-
tem.
Low engine oil pressure warning light Indicates that the engine oil pressure is too low.
(Flashes or comes on) High engine coolant temperature warning light
Indicates the engine is almost overheating.
(P. 308)

306 5-2. Steps to take in an emergency
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine is turned
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
●Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
● Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your Scion
dealer as soon as possible.
