with a 12-volt battery, you can jump start your vehicle by following the
steps below.
Open the hood. ( P. 205)
Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other e nd of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the battery
and any moving parts, as shown in the illustration.

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the batter y of your vehicle.
Maintain the engine speed of the second vehicle and turn the
engine switch to the “ON” position, then start the vehicle's engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the ve hicle inspected at your Scion
dealer as soon as possible.
n Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
n To prevent battery discharge
lTurn off the headlights and the air conditioning system while the engine is
off.
l Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
n 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.)

WARNING
nAvoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
lMake sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
l Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
l Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
l Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
n Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:
lWhen working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
l Do not lean over the battery.
l In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
l Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
l Do not allow children near the battery.
