cle with a 12-volt battery, you can jump start your Scion following
the steps below.

Positive (+) battery terminal on your vehicle
Positive (+) battery terminal on the second vehicle
Negative (-) battery terminal on the second vehicle
Connect the jumper cable to ground on your vehicle 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

■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.
