Connect the jumper cables accord
ing 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 termin al 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 battery of your vehicle.

■Starting the engine when the battery is discharged
Vehicles with an automatic transmission, the engine cannot be started by
push-starting.
■ To prevent battery discharge
● Turn off the headlights and the air conditioning 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.
Maintain the engine speed of the second vehicle and start
the engine of your vehicle by turning the engine switch to
the “ON” position.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse or der from which they were con-
nected.
Reinstall the service cover as
shown in the illustration.
Reinstall the engine cover: Conduct the removal procedure
in reverse. After installing, ch eck that the clips are inserted
securely.
Once the engine starts, have the vehicle inspected at your Scion
dealer as soon as possible.STEP 5

■
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 each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
■ 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:
● When 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.
● Do not lean over the battery.
● 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.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.

CAUTION
■To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
may overheat and become a fire hazard.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans or belt.
■ To prevent damage to the engine cover
● When removing the cover, make sure that you pull the cover towards you
after lifting the front edge to remove the fixed pins.
● When installing the cover, do not force the cover or subject it to strong
shocks.

If your vehicle overheats
The following may indicate that your vehicle is overheating.
●The high engine coolant te mperature warning light (P. 305)
comes on or a loss of engine power is experienced. (For exam-
ple, the vehicle speed does not increase.)
● Steam comes out from under the hood.
Follow the correction pro cedure as described below.
Stop the vehicle in a safe place and turn off the air condi-
tioning system, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam: Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radi-
ator) for any leaks.

Cooling fan
If a large amount of coolant
leaks, immediately contact
your Scion dealer.

The coolant level is satisfac-
tory if it is between the “F” and
“L” lines on the reservoir.Reservoir
Full
Low
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the ai r conditioning system on to
check that the radiator cooling fan operates and to check
for coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact your Scion
dealer.
If the fan is operating: Have the vehicle inspected at the nearest Scion dealer.

CAUTION
■
To prevent an accident or injury when inspecting under the hood of
your vehicle
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use commercially available coolant additives.

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding area is clear to avoid striking other vehicles, objects or people. The
vehicle may also lunge forward or lunge back suddenly as it becomes free.
Use extreme caution.
■ When shifting the shift lever
For vehicles with an automatic transmission, be careful not to shift the shift
lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident resulting in death or serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Stop the engine. Set the parki ng brake and shift the shift
lever to P (automatic transmission) or N (manual transmis-
sion).
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the engine.
Shift the shift lever to the D or R position (automatic trans-
mission) or 1 or R position (manual transmission) and care-
fully apply the accelerator to free the vehicle.
Turn off TRAC and VSC if these functions are hampering
your attempts to free the vehicle. ( P. 165)STEP 1
