If the engine will not star t
If the engine will not start even though correct starting procedures
are being followed ( P. 117), consider each of the following points:
■The engine will not start even though the starter motor
operates normally.
One of the following may be the cause of the problem:
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
● The engine may be flooded.
Try to restart the engine again following correct starting proce-
dures. ( P. 1 1 7 )
● Vehicles with engine immobilizer system: There may be a
malfunction in the engine immobilizer system. (P. 6 4 )
■ The starter motor turns over slowly, the interior lights and
headlights are dim, or the horn does not sound or sounds at
a low volume.
One of the following may be the cause of the problem:
●The battery may be discharged. ( P. 319)
● The battery terminal connec tions may be loose or corroded.
■ The starter motor does not turn over, the interior lights and
headlights do not turn on, or the horn does not sound.

If the shift lever cannot be shifted from P (automatic transmission)
If the shift lever cannot be shifted with your foot on the brake pedal,
there may be a problem with the shift lock system (a system to pre-
vent accidental operation of the shift lever). Have the vehicle
inspected by your Scion dealer immediately.
The following steps may be used as an emergency measure to
ensure that the shift lever can be shifted:
Set the parking brake.
Turn the engine switch to the “ACC” position.
Depress the brake pedal.
Pry the cover up with a flat-
head screwdriver or equiva-
lent tool.
Press the shift lock override
button.
The shift lever can be shifted
while the button is pressed.

If the vehicle batter y is discharged
The following procedures may be used to start the engine if the vehi-
cle’s battery is discharged.
You can also call your Scion dealer or a qualified repair shop.
If you have a set of jumper (or booster) cables and a second vehi-
cle with a 12-volt battery, you can jump start your vehicle by follow-
ing the steps below.
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.
■ 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.)
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.
Once the engine starts, have the vehicle inspected at your Scion
dealer as soon as possible.STEP 3

If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing 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 (radia-
tor) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your Scion
dealer.
The following may indicate that your vehicle is overheating.
●The high engine coolant te mperature warning light ( P. 290)
comes on or flashes, or a loss of engine power is experienced.
(For example, the vehicl e speed does not increase.)
● Steam is coming from under the hood.

The coolant level is satisfactory if
it is between the “FULL” and
“LOW” 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 air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from t he 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 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 engine 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 any coolant additive.

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. 151)STEP 1
