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.
Open the hood. ( P. 294)
Connect the jumper cables according to the following pro-
cedure:
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.

■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 audio system while the engine is 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.
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.
Vehicles with a smart key system only: Open and close any
of the doors of your vehicle with the “ENGINE START
STOP” switch off.
Maintain the engine speed of the second vehicle and start
the engine of your vehicle by turning the engine switch to
the “ON” position (vehicles without a smart key system) or
turning the “ENGINE START STOP” switch to IGNITION
ON mode (vehicles with a smart key system).
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

■
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.

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. 380)
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 fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are 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 fans may
not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Scion dealer.
If the fans are 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 injury such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fans 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
■When it is difficult to free the vehicle
Turn off TRAC and/or VSC if these functions are hampering your attempts to
free the vehicle. ( P. 216)
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
release the parking brake. Then, while exercising caution,
depress the accelerator pedal.STEP 1

If your vehicle has to be stopped in an emergency
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following pro-
cedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N After slowing down, stop the vehi cle in a safe place by the
road.
Stop the engine.
If the shift lever cannot be shifted to N Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
Vehicles without a smart key
system: Stop the engine by
turning the engine switch to
the “ACC” position.

CAUTION
■
If the engine has to be turned off while driving
● Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Vehicles without a smart key system: Never attempt to remove the key, as
doing so will lock the steering wheel.
Vehicles with a smart key sys-
tem: To stop the engine, press
and hold the “ENGINE START
STOP” switch for 2 consecu-
tive seconds or more, or press
it briefly 3 times or more in
succession.
Stop the vehicle in a safe place by the road.STEP 4
