Repair and replacement

It is recommended that genuine Scion parts be used for repairs to ensure per-
formance of each system. If non-Scion parts are used in replacement or if a
repair shop other than a Scion dealer performs repairs, confirm the warranty
coverage.

■

Allow inspection and repairs to be performed by a Scion dealer

●

Scion technicians are well-trained specialists and are kept up to date with
the latest service information. They are well informed about the operations
of all systems on your vehicle.

●

Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, your Scion dealer will promptly take
care of it.

CAUTION

■

If your vehicle is not properly maintained

Improper maintenance could result in serious damage to the vehicle and
possible death or serious injury.

■

Handling of the 12-volt battery

●

Fluids contained in vehicles as well as waste produced by component
wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Avoid exposure and
wash any affected area immediately.

●

12-volt battery posts, terminals and related accessories contain lead and
lead compounds which are known to cause brain damage. Wash your
hands after handling. (

CAUTION

The motor compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:

■

When working on the motor compartment

●

Make sure that the indicator on the power switch and the “READY” indica-
tor are both off.

●

Keep hands, clothing and tools away from the moving fan.

●

Be careful not to touch the motor, power control unit, radiator, etc. right
after driving as they may be hot. Coolant and other fluids may also be hot.

●

Do not leave anything that may burn easily, such as paper and rags, in the
motor compartment.

●

Do not smoke, cause sparks or expose an open flame to the 12-volt bat-
tery. 12-volt battery fumes are flammable.

●

Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.

●

Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.

■

When working near the electric cooling fan or radiator grille

Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fan may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (

■

Safety glasses

Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

Inspecting the charging cable

Check that the electrical leakage detection function operates properly
by following the procedure below.
In the unlikely event that the electrical leakage detection function does
not operate properly, contact your Scion dealer as soon as possible.

Insert the charging cable into the outlet of the external power
source.

Press the test button on the
CCID (Charging Circuit Inter-
rupting Device).

If the error warning indicator illumi-
nates when the test button is
pressed, the function is operating
correctly.

Press the reset button on the CCID (Charging Circuit Interrupting
Device).

Check that the error warning indicator turns off. Charging cannot be car-
ried out while the error warning indicator is illuminated.
Charging can be continued by following the normal procedure. If not charg-
ing, put away the charging cable.

For safety, inspect the charging cable on a routine basis (at least
once a month).

CAUTION

■

Routine inspection

Check the following points regularly.
If use is continued without inspection, fire or electric shock may occur, pos-
sibly resulting in death or serious injury.

●

The charging cable, plug, charging connector, CCID (Charging Circuit
Interrupting Device) etc. have not been damaged

●

The outlet has not been damaged

●

The plug does not get extremely hot during use

●

The tip of the plug has not been deformed

●

The plug is not dirtied by dust etc.

Inspect the plug after removing it from the outlet.

■

Maintaining the charging cable

When the cable is dirty, first remove the dirt with a hard, wringed cloth, and
then wipe the cable with a dry cloth. Do not wash with water, as doing so
could cause a fire or electrical shock when charging, which could lead to
death or serious injury.

■

When not using the charging cable for a long time

Remove the plug from the outlet. Dust could accumulate on the plug or in
the outlet, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.

264

Hood

Pull the hood lock release lever.

The hood will pop up slightly.

Pull up the auxiliary catch lever
and lift the hood.

Hold the hood open by inserting
the supporting rod into the slot.

Release the lock from the inside of the vehicle to open the hood.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

265

Mai

CAUTION

■

Pre-driving check

Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.

■

When opening the hood

Make sure to use the support rod to support the hood when opening it,
ensuring that the rod is fixed correctly. The hood may stay open without
support on slope, however, it is dangerous because the hood may suddenly
close.

NOTICE

■

When closing the hood

Be sure to return the support rod to its clip before closing the hood. Closing
the hood with the support rod up could cause the hood to bend.

CAUTION

■

When raising your vehicle

Make sure to observe the following precautions to reduce the possibility of
death or serious injury:

●

When using a floor jack, follow the instructions of the manual provided with
the jack.

●

Do not use the tire jack, which can be purchased at Scion dealer, for any
purposes other than replacing tires or installing and removing tire chains.
Otherwise, the vehicle may suddenly fall off.

●

Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.

●

Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.

●

Do not start the EV system while the vehicle is supported by the floor jack.

●

Stop the vehicle on level, firm ground, firmly set the parking brake and shift
the shift lever to P.

●

Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.

●

Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

268

CAUTION

●

Do not jack the vehicle at sections such as the rear suspension, traction
battery under cover and traction battery. The vehicle may be damaged.

●

Do not raise the vehicle while someone is in the vehicle.

●

When raising the vehicle, do not place any object on top of or underneath
the floor jack.
