Driving
Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Inverter coolant
• Washer fluid
● Have a service technician inspec t the condition of the 12-volt bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following accordin g to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, ve hicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

Maintenance and care
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. ( P. 279)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

The coolant level is satisfactory if it is between the “F” (Full) and “L”
(Low) lines on the reservoir when the EV system is cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L”
line, add coolant up to the “F”
line. ( P. 390)
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -31 F [-35 C])
For more details about inverter coolant, contact your Scion dealer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, inverter coolant reservoir cap, drain cock
and water pump.
If you cannot find a leak, have your Scion dealer test the cap and check for
leaks in the cooling system.

CAUTION
■When the EV system is hot
Do not remove the inverter coolant reservoir cap. ( P. 391)
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

Maintenance and care
Check the radiator and condenser and clear away any foreign objects.
If either of the above parts is ex tremely dirty or you are not sure of
their condition, have yo ur vehicle inspected by your Scion dealer.
■Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
Radiator and condenser
CAUTION
■When the EV system is hot
Do not touch the radiator or condenser as they may be hot and cause seri\
-
ous injuries, such as burns.

3918-2. Steps to take in an emergency
8
When trouble arises
Add inverter coolant if nec-
essary. (P. 398)
Water can be used in an emer-
gency if inverter coolant is
unavailable.
Have the vehicle inspected at the nearest Scion dealer as soon as
possible.
■Overheating
If you observe the following, your vehicle may be overheating:
●“EV SYSTEM OVERHEAT” is shown on the multi-information display.
● EV system output decreases.
● Steam comes out from under the hood.
5
CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The motor compartment will be very hot.
● Keep hands and clothing away from the fan, etc. while the EV system is
operating.
● Even if EV system has stopped, the cooling fan may begin to move sud-
denly. Do not touch or approach the rotating parts of the fan. Doing so may
lead to fingers, clothes or tools getting caught, resulting in injury.
●Do not loosen the coolant reservoir cap
while the EV system and radiator are
hot.
High temperature steam or coolant
could spray out.

3928-2. Steps to take in an emergency
NOTICE
■When adding inverter coolant
Add coolant slowly after the EV system has cooled down sufficiently. Adding
cool coolant to a hot EV system too quickly can cause damage to the EV
system.
■ 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 additives other than the Scion genuine or similar
coolant additives.
