5-2. Steps to take in an emergency
If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing system.
Check to see if steam is coming out from under the hood.
If you see steam: Stop the EV system. Carefully lift the hood after the steam
subsides and then restart the EV system.
If you do not see steam: Leave the EV system operating and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating: Wait until “High Battery Temp” disappears and then stop the
EV system.
If the fans are not operating: Stop the EV system immediately and contact your Toyota
dealer.
After “High Battery Temp” disap-
pears, check the motor/traction
battery coolant level and inspect
the cooling system for leaks.
There are 2 powertrain coolant
reservoirs. Make sure to check
both of them.
If “High Battery Temp” is shown on the multi-information display, the
vehicle may be overheating.
If the message does not disappear after driving for a little while, fol-
low the correction procedu re as described below.

476 5-2. Steps to take in an emergency
If necessary, add motor/traction
battery coolant up to the “F” or
“FULL” line.
Add after confirming the type of
coolant. (P. 357)
Water can be used in an emer-
gency if motor/traction battery
coolant is unavailable.
Have the vehicle checked at nearest Toyota dealer as soon as possi-
ble.
STEP 5
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 motor compartment may be very hot, caus-
ing serious injury such as burns.
● Check that the indicator on the “POWER” switch and the “READY” indica-
tor are off.
● When the “READY” indicator is illuminated, the cooling fans may su\
ddenly
start to operate. Do not touch or approach the fans. Doing so may lead to
fingers, clothes or tools getting caught, resulting in an accidental injury.
● Do not loosen the coolant reservoir cap while the EV system and radiator
are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding motor/traction battery coolant
Wait until the EV system has cooled down before adding motor/traction bat-
tery coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot EV system
too quickly can cause damage to the EV system.
