■When inspecting under the
hood of your vehicle
Observe the following precau-
tions. 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 sub-
sided. The engine compart-

4928-2. Steps to take in an emergency
COROLLA HV_U
1Stop the hybrid system. Set
the parking brake and shift
the shift lever to P.
2 Remove the mud, snow or
sand from around the front
wheels.
3 Place wood, stones or some
other material under the front
wheels to help provide trac-
tion.
4 Restart the hybrid system.
5 Shift the shift lever to D or R
and release the parking
brake. Then, while exercising
caution, depress the acceler-
ator pedal.
■When it is difficult to free the
vehicle
Press the switch to turn off
TRAC.
WA R N I N G
●After the hybrid system has
been turned off, check that the
“READY” indicator is off. When
the hybrid system is operating,
the gasoline en gine may auto-
matically start, o r the cooling
fans may suddenly operate
even if the gasoline engine
stops. Do not touch or approach
rotating parts such as the fan,
which may lead to fingers or
clothing (especially a tie, a scarf
or a muffler) getting caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir caps while the hybrid sys-
tem and radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine/power
control unit coolant
Add coolant slowly after the
hybrid system has cooled down
sufficiently. Adding cool coolant to
a hot hybrid system too quickly
can cause damage to the hybrid
system.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.
If the vehicle becomes
stuck
Carry out the following pro-
cedures if the tires spin or
the vehicle becomes stuck
in mud, dirt or snow:
