“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.414)

The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir when the hybrid sys-
tem 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.414)
■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” 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: - 35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, engine/power control unit coolant reser-
voir caps, drain cock and water pump. If you cannot find a leak, have any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer, test the cap and check for leaks in the cooling system.
WARNING
■When the hybrid system is hot
Do not remove the engine/power con-
trol unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.

7-2. Steps to take in an emergency
When trouble arises
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 traction.
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 accelerator pedal.
■When it is difficult to free the vehi-
cle
Press the switch to turn off TRC.
A message will be shown on the multi-
information display.
WARNING
●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.
●After the hybrid system has been turned off, check that the “READY”
indicator is off. When the hybrid system is operating, the gasoline engine may automatically start, or
the cooling fan may suddenly oper- ate even if the gasoline engine stops. Do not touch or approach
rotating parts such as the fan, which may lead to fingers or cloth-ing (especially a tie, a scarf or a
muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the hybrid system and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine/power con-trol 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 dam-
age to the hybrid 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 additive.
If the vehicle becomes
stuck
Carry out the following proce-
dures if the tires spin or the
vehicle becomes stuck in mud,
dirt or snow:
