Checking the coolant level

Gasoline engine coolant reservoir
perfor-
Inverter coolant reservoir
'07 HIGHLANDER HV_U (L/O 0608)
Look at the see−through coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the "FULL" and "LOW" lines
on the reservoir. If the level is low, add
coolant. (For coolant types, see "Cool-
ant type selection" described below.)
The coolant level in the reservoir will vary
with hybrid system temperature. However,
if the level is on or below the "LOW" line,
add coolant. Bring the level up to the
"FULL" line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
To prevent burning yourself, do not
remove the radiator cap when the
coolant may be hot.
