Automatic Transmission
Fluid When to Check and Change
Automatic Transmission Fluid It is usually not necessary to
check the transmission fluid level.
The only reason for fluid loss is a
transmission leak or overheating
the transmission. If a small leak is
suspected, then use the following checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer and have it repaired before
driving the vehicle further.
Notice: Use of the incorrect
automatic transmission fluid
may damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11 ‑ 2 .
Change the fluid and filter at the
scheduled maintenance intervals.
See “ Scheduled Maintenance ” in
the owner manual. Be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11 ‑ 2 .

If the coolant inside the DMCM
coolant surge tank is boiling, do not
do anything else until it cools down.
The coolant level should be at
or above the FULL COLD mark
with the vehicle parked on a level surface. If it is not, there might be
a leak at the DMCM cooler core,
DMCM pressure cap, DMCM cooler
hoses, DMCM cooling pump or
somewhere else in the DMCM
cooling system.
Notice: Running the engine when
there is a leak in the hybrid
cooling system can cause the
hybrid cooling system to lose
all coolant and can damage the
system. Get any leak fixed before
you drive the vehicle or run the
engine.
