5. Safe operating level is within the
HOT cross hatch band on the
dipstick. If the fluid level is not
within the HOT band, and the
transmission temperature is
between 60°C and 75°C
(140°F and 167°F), add or
drain fluid as necessary to bring
the level into the HOT band.
If the fluid level is low, add only
enough fluid to bring the level
into the HOT band. It does not
take much fluid, generally less
than 0.5 Liter (1 Pint). Do not
overfill.
6. If the fluid level is in the
acceptable range, push the
dipstick back in all the way.

Consistency of Readings
Always check the fluid level at least
twice using the procedure described
previously. Consistency (repeatable
readings) is important to maintaining
proper fluid level. If readings are still
inconsistent, contact your dealer.

Cooling System
In addition to the regular cooling
system, the vehicle also has a
cooling system for the DMCM
system. This system is serviced
differently than the vehicle's main
cooling system. The DMCM cooling
system includes the DMCM coolant
surge tank, DMCM surge tank
pressure cap, DMCM cooling
pumps, hybrid cooling radiator
and the Drive Motor/Generator
Control Module (DMCM). The
DMCM cooling system uses a
50/50 pre-mixed DEX-COOL
coolant and deionized water
available at your dealer. See
