this range if at room temperature
(10°C-35°C [50°F-95°F]) (see
figure to the right).

for an extended period at high
speeds, in city traffic during hot
weather or pulling a trailer, the
vehicle should be turned off for
about 30 minutes to allow the fluid
to cool before checking.

surface and engage the parking
brake.

(Park) and leave the engine
running.
