This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
climbing steep grades in high tempera-
tures with heavy loads, such as when tow-
ing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce thechance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be reduced.
WARNING
When the high fluid temperature pro-
tection mode operation occurs, vehicle
speed may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially
careful when driving. If necessary, pull
to the side of the road at a safe place

cally to reduce the chance of engine dam-
age. Vehicle speed can be controlled with
the accelerator pedal, but the engine and
vehicle speed may be reduced.
