Service CVT (AT) Power reduced (if so
equipped)
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 the
chance 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 and allow the
transmission to return to normal op-
eration; or have it repaired if necessary.
