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

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 engine to return to nor-
mal operation; or have it repaired if
necessary.
