Engine Fan Noise
This vehicle has
a
clutched engine cooling fan. When the clutch is engaged,
the fan spins faster to provide more air to cool the engine. In most every day

and/or high outside temperatures, the fan speed increases when the clutch
engages.

the
vehicle
toward that side. Take your foot off the accelerator pedal and grip the
steering wheel firmly. Steer
to
maintain lane position, then gently brake to a
stop well out of the traffic lane.
