pets left inside the vehicle may
suffer heatstroke dehydration or
hypothermia, or could result in
death or serious injury.

environment, signals from the
wireless switch may transmit
further than expected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when necessary.
●Do not operate “A/C” if the hood
is open. The air conditioning
may operate unintentionally and
objects may be drawn into the
electrical cooling fan.
