Engine Heater
The engine heater can provide
easier starting and better fuel
economy during engine warm-up
in cold weather conditions at or
below
− 4°F ( − 20°C). Vehicles with
an engine heater should be plugged
in at least four hours before starting.
To Use the Engine Heater
1. Turn off the engine.
2. The engine heater connector is
located in the passenger side
lower front grille. Open the cover
and insert the 110-volt AC
adapter delivered in the vehicles
glove box.
3. Plug the other end of the adapter
into a grounded 110-volt AC
outlet.
{ CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug both ends of
the adapter and store the adapter
to prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
