The control panel is located in the center console.
Move the switch to
either
LO or HI to
turn on the heating
element in
the seat.
This feature is designed primarily for use on damp and chilly days. The
LO setting warms the seatback and cushion until the seat approximates
body temperature. On colder days, the
HI setting heats the seats to
an even higher temperature. To prevent uncomfortable overheating of
the seats, the heating elements are thermostatically regulated to
automatically maintain the temperature at the selected setting.
A telltale
light in the control switch reminds
you that the heating system is in use.
To preserve the battery, the heated seats can only be used when the
ignition is turned on, and are deactivated when the ignition
is turned off.

Reduce speed and shift to a lower gear before you start down a long or
steep downgrade.
If you don’t shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around 45 mph
(70 km/h) or less to reduce the possibility of engine and transaxle overheating.
If your trailer weighs more than 1,000 pounds (450 Kg) and you have an
automatic transaxle with Overdrive, you may want to drive in

of Overdrive

Engine damage from running your engine without coolant isn’t
covered
by your warranty.
If there seems to be no leak, check to see if the electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it.
(See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator fiose, heater hoses, radiator, -
water pump or somewhere else in the cooling system. -
