The switch used to adjust the pedals is located on
the center console below the climate control
system.
Press the right and left arrows to move the pedals
either closer or further from your body.
Your vehicle has a memory function which allows
seat settings to be saved and recalled. See
Memory Seat, Mirrors, and Pedals on page 13for
more information.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
143
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment, near
the power steering uid reservoir.
3. Plug the cord into a normal, 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 re. 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
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.Automatic Transmission Operation
Your vehicle has a Hydra-Matic®6L80 automatic
transmission, and has an electronic shift
position indicator within the instrument panel
cluster. The electronic shift position indicator
displays when the shift lever is moved out of
PARK (P). SeeFuses and Circuit Breakers
on page 507.

The recirculation mode cannot be selected while in
the defrost mode. The air conditioning compressor
will run automatically in this setting, unless the
outside temperature is close to freezing. Do not
drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):The rear window
defogger will turn off automatically after it has
been activated. The defogger can also be turned
off by pressing the button again or by turning
off the engine. Do not drive the vehicle until all the
windows are clear.
If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog or
frost from the surface of the mirror when the
rear window defog button is pressed.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the air outlets located in the center and on
the side of your instrument panel to direct
the air ow.
Operation Tips
Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as
leaves). The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
When you enter a vehicle in cold weather,
press the fan up button to the maximum
fan level before driving. This helps clear the
intake ducts of snow and moisture, and
reduces the chance of fogging the inside of
your window.
Keep the air path under the front seats
clear of objects. This helps air to circulate
throughout your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air de ectors, may
affect the performance of the heating and air
conditioning system. Check with your dealer
before adding equipment to the outside of your
vehicle.

{CAUTION:
Snow can trap exhaust gases under
your vehicle. This can cause deadly
CO (carbon monoxide) gas to get inside.
CO could overcome you and kill you.
You cannot see it or smell it, so you
might not know it is in your vehicle.
Clear away snow from around the base
of your vehicle, especially any that is
blocking your exhaust pipe. And check
around again from time to time to be
sure snow does not collect there.
Open a window just a little on the side
of the vehicle that is away from the wind.
This will help keep CO out.Run your engine only as long as you must.
This saves fuel. When you run the engine, make
it go a little faster than just idle. That is, push
the accelerator slightly. This uses less fuel for
the heat that you get and it keeps the battery
charged. You will need a well-charged battery
to restart the vehicle, and possibly for signaling
later on with your headlamps. Let the heater
run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start
the engine again and repeat this only when you
feel really uncomfortable from the cold. But do
it as little as possible. Preserve the fuel as long as
you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
