To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
On vehicles with the 3.8L V6 engine,
the coolant heater cord is located on the
passenger’s side of the vehicle, above the
headlamp assembly. On vehicles with the 4.6L
V8 engine, the cord is located on the driver’s
side of the vehicle on the right side of the
engine air cleaner. It is between the engine
cover and the engine air cleaner.
{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.3. Plug the cord into a normal, grounded
110-volt AC outlet.
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 Dimming Rearview Mirror
with Compass
Your vehicle may have an automatic dimming
rearview mirror with a compass. This feature
enables the mirror to sense nighttime glare from
vehicle headlamps from behind and automatically
dim to reduce the glare to a safe level. The
automatic dimming feature turns on each time the
vehicle is started.
O(On/Off):This is the on/off button.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on
automatically each time the ignition is started. To
operate the automatic dimming mirror, do the
following:
1. Make sure the indicator light, located to the left
of the on/off button, is on. If it’s not, press and
hold the on/off button until the light comes on,
indicating that the mirror is in automatic
dimming mode.
2. Turn off the automatic dimming mirror function
by pressing and holding the on/off button until
the indicator light turns off.
Compass Operation
Press the on/off button once to turn the compass
on or off.
When the ignition and the compass feature are
on, the compass will show two character boxes for
a few seconds. After a few seconds, the mirror
will display the current compass direction.
Compass Calibration
If after a few seconds the display does not show a
compass direction, (N for North for example), there
may be a strong magnetic eld interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, note pad holder, or
similar object. If the letter C or CAL appears in the
compass window, the compass may need to be
reset or calibrated.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
132

will adjust for the glare of headlamps behind you.

heated driver’s and passenger’s outside rearview
mirrors are warmed to help clear them of ice and
snow. See “Rear Window Defogger” underClimate
Control System on page 182orDual Automatic
