2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as you
hold the key in START for up to a maximum of
15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool
down. When the engine starts, let go of the key
and accelerator. If the vehicle starts briey but
then stops again, do the same thing. This
clears the extra gasoline from the engine. Do
not race the engine immediately after starting
it. Operate the engine and transaxle gently
until the oil warms up and lubricates all
moving parts.Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (−18°C) or colder, the engine coolant heater
can help. You’ll 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.
117

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.

Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The knob for this control is located next to the
exterior lamps control.
Push the knob in and release when it pops out.
Turn the knob clockwise to increase the brightness
of the instrument panel lights and counter clockwise
to decrease the brightness. Turning the knob
completely clockwise to the detent will turn on the
courtesy lamps.
Courtesy Lamps
When any door is opened, several lamps turn on
making it easier for you to enter and exit the
vehicle. Turn the instrument panel brightness
control completely clockwise to manually turn
on these lamps.
Entry Lighting
If it is dark enough outside when you press the
unlock button on the remote keyless entry
transmitter, the interior courtesy lamps will turn on
and stay on for about 40 seconds. The lamps can
be turned off immediately by pressing the lock
button on the remote keyless entry transmitter,
turning the ignition key to RUN or activating the
power door locks.
Delayed Entry Lighting
The interior lamps will turn on if you open the door
when it is dark enough outside. When you close the
door with the ignition off, the interior lamps will stay
on for up to 25 seconds or until the ignition is turned
to an on position. When the lamps turn off as a
result of the 25 second timer or the ignition switch
being turned on, the lighting will deactivate by way
of the theater dimming effect. Locking the doors will
override the delayed entry lighting feature and the
lamps will turn off right away.
174

Theater Dimming
This feature allows for a three to ve-second fade
out of the courtesy lamps instead of immediate
turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove
the key from the ignition, the interior lamps will turn
on and stay on for about 25 seconds. This will
give you time to nd the door pull handle or lock
switches. Once the key is inserted into the ignition,
the exit lighting will be cancelled and the lighting
will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button
on the remote keyless entry transmitter is pressed,
the DRL, parking lamps and back-up lamps will
come on.
This feature can be programmed on for various
amounts of time in seconds for each transmitter.
SeeDIC Vehicle Customization on page 231
for information on programming.
Front Reading Lamps
The front reading lamps, located on the headliner,
are turned on or off by pressing one of the buttons
located near each lamp.

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.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck,
you will need to spin the wheels, but you do not
want to spin your wheels too fast. The method
known as rocking can help you get out when you
are stuck, but you must use caution.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. And, the transaxle or
other parts of the vehicle can overheat.
That could cause an engine compartment
re or other damage. When you are stuck,
spin the wheels as little as possible. Do not
spin the wheels above 35 mph (55 km/h) as
shown on the speedometer.
Notice:Spinning the wheels can destroy parts
of your vehicle as well as the tires. If you spin
the wheels too fast while shifting the transaxle
back and forth, you can destroy the transaxle.
SeeRocking Your Vehicle to Get It Out on
page 307.
For information about using tire chains on your
vehicle, seeTire Chains on page 406.

Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 351.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
