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 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
passenger’s side of the vehicle, above the headlamp
assembly.
3. Plug it 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.

Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off after
you remove the key from the ignition.
Delayed Exit Lighting
This feature will turn on the interior lamps for 25 seconds
after you remove the key from the ignition while the
doors are closed and it is night. This will give you time
to nd the door handle or lock switches as you exit
the vehicle.
This lighting will only be deactivated if the key is
reinserted into the ignition switch or the power door
locks are activated.
Parade Dimming
To activate the instrument panel backlighting during the
day, turn the exterior lamp switch to the parking lamp or
headlamp position. Dimming of the instrument panel
display is not possible during daylight hours. The
instrument panel display can only be adjusted when the
parking lamps or headlamps are on and it is dark outside.
Perimeter Lighting
When the unlock button on the remote keyless entry
transmitter (if equipped) is pressed, the DRL headlamps,
parking lamps and back-up lamps will turn on if it is
dark enough outside.
Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
If your vehicle is equipped with the Driver Information
Center (DIC), you must program this feature through the
DIC. SeeDIC Vehicle Personalization on page 3-64.
To turn the feature off do the following:
1. Keep all doors closed, the vehicle in PARK (P) and
the ignition on throughout this procedure.
2. Press and hold LOCK on the power door lock
switch throughout this procedure. All the doors
will lock.
3. Press the remote alarm button on the transmitter.
Perimeter lighting remains on at this time and the
horn will chirp twice.
4. Press the remote alarm button again. Perimeter
lighting is disabled and the horn will chirp once.
5. Release the door lock switch. The perimeter lighting
feature is now off.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
{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 can not 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.

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 5 years or 150,000 miles
(240 000 km), whichever occurs rst, if you add
only 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 5-29.
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 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.
What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOL®coolant which won’t damage
aluminum parts. If you use this coolant mixture,
you don’t need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will.
CAUTION: (Continued)
5-26

CAUTION: (Continued)
Your vehicle’s coolant warning system is set for
the proper coolant mixture. With plain water or
the wrong mixture, your engine could get too
hot but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use the proper coolant, you do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The engine coolant
recovery tank is located in
the engine compartment
on the passenger’s side of
the vehicle, near the
windshield. SeeEngine
Compartment Overview on
page 5-14for more
information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
FULL COLD mark or a little higher. When your engine is
warm, the level should be up to the FULL HOT mark
or a little higher.
5-27

If No Steam Is Coming From Your
Engine
If you get an engine overheat warning but see or hear
no steam, the problem may not be too serious.
Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there’s still no sign of steam, you can idle the engine
for three minutes while you’re parked. If you still
have the warning,turn off the engine and get everyone
out of the vehicleuntil it cools down.
You may decide not to lift the hood but to get service
help right away.

SeeEngine Compartment
Overview on page 5-14for
more information on
location.
The coolant level should be at or above the FULL COLD
mark when the engine is cold. The coolant level
should be at the FULL HOT mark under normal
operating conditions. If it is not, you may have a leak at
the pressure cap or in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If
you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running. If they are not, your vehicle needs service.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
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 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.
