Engine Coolant Heater
Your vehicle may be equipped with 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
For the 3.6L V6 engine, the cord is located in
the engine compartment on the passenger’s side of
the vehicle in front of the fuse block.
For the 4.6L V8 engine, the cord is located in the
engine compartment on the driver’s side of the
vehicle near the inner fender and above the strut.
For the 4.4L V8 engine, the cord is located in
the front of the engine compartment, on the
passenger’s side of the vehicle. The plug will be
inside the upper grille cutout.
3. You must remove the plastic cap to access
the plug.
4. 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 fire. 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.
5. 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.
2-27
Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane
change is complete. The lever returns to its original
position when it’s released.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other driver’s won’t see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. See
Fuses
and Circuit Breakers on page 5-105
for more information.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km), a
warning chime will sound and the Turn Signal On
message will appear on the Driver Information Center
(DIC) display. See “Turn Signal On” under
DIC Warnings
and Messages on page 3-79
for more information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever
to change the headlamps from low to high beam. Pull
the lever back and then release it to change from high to
low beam.
If you turn the vehicle off with the high beams on, the
next time you start your vehicle the low beams will
be on.
To re-activate high beams, pull lever toward you and
then push it forward again.
This light on the
instrument panel cluster
will be on, indicating
high-beam usage.
3-8
As light shines out from the HUD, it is possible for light
to shine back in. In rare occurrences, when the sun
is at a specific angle and position, the sun’s rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle’s angle to the
sun changes.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry it.
Notice:
When cleaning, be careful not to scratch the
HUD or camera lenses. Do not spray glass cleaner
directly on the HUD lens because the cleaner could
leak inside the unit and cause damage.
If the ignition is on and you cannot see the HUD image,
check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the proper height.
Ambient light in the direction your vehicle is facing
is low.
A fuse is blown. See
Fuses and Circuit Breakers on
page 5-105
.
Keep in mind that your windshield is part of the HUD
system. See
Windshield Replacement on page 5-56
.
The following Adaptive Cruise Control message
may appear in the HUD:
PEDAL APPLIED ACC OVERRIDE:
This message
indicates that you are pressing your foot on the
accelerator pedal and overriding Adaptive Cruise
Control. While you are doing this, the system will not
automatically apply the brakes. Once you remove your
foot from the accelerator pedal, Adaptive Cruise
Control will return to normal operation and be able to
apply the brakes, if needed.
You may also see an Adaptive Cruise Control active
symbol, alert symbol or vehicle ahead symbol. See
Adaptive Cruise Control on page 3-19
for more
information.
3-43
Accessory Power Outlet(s)
Your vehicle is equipped with accessory power outlets.
The outlets can be used to plug in electrical equipment
such as a cellular telephone, CB radio, etc.
Your vehicle has one outlet in front of the center
console, one in the center console lid and there may be
an additional outlet in the rear of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.
Notice:
Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain accessory power plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information on
the accessory power outlets.
Notice:
Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
Follow the proper installation instructions that are
included with any electrical equipment you install.
Notice:
Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
3-46
Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and cigarette lighter.
Notice:
If you put papers, pins, or other flammable
items in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put flammable items in
the ashtray.
Ashtray
The ashtray is located under the climate control panel on
the center console. Press on the door to release the
ashtray. The ashtray will automatically slide open for use.
To empty the ashtray with the ashtray in full open
position, locate the release button to the right of the ash
receiver and slide it to the right (in the direction of the
arrow). The ash reciever will unlock and lift slightly
and can then be easily removed from the housing. To
replace the ash receiver, place it into position in
the ashtray housing and push down firmly until it locks
into place.
There may also be ashtrays in the rear doors.
Cigarette Lighter
Notice:
Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
The cigarette lighter is located next to the ashtray. The

Notice:
If you connect a negative cable to the ECM,
ECM mounting bracket, or any cables that attach
to the ECM bracket, you may damage the ECM.
Always attach the negative cable to your vehicle’s
remote negative ground location, instead of the
ECM, ECM bracket, or any cables attached to the
ECM bracket.
{
CAUTION:
An electric fan can start up even when the
engine is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.
5-48
Electrical System
Add-On Electrical Equipment
Notice:
Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your
vehicle and the damage wouldn’t be covered by
your warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, see
Servicing
Your Airbag-Equipped Vehicle on page 1-62
.
Headlamp Wiring
The headlamp wiring has an individual fuse. An
electrical overload will cause the lamps to go on and off,
or in some cases to remain off. If this happens, have
the headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
5-104
Power Windows and Other
Power Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is fixed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating. If a fuse should blow, see your dealer
for service immediately.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without – like the radio or
cigarette lighter – and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
The fuses are located in three fuse blocks. One is
located in the engine compartment, on the passenger’s
side of the vehicle, and the other two are located
under the rear seat on both the driver’s and passenger’s
side of the vehicle.
5-105
Underhood Fuse Block
5-106
The underhood fuse block is located in the front of the
engine compartment on the passenger’s side of the
vehicle. See
Engine Compartment Overview on
page 5-12
for more information on location, and removal
procedure for the front compartment underhood sights
shields.
To access the fuses, push in the tabs located on each
side of the fuse block cover. Then, lift the cover off.

the vehicle.
To reinstall the rear seat cushion, do the following:
5-110
{
CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will not
provide the protection needed in a crash. If the
safety belt has not been routed through the seat
cushion at all, it will not be there to work for the
next passenger. The person sitting in that
position could be badly injured. After
reinstalling the seat cushion, always check to
be sure that the safety belts are properly routed
and are not twisted.
1. Buckle the center passenger position safety belt,
then route the safety belts through the proper slots
in the seat cushion. Do not let the safety belts
get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.
3. With the seat cushion lowered, push rearward and
then press down on the seat cushion until the
spring locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.
Rear Underseat Fuse Block
There is a fuse block located under the rear seat on the
driver’s side and passenger’s side of the vehicle. The
rear seat cushion must be removed to access the
fuse blocks. See “Removing the Rear Seat Cushion”
listed previously in this section.
To access the fuses, push in the two tabs, then lift the
