Liftgate
{CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle.
You cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the liftgate open or if
electrical wiring or other cable connections
must pass through the seal between the
body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select
the control setting that will force
outside air into your vehicle. See
Climate Control System on page 155.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 121.The liftgate on a hatchback or wagon can be
locked and unlocked from outside of the vehicle
by inserting the key into the lock and turning it.
The Remote Keyless Entry transmitter, if the
vehicle has one, can also be used. Then pull up
the handle above the license plate to open
the liftgate.
When closing the liftgate, close it from the center
to make sure it fully latches.

When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
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.
Ashtray(s) and Cigarette Lighter
The front ashtray is located at the lower part of
the center of the instrument panel. To remove the
bin from the front ashtray for cleaning, open
the ashtray fully, lift up the inner bin and then pull
the bin out.
The rear ashtray is located at the bottom of the
rear center console. Pull the ashtray toward
the rear of the vehicle to open it. To remove the
rear ashtray, press in the retaining spring and pull
the bin out.Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
The cigarette lighter is located to the right of the
front ashtray. To use it, turn the ignition to ACC or
ON, push the cigarette lighter in all the way and
let go. When it is ready, it will pop back out
by itself.
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. Do not hold a
cigarette lighter in while it is heating.

Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. In any setting other than off, the fan
will run continuously with the ignition on. The fan
must be on in order for the air conditioning
compressor to run.To change the current mode, select one of the
following from the middle knob:
E(Vent):This mode directs air to the instrument
panel outlets.
((Bi-Level):This mode directs about half of the
air to the instrument panel outlets, and then
directs the remaining air to the floor outlets.
5(Floor):This mode directs most of the air to
the floor outlets. Some of the air will also be
directed to the windshield, instrument panel side
outlets, and the rear outlets. Be sure to keep
the area under the front seats clear to allow the
flow of air to the rear compartment.
The middle knob can also be used to select the
defog and defrost modes. Information on defogging
and defrosting can be found later in this section.
Temperature Control:Turn the right knob
clockwise or counterclockwise to manually
increase or decrease the temperature inside your
vehicle. Turn the knob to the blue area to get
cool air and to the red area to get warm air.

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant
temperature gage.
With the ignition turned
to ON, this gage
shows the engine
coolant temperature.
If the gage pointer moves into the red area, your
engine is too hot. It means that your engine
coolant has overheated.
If you have been operating your vehicle under
normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
SeeEngine Overheating on page 271.
Tire Pressure Light
This light comes on
briefly when you turn
the ignition to RUN.
This light will also come on when one or more of
your tires are significantly underinflated.
Stop and check your tires as soon as it is safe to
do so. If underinflated, inflate to the proper
pressure. SeeTires on page 303for more
information.
This light will flash for about 75 seconds and then
stay on if a problem is detected with the Tire
Pressure Monitor system.
SeeTire Pressure Monitor System on page 312
for more information.

Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for five years
or 150,000 miles (240 000 km), whichever
occurs first, 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 271.
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.
What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant which will
not damage aluminum parts. If you use this coolant
mixture, you do not need to add anything else.
268

Adding Coolant
If you need more coolant, add the proper
DEX-COOL®coolant mixture at the coolant surge
tank, but only when the engine is cool. If the
coolant surge tank is empty, a special fill
procedure is necessary. SeeEngine Overheating
on page 271for instructions on “How to Add
Coolant to the Coolant Surge Tank.”
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. SeeEngine
Coolant Temperature Gage on page 171.
271

{CAUTION:
An electric engine cooling fan under the
hood 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.
If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
Make sure that the air conditioning is turned off.
The coolant level should be between the Minimum
and Maximum marks on the coolant surge tank
when the engine is cool. 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 fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.
