To &dock the liftgate from the outside,
insert the door key and turn it
clockwise. Then
lift up the bottom of
the liftgate.
Be sure there are no overhead
obstructions before you open the
liftgate. You could slam the liftgate into
something and break the glass.

monoxide
(CO) gas can come into
your vehicle.

P (Park) or N (Neutral) for the liftgate
Make sure all other windows are
shut.
Turn the fan on your heating or
cooling system to its highest
speed (that will force the outside
air into your vehicle).
If you have air vents on or under
the instrument panel, open them
all the way. Press the
yellow liftgate release button
located in the glove box to release the
liftgate.

Climate Control System
With this system, you can control the
ventilation and heating in your vehicle.
Your vehicle
also has the flow-through
ventilation system described later in this
section.
Lever Controls: The upper lever
changes the functions of your system.
The lower lever changes the temperature
of the air coming through the system.
Slide the upper control lever to
OFF to
turn
off the system.
3f : Sets the fan speed. To select the
force of air you want,'turn the knob.

VENT Use when outside temperatures
are mild and little heating or cooling is
needed. Air flow is through the
instrument panel outlets. Set the lower
lever to the temperature desired.
B/L (Bi-Level): Use on cool, but SUMY
days. This setting brings in the outside
air, but directs it in
two ways. The cool
air is directed to the upper portion of your
body through the instrument panel outlets,
but slightly warmer air is directed through
the heater ducts and defroster vents. At
times, this temperature difference may
be more apparent than others.
HTR (Heater): This setting brings
heated air through the heater ducts, and
some through the windshield defroster
vents.
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Block Heater.
BLEND: This setting divides the air
flow equally between the heater ducts
and the windshield defroster vents.
DEF (Defrost): This setting directs
most air through the windshield
defroster vents, and some through the
heater ducts.
Defogging Windows
Slide the lower lever to HOT. To defog
the windows, set the upper lever to
DEF
and turn the fan control to HI.

Air Conditioning System
(OPTION)
The air conditioner and heater work
best if you keep your windows closed
while using them. Your vehicle also has
the flow-through ventilation system
described later in this section.
Lever Controls: The upper lever
changes the functions
of your system.
The lower lever changes the temperature
of the air coming through the system.
Slide the upper control lever to
OFF to
turn off the system.
I 3f : Selects the fan speed. To select
the force of air you want, turn the knob.
The fan is always running unless the
upper lever is moved to
OFF.
Air Conditioning
The upper lever has three air
conditioner settings.
On very hot days,
open the windows long enough to let hot
inside air escape. This reduces the
amount of work your air conditioner's
compressor will have to do, which
should help fuel economy.
A/C (Air Conditioning): Press this
button to operate the air conditioner
compressor. The indicator light will
glow when the button
is pressed. The air conditioner compressor
operates
whenever the
AIC button is pressed. It
also operates automatically (and the
light will glow) when in the
MAX
setting, or in the DEF (Defrost) setting
when the outside temperature is higher
than about
40°F (4.5"C).
MAX (Maximum): Use for maximum
cooling. This setting recirculates much
of the air inside your vehicle
so it
maximizes your air conditioner's
performance and your vehicle's fuel
economy.

Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain. If you drive regularly in steep
country, or if you’re planning to visit
there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and
also the
brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain roads.
Know how to go down hills. The most
important thing to know is this: let
your engine do some
of the slowing
down. Don’t make your brakes do it
all. Shift to a lower gear when you go
down a steep or long hill. That way,
you will slow down without excessive use of your brakes.
I 54
r If you don’t shift down, your
brakes could get
so hot that
they wouldn’t work well. You
would then have poor braking or
even none going down a hill. You
could crash. Shift down to let your
engine assist your brakes on a
steep downhill slope.
Coasting downhill in
N (Neutral) or with the
ignition
off is dangerous. Your
brakes will have
to do all the work
of slowing down. They could get
so hot that they wouldn’t work
well.
You could crash. Always
have
your engine running and your
vehicle in gear when you go
downhill.
Know how to go uphill. You may want
to shift down to a lower gear. The
lower gears help cool your engine and
transaxle, and
you can climb the hill
better.
Stay in your own lane when driving on
two-lane roads in hills or mountains.
Don’t swing wide or cut across the
center of the road. Drive at speeds that
let you stay in your own lane. That
way, you won’t be surprised by a
vehicle coming toward you in the
same lane.
It takes longer to pass another vehicle
when you’re going uphill. You’ll want
to leave extra room to pass.
If a
vehicle is passing you and doesn’t have
enough room, slow down to make it
~ easier for the other vehicle to get by.

sign
of steam, try this for a minute or so:
1. If you have an air conditioner, turn it
2. Turn on your heater to full hot at the
off.
highest fan speed and open the window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine
runs slower).
If
you no longer have the overheat
warning, you can drive. Just to be safe,
drive slower for about ten minutes. If
the warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over, stop, and park your vehicle right away. If there’s
still no sign of steam, you can
idle the engine for two or three minutes
while you’re parked, to see
if the
warning stops. But then, if you still have
the warning, TURN
OFF THE
ENGINE AND
GET EVERYONE
OUT OF THE VEHICLE until it cools
down.
You may decide not to
lift the hood but
to get service help right away.
If you have
a 2.2L L4 engine, your
engine coolant system
will have a
coolant recovery
tank. If you have a 3.1L
V6 engine, your engine coolant system
will have a coolant surge tank.
There are important differences between
these two cooling systems. Read this section carefully.

The coolant level should be at or above
FULL COLD. If it isn't, you may have
a leak
in the radiator hoses, heater

somewhere else in the cooling system.
II Heater and radiator hoses, and
L other engine parts, can be
very hot. Don't touch them. If you
do, you can be burned.
Don't run the engine if there is a
