4. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
synchronizing the transmitter with the receiver.
Synchronization
Your remote lock control system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not send
the same signal twice to the receiver. The receiver will
not respond to a signal that has been sent to it more
than once.
To synchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for five seconds. In this time, the
doors should lock and unlock once. This confirms
the resynchronization.
If the doors do not lock and
unlock, see your retailer for service.

Trunk
To unlock the trunk from the outside, insert the key and
turn the trunZC lock cylinder.
It can be dangerous to drive with the trunk lid
open because carbon monoxide
(CO) gas can
come into your vehicle. You can’t see or smell
CO.
It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

’ . For quick cool-down on very hot days, use VENT with
’ . the temperature knob all the way in the blue area and the
; A/C and RECIRCULATION buttons pressed. If this
; setting is used for long periods of time, the air in your
vehicle may become too dry.
-1 For normal cooling on hot days, use VENT with the
’: temperature knob in the blue area and the A/C button
f pushed in. The system will bring in outside air and cool it.
Heating
On cold days, use FLOOR and the outside air button
I with the temperature knob all the way in the red area.
The system will bring in outside air, heat it and send it
to the floor outlets.
I Your vehicle has heat outlets that are directed toward
I
. : the rear seat. Keep the area under the front seats
’ I clear of obstructions so the heated air can reach the
rear seat passengers.
:If your vehicle has an engine coolant heater, you can
use it to help your system provide warm air faster
when it’s cold outside
(0 OF (- 18 O C) or lower). An
engine coolant heater warms the coolant your engine
and heating system use to provide heat. See “Engine
’ . Coolant Heater” in the Index.

Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows.
For each setting, adjust the temperature
control as desired.
To defrost the front window quickly, rotate the
temperature control knob all the way in the red area.
Use DEFROST and adjust the fan to the highest speed.
To warrn passengers while keeping the front window
clean, use DEFOG.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located
on the outside of the side instrument panel vents. To
defrost the side windows rotate the temperature control
knob all the way in the red area. Use
FLOOR and adjust
the fan to the highest speed. To control fogging of the
windows rotate the temperature control knob all the
way in the red area. Use DEFOG and adjust the fan
to the highest speed.
To defog the side windows while using air conditioning
use BI-LEVEL and adjust the fan to the highest speed and press the
A/C button. For added airflow to the side
windows aim the side vents toward the windows and
close the center vents.
RECIRCULATION will not work in DEFROST and
DEFOG. This is done to prevent recirculation of humid
inside air and allow the system to work properly.

Rear Window Defogger
The rear window defogger
uses a warming grid
to remove fog from the
rear window.
Press the defogger switch. The indicator light will
glow. The rear window defogger will turn itself
off
after about 10 minutes after the first time the button is
pressed, and after
5 lninutes each additional time the
button is pressed. You can turn the defogger off by
pressing
the button again or turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don’t use a razor blade or anything else sharp on
the inside
of the rear window. If you do, you
could cut
or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle.
Your vehicle also has the
flow-through ventilation system.
Your vehicle’s flow-through ventilation system supplies outside
air into the vehicle when it is moving. Outside
air will also enter the vehicle when the
air conditioning
fan is running.

If you drive regularly in steep count., or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 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 downhills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long
hill.
I = ~ ~ ~~ ~~ ~
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
hiIl. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope.
0 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.
could be something in your lane, like a stalled car or
an accident.
0 As you go over the top of a hill, be alert. There
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passiag or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fans

Ik I
/!II CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not runnimg
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,
don’t
do anytlung else until it cools down.

The coalant level should be at or above FULL COLD
m-ark .or slightly higher.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.
Heater and radiator hoses, and 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 leak. If you run
the engine, it could lose all coolant. That could
cause
an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
1 NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
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 aren’t, your vehicle needs service.

How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD mark or slightly higher, add a
50/50 mixture of clean water (preferably distilled) and
DEX-COOL’ coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
pressure cap,
is cool before you do it. (See “Engine
Coolant’’ in the Index for more infomation.)
I
Steam and scaldmg liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never
turn the cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge
tank pressure
cap to cool
if you ever have to turn the
pressure cap.
5-17

I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
You can be bmrned if you spill coolant on hot ,
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
1. You can remove the coolant mge tank pressure .cap
when the cooling system, inclu-ding the coalimt surge
tank pressare cap and upper radiatox hose, is no
longer hot. Tm the pressure cap slowly about
one-quafter
turn to the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.

5. Then replace the pressure cap. Be sure the pressure
cap
is tight.
Check the level in the age tank when the cooling
system has cooled down. If the coolant isn't at the
proper level, repeat Steps
1 to 3 and reinstall the
pressure cap or see
your retailer.
