Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we tell you about something that
can damage your vehicle. Many times, this damage
would not be covered by your warranty, and it could
be costly. But the notice will tell you what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different
colors or in different words.
You'll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle may be equipped with components and
labels that use symbols instead of text. Symbols,
used on your vehicle, are shown along with the text
describing the operation or information relating to a
specific component, control, message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics in the Index:

ªEngine Compartment Overviewº

ªInstrument Panelº

ªComfort Controlsº

ªAudio Systemsº
Also see ªWarning Lights and Gagesº in the Index.

Ignition Positions
With the key in the ignition, you can turn the switch to
four positions.
The ignition switch is
located on the instrument
panel, to the right of the
steering column.
OFF: This is the only position from which you can
remove the key. Removing the key locks your ignition
and automatic transaxle.
NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.
ACC (Accessory): This is the position in which you
can operate your electrical accessories. With the key
in this position, the ignition and automatic transaxle
will unlock.
ON: This is the position to which the switch returns
after you start the engine and release the switch. The
switch stays in ON when the engine is running. But even
when the engine is not running, you can use ON to
operate your electrical accessories and to display some
instrument panel cluster messages and warning lights.

2-55
The exterior lamps control has three positions:
OFF:Pushing the control all the way in turns off the
exterior lamps.
Parking Lamps:Pulling the control out halfway will
turn on the parking lamps together with the following:

Taillamps

LIcense Plate Lamps

Instrument Panel Lights
Headlamps: Pulling the control all the way out turns on
the headlamps together with the previously listed lamps
and lights. See ªInterior Lampsº later in this section for
information on the instrument panel brightness control
and on the dome lamps. A warning chime will sound if
you open the driver's door when the ignition switch is
off and the headlamps are on.
Daytime Running Lamps / Automatic
Headlamp Control
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system's automatic headlamp control will
make your high
-beam headlamps come on at a reduced
brightness when the following conditions are met:

The ignition is on,

the exterior lamps control is off and

the gearshift is not in PARK (P).
When the DRL are on, only your high
-beam
headlamps, at a reduced level of brightness, will be on.
The headlamps, taillamps, sidemarker and other lamps
won't be on. Your instrument panel and cluster won't be
lit up either.
When it's dark enough outside, your high
-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on with
your headlamps will also come on.
When it's bright enough outside, your headlamps will go
off and your DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-83
Tachometer (If Equipped)
The tachometer displays
the engine speed in
thousands of revolutions
per minute (rpm).
3800 V6 Engine shown
NOTICE:
Do not operate the engine with the tachometer in
the shaded area, or engine damage may occur.
Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.

2-84
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle may also have a Driver Information Center
(DIC) that works along with the warning lights and
gages. See ªDriver Information Center (DIC)º in
the Index.
Safety Belt Reminder Light
When the key is turned to ON, a chime will come
on for about eight seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay
on for about 20 seconds,
then it will flash for
about 55 seconds.

6-25
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
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. 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 wouldn't
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean, drinkable water
and DEX
-COOL coolant.
